It is used in building engineering, construction material, scaffolding, line pipes, underground transfer assemble structural, chemical liquid transfer, oil and gas transfer etc. Outside surface can be treated by galvanized, oil, black painting, 3pe or as customer request.
API 5L X46 PSl2 Pipe, L320 PSL1, X46 PSL2 ERW and Covers Welded, ERW and Seamless pipe used for conveying gas, water, and oil in both the oil and natural gas industries. Hot-Dipped Galvanizing May be ordered galvanized.
ERW steel pipes are manufactured by low-frequency or high-frequency resistance resistance. They are round pipes welded from steel plates with longitudinal welds. ERW pipes are manufactured using steel coils:the coil is first uncoiled, then smoothed, cut, and, finally formed into a pipe shape by joining its two extremities electrically.
Differences of Spiral Pipe and ERW- Know It HereSheet pile manufacturers manufacture ERW and spiral pipe with different manufacturing methods and both are different. See the differences here
Electric Resistance Welded Pipe, ERW Steel Pipes, Electric ERW steel pipes and tubes are used in various engineering purposes, fencing, scaffolding, line pipes etc. The surface condition of steel pipe is known as the environment that this is through the steel pipe coating with the surrounding soil insulation, pipe surface condition is different from the four weeks the soil.
This process is used to manufacture pipes and tubes with lower wall thickness. In ERW, a flat strip of the metal is passed through a series of rollers to mold them in a cylindrical shape. This cylindrical shaped pipe is then welded by passing a high frequency electric stream between the edges and forcing them together to make a bond.
Erw pipe and electric Welded profiles:buy from Metinvest ERW tubes and profiles are mainly used in the construction and housing-and-municipal sectors. Gas and water steel pipes are mainly used for water and gas piping at residential and industrial buildings. Such products are popular because in many regions it is unacceptable to install pipes made of other materials.

Historical perspectives and use cases for welded vs. seamless steel pipe. ERW and seamless steel piping exist as alternatives today largely due to historical perceptions. Generally, welded pipe was considered inherently weaker because it included a weld seam. Seamless pipe lacked this perceived structural flaw and was considered safer.ERW Pipe Electric Resistance WeldedElectric resistance welded (ERW) pipe is made from steel coil and the weld seam runs parallel to the pipe. The width of the coil is the same as the circumference of the pipe so diameters are limited to 24 inches. However, because the manufacturing process is fast, it is ideal for large production runs of small (<= 24 in.) diameter sections.
