ERW steel pipe is formed by rolling strip and welding the seam, with tighter dimensional tolerances and less weight. The weld seam Permissible variations for A53 ERW steel pipe Note:1. For exact length (cut length), length tolerance is -0.0mm / +6.0mm, as ASTM A530. 2. The weight (mass) tolerance of unit pipe
Difference between ERW, SSAW, LSAW - Sunny SteelDifference between ERW, SSAW, LSAW. Steel pipe for pipe technology, can be divided into (SML), mainly as the Oilfield internal transportation pipeline and small-diameter high-pressure natural gas pipeline, used for a small number of long-distance gas pipeline, the vast majority of long-distance pipeline with Direct seam high frequency (ERW), spiral submerged arc (SSAW), LSAW three (LSAW).
High frequency welding (HFW) steel pipe is that ERW pipe produced with a welding current frequency equal to or greater than 70 kHZ. Through high-frequency current welding resistance, the heat generated in the contact objects, so the objected surface are heated to the plastic state, then with or without forging to achieve a combination of steels.

Electric Resistance Welded Pipe. ERW (Electrical Resistance Welding) pipes are manufactured by cold forming of steel coil into a round cylindrical shape are used in various engineering purposes. ERW steel pipe is formed by rolling plate and welding the seam.
Metal Pipe - Seamless Pipe - ERW Pipe - Galvanized PipePipes are sold by "nominal pipe size" in sizes from 1/8" to 72". The two most common types of pipes are welded pipe and seamless pipe. Both are available in carbon steel and stainless steel. Welded pipe is also called ERW (Electric Resistance Welded) pipe. Most common specification for welded carbon steel pipe is A53.
Method of Removing Rust for ERW Welded PipeAug 24, 2020 · The surface treatment of ERW welded pipe has an impact on the life of the anti-corrosion layer. Therefore, it should be strictly in accordance with the anti-corrosion layer. Standardize the requirements for the surface of ERW straight seam steel pipes, and continuously improve the surface treatment methods of ERW welded pipes.
