Pipeline Mild Steel Pipe

Pipeline mild steel pipe is put out oil, steam, water, pipeline through the pipeline to oil and gas industry enterprise. Line pipe including seamless pipe and welded steel pipe, the pipe end with flat end, with threaded end and socket end; Its connection way as the end of welding, coupling connection, socket connection, etc.

High grade pipeline steel pipe heat treatment process

With the development of the pipeline steel plate technology and the progress of welded pipe forming, welding technology, the application range of the pipe with welded pipe in gradually expanding, especially in the large diameter welded pipe class scope the advantage of more wet, and cost factors, welded steel pipehas been dominant in the field of line pipe, which limits the development of stainless steel seamless steel line pipe. About 2004 t 2004 seamless line pipe production, steel grade including X42-70, varieties have a seabed pipeline onshore pipeline steel pipe and steel pipe.

Of high grade pipeline steel production is currently a micro alloying heat treatment process, the production cost of stainless steel seamless tube was obviously higher than that of welded pipe, and with the improvement of steel grade, such as the above X80 grade pipeline carbon steel pipe for the limitation of carbon equivalent, seamless steel tube of conventional technology is difficult to meet user requirements; Now every 12 cr1mov alloy pipe factory in for the improvement of line pipe corrosion resistance, the use of stable performance and low temperature, high temperature environment to carry out the scientific research work.

Pipeline mild steel pipe weight calculation formula: [] - wall thickness (diameter) * wall thickness * = 0.02466 kg/m (weight of per meter)
