BLACK PIPE CLASS AA ( 6 METER )

FEATURES: 

• Longitudinal welded pipe has simple production process, high production efficiency, low cost and rapid development.
• The strength of spiral welded pipes is generally higher than that of straight seam welded pipes. A narrower blank can be used to produce welded pipes with larger pipe diameters, and a billet with the same width can also be used to produce welded pipes with different pipe diameters.
• But compared with the straight seam pipe of the same length, the weld length is increased by 30-100%, and the production speed is lower.
