HFI welding - Mannesmann Line Pipe GmbH

Mannesmann Line Pipe uses the high-frequency induction (HFI) resistance pressure welding technique for longitudinal welding. The endless strip passes through rolling stands where it is shaped to an open pipe, which runs through a high-frequency inductor consisting of a High frequency welding effect on steel pipeMar 14, 2018 · Date:2018-03-14 View:1576 Tag:High frequency welding effect on steel pipe In the process of high-frequency welding of steel pipes, the control of the welding process and process parameters, the position of the induction coil and the location of the resistance have a great influence on the welding quality of the steel pipe welding. Welded Steel Pipes for Sales from leading Welded Steel According to different welding methods, it can be divided into arc welded pipe, high frequency or low frequency electric resistance welded pipe, gas welded pipe, furnace welded pipe, Bondi pipe, etc. Meanwhile, according to its steel characteristic and carbon content of steel, welded steel pipe also may be made by mild steel and high carbon steels.

Welding Procedures for Steel Pipes

Class A pipes are generally welded with ordinary carbon steel Q235, Q235F and common low-alloy structural steel 16Mn. Class B pipes are welded with Q235, Q235F, Q195 and other steels, and are used as low-pressure fluid delivery pipes. b. Spiral seam high-frequency welded steel pipe Spiral seam high-frequency welded steel pipe, there is no What is a HFW steel pipe? - ugsteelmillDec 04, 2018 · The high-frequency welding for carbon steel welded pipe production has been 40 years of history. Having a large power supply power, high-frequency welding of different material, diameter and wall thickness of a steel pipe can reach a higher welding speed (highest ratio TIG welding speed is more than l0 times higher). frequency welding steel pipe, frequency welding steel pipe frequency welding steel pipe, Wholesale Various High Quality frequency welding steel pipe Products from Global Sodium Tripolyphosphate Suppliers and frequency welding steel pipe Factory,Importer,Exporter at Okchem.
