Do You Know About The Corrugated Metal Pipe?

Corrugated metal pipe is composed of stainless steel net body, stainless steel corrugated pipe and various types of joints.  Its inner tube is a thin-walled stainless steel corrugated tube with spiral corrugation or annular corrugation, and the outer mesh sleeve of the corrugated tube is woven by stainless steel wire or stainless steel strip according to certain parameters.  

Corrugated metal pipe has many excellent characteristics, such as good flexibility, fatigue resistance, high and low temperature resistance, corrosion resistance, etc. It has been widely used in aerospace, petrochemical, mine electronics, mechanical shipbuilding, medical and health care, textile electronics, energy construction and other fields.  Especially in curing press, converter, refining machine, continuous casting machine, printing and dyeing machine and other equipment.  With the development of modern industry, corrugated metal hoses resistant to high and low temperature, high pressure and corrosion are more and more widely used.  

It is a new type of pipe with annular outer wall and smooth inner wall. It was first developed in Germany in the early 1980s.  After more than ten years of development and improvement, it has developed from a single variety to a complete product series.  At present, it is very mature in production technology and application technology.  Due to its excellent performance and relatively economic cost, it has been greatly promoted and applied in developed countries such as Europe and the United States.  In our country, the promotion and application of stainless steel bellows is in a rising stage, and all technical indexes have reached the use standard.  It is mainly used for water conveyance, drainage, water supply, exhaust, sewage discharge, subway ventilation, mine ventilation, farmland irrigation, etc.  

The service life of corrugated metal pipe is the shortest working period or cycle number that can ensure normal work when used under working conditions.  The elastic sealing system composed of bellows often works under the condition of bearing variable load and large displacement with more cycles, so it is of great significance to determine the service life of bellows.
