ERW Pipe
My-steels Group provides high-quality control ERW Steel Pipe in ASTM, API, JIS, GOST, and EN standards with API, JIS CE, and ISO certifications. ERW (Electrical Resistance Welding) pipes are manufactured by cold forming of steel coil into a round cylindrical shape. The Out Diameter is from 1/2"-26". ERW Pipes are usually for Construction, Oil and Gas, Water pipelines, Supply, Piling, and more.
The advantages of ERW pipe:
There are no fusion metals used during the manufacturing process. This means that the pipe is extremely strong and durable.
The weld seam cannot be seen or felt. This is a major difference when looking at the double-submerged arc welding process, which creates an obvious welded bead that might need to be eliminated.
With the advances in high-frequency electric currents for welding, the process is far easier and safer.

ERW Pipe Description
ERW steel pipes are manufactured by low-frequency or high-frequency resistance "resistance". They are round pipes welded from steel plates with longitudinal welds. It is used to transport oil, natural gas and other vapor-liquid objects, and can meet various requirements of high and low pressure. At present, it occupies a pivotal position in the field of transportation pipes in the world.
During ERW pipe welding, heat is generated when current flows through the contact surface of the welding area. It heats the two edges of the steel to the point where one edge can form a bond. At the same time, under the action of the combined pressure, the edges of the tube blank melt and squeeze together.
Typically the maximum outside diameter of ERW tubing is 24", and as a specialty manufacturer, baolai can go up to 26".
For larger sizes the tubes will be made in SAW, feel free to contact us for a quote.
