Designation And Structure Of Large Diameter Silicone Rubber Cold Shrink Tube

- Nov 20, 2019-

A type of tubular rubber product used to convey gas, liquid, slurry or granular materials. Large diameter silicone rubber pipe is composed of inner and outer rubber layers and skeleton layers. The materials of skeleton layer can be cotton fiber, various synthetic fibers, carbon fiber or asbestos, steel wire, etc. Natural rubber, styrene butadiene rubber or cis-1,4-polybutadiene rubber are used as the inner and outer rubber layer of general large-diameter silicone rubber pipes; chloroprene rubber and nitrile rubber are used as the oil-resistant large-diameter silicone rubber pipes; ethylene propylene rubber, fluororubber or silicone rubber are used as the acid and alkali resistant and high-temperature resistant large-diameter silicone rubber pipes.

There are many kinds of large-diameter silicone rubber pipes named. The unified naming method is named for different materials, structures and uses. The full name of the product is: materials + structures (processes) + uses + large-diameter silicone rubber pipes. For example: Cotton braided oil resistant large-diameter silicone rubber pipe; steel wire wound pressure resistant large-diameter silicone rubber pipe.

The structure of large-diameter silicone rubber pipe is usually divided into inner rubber layer, outer rubber layer and skeleton layer (or middle layer). The inner rubber layer directly bears the wear and erosion of the transmission medium; the outer rubber layer protects the inner body of large-diameter silicone rubber pipe from the damage and erosion of the external environment; the skeleton layer is the pressure bearing layer of large-diameter silicone rubber pipe, which gives the strength and rigidity to the pipe body. The working pressure of large-diameter silicone rubber pipe depends on the material and structure of the skeleton layer.
