Stainless Steel 321 Pipe Fittings

Since 2008, We Have Been manufacturer And supplier Of ASTM A403 WP321 Elbow And SS 321H Tee/ Reducer In Mumbai, India


Stainless Steel 321 Pipe Fittings

Fittings used to connect different components of the piping system are available in various grades and materials. Stainless Steel 321 Pipe Fittings is one such type that is non-magnetic and is used in many industrial applications. ASTM A403 WP321 Elbow has some amount of titanium added to it. This helps in welding the fittings without the risk of intergranular corrosion. Moreover, as per SS 321H Tee manufacturer In India,  the addition of titanium also assists in avoiding chromium carbide precipitation that might occur due to exposure to a higher temperature

UNS S32100 Reducing Tee is preferred due to its ability to work in high pressure and temperature even at a higher temperature. 8" X 4" Inch SS 321H Reducer is also said to reduce pitting and crevice corrosion and offer higher resistance to chloride stress corrosion cracking. Moreover, these fittings also provide sulfide stress corrosion resistance and are easy to weld and conform. SS 321H Long Stub End can resist oxidation up to 1500 degrees F. They offer high creed and stress rupture properties along with good low temperature toughness. They are primarily installed between 2 ends of the pipe to help them in changing the direction of the flow. 

Werkstoff Nr. 1.4541 Pipe End Cap can be hardened only by cold working heat treatment does not harden it. A403 WP 321 Stainless Steel Buttweld Fittings are used in power plants and chemical factories as they make the piping system compact and reliable. They protect the system from negative impact or thermal deformation. 321 SS Pipe Bends is said to be easy to install and maintain. The carbide precipitation can be avoided at a temperature range of 427 degrees C to 816 degrees C. ASME A403 321H Concentric/ Eccentric Reducer manufactured by us are supplied to various countries without any hassle of approval since they are manufactured as per international standards.

How To Calculate Stainless Steel WP321H Tee Center?


  • Stainless Equal Tee Formula
  • 90 Degree Elbow
  • 4" X 4" Inches
  • Pipe Outside Daimeter (O.D.) X 2/5
  • For Example
  • 4 Inches Pipe (O.D.) Outside Daimeter = 114.30
  • 114.30 X 2 = 228.60 / 5 = 45.72 (MM/ Millimeter) cut back
