Before welding, pipe is formed in round shape passing through a series of driven and idler rollers of forming section. In welding section pipe is longitudinally welded by using high frequency induction welding method. Outside bead is removed and formed in shape of scrap. The weld seam is ironed and pipe passes through the cooling section.

It uses to transport vapor and liquid objects such as oil and natural gas. Electric resistance welding (ERW) refers to a group of welding processes such as spot welding and seam welding. faying surfaces where heat to form the weld is born by the
longitudinally welded steel pipes longitudinally high frequency induction welded steel pipes erw/hfi, acording to api 5ct (latest edition), grade j55, High frequency welded (HFW) pipe making machine (ERW High frequency welded (HFW) pipe making machine (ERW HG60 - Teneng Products Made In China, China Manufacturer. HG60 high frequency longitudinally welded pipe production line is used to manufacture welded steel pipes of 20mm-60mm with 0.8mm-3.5mm of wall thickness, which also can produce profiled pipes within the limit of processing round pipes.
If the orientation of the impeller is not good, it will affect the welding speed and welding quality of the welded pipe, causing the crack of the steel pipe. 4) Technical parameters of high-frequency welding - Input heat control high-frequency power input to the pipe weld How is the Welded Steel Pipe Made? - Permanent SteelERW steel pipe:high-frequency straight-slit electric resistance welded pipe, which adopts hot-rolled wide-rolled material as material, through pre-bending, continuous forming, welding, heat treatment, sizing, straightening, cutting and other processes, compared with spiral, it has short weld seam, standard The precision is high, the wall thickness is uniform, the surface quality is
LSAW produce Technology Center . LSAW (Longitudinally Submerged Arc Welded Steel pipes) in leaflets plate as raw material, the steel plate in the mold or molding machine pressure (volume) into using double-sided submerged arc welding and flaring from production. OPTIMISING TECHNOLOGY FOR PRODUCTION OF HIGH HIGH FREQUENCY, WELDING, CONTACTORS, X60 STEEL, PIPES, MICROSTRUCTURE . 1. Introduction Over the past few decades severe demand were placed to the pipes manufacturer with respect to the development and processing of the material for the pipelines. Generally longitudinally welded steel
Izostal S.A. is a wholesale and retail provider of seamless steel pipes of domestic and foreign manufacturers. The pipes are manufactured in line with the following standards:EN 10208-2, EN 10208-1, EN-10216, DIN 1629, DIN1630, DIN 17120, DIN17175, DIN 2391, API Spec 5L, ASTM A53/A106 and PN-80/H-74219. The Advancement and Superiority of Longitudinal Tips:Straight seam steel pipe is a steel pipe whose weld seam is parallel to the longitudinal direction of the steel pipe. Straight seam steel pipes can be divided into high-frequency straight seam steel pipes and submerged arc welded straight seam steel pipes (LSAW) according to the production process. Straight seam welded pipe has simple
High Frequency Induction (HFI) Welded Pipe In High Frequency Induction (HFI) Welded Pipe production process, hot rolled steel coils are fed with a high capacity accumulator in order to achieve continuous welding. LSAW (Longitudinally Submerged Arc Welded Steel pipes) in leaflets plate as raw material, the steel plate in the mold or molding What is a Welded Steel Pipe? About Welded or ERW Steel The defects that occur in spiral welded pipe are mainly those associated with the SAW weld, and are similar in nature to those for longitudinally welded SAW pipe. Electric Resistance Welded (ERW) and High Frequency Induction (HFI) Welded Pipe, originally this type of pipe, which contains a solid phase butt weld, was produced using resistance

Basic principles of high frequency welding. The so-called high frequency is relative to the frequency of the alternating current of 50Hz, and generally refers to the high frequency current of 50KHz~400KHz. When high-frequency current passes
