ASTM A312 Tp304l Stainless Steel Pipe is one of the most widely used steel pipes in the world for many reasons. The ASTM A312 Gr Tp304l is cheaper than most other stainless steel products and therefore is cost effective. It is an austenitic stainless steel and has chromium content in it. This makes the ASTM A312 Grade Tp304l corrosion resistant. This quality is desired in most applications. The A312 Tp304l Pipe can be produced in different methods and it could come in different shapes as well. Oshwin Overseas is a large manufacturer and supplier of these pipes and we produce all kinds and variations of the product. Our A312 Tp304l Efw pipes are very strong and have long lasting joints because of the electric fusion weld. We also produce electric resistant welded pipes as well.
The applications of ASTM A312 Grade 304l are various. They are seen mostly in the food and beverages industry, cryogenic applications, sanitary and pressure containment applications as well. Because of the low carbon content in the ASME SA312 Type 304l is less strong than the ordinary 304 material. Nevertheless, the 304l Stainless Steel Pipe is widely used for the corrosion resistance. There are different variations such as the 304l Schedule 10 Stainless Steel Pipe which indicates the particular wall thickness to diameter. The 304l Stainless Steel Seamless Pipe and 304l Welded Pipe are used in unique applications according to the needs. We produce 304l Schedule 40 Pipe and other schedules and pressure classes of these pipes. You can get a full product list upon contacting us.
