Detailed Product Description: | The spiral of commonly used standard is generally divided into: SY/T5037-2000 (Ministry of standard, also known as ordinary fluid pipes with spiral submerged arc welded spiral steel pipe), GB/T9711.1-1997 (GB, also known as the oil and gas industry conveyor Spiral Pipe Technical delivery conditions first part: A grade spiral steel pipe (to demanding a GB/T9711.2 B-level spiral steel pipe)), API-5L (American Petroleum Institute, also called pipeline spiral steel pipe; Which is divided into PSL1 and PSL2 two levels), the SY/T5040-92 (pile with spiral submerged arc welded spiral steel pipe) spiral pipe material: Q235A, Q23b, 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9 0Cr18Ni11Nb. Q345 L245 L290 X42 X46 of X70 X80 X95 characteristics: Longitudinal production process is simple, high efficiency, low cost, and rapid development. The strength of the spiral welded pipe is generally higher than longitudinally welded pipes, can narrow the billet production of large diameter welded pipe, billet production of different diameters of the same width of the welded pipe can also be used. However, compared with the same length as the straight seam pipe, the increase in length of the weld 30 to 100%, and a lower production speed. Therefore, most of the smaller caliber welded pipe straight seam welded, spiral welded large diameter pipe they use. Large diameter spiral pipe - Hebei Tianhui Spiral Steel Pipe Co., Ltd. specializing in the production of diameter 159mm-2420mm Wall thickness 4mm-25mm between spiral steel pipe, steel grade product features can be customized to produce a variety of super large diameter spiral steel pipe, especially small-caliber spiral steel pipe, the thin spiral steel pipe, thick-walled spiral steel pipe, spiral steel pipe of special materials, special length spiral steel pipe. And on behalf of clients processing spiral pipe coating, spiral steel pipe insulation, galvanized spiral steel pipe business. The products by ISO9001-2000 national quality system certification Click consultation www.hbthgg.com www.naimoguanjian.com www.thgangguan.com www.hbbgc.com www.pvdfgc.com www.naimogd.com www.hbbengguan.com |
