Welded pipe is made by cold forming flat strip, sheet or plates into a round or circular shape by a roller or plate bending machine. The pipe is then welded with or without filler material using a high energy source. Welded pipes can be produced in large sizes without any size restriction. ASTM A134 EFW Steel Pipes - Piping & PipelineSep 13, 2019 · The ASTM A134 EFW steel pipe refers to electric-fusion-(arc)welded straight seam or spiral seam steel pipe NPS 16 and over in diameter, with wall thicknesses up to 3/4 (19.00 mm), inclusive. Pipe having other dimensions may be furnished provided such pipe complies with all other requirements of ASTM A134/ A134M.
Welded Pipe. Welded pipe comes in three forms:welded on the outside diameter, welded on the inside diameter or welded on both sides. The commonality is that they all have a seam! Manufacturing and applications:The manufacturing process of welded pipe starts by rolling out a steel coil to the desired thickness to form a flat strip or plate LSAW Steel Pipe, DSAW Steel Pipe, Welded Steel PipeTypes Standard SY/T5040-2000 SY/T5037-2000 SY/T9711.1-1977 ASTM A252 AWWA C200-97 API 5L PSL1 Tube end OD deviation LSAW Steel Pipe, Longitudinally Submerged Arc Welding PipeThe two edges of the open seam pipe are brought together by the tack welding machine. then welded by the tack welder using a metal active - gas arc welding ("MAG")process.
