Rubber-cloth expansion joints

Collective Alliance "Donterrezina i KO"
Rubber-cloth expansion joints are designed to prevent possible gas leakage in the areas of stress of medium and low pressure underground gas pipelines, in areas with increased seismic activity as well as in areas which are exposed to soil movement under pressure from mine workings, landslides, etc.

Compensators are installed at the joints of gas pipes at a distance of 30-100 meters from each other and work on tension, compression and bending in conditions of constant contact with natural gas preventing gusting of gas pipelines.

Main technical characteristics.

- Compensating ability for compression-stretching - up to 150 mm. (counting from the normal unstressed state).
- Working environment - natural gas
- Operating temperature range is from -30 to + 40 ° C.
- Working pressure - 3 kg / cm2
- Type of connection with the pipe - flanged according to GOST 12827


An example of the designation of the compensators "KS-150" where KS is the type of compensator (medium pressure),150 - diameter of the nominal passage, mm.

Types and sizes of produced compensators:

Technical plate TMKCh GOST 7338-90

Collective Alliance "Donterrezina i KO"
It is designed for the manufacturing of rubber products and is used to seal fixed joints to prevent friction between metal surfaces, to perceive single shock loads as well as gaskets, decks and other non-sealing joints.

The width and length of the plate depending on the thickness are made of the following dimensions:
Sheet size up to 1000x1000 mm.
Temperature interval Working area
-45 - +80
-30 - +80
-30 - +80
Air of rooms, vessels: nitrogen; inert gases at a pressure of 0.05 to 0.4 MPa or fresh, marine, industrial, sewage without organic solvents and lubricants: a solution of salts with a concentration up to the saturation limit; acid, alkali concentration of not more than 20% at a pressure of 0.05 to 10.0 MPa.

We produce the Form Plate in the following sizes:

- The size of the plate is 250 * 250 mm. Possible thicknesses in mm: 2; 4; 5; 10
- The size of the plate is 500 * 500 mm. Possible thicknesses in mm: 3; 6; 8; 10; 12; 20; 28; 40; 50

We produce the non-shaped technical plate of the following sizes:

- thickness: from 0.9 mm. up to 12 mm.
- width: 1000 mm.
- length: from 1 m. up to 10 m. (depends on the selected thickness)

Symbol:

The plate 1N-1-ТМКCh-С-3 GOST 7338-90 where

1 - plate class;

H - unformed form;

1-type rubber;

ТМКCh - plate brand;

C - the degree of hardness;

3-thickness (mm.).

Hardness of plates:

M- 35-50 conventional units. ShoreA

С - 50-65 conventional units. ShoreA

T- 65-85 conventional units. ShoreA

They have a wide field of application in many branches of industry (mechanical engineering, fuel and oil industry, etc.), designed to seal stationary joints of mechanisms, to prevent friction between metal surfaces, to damp vibrations and to perceive shock energy in single loads. They are used as gaskets and decks.

Working medium - water, acids, alkalis, air, nitrogen, inert gases. It is effective at temperatures from -45 ° C to + 80 ° C.

During storage rubber products must be protected from direct sunlight, oil, gasoline, kerosene, their vapors, acids, alkalis, gases and other substances that can destroy rubber.
