You should be able to clearly explain your needs to the supplier when buy food grade discharge and suction hose, so Orientflex, a one-stop supplier can recommend suitable food grade hose to you!
The food grade discharge and suction hose is a utility model including food grade hose. The metal pipe has an inner and outer layer. The inner layer pipe, namely the bellows, is made of stainless steel, which is divided into 201,201 P, 921,933,934. Wire rods made of carbon steel and stainless steel. Theoretically speaking, the raw material of carbon steel is simply corroded, but the working pressure is not too different from that of stainless steel raw material.
These two materials are stainless steel bellows, woven outside a layer or multiple layers of steel mesh sleeve, the two ends are connected together or flange head, used for conveying various media elastic elements.
Main application: conveying corrosive chemical medium. Such as: ammonia handling, etc.; Transport of high temperature gas, hot oil of high temperature medium, etc. (e.g., hot steam, thermal conductivity oil, etc.); Low or ultra-low temperature transport medium. (e.g., liquid nitrogen). Transporting water, steam, oil and other media in high temperature environment. (e.g. water vapor system and hydraulic system of coke, steelmaking, continuous casting equipment); Piping used to reduce vibration or noise. (e.g., export and import pumps);
The main difference between the two is the raw material of the outer wire weaving layer. Wire rods made of carbon steel and stainless steel. The simple corrosion of carbon steel raw materials is also relatively cheap.
