Our ASTM A312 TP304 Welded Pipe inventory is available in random lengths or cut to specific lengths to meet your exact requirements. Over the years, we have gained unique experience with pipes for different applications. We control the manufacturing process from raw material to finished product, with a constant focus on quality to meet demanding specifications.
Welded Pipes are of two types ERW and EFW. A process for producing welded pipe is Electric Resistance Welding (ERW) also known as Contact Welding. Processing of Electric Fusion Welding, also called Continuous Welding begins as coiled steel with appropriate thickness, width and weight is made. SS 304/304L Welded Pipes are available in a wide range of sizes and properties. Due to the weld seam, lower operating pressures are stated in accordance with ASME compared to seamless pipes. In general Stainless Steel welded pipe possess tighter dimensional tolerances than seamless pipes and are less costly if produced in same quantities. Stainless Steel Welded Pipe sizes range from 1/8" to 48" inches and the thickness of the pipes are as follows: Sch 5, Sch 5s, Sch 10, Sch 10s, Sch 20, Sch 30, Sch 40s, Sch 40, Sch STD, Sch 60, Sch 80s, Sch 100, Sch 120, Sch XS, Sch XXS, Sch 160. The Stainless Steel pipe is manufactured and finished according to dimension standards such as ANSI B36.10 and ANSI B36.19.

Properties of 304/304L alloy
304/304L Cold Forming
Type 304/304L is readily formed and fabricated through a full range of cold working operations. It can be used in heading, drawing, bending, and upsetting. Any cold working operations will increase the strength and hardness of the material, and may leave it slightly magnetic.
304/304L Hot Forming
Type 304/304L can be forged in the 1700-2200°F range. For maximum corrosion resistance, forgings should be annealed at 1900°F minimum and water quenched or rapidly cooled by other means after hot working operations.
Type 304/304L is a tough austenitic stainless steel subject to work hardening during deformation and, unless modified for improved machining response, is resistant to chip breaking. The best machining results are achieved with slower speeds, heavier feeds, excellent lubrication, sharp tooling, and powerful, rigid equipment.
Type 304/304L is readily welded by a full range of conventional welding procedures (except oxyacetylene). AWS E308L/ER308L filler metals should be used with Type 304/304L steel, but the molybdenum-containing austenitic stainless steel filler metals may also be considered.
304/304L Heat Treatment
Annealing: Type 304/304L should be heated to 1900ºF minimum and water quenched or rapidly cooled by other means.
Hardening: Type 304/304L cannot be hardened by heat treatment. However, Type 304/304L can be hardened by cold working.
