Product Details: Brand V.H. Polymers Thread Size Rubber Flange /SS Flange / MS Flange / Backing Flange / Swivel Flange / Fix Flange Size 2 inch, 3 inch, Upto 72" Application Structure Pipe, Gas Pipe, Hydraulic Pipe, Chemical Fertilizer Pipe, Pneumatic Connections Key Specifications/Special Features: Rubber joints are also called rubber pipe soft joints, flexible rubber joints, rubber soft joints, flexible rubber joints, high-pressure rubber joints, rubber shock absorbers, compensators and so on. According to the structure, it can be divided into single sphere, double sphere, different diameter, curved sphere and air pressure coil. The tubular rubber part is composed of inner and outer rubber, cord layer and traveller, which is vulcanized and then combined with metal flange or parallel joint loose sleeve. This product can reduce vibration and noise, and can compensate the thermal expansion and cold contraction caused by temperature change. It is widely used in various pipeline systems. Rubber joints can also be called flexible rubber joints, rubber soft joints, soft joints, flexible rubber joints, rubber expansion joints, shock absorbers, etc., is a high elasticity, high air tightness, medium resistance and weather resistance pipeline joints. Rubber joints are usually composed of inner rubber layer, fabric reinforced layer (reinforced layer has multi-layer scraped nylon cord fabric), middle rubber layer, outer rubber layer, end-strengthened metal ring or traveller. After vulcanization at high temperature and high pressure, the rubber pipe is loosely combined with metal flange or parallel joint. This product makes use of the advantages of rubber, such as high elasticity, high gas resistance, medium resistance, weatherability and radiation resistance, can reduce the vibration and noise of pipeline, and can compensate the expansion and contraction caused by temperature changes. According to the media used in different rubber materials are also different, there are natural rubber, styrene-butadiene rubber, butyl rubber, nitrile rubber, EPDM, chloroprene rubber, silicone rubber, fluororubber and so on. They are heat-resistant, acid resistant, alkali resistant, corrosion resistant, wear resistant and oil resistant. 1. according to the performance, it can be divided into three categories: general, special and heat resistant. General Class: Suitable for transporting water with temperature ranging from - 15 80 C, acid solution or alkali solution with concentration below 10%. Species: Suitable for special performance requirements, such as oil resistance, plug resistance, ozone resistance, wear resistance or chemical corrosion resistance. Heat resistant: suitable for conveying water at temperatures above 80 degrees centigrade. 2. according to the form of structure, it can be divided into single sphere, double sphere, three sphere, elbow sphere, and wind pressure disc body. Each form can be divided into three categories: concentric equal diameter, concentric diameter and eccentric diameter. 3. according to the shape, it is divided into: Concentric diameter, concentric diameter and eccentric diameter.
