The circular metal corrugated pipe is introduced
Circular metal corrugated pipe has high integration degree of the structure is simple, high precision, high reliability and strong anti-interference ability and good appearance of small size, etc. Good plasticity for metal corrugated pipe forming processing, and can get enough by subsequent treatment process of hardness and strength.
Circular metal corrugated pipe according to the nominal menstruation, preparation of specifications on a total of 30 DN200 ~ DN1000, shan bo, double wave, according to the form of points and three wave (30). Circular single-wave sealed bellows specifications for compiling DN400 ~ DN1400 a total of 12 kinds.
　Circular metal corrugated pipe is mainly used for high, medium and low temperature hot air pipeline and high frequency mechanical vibration of pipeline, flexibility is good, has the good corrosion resistance, high temperature resistance and shock absorption, absorption of the pipe axial, lateral displacement.
General pressure piping must use the round metal corrugated pipe, round metal corrugated pipe can prevent explosion hazards caused by pipeline capacity is too high, bellows expansion joints have the effect of two pipe drawing, pipeline pressure, slip joint automatic inflation, sometimes called the expansion joint, on the contrary, the pipeline pressure is too small, slip joint automatic retraction, pipeline balance protection role.
