ASTM A335 Seamless Pipe, is a kind of seamless steel tube, its performance is much higher than the general seamless steel tube, because this kind of steel tube contains more Cr, its high temperature resistance, low temperature resistance, corrosion resistance is less than other seamless steel tube, so alloy tube is widely used in petroleum, chemical, electric power, boiler and other industries

ASTM A335 Seamless Pipe, Elements include silicon, manganese, chromium, nickel, molybdenum, tungsten, vanadium, titanium, niobium, zirconium, cobalt, aluminum, copper, boron, rare earth and so on.

ASTM A335 Seamless Pipe, A long strip of steel with a hollow section and no seams around it. The steel pipe has a hollow section and is widely used for conveying fluid pipelines, such as conveying oil, natural gas, gas, water and some solid materials. Alloy seamless steel pipe and round steel and other solid steel, in flexural and torsional strength at the same time, the weight is lighter, is a kind of economic section steel, widely used in the manufacture of structural parts and mechanical parts, such as oil transportation, stair handrails, bicycle frame and construction of steel scaffolding. Making ring parts with alloy seamless steel pipe can improve material utilization rate, simplify manufacturing process, save material and processing time, such as rolling bearing ring, jack sleeve, etc., has been widely used in steel pipe manufacturing. Alloy seamless steel pipe or all kinds of conventional weapons indispensable material, barrel, barrel and so on to steel pipe to manufacture. In addition, the annular section under internal or external radial pressure, the force is more uniform, therefore, the vast majority of alloy seamless steel tubes are round

ASTM A335 Seamless Pipe, The Production Process

Hot rolling (extruded seamless steel tube) : round tube billet → heating → perforation → three-roll cross rolling, continuous rolling or extrusion → tube stripping → sizing (or reducing) → cooling → blank tube → straightening → water pressure test (or defect detection) → marking → storage.

Cold drawing (rolling) seamless steel tube: round tube billet → heating → perforation → heading → annealing → pickling → oiling (copper plating) → multi-pass cold drawing (cold rolling) → blank tube → heat treatment → straightening → water pressure test (flaw detection) → marking → storage
