DN 200 Spiral Steel Pipe,
X52 Spiral Steel Pipe,
DN 200 Spiral Submerged Arc Welded Pipe
API 5L Pipe X60 X65 X70 Dn200- Dn2500 Carbon Spiral Welded SSAW Steel Pipe For Oil And Gas
SSAW steel pipe uses the welding cold expanding process pipe, so the SSAW steel pipe dimension precision, using SSAW steel pipe butt counterparts in good quality so as to ensure the welding quality, through expanding technology to some extent by removing a portion of the internal stress. In addition SSAW steel pipe Welding multiple wire welding (three wire, the four wire ), such that the welding process generated when welding line energy is small, the parent material of heat affected zone of influence degree is small.
Multiple wire welding after welding of former wire can rise to eliminate welding stress effect, thus the mechanical properties of steel pipeThe improvement of. The mother can do by ultrasonic flaw detection of plate 100%, meet the high pressure pipeline of parent material requirements.
