Chemical composition for ASTM A312 TP304 Seamless Welded Stainless Pipe
Materials and Manufacture ASTM A312 TP304 Seamless Welded Stainless Pipe
The pipe shall be manufactured by one of following processes
Seamless pipe shall be made by a process that does not involve welding at any stage of production.
Welded pipe shall be made using an automatic welding process with no addition of filler metal during the welding process.
Heavily cold-worked pipe shall be made by applying cold working of not les than 35% reduction in thickness of both wall and weld to a welded pipe prior to the final anneal.No filler shall be 100% radiographically inspected in accordance with the requirements of ASTM Boiler and Pressure Vessel Code,Section VII,Division 1,lastest revision.
Welded pipe and HCW pipe of NPS 14 and smaller shall have a single longitudinal weld.Welded pipe and HCW pipe of a size larger than NPS 14 shall have a single longitudinal weld or shall be produced by forming and welding two longitudinal sections of flat stock when approved by the purchaser.All weld tests,examinations,inspections,or treatments shall be performed on each weld seam.
At the option of the manufacturer,pipe shall be either hot finished or cold finished.
The pipe shall be free of scale and contaminating exogenous iron particles.Pickling,blast ing,or surface finishing is not mandatory when pipe is bright annealed.The purchaser is permitted to require that a passivating treatment be applied to the finished pipe.
Heat Treatment-All pipe shall be furnished in the heat -treated condition in accordance with the requirements of Table2.Alternatively,for seamless pipe,immediately following hot forming while the temperature,pipes may be individually quenched in water or rapidly cooled by other means.
