You can rest assured that you can buy customized Pengfa API 5L Spiral Welded Steel Pipe from us. With many years of production experience, our quality is far ahead of the industry, but we still strive to improve the quality and delivery time to ensure that our customers will receive high-quality API 5L Spiral Welded Steel Pipe. API 5L Spiral Welded Steel Pipes are commonly used in the transportation of oil, gas, and water, as well as in construction and engineering projects. These pipes are available in different grades, sizes, and thicknesses, depending on the specific requirements of the application.
As a professional manufacturer, we would like to offer you Pengfa API 5L Spiral Welded Steel Pipe. Regarding straight steel pipe (Straightsteel pipe), general welded pipe is commonly used for transporting low-pressure fluids. It is made of Q195, Q215A, Q235A steel, and Q235B plain carbon steel. It can also be produced alongside easy-to-weld 0317 standard model 6012 and steel grade 755 mild steel. Steel pipes are subject to tests such as water pressure, bending, and flattening, and have certain requirements for surface quality. Generally, the delivery length ranges from 4 to 10 meters, and it is often required to be delivered in fixed lengths (or double lengths).
The specification of the API 5L Spiral Welded Steel Pipe is indicated by the nominal diameter (mm or inch), which differs from the actual diameter. The API 5L Spiral Welded Steel Pipe comes in two types: ordinary steel pipe and thickened steel pipe, based on the specified wall thickness. The welding process of submerged arc welding straight seam steel pipe utilizes submerged arc welding technology, which employs filler welding and particle protective flux submerged arc. The production diameter can reach 1500mm. LSAW is the English abbreviation for submerged arc welding straight seam steel pipe, and its production techniques include JCOE forming technology and rolling forming submerged arc welding technology.
When the diameter is large, two steel plates may be used for rolling, resulting in a phenomenon of double welds. Standards that can be implemented include 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 API 5L Straight Seam Steel Pipe execution standards. Production materials include: Q195A-Q345E; 245R; Q345QA-D; L245-L485; X42-X70. The pressure parameters mainly comprise 2ST/T, where S represents the yield strength, and T represents the wall thickness. Submerged arc welding has evolved into two-wire submerged arc welding and multi-wire submerged arc welding, further enhancing its efficiency.
