May 23, 2005 · yes, the typical "DOM" is in fact welded, its actually a friction pressure lap weld, there is no type of filler used, the tube is drawn over a spinning mandrel by two other spinning mandrels, the extreme pressure and friction from the spinning roller welds the pipe. true seamless is done by actually shearing a hole thru solid billet material. technically this is also "DOM". i would say find out what the part is used for, then go from there.. i would guess they would have said "seamless" Metal Pipe - Seamless Pipe - ERW Pipe - Galvanized Pipe Welded pipe is also called ERW (Electric Resistance Welded) pipe. Most common specification for welded carbon steel pipe is A53. Seamless pipe is made by a process that requires no welding. Most common specification for seamless carbon steel pipe is A106B.

Tubing is available in a wide array of sizes, materials, lengths, and origins. One of the key factors that must be considered when selecting tubing is the manufacturing process:Seamless or Welded. Seamless Manufacturing Process Seamless tubing is manufactured from a solid billet that has been extruded into a seamless pipe, known as a hollow  Seamless pipe in sizes acc. to ANSI/ASME Sandvik Seamless, stainless steel tubes in sizes according to ISO/EN. For sizes below 13.5 mm (0.53 in.), see our hydraulic and instrumentation tubing program, which also includes a wide range of sizes in duplex and super-duplex stainless steels. Sandvik holds an extensive stock of stainless steel fittings according to ASME, ISO and DIN.

Steel Tubing, Seamless or Welded What is LSAW and HSAW? - Welspun Middle East Pipes LLC In the HSAW type, steel coils are welded spirally, like a helix, so that the coil (strip) assumes the shape of a pipe. SAW pipes are used mainly in oil and gas transportation. On the other hand, seamless (non-welded) pipes are mainly application in oil and gas exploration projects.Cold Drawing Mill Tubing CentralTubing Central 7865 Will Rogers Blvd. Fort Worth, Texas 76140 USA Tel:817-986-0940 Email:[email protected] Web:tubingcentral
