The biggest difference between ERW pipe and seamless steel pipe is that ERW pipe has welding line, which is the same as welded steel pipe, but seamless black steel pipe doesnt have, either does the welded steel pipe. Furthermore, the welding line of ERW pipe is the key to the quality of ERW steel pipe.A53 Seamless & Welded (ERW) Steel Pipe ASTM A53 ASTM Specification A53 covers seamless and welded, black and hot-dipped galvanized nominal (average) wall pipe for coiling, bending, flanging and other special purposes and is suitable for welding.
Number of Tests Seamless and Electric Resistance Weld (ERW) bending, flattening, tensile on one length of pipe from each lot of 500 lengths, or less, of each pipe size. Permissible Variations for A53 steel pipe. Wall thickness The minimum wall thickness at any point shall not be more than 12.5% under the nominal wall thickness specified.Black Steel Pipe Schedule 40, Black Seamless & Welded erw black welded mild pipeBlack steel pipe is made up of steel that has not being galvanized. Its name comes from the skin, dark-colored iron oxide coating on its surface. It is used in applications that does not requires galvanized steels.

The welded seam of electric weld pipe is heat-treated after welding to a minimum temperature of 1,000°F or processed so that no untempered martensite remains. Such differences of erw are usually eliminated if the electric-weld tubing is heat-treated by the quenched-and-tempered process, which is mandatory for API grades L80, C90, T95, and P110.Difference between Seamless & ERW Stainless Steel pipeHigh frequency Induction Welding Technology is used for ERW Pipes &Tubes upto 21-inchesOD. How to Identify Seamless or ERW Stainless Steel pipes? To identify that a pipe supplied is seamless or ERW, Simply read the stencil on the side of the pipe. If it is ASTM A53, Type S means seamless. Type F is furnace but welded, Type E is Electrical erw black welded mild pipeDifferences between ERW Steel Pipe and HFW Steel PipeHigh 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.
