ASTM A519 SAE1026 Alloy Steel Pipe, OD 180mm, Cold Drawn, for Mechanical Service.

Introduction

Alloy steel pipe is mainly used in power plant, nuclear power plant, high pressure boiler, high temperature superheater and reheater, etc.

Description
Alloy seamless steel pipe (Seamless Steel Tube) with hollow section, no joints around the strip steel. The steel pipe has a hollow section and is widely used as a pipeline for conveying fluid, such as oil, natural gas, gas, water and some solid materials. Compared with solid steel such as round steel, alloy seamless steel pipe is light weight when bending and torsion strength is the same. It is an economic section steel, which is widely used in the manufacture of structural parts and mechanical parts, such as oil conveying, stair handrails, bicycle frames and steel scaffolding used in construction. Making ring parts with alloy seamless steel pipe can improve material utilization, simplify manufacturing process, and save material and processing time, such as rolling bearing ring, Jack sleeve and so on. At present, steel pipe has been widely used to manufacture. Alloy seamless steel pipe or all kinds of conventional weapons indispensable materials, gun barrel, barrel and so on must be made of steel pipe. In addition, the ring section under internal or external radial pressure, the force is more uniform, therefore, most alloy seamless steel pipe is a circular pipe.

Alloy tubes are roughly made of Mn,27SiMn,40Cr,12-42CrMo 16Mn12Cr1MoV,T91:16-50 27SiMn 30CrMo 15CrMo 20G Cr9Mo 10CrMo910 15Mo3 15CrMoV 35CrMoV 45CrMo ,15CrMoG,12CrMoV,45Cr,50Cr,45CrNiMo, etc.

Production process
Hot rolling (extruded seamless steel pipe): pipe billet → heating → perforation → three-roll oblique rolling, continuous rolling or extrusion → pipe → diameter (or diameter reduction) cooling pipe straightening → hydraulic test (or flaw detection) marking → storage.
Cold drawing (rolling) seamless steel pipe: round tube billet → heating → perforation → head → annealing → pickling → oiling (copper plating), multi-pass cold drawing (cold rolling)→ billet tube heat treatment, straightening → water pressure test (flaw detection) marking → storage.
