Stainless Steel 321 Pipe Fittings

Stainless Steel 321 Pipe Fittings

A403 wp321 material is titanium stabilized austenitic stainless steel which provides good corrosion resistance. It has excellent resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range of 427– 816°C. Stainless Steel 321 Pipe Fittings are available in plumbing systems for different functions and purposes. Itis used in plumbing system to join multiple pipes of same size or different sizes, to regulate the flow or to measure the flow. 321 stainless steel fitting alloy resists oxidation to 1500°F and has higher creep and stress rupture properties than alloys 304 and 304L. It also provides good low temperature toughness. 321 stainless elbows are installed between two lengths of pipe to allow a change of direction. Usually 90° or 45° elbows are available, a 90º elbow is also known as a "90 bend", "90 ell" or "quarter bend" and a 45° elbow is also known as a "45 bend" or "45 ell". Elbows are also categorized by length. The radius of curvature of a long-radius elbow is 1.5 times the pipe diameter, but a short-radius elbow has a radius equal to the pipe diameter. astm a403 wp321 pipe fittings cannot be hardened by heat treatment, only by cold working. By standard shop fabrication practices it can be easily welded and processed.a403 gr wp321 Tee is a type of pipe fitting which is T-shaped which has two outlets at 90 Deg to the connection to the main line. It is a short piece of pipe with a lateral outlet. Pipe tees are widely used pipe fittings. a403 wp321h reducer is useful in power plants and chemical factories. It makes the piping system reliable and compact. It protects the system of piping from any kind of inauspicious impact or thermal deformation. It is easy to install and it prevents from any kind of leakage. 321h fittings provides wide variety of benefits including excellent resistance oxidation to 1500°C, it can be readily welded by most standard processes and it is very ductile and forms easily.
