China Pengfa Casing pipe is a hollow steel tube used for underground construction and utility projects to protect utility lines and product pipes from damage due to construction or weather-related damage.These pipes are available in different grades, sizes, and thicknesses, depending on the specific requirements of the application.
As the professional manufacture, we would like to provide you Pengfa Casing Pipe. Casing Pipe is a hollow steel tube used for underground construction and utility projects to protect utility lines and product pipes from damage due to construction or weather-related damage.According to the production method, seamless pipe is divided into hot rolled pipe, cold rolled pipe, cold drawn pipe, extrusion pipe, pipe jacking and so on. 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 Casing Pipe 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. Casing Pipe is mainly used for petroleum geological drilling pipe, petrochemical cracking pipe, boiler furnace pipe, bearing pipe and high-precision structural steel pipe for automobiles, tractors and aviation.The diameter of production can reach 1500mm. LSAW is the English abbreviation of submerged arc welding Casing 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 Casing Pipe execution standards. 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.
