MAIN TECHNICAL FEATURES:Working pressure up to 2 MPa, the bending radius of pipeline up to ten diameters, working vacuum up to 0.09 MPa. The maximum length of per sec-tion is 10.0 m.

PIPELINE CLASSIFICATION:Pressure pipeline, pressure-suction pipeline, suc-tion pipeline.

PIPELINE CAN BE OPERATED In the temperature range from -50° C to +80° C in operating environment: process water, acid and alkali diluted solutions, abrasive compound.

PIPELINES ARE MANUFACTURED AS FOLLOWSOnshore and offshore options, of various float de-signs depending on environment.

PRODUCT LIFETIME is ensured by wear-resistant inner layer, the com-pounds of which is depending on operating envi-ronment.

RUBBER COMPOUNDSare manufactured in-house using high quality raw materials with highly controlled manufacturing process&

Pipelines produced by our company have a life-time as much as 5 times longer and the weight as much as 2-2.5 times less compared to steel pipelines.

Use Composit’s pipelines is much more advanta-geous compared to steel ones since economic and process benefits may be achived, i.e.:

• buoyancy, flexibility, lack of ball connections (ensures reduced hydraulic losses up to 20 percent);

• easy to mount and dismantle that enables to make use of pipeline in small rivers and offshore areas;

• applied as part of floating dredge ship enables to reduce energy intensity of the hydrotrans-port up to 15 percent and operating costs;

• less vibration resulting from delivery pumps, compensation of heat, linear and temperature expansion;

• reduced costs of routine maintenance due to the improved wear-resistance of the inner working layer.

COMPOSIT RUBBER PIPELINE

FOR MARINE CONDITIONS

FLOATINg RUBBER PIPELINE COMPOSIT IS AN ESSENTIAL PART OF THE HyDRO TRANSPORT SySTEM USINg IN MARINE CONDITIONS.

This type of pipeline is used to transport the abrasive slurry. Wear-resistant rubber compounds are used in the construction of pipeline for long life. Foamed material under the protective layer provides buoyancy.

FOR UNDERWATER DREDgINg PUMP

FLExIBLE RUBBER PIPELINE COMPOSIT FOR THE UNDERWATER DREDgINg PUMP IS USED FOR SOIL DEEP HOISTINg.

SPECIFICATIONFor dredgers with underwater dredging pump the pipelines with reduced bending radius are needed. Using extra-flexible pipelines COMPOSIT enables to make soil hoisting during the working time of the dredger easier. The construction of the pipe-line COMPOSIT enables to bottom and buoy up the dredge head systematically. The sections of the extra-flexible pipeline are produced of the wear-resistant rubber; the length of the pipeline is up to 10 m. Depending on the service conditions the above is used with plastic or whole floats. The size of the inner wear-resistant layer

is calculated individually depending on the compound and the working pressure. In design and production of the wear-resistant rubber pipelines for underwater dredging pumps COM-POSIT special materials that make it extra-flexible are used.

PRESSURE RUBBER PIPELINE

FLExIBLE PRESSURE PIPELINES COMPOSIT ARE USED TO TRANSPORT ABRASIvE COMPOUNDS.

SPECIFICATIONPipelines COMPOSIT are produced of wear-resistant materials with the diameter 102-920 mm and the standard section length - 10 meters. The inner rubber layer can be produced of natural or synthetic rubber depending on the operation terms. Cord fabric carcass provides durability and a uniform distribution of internal loads, while carrying wire frame made of steel helps to do the same in hard operation conditions.

FLEXIBLE INSERTIONS

IN SUBSTITUTION OF THE BALL jOINTS OF THE PIPELINE

FLExIBLE INSERTIONS ARE USED INSTEAD OF BALL jOINTS OF THE PIPELINES. THIS IS A MODERN SOLUTION OF THE PROBLEM WITH CONNECTION OF THE PIPELINES. THIS ITEM IS SUCCESSFULLy USED AS AN ELASTIC INSERTION BETWEEN THE METALLIC PIPELINES TO ASSURE THE REqUIRED TURNINg ANgLE OF THE PIPELINE PARTS. THE BENDINg RADIUS OF THE FLExIBLE INSERTIONS IS CALCULATED ACCORDINg TO THE TERMS OF OPERATION AND THE SPECIFIC CHARACTER OF THE WORk

SPECIFICATIONFlexible rubber insertions are made of wear-resistant rubber, the inner diam-eter is from 159 mm to 820 mm, the secured bending radius of the pipeline is 12 degrees to the both sides of the axis. To obtain the required turning angle the length of the flexible insertions is calculated individually depending on the terms of use.

The advantages of the rubber pipe bends above the steel ones, which assure economical and technologi-cal benefit:

• abrasive wear resistance is 3-5 times better;

• reducing costs of maintenance due to outstanding durability of the inner working layer.

The mounting of the rubber pipe bends requires only bolts; no other special tools are needed.

RUBBER COMPENSATORS

RUBBER COMPENSATORS ARE USED TO CONNECT THE STEEL SECTIONS OF THE PIPELINE

RUBBER COMPENSATORS ARE DESIgNED:• to compensate pipeline temperature expansion;

• to neutralize misalignment in pipe systems due to mounting works;

• to isolate vibration of running machinery and transported medium flows;

• to protect sensitive components and units from forces generated by the running pipeline;

• quench stresses in the metal, as well as in pipe supports;

• sealing pipes of various types;

• to produce flexible insertions of various types.

Range of rubber compensators diameters covers 102 to 920 mm with a wide range of length available depending on the terms of operations. Rubber compensators are made of dura-ble wear-resistant rubber. It provides for additional resistance to exposure of abrasive hydraulic compounds and steady pres-

sure resistance over long time. To decrease the load due to the pressure difference the construction is ensured by equipping arms with reinforcing elements.

The mounting of the rubber compensators requires only bolts; no other special tools are needed.

RUBBER-LINED STEEL ITEMS

RUBBER-LINED STEEL ITEMS ARE USED AS A PART OF THE PIPELINE TO TRANSPORT SLURRy AND ABRASIvE COMPOUNDS USINg HyDRO TRANSPORT DELIvERy. THEy ARE DESIgNED AS A PIPELINE PART TO COMBINE THE FLOWS OF THE SUBSTANCES BEINg RELOCATED

RUBBER-LINED STEEL COLLECTOR

SPECIFICATIONRubber-lined steel items are used in such working environments as technical envi-ronment with a concentration of the oil products up to 20%, acid and alkali solutions. The main advantage of rubber-lined steel items is that the power load is carried by the steel frame of the collector, and the inner rubber tube manufactured of the durable rubber ensures a long-term usage of the product.

The features of the rubber-lined steel items which assure economical and techno-logical benefit above the steel ones are:

• Abrasive wear-resistance is 3-5 times better

• Reducing costs of maintenance due to outstanding durability of the inner work-ing layer.

The mounting of the rubber collectors requires only bolts; no other special tools are needed.

CONNECTION TyPES OF PIPELINES

qUICk COUPLINg IS AN ELEMENT OF THE PIPELINES’ CONNECTION SySTEM WHICH ENABLES TO MOUNT AND DISCONNECT THE SECTIONS OF THE PIPELINE qUICkLy.

Quick coupling consists of two rubber-lined steel sections, thus it is possible to use it together with pipelines to transfer abrasive compounds (sand-and-grave compounds, different types of sand). Mounted on the pipelines this item is fixed with a latch mechanism, while guarantees tight connection of the pipeline parts.

The assembly can be carried out both quickly and easily, without requiring any special adapter devices except for the bolts.

Conventional design of flange is considered as a part of the pipeline.

Reinforced flange ensures ease of mounting and tighter connection compared to other flange types.

Flanges to connection with metal pipeline is a good con-nection between the rubber pipelines and the steel ones.

Flange adapter is used to provide a transition between pipes of different diameter and type, as well as the connection with other equipment.

DEPENDINg ON THE OPERATION CONDITIONS REINFORCED FLANgES, CONvENTIONAL DESIgN FLANgES, FLANgE ADAPTER OR FLANgES TO CONNECTION WITH METAL PIPELINE CAN BE USED
