The stainless steel UNI-Coupling has a number of

advantages compared to similar couplers. The UNI-

Coupling has two specifi c parts making this coupler

unique. A patented seal that eliminates the risk of leakage

and a special shaped anchoring grip ring, which ensures

a reliable, restraint connection.

Connecting pipes better, quicker and safer …With the UNI-Coupling you connect pipes the easy way. Better than a threaded connection, quicker than a welded connection and safer than a flanged connection.

Moreover the UNI-Coupling can be installed fast and

thanks to the wide range, it can eff ortlessly connect

diff erent types of pipes with various outside diameters.

Better, quicker and safer than you are used to. The UNI-

Coupling off ers you an easy to install, time saving and

money saving solution.

Two types of UNI-CouplingUNI-Coupling applies one unique technical principle in

two basic types of products and is available for any type

of pipe combination to be connected. Based on the

well proven coupling technology, we combine various

pipe materials for different applications.

UNI-Grip / UNI-Plastgrip / UNI-Combigrip

Axially restrained

UNI-Flex / UNI-Rep

Axially flexible

Safety and reliability has been proven and

certified by public authorities, insurance companies,

technical inspectors and licensing institutes for all the

major industrial sectors. You can rely on the

UNI-Coupling.

High flexibility and safety marginsHigh flexibility and safety margins: the basic principle of UNI-Coupling.

The patented seal with an integrated compensation solutionOnce installed, the unique seal with coupling compensation

beads makes the use of stainless steel inserts

superfluous in most applications. This actively prevents

potential corrosion problems.

There will be a progressive sealing effect due to the

wedgeshaped structure. This ensures a watertight sealing

even at high pressures. Due to the solid seal design

(without thin lips) robustness of the seal guarantees

durability even under harsh conditions.

Progressive anchoring with spherical profileInternal pressure or axial forces cause tensil loads which

is absorbed by the progressive anchoring ring. The teeth

Patented seal

Axially restrained

Progressive anchoring

Axially flexible

show a spherical profile which ensures a high tip

hardness and therefore a solid grip even at the toughest

type surface. Especially important when it comes to thin

walled stainless steel or cast iron pipes.

Thanks to the simultaneous cuts of the teeth (5°) a firm

grip on other surfaces like metallic coated pipes is also

guaranteed. This because the teeth penetrate the outer

surface and anchor in the pipe wall.

Fire protection for your safetyFor applications in which a fire protection must be

guaranteed we meet the high demands of the shipbuilding

industry according to ISO 19921/19922.

These high requirements are ensured by an additional

fire protection.

Strip insertsStrip inserts protect the sealing sleeve against mechanical

or chemical damage in the pipe end area.

Strip inserts are required for:

• External pressure (e.g. underwater pipeline)

• Vacuum ≥ 0.5 bar A pressure (e.g. suction line)

• Swelling of the rubber caused by contact with chemicals

Subsequent installation of strip inserts for all types of couplings is possible. Strip insert are made of 316 Ti (1.4571) quality steel and capable of handling high tem-perature, vacuum and external pressure.

Fitting plier / fitting beltFor convenient assembly of UNI-Rep couplings we

recommend using a fitting plier. The plier uses the bores in

the housing to close the coupling which enables you to man-

ually tighten the bolts. For bigger diameters (>300 mm)

use a fitting belt.

Torque wrenchAlways assemble UNI-Couplings with a torque wrench.

The correct torque is indicated on the housing of each

UNI-Coupling. In using a torque wrench you ensure that

the UNI-Coupling is not overstressed.

Strip inserts are only required for above mentioned application

Angular deflection

UNI-Couplings cover angular deflection of pipes up to 2°

(4°) in any direction.

The 2° angular deflection corresponds to 35 mm per

meter of pipe length.

The installation is very easy and there is no need for

costly pipe alignment.

It is possible to fit the pipe with angular deflection and to

use the joint for dynamic angular movement under working

conditions after installing the pipe system.

Example: Ground settling

Note: Pipe end gap C max must always be kept.

30

UNI-Couplings generally allow misalignment of the pipe

axis. However, we recommend avoiding misalignment

wherever possible or absorbing it either with an angular-

ity of max 2° or by using an intermediate piece.

Axial misalignment

Where the pipeline guides are sufficiently spaced from

the pipe end, the butt ends can be rectified by hand with

low force, approx. 500N. The remaining axial misalign-

ment after tightening the lock bolts is minimal. For such

an application a larger misalignment prior to connecting

can be permitted, keeping the following rule in mind:

A misalignment of up to 1% in the fitted position has no negative influence on the function of UNI-Flex and UNI-Rep pipe couplings and is therefore tolerable up to pipe OD of 300 mm.

Under such conditions a slight sloping of the coupling on

the pipe ends has to be expected.

Since "zero misalignment“ is hard to realize, a minimal mis-

alignment is tolerated. The following rule serves to

explain the limits of what is tolerable, with the aim of

keeping axial misalignment as small as possible.

‘For fixed pipe ends, a misalignment of up to 1% (max. 3 mm) of corresponding pipe OD can be tolerated without any restrictions. It does not affect the correct fitting of the UNI-Coupling’.

31

Retrofitting pipe sections and fittings

Fitting (T), position and direction of the branch are freely selectable

Valve with plain ends, rotatable to any position

Thanks to their large clearance and allowable fitting gap

as well as the wide tolerance range, UNI-Couplings are

predestined as an ideal construction element for

retrofitting pipe sections and fittings during repair work

or for changes in the pipeline direction.

Pipe section for existing or new pipelines

UNI-Coupling pipe couplings do not absorb bending or torsion forces. Pressure lines must be supported, anchored and guided.

Page 32: Technical Manual - UNI-Coupling · With the UNI-Coupling you connect pipes the easy way. Better than a threaded connection, quicker than a welded connection and safer than a flanged

32

Axial movement/change in length

Temperature changes in pipeline systems cause axial

movement and tensile or pressure stress, which must be

compensated by adequate countermeasures.

UNI-Coupling pipe couplings do not absorb bending or torsion forces. Pressure lines must be supported, anchored and guided.

UNI-Flex and UNI-Rep pipe couplings are able to

compensate axial movement of straight pipe sections, up

to 20 mm depending on the size of coupling.

• compensation of axial movement

• no abrasion on the sealing sleeve

• escaping space for rubber expansion under

temperature

• stress-free pipeline without additional means

(see below)

Note: Pipe end gap C max. must always be kept.

Larger axial movements need compensation, such as traditional compensators

33

Anchor points and guides with axial movement Clever fastening of pipe sections which are exposed

to axial movement due to temperature influences

can be divided into ‘movement units’ and joined

very economically with UNI-Flex and UNI-Rep pipe

couplings as compensators.

UNI-Coupling pipe couplings do not absorb bending or torsion forces. Pressure lines must be supported, an-chored and guided.

The distance between 2 anchor points forms a movement unit.

The movement between the 2 anchor points may not exceed the permissible value given for one joint.

Depending on the value of axial movement, every second anchor point can be replaced with a guide.

UNI-Coupling pipe couplings do not absorb axial forces. Structural measures for buried pipelines are required in order to absorb axial forces (e.g. lean concrete abutment)

Freely installed pipelines

UNI-Coupling pipe couplings do not absorb axial forces.

Important: Pressure lines must be supported, anchored

and guided. Depending on the installation situation, sup-

ports have to be changed to anchor points.

Guideline: One anchor point and at least one guide point

per pipe section!

Installation of vertical pipelines

Note: The application of UNI-Combigrip and UNI-Plastgrip couplings for installation of vertical pipelines is not recommended.

UNI-Grip pipe couplings are the ideal joints to keep

plain-ended metal pipe sections in vertical installations

perfectly tight and axially restrained.

In the extreme case of a vertical, free-hanging pump

pressure mains, the forces arising for each coupling are

calculated based on the following values:

• weight of pipe sections

• weight of couplings (joints)

• weight of pump

• weight of water column in pipes

• force factor resulting from internal pressure and

possible pressure surges

UNI-Grip, UNI-Combigrip and UNI-Plastgrip pipe couplings

deliver sufficient resistance against torsion, resulting

from switching the pump on or off. (Please consult pump

manufacturer for details.)

Application examples:• drilling hole pump lines

• fresh water pump lines

• heat pumps

• shaft pipelines

• charge and discharge systems of silos,

tanks and containers

Electrical conductivity UNI-Flex/UNI-Rep

UNI-Flex and UNI-Rep pipe couplings do NOT provide electrical conductivity from pipe to pipe.

However, they should not be used as 'insulation'. Even

under prescribed installation conditions, an electrical

contact between the housing of the coupling or the

strip insert and the pipe surface can occur.

If electrical conductivity is required, it can be achieved by

bridging over the coupling from pipe to pipe with an

earth strap.

Should it be necessary to prevent electrical conductivity

of the pipe joint, electrical insulation of the pipeline ele-

ments can be achieved by coupling-in a section of plastic

pipe, measuring one meter in length.

39

Electrical conductivity UNI-Grip

Note: Because of the use of plastic pipes, there is no electrical conductivity with UNI-Combigrip and UNI-Plastgrip pipe couplings.

Electrical conductivity is ensured thanks to the anchoring

rings gripping into the pure metallic surface of the pipe.

UNI-Grip pipe couplings guarantee electrical conductivity for

metal-to-metal piping by bridging over from pipe to pipe

through the metallic anchoring mechanism.

Measurements have proven a sufficiently low electrical

transition resistance of UNI-Grip pipe couplings.
