Resistant EPDM NBR Single Double Sphere Rubber Expansion Joint

NBR oil resistant rubber joint is also known as oil resistant shock throat, oil resistant rubber expansion joint, oil resistant soft joint, etc., widely used in automobiles, ships, ships with more oil damage engine room, oil pipeline, hydraulic pipeline and other equipment. Transportable media include hot and cold water, seawater (which can contain oil), various oil and gas wastewater, lubricating oil and grease, air and compressor air containing oil.

Product name: Oil resistant rubber joint, also known as oil resistant shock throat, oil resistant rubber expansion joint, oil resistant soft joint, etc

Product features: oil-resistant rubber joint has good physical and mechanical properties, oil resistance, heat resistance, fire resistance, sunlight resistance, ozone resistance, acid and alkali resistance, chemical reagent resistance. The disadvantage is poor cold resistance and storage stability. It has high tensile strength, elongation, reversible crystallinity and good adhesion. Aging resistance, heat resistance. Excellent resistance to oil and chemical corrosion. Classification: oil penetration rubber joint, nitrile oil resistant rubber joint, oil resistant wire buckle type rubber joint and other specifications.

Product usage: Widely used in automobile, ship, ship oil stains more engine room, oil pipeline, hydraulic pipeline and other equipment. Transportable media include hot and cold water, seawater (which can contain oil), various oil and gas wastewater, lubricating oil and grease, air and compressor air containing oil. Temperature range -25 ° C to 90 ° C Up to 100 ° C for a short period of time.

Oil-resistant rubber joint properties:

1. The product has the characteristics of oil resistance, aging resistance, good elasticity, large compensation amount, easy installation, etc.

2. It can reduce the transmission noise and vibration absorption capacity of the pipeline structure when working. It has irreplaceable use value in heavy industry such as petroleum machinery, aviation, lifting equipment and pipeline.

3. The oil-resistant rubber joint can solve the transverse, axial and angular displacement of the pipeline, and is not limited by the pipe through the heart and the flange is not parallel. When working, it can reduce the transmission noise of pipeline structure and has strong vibration absorption ability.

4. Good flexibility, lined with chloroprene rubber and nitrile rubber two materials. According to the different needs of the pipeline, although chloroprene rubber has poor low temperature resistance, it is very suitable for transporting high temperature oil or gas within 100 ° C. The NBR has strong low temperature resistance and good wear resistance to the crystals formed by water in the low temperature oil pipeline.

5. The high temperature rubber joint will not be deformed in normal use at the rated temperature, nor will it produce harmful odor substances.
