Distinguish hot-rolled steel pipe,welded steel pipe and cold-formed steel pipe from the appearance. Hot-rolled steel pipe:It is relative to cold rolling, cold rolling is rolling below the recrystallization temperature, and hot rolling is rolling above the recrystallization temperature. Welded steel pipe:refers to a steel pipe with seams on the surface that is welded into a round or square shape with steel strips or steel ERW Steel Pipes:ERW steel pipesERW steel pipes and tube are available in various qualities, wall thicknesses, and diameters of the finished pipes. ERW pipes means Electric Resistance Welded Pipes. A plate rolled to become a pipe and welded using Electric Resistance Welding process. Usully for for high
ERW steel pipe/tube making machine. ERW steel pipe/tube making machine, the process is unwinding the steel coil and make the head and tail of the coil butt-welded in the strips preparation section.Then the strips fed into accumulator and pulled out of the accumulator at a constant speed passed through the unit. Next, the strip is formed into an open tube in the forming unit. High Frequency Induction (HFI) Welded Pipe - Sunny SteelIn 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. HIGH-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

How to Weld Steel Pipe?Steel plate or steel pipe is used in the blanks of welded steel. We can use electric arc welded pipe, high or !ow frequency electric resistance welded pipe, gas pipe, stove pipe, Bundy tubes according to different methods. Here we talk about how to welded steel pipe. First dean the weld oil, paint, water, rust, etc., and then according to the
ERW welded steel pipe:High frequency electric resistance welded pipe, raw material is hot rolled steel plate, through the continuous forming, bending, welding, heat treatment, sizing, straightening, cutting process.. Feature:Compared with SSAW steel pipe, it has advantages of high dimensional accuracy, uniform wall thickness, good surface quality, high pressure resistant performance, etc. Introduction to Welded Pipe Manufacturing - The Process
- Electric Resistance Welding (ERW) ProcessSubmerged Arc Welding (Saw) ProcessElectric Flash Welding ProcessLap Welding ProcessSquare&rectangular Welded Steel Pipes And Tubes Square tube is a hollow square section of light thin-walled steel tube, also known as steel cold bending section. It is a type of square section shape steel made of Q235 hot rolled or cold rolled strip or rolled plate for the cold bending of the parent material after cold bending and then high frequency welding.

Seamless pipe is divided into the hot-rolled seamless pipe and cold drawn seamless pipe,hot-rolled seamless pipe is producing through the billet forging, punching, rolling, shaping, and other processes.
Manufactured via cold forming, and high frequency electric-resistance welding (ERW) with various sizes, and thickness that comply with major International, and Malaysia standards. The mild steel black welded steel pipe (black pipe) is commonly used in furniture, Welded vs. seamless steel pipe American Piping ProductsWelded pipe manufacturing techniques have improved over the years. Perhaps the most important advancement has been the switch to high-frequency electric currents for welding. Prior to the 1970s, low-frequency current was used. Weld seams produced from low-frequency ERW were more prone to corrosion and seam failure.
