Chinese Professional Rubber Expansion Joint - Stainless Steel Rubber Bellows Expansion Joints Rubber Connector EPDM – Xinqi Detail:

Product Description

Rubber expansion joints are also called rubber joints, flexible rubber joints, flexible rubber compensator, shock absorbers, rubber shock absorbers, etc. The product consists of a tubular rubber part composed of inner and outer rubber layers, cord fabric layers and wire rims, which is vulcanized at high temperature and high pressure and then combined with a metal flange or a loose sleeve of a parallel joint. It can reduce vibration and noise by virtue of high elasticity, high air permeability, medium resistance, weather resistance and radiation resistance of rubber, and can compensate for thermal expansion and cold contraction caused by temperature change. It is widely used in various pipeline systems.

Characteristic:

It has high internal density, can withstand high pressure, and has good elastic deformation effect.

Advantage:

Reduce vibration, noise and lightness.

Purpose:

Connection with pumps, valves and fire-fighting equipment, pipes with large vibration, and pipes with frequent changes in cold and heat.

Applicable media:

Seawater, fresh water, cold and hot water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, product oil, air, gas, steam and granular powder.

Connection mode:

Generally, loose flange type (semi seal), fixed flange type (full seal), clamp type and threaded connection are available.

Material of rubber flexible joint:

The rubber flexible joint ball is composed of a rubber tube with multiple layers of rubber scraped nylon cord fabric and outer rubber layer in the inner rubber layer and reinforcement layer. The rubber materials used are different according to different media, including natural rubber, styrene butadiene rubber, butyl rubber, nitrile rubber, ethylene propylene diene monomer, neoprene rubber, silicone rubber, fluorine rubber, etc. It has the functions of heat resistance, acid resistance, alkali resistance, corrosion resistance, abrasion resistance, oil resistance, etc.

The specific classifications of rubber flexible joints are: Negative pressure resistant rubber joint, acid and alkali resistant rubber joint, oil resistant rubber joint, high temperature resistant rubber joint, wear-resistant rubber head.

Installation of rubber flexible joint:

Rubber expansion joints are widely used in water heating and installation of natural ventilation pipes, water supply and drainage and circulating water pipes, refrigeration pipes, anti-corrosion pipes, fire fighting and refrigeration compressor pipes, as well as in laboratories, scientific research institutions, ships, ships and other pipeline engineering projects to reduce vibration and noise, offset and other maintenance and management methods. The pipe shall be stably suspended in the air water supply and drainage system on the rubber double ball joint on the support, support or anchor frame.

The main characteristics of EPDM rubber expansion joint 

1. Aging resistance: EPDM rubber joint has excellent weather resistance, ozone resistance, heat resistance, acid and alkali resistance, water vapor resistance, color stability, electrical performance, oil filling and room temperature fluidity.

2. High temperature resistance: EPDM rubber joint can be used for a long time at 120 ℃, and can be used briefly or intermittently at 150 – 200 ℃. It has excellent water vapor resistance and is estimated to be superior to its heat resistance.

3. Corrosion resistance: due to the lack of polarity and low unsaturation of ethylene propylene rubber in EPDM rubber joints, it has good resistance to various polar chemicals such as alcohol, acid, alkali, oxidant, refrigerant, detergent, animal and vegetable oil, ketone and grease.

4. Good elasticity: EPDM rubber joint is more elastic than natural rubber joint.

EPDM rubber soft connection can reach 150h without breaking under the condition of 50 pphm ozone concentration and 30% stretching, with weather resistance (use temperature range – 40 ℃ – 150 ℃) and chemical resistance. After adding flame retardant, it has good flame retardancy and flame retardancy. The product is processed by microwave continuous vulcanization once, with smooth and beautiful surface, more stable performance( and not easy to change.
