Our stainless Products stocks stainless steel Seamless pipe per ASTM A 312 in 304/304L and 316/316L. We supply other stainless grades, including 304H, 316H, 309/S, 310/S, 317/L, 321/H, 347/H, 904L, 330, 254SMO, 410. In duplex grades, we can supply 2205 and 2507. Some nickel grades are also supplied.
We supply a full range of pipe schedules ranging from Sch 5 thru Double Extra Heavy. Most products are available in 20′ random length sections, but Penn Stainless Products can supply stainless steel seamless pipe in most stainless grades in sections exceeding 40′. All stainless steel seamless pipes can be cut to your exact requirements. Some made to order items can be produced in 2-3 weeks.
Our Service
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.
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.
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.
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.
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.
