Product Details

          Large diameter spiral steel pipe is a general term, generally refers to the diameter of more than 1 meter spiral steel pipe.The commonly used materials of large-diameter spiral steel pipe in China are:Q235A, q235b.q23b, 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb, Q345, L245, L290, X42, X46, X70, X80. 

          Spiral steel pipe is made by bending and welding steel strip.Steel pipe to carry out water pressure, bending, flattening and other experiments, there are certain requirements on the surface quality, usually delivery length is 12 meters, often require the size of delivery.The specification of spiral steel pipe is expressed by the nominal diameter (mm), the nominal diameter is different from the actual, there are two kinds of ordinary steel pipe and thickened steel pipe according to the regulation.

         Spiral steel pipe is mainly used in water engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, urban construction, is one of the twenty key products developed in China.For liquid transport: water supply and drainage.Gas transportation: gas, steam, liquefied petroleum gas.For structure: for pile driving pipe, as a bridge;Wharf, road, building structure pipe, etc.

          Spiral steel pipe is welded by submerged arc welding.Forming process, front pendulum intermittent production;Unit speed, 0.5--3m/min;Welding speed, 0.5--3m/min.The unit consists of uncoiling machine, straightening machine, centering device, hydraulic shear, milling welding machine, disc shear, milling edge machine, plate surface cleaning equipment, delivery machine, plate edge pre-bending equipment, molding machine, internal welding, external welding, flash, dialing, slag dumping, filling welding, flat head chamfering, water pressure inspection, finished product inspection, except oil collection.
