Manufacturing of 25mm Heavy-Wall Linepipe Using the High hfi welding

Following the successful industrial HFI welding production of 609,6mm (24 ) × 25mm thick wall pipes at the CPW-Thisvi mill, the current paper deals with the development of the process regarding forming, welding, process automation and NDE inspection techniques for thicknesses up to 25mm. The latter made possible the broadening of the HFI hfi weldingManufacturing of 25mm Heavy-Wall Linepipe Using the Keywords: HFI pipe production, micro-alloyed steel, thick gauge pipes, high grade pipes. 2. INTRODUCTION High Frequency Inductive (HFI) welding, a highly productive and consistent industrial welding process, is a commonly used technique in the production of Some results are removed in response to a notice of local law requirement. For more information, please see here.Manufacturing Process for Welded Pipes. How To Produce hfi weldingIn HFW/HFI welding, a high-frequency current is used to create weld joints. Whereas, 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.

High Frequency Induction (HFI) Welded Pipe

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 metal coil with single or multiple windings.High Frequency Induction (HFI) Welded PipeHIGH-FREQUENCY WELDING is a welding process in which the heat source used to melt the joining surfaces is obtained from high-frequency (HF) alternating current (ac) resistance heating. Coil edges are milled using carbide cutters in order to assure a high quality weld.Hfi Welding in Tulsa, OK with Reviews - Page 3 - YP hfi weldingFind 138 listings related to Hfi Welding in Tulsa on YP hfi welding.

Our professional project team allows us to serve as the Prime Contractor on projects requiring detailed planning and phasing.Choosing a welding process for tubular profilesHFI weldings biggest advantage is speed. If a continuous seam is possible and no other factors limit the welding speed, then generally HFI is the right choice, especially if the application calls for high-volume production. The processes are summarized in Figure 9.Boosting efficiency in solid state weldersHigh-frequency induction (HFI) welding is used widely by the tube producing industry, but a large number of variables need to be controlled to perform the operation successfully. In the HFI welding process, high-frequency current is induced in the open seam tube by an induction coil located ahead of (upstream from) the weld point (see Figure 1).
