Longitudinal Submerged Arc Welding LSAW Steel Pipes Processes
Longitudinal submerged arc welding is a special welding technology used in pipe production. Because of high internal or external pressure, the final product needs high wall thickness. Considering this, the main applications of pipeline LSAW Steel Pipe include oil, natural gas, natural gas, central heating, water supply, sewage treatment and other similar applications. Steel pipe […]
S355J0H vs S355J2H steel pipes
S355J2H and S355J2H steel pipes are both under the European standard en10025-2. S355 steel can be supplied according to Jr, J0, J2 and K2 (mainly with different impact energy requirements), of which S355J2H steel pipes requires -20 ° impact value. S refers to structural steel 355 is the minimum yield strength J2 is impact temperature […]
Seamless pipe and tube and the manufacturing process
seamless pipe and tube and the manufacturing process introduce seamless pipe and Tube The main seamless tube manufacturing process appeared at the end of the 19th century. With the expiration of patents and ownership, the various parallel development that were initially pursued became less and less obvious, and their respective formation stages were merged into […]
manufacturing process of Welded pipe and tube
manufacturing process of Welded pipe and tube Since it is possible to make strips and plates, people have been trying to bend materials and connect their edges to make pipes. This led to the development of the oldest welding process, forging welding, which dates back 150 years. In 1825, James Whitehouse, a British ironmonger, was […]
What is Nominal Pipe Size
Nominal pipe size What is the nominal pipe size? Nominal pipe size (NPS) is the standard size for a set of high pressure or low pressure and high temperature pipes in North America. NPs names are based on an earlier “iron pipe size” (IPS) system. The IPS system was established to specify pipe sizes. Dimensions […]
seamless pipe oil and gas
Seamless steel tubes are produced from billets, which are heated and perforated to form tubular parts. The word “seamless” means no seams. seamless pipe oil and gas are used in different applications in the oil and gas industry: Upstream operation (OCTG pipeline) Midstream (transfer and distribution of fluids, such as oil, gas, steam, acid, slurry) […]
Definition and details of pipes
Definition and details of pipes What is the pipe? The tube is a hollow tube with a circular cross-section, which is used for transporting products. Products include fluids, gases, particles, powders, etc. Unlike pipes, the term “pipe” is used for size tubular products that are commonly used in pipes and piping systems. On this website, […]
