Difference Between Erw And Efw Steel Pipes Hebei Haihao Group

Difference Between Erw And Efw Steel Pipes Hebei Haihao Group Difference between erw and efw steel pipes. erw steel pipe is the abbreviation of resistance welding. the welding methods of erw pipe and submerged arc welded pipe are obviously different. pressure welding without filler metal is adopted. the skin effect and proximity effect of high frequency current are applied to the edge of instantaneous. Efw steel pipe (electric fusion welding steel pipe) refers to an electron beam welding, the use of high speed movement of the electron beam directed impact kinetic energy is converted to heat the work piece so that the work piece leaving the melt, the formation of the weld. efw steel pipe is formed by rolling plate and welding the seam.

Difference Between Erw And Efw Steel Pipes Hebei Haihao Group Efw (electric fusion welding) refers to an electron beam welding, the use of high speed movement of the electron beam directed impact kinetic energy is converted to heat the work piece so that the work piece leaving the melt, the formation of the weld. applications of efw steel pipe. if you want to know more technical information,please contact. Efw pipe manufacturing process. in efw welding process, the external high energy electric arc is used to create a weld joint. once the welding is done, the excess weld material from outside and inside of the pipe is removed with the help of trimmer tools. in general, to reduce the negative effect of welding, a localized heat treatment of weld. Erw pipe are formed by continues rolling method. in this method, a flat metal strip from the strip coil is feed into the series of roller assembled in line. these rollers gradually form the strip in the circular section. at the end of rolling assembly, this pipe is continuously welded by welding machine. specifications of erw steel pipes:. The main difference between erw and efw pipe is the welding process used. erw pipe is made with a resistance welding process that creates a robust and reliable seam. efw pipe is made with an electrode fusion welding process that creates an even stronger seam. both types of pipe are resistant to leaks and corrosion, but efw pipe can handle.

Erw Pipe Vs Efw Pipe What S The Difference Erw pipe are formed by continues rolling method. in this method, a flat metal strip from the strip coil is feed into the series of roller assembled in line. these rollers gradually form the strip in the circular section. at the end of rolling assembly, this pipe is continuously welded by welding machine. specifications of erw steel pipes:.

The main difference is the frequency of welding current. the meaning of hfw pipe is high frequency welded pipe. hfw pipe manufacturing uses a high frequency current (usually above 70 khz). the high frequency help to faster the manufacturing process as well as give high weld quality compared to erw pipe manufacturing. Established in 1982, hebei haihao high pressure flange & pipe fitting group co., ltd.covers an area of 78,000 square meters with the building area of 55,000 square meters. we have fixed assets of 30 million yuan. situated in industrial area of mengcun county, the home of elbow and pipe fitting of china, with cangzhou port in theeast and beijing.
