ASTM A381 / A381M - 18 Standard Specification for Metal

1.1 This specification covers straight seam, double-submerged-arc-welded carbon or high-strength low-alloy steel pipe (Note 1) suitable for high-pressure service, 16 in. [400 mm] and larger in outside diameter, with wall thicknesses from 5 / 16 to 1 1 / 2 in. [8 to 40 mm]. ASTM A381 / A381M - 18 Standard Specification for Metal 1.1 This specification covers straight seam, double-submerged-arc-welded carbon or high-strength low-alloy steel pipe (Note 1) suitable for high-pressure service, 16 in. [400 mm] and larger in outside diameter, with wall thicknesses from 5 / 16 to 1 1 / 2 in. [8 to 40 mm]. The pipe is intended for fabrication of fittings and accessories for compressor or pump-station piping.

Defect Analysis of High-precision Cold-rolled Seamless

Nov 20, 2020 · The submerged arc welded straight seam steel pipe is also called the double-sided submerged arc welded straight seam steel pipe or LSAW straight seam steel pipe, where LSAW is (Longitudinally Submerged Arc Welding abbreviated as LSAW). Resistance welded straight seam steel pipe is also called ERW straight seam steel pipe. Defect Analysis of High-precision Cold-rolled Seamless Nov 20, 2020 · The submerged arc welded straight seam steel pipe is also called the double-sided submerged arc welded straight seam steel pipe or LSAW straight seam steel pipe, where LSAW is (Longitudinally Submerged Arc Welding abbreviated as LSAW). Resistance welded straight seam steel pipe is also called ERW straight seam steel pipe. Difference between Double-sided Submerged Arc Welded Double-sided submerged arc welding straight seam steel pipe uses, the first advantage is fully automated; the second advantage, it is under the submerged arc welding, so its heat exchange and protection performance is relatively strong, welding out The quality is relatively high; The third advantage, because the submerged arc welding in the arc buried in the bottom of the welding, so it can use high

Double Submerged Arc Welded (DSAW) Steel Pipe -

Double Submerged Arc Welded (DSAW) steel pipe is available in straight and spiral welded formats and used in a variety of applications. The submerged welding process protects the steel from contamination of impurities in the air. Both inside and outside welds are performed.

Line Pipe - EVRAZ North America

Straight Seam and Spiral Line Pipe. Produced at EVRAZ Regina, Portland and Camrose, double-submerged arc welded (DSAW) large diameter straight seam and spiral pipe for oil and gas transmission is available with external fusion bonded epoxy and abrasion-resistant overlay coatings, as well as internal epoxy coating. Pipe Manufacturing Process / Methods for Seamless & Welded SAW- Submerged Arc Welding (Long seam & Spiral Seam) ERW Steel Pipe Manufacturing Process In the ERW / EFW / HFW pipe process, the first plate is formed in a cylindrical shape and the longitudinal edges of the cylinder formed are welded by flash-welding, low-frequency resistance-welding, high-frequency induction welding, or high-frequency Pipe Manufacturing Process / Methods for Seamless & Welded SAW- Submerged Arc Welding (Long seam & Spiral Seam) ERW Steel Pipe Manufacturing Process In the ERW / EFW / HFW pipe process, the first plate is formed in a cylindrical shape and the longitudinal edges of the cylinder formed are welded by flash-welding, low-frequency resistance-welding, high-frequency induction welding, or high-frequency

Straight seam steel pipe welding process - The Children's

Jul 26, 2019 · External welding:welding by longitudinal multi-wire submerged arc welding on the outside of straight seam submerged arc welded steel pipe; Ultrasonic inspection I:100% inspection of the inner and outer welds of straight seam welded steel pipes and the base metal on both sides of the weld; Submerged Arc Welding - an overview ScienceDirect TopicsJan 09, 1993 · Klas Weman, in Welding Processes Handbook (Second Edition), 2012. Power sources. Power sources for submerged arc welding may have either straight or drooping characteristics. A straight characteristic provides good self-regulation of the arc length. The wire feed speed is sometimes also controlled by sensing the arc voltage and adjusting the wire feed speed to maintain a constant arc What is the difference between straight seam steel pipe Welded steel pipes with only one longitudinal weld are straight welded steel pipes. According to the regulations of GB/9711.1, the diameter of the straight-welded steel pipe is greater than 914.4, and the welding angle is 180°. The straight-sealed steel pipe can be the same twice.
