Structure and connection mode of stainless steel corrugated hose
The stainless steel corrugated hose is mainly made of external stainless steel wire mesh and internal corrugated hose. During operation, the external stainless steel wire mesh mainly receives the pressure of the pipeline. The internal stainless steel corrugated hose is mainly used to connect the pipeline and ensure the sealing performance of the pipeline. The external stainless steel wire mesh is mainly made of fine wire mesh or stainless steel ribbon wire mesh, Generally, the stainless steel wire mesh is made of wire mesh with a diameter of about 0.8mm. The stainless steel wire mesh is made of about 1cm wide ribbons. Generally, the wire mesh made of stainless steel ribbons is used in large diameter pipes, and the small diameter pipes are mostly made of fine stainless steel wire mesh. 201 or stainless steel 304 and 316L according to the applied data. The common stainless steel corrugated hose is the combination of 201 external wire mesh and 304 internal corrugated hose, which has the best cost performance.
The stainless steel corrugated hose can be divided into flange type stainless steel corrugated hose, looper flange type stainless steel hose and screw thread type stainless steel corrugated hose according to the connection mode. The stainless steel corrugated hose flange connection is suitable for the connection of large diameter low pressure pipes, and the looper flange type stainless steel corrugated hose is suitable for the connection of long interval stainless steel corrugated hose, The biggest characteristic of the stainless steel corrugated hose with looper flange is that it can adjust the length of the pipe. The flange can rotate well in the pipe and cooperate with the flange device in the pipe to ensure the tightness of the pipe connection. The biggest characteristic of the looper flange connection is that the device length of the pipe can be adjusted at will. Screw thread type stainless steel corrugated hose is mainly high pressure small diameter pipe, which is commonly used in the oil pipeline of some machine tools or the cooling oil pipeline of large machinery, and has good pressure resistance and corrosion resistance characteristics. The screw thread is usually made of stainless steel or copper, and the connection is tight without leakage.
From the structure and connection mode explained above, it can be seen that stainless steel corrugated hose is indeed better than stainless steel corrugated compensator in some aspects, and its characteristics in some environments are more conducive to the characteristics of stainless steel corrugated compensator.
