ASTM B619 Welded Pipe Manufacturer

Sachiya Steel International Is One Of The Leading Manufacturer And Exporter Of High Quality ASTM B619 Welded Pipe, which is often used for gas turbine combustion cans and ducting, heat – treating equipment. The outstanding oxidation resistance of our ASTM B619 Hastelloy Pipes is illustrated, where two criteria for evaluating oxidation resistance are weight change and depth of corrosion penetration. Tests were being carried out by exposing samples of our ASTM B619 Nickel Alloy Pipes to dry air at 2000 Degree F and to dry air pressurized to 300 psi at 1750 Degree F. These ASTM B619 UNS N10675 Welded Pipes excels in both respects due to the formation of a protective, tenacious oxide film.

These ASTM B619 Nickel Alloy Welded Pipes as well resists carburization and nitriding, two common conditions which often lead to early failure in high – temperature alloys. After 100 hours in petroleum coke, four other materials were completely penetrated by carburization; whereas, specimens of our ASTM B619 Nickel-Cobalt Pipes showed no carburization at all.

These ASTM B619 Nickel-Cobalt Welded Pipes finds use in petrochemical process equipment and gas turbines in the hot combustor zone sections. Also our ASTM B619 Nickel-Cobalt Alloy Pipes is used for structural components in industrial furnace applications because of the excellent oxidation resistance. These ASTM B619 Nickel-Cobalt Alloy Welded Pipes is recommended especially for use in furnace applications for the reason that it has unusual resistance to oxidizing, reducing, and neutral atmospheres.

Scope And Manufacturing

 

ASTM B619 specification covers welded pipe of nickel and nickel-cobalt alloys (UNS N10001; UNS N10242; UNS N10665; UNS N12160; UNS N10624; UNS N10629; UNS N10675; UNS N10276; UNS N06455; UNS N06007; UNS N06975; UNS N08230; UNS 06002; UNS N06022; UNS N06035; UNS N06058; UNS N06059; UNS N06200; UNS N06985; UNS N06030; UNS R30556; UNS N08031; UNS N06230; UNS N06686; UNS N06210; and UNS R20033). Two classes of pipe are covered as Class I which is as welded and solution annealed or welded and sized and solution annealed; and Class II which is welded, cold worked, and solution annealed. All pipes shall be furnished in the solution annealed and descaled condition. The pipe shall be made from flat-rolled alloy by an automatic welding process with no addition of filler metal.

Subsequent to welding and prior to final heat treatment, Class II pipes shall be cold worked either in both weld and base metal or in weld metal only. The material shall conform to the composition limits set by this specification. Tensile strength, yield strength and elongation of the material shall conform to the mechanical requirements. Tension test, flattening test, transverse guided bend test, and hydrostatic or nondestructive electric test shall be performed.
