High frequency straight seam welded pipe equipment is used to produce specified welded steel pipe. It feeds a certain specification steel strip into the machinery and coil it into pipe blank through forming roller .Then under skin effect and proximity effect of high frequency electric current, the current will be concentrated on the bond surface of the pipe fringe, then with help of squeezing/pressing rollers pressure, the pipe blank will be welded into tube quickly .After coiling, sizing and straightening, the needed pipe will be produced. There are roller type, FFX type and rows roller type of machinery unit which can produce kinds of steel pipes including API coupling pipe of grade X80, X100, J55, that comply with API-5L, API-5CT standards.
