3. ERW pipe is "high frequency resistance welded steel pipe", which is different from ordinary welded pipe welding process. The weld seam is made by melting the base metal of the steel strip body, and its mechanical strength is better than that of ordinary welded pipe. ERW stands for resistance welding.
Electric Resistance Welded Pipe, ERW Steel Pipes, Electric
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.
ASTM/ASME A53/SA53 Seamless and Welded Standard Steel
U. S. Steel Tubular Products ASTM/ASME A53/SA53 seamless and welded steel pipe is a general, all-purpose pipe used in generator plants, refineries, compressor stations, natural gas transmission, and steam conduction. It is acceptable for welding, flanging, and bending.
Welded Pipe American Piping distributes an extensive selection of welded pipe, including Electric Resistance Welded (ERW) and Double Submerged Arc Welded (DSAW) carbon steel pipe — along with their respective flanges and fittings. We also carry A139 — Grade B, A252 Grades 2 & 3 spiral weld pipe, and A691 chrome moly pipe.
Tycoon Piping conveys a broad choice of sch 40 welded steel pipe material, including Electric Resistance Welded (ERW) and Double Submerged Arc Welded (DSAW) carbon steel pipe — alongside their separate spines and fittings. We additionally convey A139 — Grade B, A252 Grades 2 and 3 winding weld pipe, and A691 chrome moly pipe.
ERW PIPE (ELECTRIC RESISTANCE WELDING) ERW pipes are manufactured using steel coilsthe coil is first uncoiled, then smoothed, cut and, finally formed into a pipe shape by joining its two extremities electrically. ERW pipes are available in sizes between 1/2 and 20 inches, in carbon steel (ASTM A53 is the most common specification) and stainless steel (ASTM A312).
Welded steel pipe is formed by rolling plate and welding the seam. It is cost-effective pipe with tighter Dimensional tolerances and less weight. It is intended for conveying gas, vapor, water or other liquid in low and medium pressure ambient, such as water mains system, sewerage system, Oil and gas pipeline, fire protection service, etc.

Difference between ERW, DOM and Seamless Tube Metal
May 12, 2015 · The nomenclature ERW refers to a specific type of welding process that involves both spot and seam welding. Seam welding is commonly used during the manufacturing of round, square and rectangular steel tubing. The steel strip is unwound from coils and side-trimmed to control width and condition the edges for welding.
ERW steel pipes and tubes are used in various engineering purposes, fencing, scaffolding, line pipes etc. These pipes are highly durable, reliable, corrosion resistant and possess high strength. ERW pipe is available with square ends or beveled for welding, threaded and coupled and victaulic grooved.
ERW/LSAW Welded Steel Pipe - China SHANGH TOP STEEL
1.Straight Seam steel pipe:straight pipe joints are parallel to the longitudinal welds and steel pipe. Usually divided into metric welded steel pipe, welded thin-walled tube, transformer cooling tubing etc.;
Performance and UsageSeamless steel pipe has better pressure capacity, strength is higher than ERW welded steel pipe. So it is widely applied in high pressure equipment, and thermal, boiler industries. Generally the welding seam of the welded steel pipe is the
What is the difference between EFW stainless steel pipes
“ ERW steel pipe ” is a straight seam electric resistance welded pipe, abbreviated as ERW pipe, which is a round pipe welded by steel plates. It is used to transport vapor and liquid objects such as oil and natural gas, and can meet various requirements of high and low pressure.
The pipe is welded first inside and then from the outside. In the case of double seam saw pipe first two halves are joined by tack weld which is called fit-up. Double seam saw pipe is havening a two weld seam opposite to each other. Both the seams are welded from inside and outside of the pipe.

ASTM A252 Pipe Pile Specifications (In seamless & welded
Welded pipe pile referred as ERW (electric resistance welded), LSAW (Longitudinal Arc Sub-merged Welding) and DSAW/SSAW (Spiral Arc Welded Pipe). Chemical composition and Mechanical Properties ASTM A252 allows a limit of phosphorous maximum at 0.050%, This is because P will make steel more fragile and break, further more higher P is not good
