ASTM A312 304 Stainless Steel Welded Pipe / ERW SS Pipe DN10 - DN500 in 6m Length
Our Products 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.

BEVELING
Beveling Stainless Steel tubes contain one end angled, so that it mates with a complementary tube end. Tubes can be beveled for certain applications in order to make welding of stainless steel tubes easier, which saves weld prep time and money compared to hand cutting.
HEAT TREATING & ANNEALING
Penn Stainless Products can heat treat some 400 series stainless steel seamless tube. Heat treating realizes stress as a result of hardening, depending upon the chemistry of the metal being treated. Heat treating is also used for tempering, quenching, normalizing, and solution annealing.
HONING & TURNING
During the honing/turning process, an abrasive rotating tool removes metal from the interior surface of a cylinder, pipe, or tube. The main purpose of honing is to finish the surface to a particular diameter and/or desired cylindrical geometric design. Honing is typically a secondary machining operation that completes a produce/part, relieves stress created during production, or corrects features of the finished product. A typical production cycle is to drill, ream, heat treat, then hone.
POLISHING
POSITIVE MATERIAL IDENTIFICATION (PMI)
In some cases, it may be necessary to complete additional positive material identification testing. Penn Stainless Products can complete this testing in house or we can work with an independent laboratory to complete the testing. Please contact us for specific requirements.
UT TESTING
Ultrasonic Testing (UT) utilizes sound energy at high frequencies, in order to provide examinations and measurements of the stainless steel product. This aids in flaw detection/evaluation, dimensional measurements, etc.
