Psl1 Astm A53 Grade B Pipe Water Tranmission Hrdro Power

Psl1 Astm A53 Gr.B Water Tranmission Hrdro Power Project LSAW Steel Pipe

Lsaw steel pipe Is made of JCOE steel pipe forming, a weld, submerged arc welding process, the specification ranges from 325 mm - 1420 mm.When the straight seam submerged arc welding pipe diameter greater than 914.4 standard allows two straight weld steel pipe.Straight seam submerged arc welding pipe products perform low pressure fluid steel tube standard of GB/T3091-2008, GB/T9711.1 oil gas pipeline execution (2) - 1997 standard, ASTM A252 welding structure of steel pipe standards in the United States.

Can implement the standard GB/T3091-2008 low pressure fluid steel pipe production standard, GB/ T9711.1-2-1997 oil and gas steel pipe production and use standard, can also implement the American API 5L pipeline steel pipe implementation standard.Production material: Q195A-Q345E;245 r;Q345QA - D;L245 - L485;X42 - X70.

PSL1 does not require impact performance, PSL2 all except x80 grade steel, full size 0 ℃ average Akv: longitudinal p j, 41 lateral acuity 27 j.Average grade X80 steel, full size 0 ℃ Akv: longitudinal 101 j, or lateral acuity 68 j.3, line pipe should do water pressure test, and the standards are not allowed to nondestructive generation of hydraulic pressure, which is also the API standard and one big difference between our country standard.
