Important Factors Affect Cost Of Steel Pipe and Tube - PDF document

Important Factors aFFect ost teel pe and ube There are a lot of factors that affect price of stainless steel pipe and tube, as majorstructural steel plate suppliers , they try to They think there are some major decisive factors toMonel 400 Pipe, Hastelloy C276 Pipeandtube, manufacturing technology, material have As they know, steel consist of different chemical elements, improve these alloys to form steel, these important elements contain Silicon, In between these alloys, they have to refer to the content of Nickel, after study, they can see price of stainless steel is related with the price of Nickel, Nickel is acostly element.You can check price of stainless steel and Nickel trend, before making any type of decision.Price of stainless steel is up and down with the price of Nickel in the market on the entire trend, innormal condition, price of steel lay behind the price of Nickel price.Steel has different types of grades, mainly considered in Ferritic steels, Austenitic steels, duplex steels and Martensitic steels, different types of grades have different compositionof chemical, thus there are different price, people should select proper grade of stainless as per to applications.Technology of Pipe and Tube ManufacturingSeamless and welded pipe and tube are two producing procedures by manufacturing technology, they are very much different, makers should compute the cost throughout manufacturing process, possibly every manufacture have different types of cost, higher cost requires to greater technology to improve price competitiveness.Price of Welded Tube & PipeWelded pipe and tube start from plate or strip, welding two edges by advanced technology to form concluding products, there are some methods of welding to opt, costs are very much different, list of main welding methods are as following:ERWTIGHFWERWThese famous types are different costs, together with cost of equipment, cost of material and cost of energy, they affect complete cost in the price of pipe and tube, and result in different quality of welding, users must specify concern method of welding if neePrice of Seamless Pipe and TubeSeamless pipe and tube start from billet, in assessment with welded pipe and tube, seamless pipe and tube producing procedure is difficult, major process contain cold rolling,cold drawing, heat treated as well as pickling, some procedure need to be repeated that result in more cost, seamless pipe and tube use off line incinerator for heat treatment that generates more cost too.
