DSAW pipe is typically either pyramid rolled (three angled OD rolls in the shape of a pyramid form the pipe) or rolled using the U-O-E process (skelp is first subject to a "U" shaped press, followed by a "O" shaped press). The most prominent difference between ERW and DSAW carbon steel pipe is the longitudinal weld. Comparison Between ERW and Seamless Steel PipeERW steel pipe:Hot-rolled strip steel is used as the raw material. The thickness tolerance of modern hot-rolled strip steel can be controlled within 0.05mm, and seamless steel pipe is produced by round steel perforation, and the wall thickness deviation is large. Subsequent hot rolling can partially eliminate the wall thickness. Differences Bewteen Seamless Steel Pipe and Welded Steel Seamless steel pipe can be formed one time in the rolling process. Welded steel pipe is manufacturing with steel strip or steel plate, through bending and different welding processes. 3. Performance and Usage. Seamless steel pipe has better pressure capacity, strength is higher than ERW welded steel pipe.
High-frequency straight seam electric-resistance welded steel pipe(erw steel pipe) is hot-rolled coil after forming machine, the use of high-frequency current skin effect and proximity effects, the tube edge heating and melting, squeeze roller under pressure welding to achieve production.High-frequency resistance welding steel pipe, welding pipe and ordinary welding process is not the same Inclusions and Laminations - Rolled Alloys, Inc.A rolled in lap on the surface of the metal, invisible when the product ships, but which opens up upon further work machining or rolling. An imperfection that opens up during bending. 1. Picture of a lamination in alloy. 2. Picture of "severe" lamination from a blister in carbon steel. Standard Specification for Pipe, Steel, Electric-Fusion 1.1 This specification covers electric-fusion (arc)-welded straight seam or spiral seam steel pipe NPS 16 and over in diameter (inside or outside as specified by purchaser), with wall thicknesses up to 3 / 4 in. [19 mm], inclusive. Pipe having other dimensions may be furnished provided such pipe complies with all other requirements of this specification.
