GNEE supplies welded pipe, per ASTM A 312, ASTM A 358 or as rolled and welded. We supply common grades of stainless such as 304/304L and 316/316L in standard pipe sizes and schedules including Sch 5, Sch 10, Sch 40s and Sch 80s.
We also supply more challenging stainless welded pipe requirements including 304H, 316H, 309/S, 310/S, 317/L, 321/H, 347/H, 410, 410S, Duplex 2205, Duplex 2507 and many other grades of stainless, duplex or nickel alloys.
We can even supply material with wall thicknesses up to 3″ thick! Diameters sizes range from 1/8″ up to 96″. We specialize in the quick delivery of non-standard welded pipe. We recently supplied a steel mill with 3 pieces of 11-1/2″ OD x .625″ Wall x 13' Type 316/316L and delivered the product in 5 days to meet a shut-down requirement. All welded pipe products can be cut to size. Specialty testing, including X-ray, Hydro Testing and more can be supplied upon request.
