Product Description

The construction preparation before the use of the straight jointed steel pipe. In order to excavate the pipe trench and finish the pipe shaft masonry, the straight jointed steel pipe needs to be installed, including the electric welding machine, cutting machine, electric hammer and polishing machine.

As the professional manufacture, we would like to provide you Pengfa Longitudinal Welded Pipe for Ground Pile. Straight steel pipe English (Straightsteel pipe), general welded pipe: general welded pipe is used to transport low-pressure fluid. Made of Q195, Q215A, Q235A steel, Q235B plain carbon. It can also be manufactured together with easy-to-weld 0317 standard model 6012 and steel mother 755 mild steel. Steel pipes are subject to water pressure, bending, flattening and other tests, and have certain requirements for surface quality. Usually, the delivery length is 4-10m, and it is often required to deliver in fixed length (or double length).

The specification of the Longitudinal Welded Pipe for Ground Pile is indicated by the nominal diameter (mm or inch). The nominal diameter is different from the actual one. The welded pipe has two types of ordinary steel pipe and thickened steel pipe according to the specified wall thickness. The welding process of submerged arc welding straight seam steel pipe is submerged arc welding technology, which uses filler welding and particle protection flux submerged arc. The diameter of production can reach 1500mm. LSAW is the English abbreviation of submerged arc welding straight seam steel pipe. The production technology of submerged arc welding straight seam steel pipe includes JCOE forming technology and rolling forming submerged arc welding technology.

When the diameter is large, two steel plates may be used for rolling, which will form a phenomenon of double welds. Standards that can be implemented are GB/T3091-2008 low-pressure fluid steel pipe production standards, GB/T9711.1-2-1997 oil and gas steel pipe production and use standards, and American Longitudinal Welded Pipe for Ground Pile execution standards. Production material: Q195A-Q345E; 245R; Q345QA-D; L245-L485; X42-X70. The pressure parameters mainly include 2ST/T, S is the yield strength, and T is the wall thickness. Submerged arc welding has been developed into two-wire submerged arc welding and multi-wire submerged arc welding, and the efficiency is further improved.
