Shanghai katalor enterprises co.,ltd Is the ASTM A714 grade I low alloy steel pipe/tube manufacturer,we have Machining equipment for steel pipe deep processing, we focus on seamless steel pipe(Line pipe,Pipe for structures,Boiler Pipe,Pipe for conveyance of fluid), Welded steel pipe (general welded circular tube,square tube,Rectangular tube).if you need ASTM A714 grade I low alloy steel pipe/tube,contact us! ASTM A714 grade I specification covers seamless and welded high strength low-alloy steel pipe NPS1⁄2to NPS 26, inclusive. ASTM A714 grade I material is intended for pressure piping service, and other general purposes, where savings in weight or added durability are important. These high-strength low-alloy steels have enhanced resistance to general atmospheric corrosion by weathering as commonly encountered in rural, urban, marine, and industrial environments.
