Stainless Products supplies welded pipe per ASTM A 269, ASTM A 249 or as rolled and welded. We supply common grades of stainless such as 304/304L and 316/316L in standard pipe sizes and wall thicknesses, as well as 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 more.
Product Introduction
We can even supply material with wall thicknesses up to 3″ thick! Diameters sizes range from 1/8″ up to 96″. All welded pipe products can be cut to size. Specialty testing services can also be provided. Stainless pipes can be polished per request and cut to size.

Value-added Services
- Kuncheng cut your next welded tubing requirement to your exact dimension.
- Take advantage of our Domestic and International stainless pipe mills to supply non standard wall thicknesses, lengths or chemistry.
- Tubing can be polished per customer specification; some ID sizes can also be polished.
BEVELING
Beveling Stainless Steel pipes contain one end angled, so that it mates with a complementary pipe end. Pipes can be beveled for certain applications in order to make welding of stainless steel pipes easier, which saves weld prep time and money compared to hand cutting.
HEAT TREATING & ANNEALING
Kuncheng can heat treat some 400 series stainless steel seamless pipe. 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 pipe. 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. Kuncheng 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.
