Material and structure of low temperature resistant hose

Low temperature hose overviewLow-temperature hose means that the hose itself can normally transport the fluid medium in a low-temperature environment. It means that the outer rubber layer of the hose is not frozen and cracked in a low temperature environment, and the rubber layer in the hose can transport ultra-low temperature fluid media such as hydraulic oil and petroleum-based oils.Low temperature resistant hose materialThe low temperature resistance of rubber hoses is mainly due to the use of special rubber rubber raw materials in the hose production process, as well as the addition of rubber cold resistant chemical raw materials. The production of this special composite rubber raw material requires a high production process.Low temperature hose classificationLow temperature hose according to the specific application field is divided into, low temperature hydraulic hose, low temperature industrial hose (suction and drainage hose, exhaust hose, oil pipe and many other industrial hose products)Low temperature resistant hose structureThis kind of hose has a three-layer structure of inner rubber layer, outer rubber layer and middle skeleton layer. The middle layer can have a variety of reinforcement layer types, such as steel wire layer, fiber layer, cotton thread layer (cotton hose usually uses cotton thread layer) and cloth.
