Straight seam steel pipe production line with high frequency straight seam steel pipe ERW production line,Guest Posting SAWL double-sided submerged arc welding steel pipeproduction line, the COW combination welding straight seam steel pipe production line, SAWL double seam welding straight seam steel pipe production line, 12 meters straight seam welded steel production line.

1, straight seam steel pipe production line is given priority to with high frequency straight seam steel pipe ERW production line, high production efficiency, low cost and 60% of the world's steel tube product use the high frequency straight seam welded steel pipe production line.

2, SAWL double-sided submerged arc straight seam steel pipe production line is mainly products of thick wall or big diameter, and in a variety of customized specified length, mainly production orders, don't do mass production inventory. SAWL straight seam welded steel pipe production line is the biggest characteristic of flexible production specifications, not restricted by outer diameter size, can produce 325 mm - 1420 mm in diameter, 6-80 - mm wall thickness of any specifications.

3, use fewer COW combination welding assembly line products. Double seam steel pipe production line is consistent with the principle of SAWL straight seam steel pipe production line, the difference is that the double seam welded steel pipe production equipment minimum diameter of 914 mm.

4, 12 meters straight seam welding line, the pressure for the coining and by the three-roll rolling forming of a rolled straight seam straight seam steel pipe.

SAWL, rolling straight seam steel pipe production technology and standard production line

SAWL straight seam production process:

Production process: steel plate ultrasonic testing - the width of steel plate for pre cut - V groove - JCOE steel weld end cold stamping molding, straight seam semi-finished CO2 pre - straight seam welded steel tubes inside and outside weld seam submerged arc welding, straight seam steel pipe weld industrial television online detection, outside weld removal, straight seam steel pipe straightening roundness correction, welding seam X-ray tube end his mouth - hydrostatic test - tube body coating - marking into the Treasury.

Rolling straight seam steel pipe production process:

Steel plate ultrasonic testing - width of steel plate for pre - cutting steel V groove weld end - mill roll to molding - rolling straight seam steel pipe buried inside seam welding, seam to remove - both inside and outside coil pipe bender fine alignment round, nondestructive flaw detection, port handling, water pressure test, marking into the Treasury.
