2.0 Grooved Pipe Coupling System

General Information

The Shurjoint* grooved and hole-cut couplings and fittings available from King Systems

provides you and your customers with a high quality advanced mechanical piping system

with proven versatility and reliability. King grooved pipe coupling products are suitable for

use in a variety of piping applications which include industrial fluid transport, fire protection,

heating, and air conditioning. King grooved systems offer a fast and easy assembly system,

that can be installed 3-4 times faster than welding, and is more reliable than threading or

flanging. The result is that using grooved pipe systems gives the lowest total installed cost,

saving in both time and money.

The King Systems range of couplings are designed to mechanically join standard roll-

grooved or cut-grooved pipe. The pressure responsive rubber gasket provides a leak-tight

seal when the housing segments are tightened. Pipe end preparation is fast and easy and

can be done in the workshop or on the job site. A Grooved system is an ideal means of

connecting pipe utilising roll-groove technology.

An extensive range of hole-cut mechanical tees provides a fast and easy method to install

mid-point branch lines and outlet connections without welding. A hole is first cut or drilled

at the desired outlet location. The mechanical tee is then positioned in place. As the

housing is tightened the pressure responsive moulded gasket moulds to the pipe OD,

forming a leak-tight seal.

King System flange adaptors from grooved components or pipe adapt to or make direct

connections to ANSI Class 125 or Class 150, PN10, PN16 and Table E flanged components

within a grooved piping system. This allows for fast and easy connections to valves, pumps

and flanged piping systems. A full line of Grooved fittings and components including short

radius bends and threaded branch reducing tees are supplied to satisfy the widest range of

piping applications.

Manufacturing processes meet or exceed the ISO-9002 quality assurance standards

and are certified by Lloyd’s Register Quality Assurance Ltd. (LRQA). To allow use in

fire protection, King systems products intended for this application have also passed the

performance requirements of UL, UL of Canada, FM, LPC and VdS. This is your assurance

that King products are manufactured to internationally recognized quality standards. Our

strict quality control system ensures continued product performance and reliability. For

Coupling HousingsAll housing segments are made of ductile iron conforming to ASTM A536 Gr.

65-45-12 or BS EN 1563-97 Gr. EN GJS 450-10 and have a minimum tensile

strength of 65,000 psi (448 Mpa). The strength of the housing exceeds the

rated working pressure by 4-5 times. In the foundry each melting charge and

pouring batch is monitored and tested using the most advanced computerized

testing equipment. Couplings and fittings are available painted Red (RAL

3000), hot dipped galvanized or epoxy finished. The SS-8 Range of stainless

steel couplings are ideal for joining thin wall stainless steel pipe.

Rigid Couplings and Flexible CouplingsKing systems offers you both rigid and flexible type couplings to meet your

specific piping requirements. Either type of coupling can be used in

applications where rigidity or flexibility are not important design factors.

Both types of couplings use the same Standard or GapSeal™ rubber gaskets

and can be used on standard roll or cut grooved pipe. To ensure correct

coupling selection consult pressure ratings.

Flexible CouplingsKing systems flexible couplings can be used in a variety of piping

applications such as commercial, industrial, mining, construction, process

piping, fire protection and other applications where controlled angular, linear

and rotational movement is desired. Flexible couplings also provide excellent

noise and vibration attenuation characteristics, though these features need

to be considered when determining hanger and support spacing and

location. The Class 7705 is recommended for moderate pressure services

while the Class 7707 is recommended for higher pressure services.

Rigid CouplingsBoth the Class 7771 and K-9 couplings provide a rigid, locked-in connection

and are recommended in applications where minimal expansion, contraction

or linear movement is desired. Both couplings are useful in mechanical

rooms and risers where rigidity is required. The Class 7771

is designed for use in moderate or higher pressure applications, while the

Class K-9 is designed for use in moderate or lower pressure applications

such as fire protection services.

The rigidity in these couplings is achieved by a number of built-in teeth

(“Dogtooth”) that firmly grasp the pipe, thus eliminating undesired flexibility

and by the tongue and groove(T&G) mechanism that can accommodate a

range of pipe grooves that may not always be consistent due to the machine

or operator.

All sizes of the Class K-9 and all sizes up to 8” of the Class 7771 feature

both the “Dogtooth” and the T&G mechanism. Class 7771 sizes 10” and

above features the T&G mechanism.

The rigid couplings are designed to provide rigidity to permit hanging to

ANSI B31.1 Power Piping Code, ANSI B31.9 Building Services Piping Code

and NFPA 13 Sprinkler Systems.

The coupling is designed so that the housing keys fit into and securely grip

the full circumference of the grooved pipe. When the housing segments are

tightened around the pressure responsive gasket the result is a strong leak-

tight seal. ISO certification and our dedication and commitment to quality

assure you will be connecting with the best.

Grooved End FittingsA comprehensive range of grooved end

fittings are available providing the ultimate in

flexibility. Installation is fast, simple and reliable.

The grooved system technology, creating a

union coupling at every joint means system

change, extension and maintenance could not

be easier. The range of short radius fittings

optimises system design where space is restricted. Fittings are available

painted Red (RAL 3000), hot dipped galvanized or epoxy finish.

GasketsGaskets utilised in the King Grooved System are designed to provide a

pressure responsive leak-tight seal. The gasket is first stretched over the

adjoining pipe ends between the grooves forming the initial seal. The

housing segments are then positioned around the gasket and into the pipe

grooves. As the housings are tightened the pressure responsive gasket is

compressed to form the leak-tight

seal. The strength of the seal is further

enhanced by internal line pressure

that creates downward pressure on

the lips of the gasket. The gasket also

seals well under vacuum conditions

(up to -10 in. Hg or -35 kPa) that may

occur when a system is drained.

Gasket SelectionTo assure the maximum gasket life for your intended service, proper gasket

selection is essential when ordering. Many factors must be considered when

determining the best gasket for the intended application. The most important

factors are those of temperature, concentration of product, and duration and

continuity of service. Higher temperatures act to degrade and reduce the life

of the gasket, thus careful consideration should be given to any applications

where high temperature service is a

constant factor. Recommendations to

assist the choice of gasket are included

on page 27-28 of this catalogue.

Bolts and NutsKing Grooved pipe Couplings utilize carbon steel oval neck track bolts

and heavy-duty hexagonal nuts. The bolt materials conform to ASTM A449

(A183 Gr. 8 for 3/4“ bolt sizes and larger) or BS970 Part1 (Gr.605M36

or Gr.709M40) and have a minimum tensile strength of 110,000 psi (758

Mpa). The bolts are heat-treated and zinc electroplated. Hot-dipped zinc

galvanized bolts and nuts are also available upon request. The oval neck

track bolts mate into the oval holes in the housings to allow for easy

tightening using only a wrench.

Approvals and ListingsAll products are subject to strict quality control including hydrostatic testing.

Where applicable King systems products have also been submitted to UL,

FM, LPC and VdS and received approvals listing for use in fire protection

applications. For details of the specific approvals status for individual products

The King grooved piping system is simply the most versatile, economical

and reliable system available. This system can be installed 3-4 times faster

than a welded system and offers clear benefits to the designer, installer and

owner. Whether you require flexibility or rigidity, have concerns with seismic

stress, electrical continuity, noise and/or vibration attenuation, the King

System range caters for your needs. The grooved system technology is

unmatched for ease of access for cleaning, maintenance, design changes

or system extension.

RigidityWhere a rigid connection is desired

we recommend the King rigid

coupling, Class 7771 or Lightweight

Rigid Coupling Class K-9. The unique

Dogtooth™ design in combination

with positive locking tongue and groove feature provides positive clamping

of the pipe to resist torsional and/or flexural loads. Bolts must be tightened

equally and evenly such that the gap between bolt pads are the same width

for optimum performance.

Internal & ExternalRestraintThe coupling keys engage the full

circumference of the grooves. This

provides significant pressure restraint

and end load capabilities to withstand

pipe movement from various internal and external sources.

Easy AccessWith the removal of just a few bolts

the Grooved System technology

allows easy access to the system

allowing for cleaning, maintenance,

changes or system extension.

Piping systems must always be de-pressurized and drained before

disassembly and removal of components.

• ASTM A183: Specification for Carbon Steel Track Bolts and Nuts

• ASTM A449: Specification for Quenched and Tempered Steel Bolts and Studs

FlexibilityWhere a flexible connection is

desired we recommend either Class

7705 or Class 7707. These couplings

feature excellent strength and

flexibility to deal with a variety

of factors including expansion, contraction and deflection caused by

temperature changes, seismic tremors and or other sources of vibration.

With the use of flexible couplings you may be able to reduce or eliminate

the need for expensive expansion joints, vibration attenuators or loops in

your system. Bolts must be tightened equally and evenly until the bolt

pads achieve firm metal to metal contact.

Alignment EaseThe King grooved system allows

for the rotation and alignment

of pipe, valves and fittings prior

to tightening the housing bolts.

This feature can also reduce tension

between piping components.

Noise & VibrationAbsorptionThe design and construction of a

grooved system utilizing elastomeric

gaskets reduces noise and vibration

transmissions.

Electrical ContinuityCouplings with rubber gaskets are likely to function as an insulator. Where

electrical continuity is required, our King electrical continuity clip (option) will

restore continuity to the system. The electrical continuity clip satisfies IEE

Wiring Regulations.

Reducing CouplingsClass 7706

1) Working pressure and/or End Load are total pressure and/or load permissible when mounted on standard weight steel pipe, standardroll or cut grooved. Test pressure fields may be increased to 1.5 times the max. working pressure shown above. For working pressurein other pipe schedules, contact your King Distributor for details.

2) Vds Listed to 2.0 MPa or1.2 MPa only.

The Class 7706 Reducing

Coupling allows direct

reduction on a piping run

and can eliminate the need

for a concentric reducer and

couplings. The specially

designed gasket prevents

the smaller pipe from

telescoping into the larger

pipe during vertical assembly.

Flange Adaptors and Flange WashersClass 7041-E

Closure Tabs

Integral closure tabs located on the flange OD help to facilitate

alignment and assembly. When required use a C-clamp, wrench or

pliers to draw the closure tabs towards each other until the flange

holes are aligned, then insert the bolt.

Flange Washer

The Class 7041 flanges require

a hard flat surface for effective

gasket sealing. A flange

washer is required and should

always be used when the

mating surface is not

adequate, for example the

serrated faces of some valves

or the rubber-faced or rubber-

lined flange of the wafer valve.

Important Notes

1. The Sealing Surface of the mating flange, the area shown

between D and E in the top illustration, shall be free from

gouges, undulations or deformities of any type to secure

optimum sealing.

2. Class 7041 flanges have small triangular teeth inside the

key shoulder to prevent the pipe from rotating. The teeth

should be ground off when mating to a rubber-lined flange,

and or light wall Schedule 5 pipe.

3. Class 7041 flanges require a hard flat surface for effective gasket

sealing. A flange washer shall always be used when mating to:

3-1) A rubber-faced or rubber lined flange, as widely seen in

wafer valves (lug valves): See illustration Note 3-1.

3-2) A serrated face flange: In this case, use a regular flange

gasket as well as a flange washer as illustrated in Note 3-2.

4. When attempting to use a Class 7041 flange against a butterfly

valve or ball valve, make sure that the outside dimensions do

not interfere with the valve actuator or valve handle.

5. Class 7041 flanges shall not be used as anchor points for tie-

rods across non-restrained joints. Do not use Class 7041 flanges

within 90 degrees of one another on standard fittings when the

outside dimensions cause interference.

as equivalent meters (feet) of straight pipe.

For the branch of a tee that is reduced in

size, use the value that corresponds to the

branch size. For example, the branch value

of a 4" x 4" x 3" tee is 3.9 metres (12.8

feet). For fittings not listed in this table,

the equivalent length of straight pipe

can be estimated from the data provided.

For example, the flow resistance of a

22-1/2° elbow is approximately one half

that of a 45° elbow.

Bolt Fastening Torque for Mechanical Tees & Crosses, Class 7721, 7722 andSaddle-Let Tee Class 723

All mechanical tees and crosses are designed with a gap

between the bolt pads. Do not attempt to bring the bolt

pads together (metal-to-metal) when tightening the

housings. Excessive torque may result in joint failure.

Apply the recommended bolt fastening torque given in

the table below.

Mechanical Tee

The King System hole-cut mechanical tee provides a fast and easy

mid-point branch outlet without welding. First a hole is cut or

drilled at the desired outlet location. The mechanical tee is then

positioned so that the built-in locating collar fits within the hole.

As the housing bolts are tightened the pressure moulded gasket

forms a leak-tight seal. Use of the King mechanical tee can

eliminate the need for multiple couplings and fittings. Bolts should

be tightened equally and evenly.

A comprehensive choice of mechanical tees are available in

the King range:

Class 7721: Threaded outlet, NPT or ISO pipe threads

Class 7722: Cut-grooved outlet

Class 723: Saddle-Let; Small mechanical tee with

threaded outlet, NPT or ISO pipe threads

(For Fire protection and low to medium pressure applications).


Mechanical Cross Connections

A mechanical cross connection can be made by combining two

mechanical tee upper housing segments. While the housing

segments must be the same size the branch outlets can be of

the same or differing sizes and configurations as shown.

Caution: Piping practices require that main and branch

connections are at a true 90º angle. Also be certain that the

locating collar is securely positioned inside the outlet hole before

tightening the housing. When mechanical tees or mechanical

crosses are used as transition pieces between two runs, the tees or

crosses shall be assembled prior to making the branch connections.

Saddle-Let Small Mechanical TeeClass 723 Threaded Outlet

Continuity Clip

The Class 723 Saddle-Let Small Mechanical Tee is the

ideal outlet fitting for direct connections to sprinkler

heads, drop nipples and/or gauges. No need for welding,

just cut or drill a hole at the desired outlet location.

Position the Saddle-Let so that the locating collar fits

within the hole and secure with the U-bolt and nuts. The

Saddle-Let comes with a standard black finish or as an

option can be supplied electro zinc plated or painted red.

The Saddle-Let allows full bore flow and is pressure rated

up to 1.2 MPa (175 psi). Threaded outlets available with

ISO pipe threads.

Couplings with rubber gaskets are likely to function as an

insulator. Where electrical continuity is required, our King

continuity clip will restore electrical continuity to the

system. The electrical continuity clip satisfies IEE Wiring

Regulations.

Gasket Selection

To assure the maximum gasket life for your intended service,

correct gasket selection is essential. Many factors must

be considered when determining the best gasket

for the specific application. The type of fluid,

temperature, duration and continuity of service

are primary factors for selecting the optimum

gasket for a specific service. A guide to gasket choice

is given below and in the Recommendation List to be found in

the Design and Technical Information pamphlet, or if in doubt

contact your King distributor.

Specify the gasket when ordering and always check that the colour

code on the gasket is for the intended service before installation.

Table 1 Gaskets - General Data and Service Recommendations

Note

The temperature, chemical composition and concentration of the transported product and the in-service environment all affect the

durability of gasket compounds over time. Always refer to the Gasket Selection Guide in the Design & Technical Information handbook

before selecting the appropriate gasket and grade.

King System gaskets are not recommended for certain applications. If in doubt, or when the intended product, service condition or

temperature is not listed or recommended contact your King Systems Distributor for guidance. Ensure compatibility of the King Coupling

housing or fittings and any related components for the service application prior to use.

Notes. Elastometric Gaskets are unsuitable for use directly on rubber lined valves. It is recommended to use the GapSeal™ gasket for dry

fire sprinkler systems. All Gasket Styles are available in E, T, O, & L material grades.

Gasket Styles

Standard Gasket

Standard gaskets are the most commonly used both in rigid and flexible couplings,

and are suitable for a wide range of applications in fluid transport.

GapSeal™ Gasket

The GapSeal™ gasket has a solid centre leg that fits flush over the adjoining pipe ends.

When the coupling is tightened the gasket is compressed over the pipe ends forming a

leak-tight seal. The GapSeal™ gasket prevents fluid from entering the gasket cavity. The

GapSeal™ gasket is recommended for dry fire sprinkler systems, lined pipe connections

and other applications where fluid retention in the pipe line may be hazardous.

Reducing Coupling Gasket

The reducing coupling gasket features a unique built-in retainer, that prevents smaller

pipe from telescoping into larger pipe during vertical assembly. This gasket also provides

generous space for pipe insertion and can eliminate the need for steel plates or washers

which can hinder installation.

Flange Gasket

The Flange gasket is designed to seal on the pipe end and on the flange.

Suitable for the Class 7041 flanges only.

Outlet Coupling Gasket

Designed for use with Class C-7 outlet coupling. The gasket seals on the ends of the pipes

to be connected and also in the neck of the outlet.

Mechanical Tee Gasket

This C-shaped pressure responsive gasket is designed for use with Class 7721 and 7722

mechanical tees for sealing on the curved exterior of the pipe.

The Class 723 Saddle-Let gasket is an integral gasket consisting of a solid cylinder and a

curved fringe. This gasket seals on a wide range of pipe surface with permanent compression.

The information presented in this catalogue is intended to assist installation and

piping system product selection when using King products for their specified application.

This information is not intended in any way as a substitute for the employment of

approved competent professional system design and installation expertise which is

an obvious prerequisite.

If you have any doubt over the suitability of any product supplied by King Systems for

the intended application contact your King Distributor for advice before proceeding.

King Grooved products and Pipe Selection

King grooved pipe couplings are designed for use only with approved standard

and recommended pipe, grooved in accordance with the relevant published specifications

and with the King System range of grooved end couplings, fittings, and related grooved

end components. Unless specifically specified King grooved pipe couplings must not be

used to connect with plain end pipe and/or fittings.

Gasket Selection and Use

The correct gasket must be selected and specified to suit the application intended.

Full details are given of permitted applications and allowable service conditions for

different gasket types and materials in the Gasket Selection Chart included in the

Design and Installation handbook. If the intended service application is not included

in the Chart contact your King Distributor before proceeding.

Gaskets must always be lubricated with a thin, uniform coating of lubricant to assist

location and to avoid any pinching of the Gasket during assembly that may cause damage

or leakage. Use approved King Gasket lubricant or equivalent vegetable soap based

lubricant for wet systems. For dry systems silicone based lubricant can be used. Do not use

petroleum based lubricants under any circumstances.

The coupling gasket must be positioned centrally between the two pipe grooves and

without overlapping into the groove(s).

Note

The technical and performance data, weights, dimensions and specifications published in

this catalogue supersede all previously published data. All data contained herein, is subject

to change without notice and including the right to alter product specifications, designs

and equipment without notice and without incurring obligation.
