Rubber Hose Bendability

Rubber Hose Bendability

Rubber hoses are steel braided hoses. The hose consists of an inner layer, a layer of wire braid and an outer layer. Suitable for conveying hydraulic fluids such as alcohols, fuels, lubricants, emulsions and the like.

Different from the hard tube, (rubber) hose is the biggest characteristic of bending. According to the use of working conditions and performance requirements of the difference between the design of the hose vary widely, the common parameters are size, pressure, weight, length, curvature, chemical durability and so on.

Compared with civilian hoses, rubber hoses are more complex and worse than industrial hoses, and equipment is more demanding on pipelines. Therefore, industrial hoses are designed from design, material selection to production, transportation and even final storage. The norms and standards. Industrial hoses are available in a wider range of sizes, with a wide range of pressure and chemical resistance.

Industrial hoses are used in a wide range of industrial manufacturing and distribution areas, and are widely used in industries such as petroleum, chemical, ship, dock, tanker, agriculture, food, beverage, pharmaceutical and hot and cold water, steam, ventilation, , Hydraulic, medium such as gas, water, fog, mud, sand, iron tablets, and so on. PVC hose health grade plastic hose, plastic hose, plastic bellows, food grade hose, sanitary hose, imported hose) has been widely used in water supply piping systems and gas pipeline system, but the past few years PVC Pipeline system in the field of gas transportation market share is almost zero, the amount of water supply system also has a slight decline.However, PVC hose in the non-pressure pipeline system such as drainage, sewage and waste disposal system in the amount of steady growth, Mainly because the production of PVC raw materials on the dependence of crude oil as other thermoplastics, so that the production cost is relatively low.

Plastic bellows, imported hose) can be used solid wall or structural wall of a variety of design, the main connection using solvent bonding. According to whether the use of plasticizers, can be divided into hard polyvinyl chloride (corrosion resistance and high temperature performance is relatively high, while the cost is relatively high.

Although the PE piping system does not have a cost advantage (relatively high raw material prices), it has been rapidly promoted and popularized. This is mainly due to the rapid and convenient PE hose connection, that is, hot-melt connection. Teflon hoses are determined by the melting temperature range and melt viscosity characteristics of PE hoses (sanitary plastic hoses, plastic hoses, polyethylene hoses, food grade hoses, sanitary hoses, inlet hoses) The PE hose has excellent weldability, so that the strength of the PE hot melt connection joint meets or exceeds the strength of the hose body. In addition, the use of PE fused pipe fittings can also make PE pipe system repair work easier, thus improving the safety and reliability of the pipeline.

PP hose (sanitary plastic hose, plastic hose, polypropylene hose, food grade hose, sanitary hose, imported hose) from the 20th century, 70 began to apply to the production of the pipeline. PP material can be divided into three categories: PP-H (homopolypropylene), silicone hose PP-B (block copolymer polypropylene) and PP-R (random copolymer polypropylene) according to the different structure of the polymer.
