High frequency straight seam welded pipe can be divided into straight seam high frequency resistance welded steel pipe and straight seam high frequency induction welded steel pipe according to different high frequency welding process. The forming process generally adopts roll bending cold forming. The high-frequency straight seam welded pipe is generally produced with a small diameter, and the outer What are steel pipes?What are steel pipes?Steel pipes are long, hollow tubes that are used mainly to convey products from one location to another. They are produced mainly by two distinct manufacturing methods which result in either a welded pipe or seamless pipe. In both the manufacturing methods, raw steel is first cast into a more workable starting form (hot billet or flat strip).Introduction to Welded Pipe Manufacturing - The Process Piping What is Spiral welding?What is Spiral welding?In Spiral Submerged Arc Welding (SSAW) Process, also known as HSAW pipe, welding line shape like a helix. It is using the same welding technology of Submerged Arc Welding with LSAW pipe. Only major difference being SSAW pipe is spiral welded whereas the LSAW is longitudinally welded.Introduction to Welded Pipe Manufacturing - The Process Piping

Overview of ERW/HFW Pipes. ERW pipe is the acronym for electrical resistance welded steel pipe, and HFW pipe represents high-frequency welding (HFW) steel pipe & tube. The pipes are made from steel coil and the weld seam runs parallel to the pipe. And it is one of the most versatile tools in agriculture, industry, and construction activities.HG32 High-Frequency Welded Carbon Steel Tube Mil bright cold rolled high frequency welded steel pipeMATERIAL:Cast Steel, Cr12, 42CrMo COLOR Teneng Blue I. Summary The mill is intended for manufacturing of round pipe of 12mm-32mm with thickness of 0.8mm2.0mm from cold-rolled and hot-rolled coil strip by means of unclosed tubular blank with its subsequent welding into tube, edge heating by means of solid state high-frequency welder, longitudinal seam welding in rolls of tube welding bright cold rolled high frequency welded steel pipeHigh Frequency Straight Welded Pipe Production Line,ERW bright cold rolled high frequency welded steel pipeZhongtai is China ERW pipe making machine manufacturer.

If you are manufacturing or needing welded pipes for use in metallurgy, construction, transportation, machinery
Our high frequency welded stainless steel pipe products are fully certified and manufactured from high quality raw materials and supplied with EN 10204 3.1 certification. Our manufacturing process for high frequency welded stainless steel pipes includes an adequate heat treatment and the examination of chemical and mechanical properties.High frequency welded pipe production processIt is similar to ordinary resistance welding, but there are many important differences.High-frequency welding for carbon steel pipe production has been 40 years of history. High-frequency welding has a large power supply, the different materials, caliber and wall thickness of the steel pipe can achieve a higher welding speed (higher than the maximum welding speed of welding more than l0 times).Images of Bright Cold Rolled High Frequency Welded Steel Pi imagesPeople also askHow is welded pipe manufactured?How is welded pipe manufactured?In this article we will discuss the various methods involved in welded pipe manufacturing. In Electric Resistance Welding (ERW) process, pipe is manufactured by cold-forming a flat sheet of steel into a cylindrical shape.Introduction to Welded Pipe Manufacturing - The Process Piping

The bright cold rolled high frequency welded steel pipeWelded Pipe Manufacturer Engineering ZoneThe process of manufacturing welded pipes starts from rolling flat sheet metals to the desired thickness. These get rolled out of steel coils, and the method used to create welded pipes is known as Electric Resistance Weld (ERW).. The cold-forming method is useful to shape the pipes into rounded tubes. These tubes are then passed through several forming rollers to get a longitudinal shape.Welded Standard & Line Pipe US Steel Tubular ProductsU. S. Steel Tubular Products high frequency electric weld (ERW) line pipe and standard electric resistance weld pipe products are smoothly finished and thin-walled. They are produced by continuously forming coiled hot rolled strip into a tube and welding the longitudinal seam using high-frequency electric resistance welding.
