Production of stainless steel seamless pipe

(1) hot extrusion process: hot extrusion process is a foreign hot-working stainless steel seamless pipe of the main production process. Extrusion and rolling (vertical rolling, ramping) production method compared to the extrusion method is characterized by the metal in the deformation process by three-way compressive stress. In this best condition, for the deformation resistance, poor thermoplastic stainless steel pipe can get better internal and external surface quality and microstructure.[url=http://stainlesssteelprices.com/steel-products/7495.html]304 stainless steel street fixed bollard[/url] Due to the improvement of the vertical hydraulic perforation process equipment, the thickness of the wall after the extrusion can reach 5% to 7%. Extrusion machine tool is easy to manufacture and replace, suitable for the production of small quantities, multi-standard stainless steel tube, especially for the production of inclined rolling machine difficult to process high-alloy steel.[url=http://sheetstainlesssteel.com/stainless-steel/5603.html]Supply Stainless steel ASTM TP321 cold finished pipe[/url] (2) hot rolling process: In the country, stainless steel tube perforation commonly used two-roll inclined rolling machine, not only commonly used austenitic stainless steel, including difficult to deformation of duplex stainless steel and high temperature alloys can also be rolled in the two Punching machine on the mass production.[url=http://steelsheetprices.com/steel-sheet/2343.html]high quality z275 prepainted galvalume steel coil[/url] Such as the use of two-roll tapered roller punching machine, can produce steel, capillary surface defects, especially the inner surface defects such as internal fold, less cracks, while the production of capillary wall thickness is thinner, after a variety of rolling (Vertical rolling, skew rolling) can be thinner tube wall, thereby reducing the cold drawn (rolling) pass, productivity and finished product rate is improved, significantly increased economic efficiency.[url=http://steelsheetprices.com/steel-coil/2432.html]GI RHS RECTANGULAR STEEL pipe AND pipes[/url]
