ASTM A234 AS Buttweld Fittings, Low Alloy Steel 90 Degree Elbow and Tee Supplier in Mumbai

Alloy Steel Pipe Fittings Manufacturer in India

What Is Alloy Steel Pipe Fittings?
Alloy steel pipe fittings are versatile components designed possessing a range of alloys. The content of alloy ranges from 1% up to 50%. The higher the content of alloys greater is its corrosion and oxidation resistance properties. The versatile fittings play an important role in determining the characteristics of the flow of fluids and gases across stress-induced environments.

Alloy Steel Short Vs Long Radius Elbow
Elbows are fittings that are employed to change the direction of the flow of fluids and gases. The versatile grade is designed in short or long radius and can be distinguished in certain aspects.

  • Alloy steel short radius elbow is designed with a radius of curvature that is equal to its outer diameter. An alloy steel long radius elbow has a radius of curvature that is 1.5 times its outer diameter.
  • Long radius elbows are used in applications where there is wear and tear in the system. A short radius elbow is preferred in a normal system.
  • A short radius alloy steel grade is seen in use in tight areas, while long radius elbows are used in normal working conditions.

Alloy Steel Tee Vs Lateral Tee

  • Alloy steel tee is designed in the shape of a T, while an Alloy steel lateral tee is designed in the shape of a Y.
  • A steel tee has two outlets that are opposite to each other, while the branch port is at 90 degrees. In a lateral tee fitting the 2 branch ports are seen in opposite directions. Here the branch port may be at 45 or 60 degrees.

Can You Harden Chrome Moly Fittings?
Chrome fittings are generally hardened by the carburization process. Here the metal absorbs carbon as the metal is heated with carbon-bearing material or charcoal. The fittings are later quenched, which helps in reducing wear and tear.

Does Chrome Moly Pipe Fittings Need To Be Heat Treated?
A chrome moly pipe fitting possesses superior strength and other properties that don’t require the fitting to be heat treated. These fitting can be easily heat treated following work-hardening processes.

We keep huge stock of Chrome Moly Fittings and Alloy Steel Concentric / Eccentric Reducer accordance to ASME B16.9.
