180 Degree Elbow Manufacturers, Suppliers and Stockists –  ASME B16.9 Standard 180 Degree Elbow Factory

  • Metallica is one of the leading carbon steel 180 degree elbow, stainless steel 180 degree elbow, alloy steel 180 degree elbow manufacturer and supplier. We also manufacture customized products as per customers’ requirements and ensure 100% best quality and tested products.
  • An elbow is a pipe fitting installed between two lengths of pipe or tubing to allow a change of direction, usually a 180° or 90° angle. 180 degree elbows are used to be installed between two lengths of pipe or tube allowing a change of 180° direction. We can provide short radius elbows and long radius elbows. Usually, 180 degree elbow is made of duplex stainless steels, stainless steels, alloy steels, and more.
  • We manufacture welded, seamless and fabricated 180 degree elbows. Elbows manufactured by Metallica offer high service life and at the same time our products are most economically priced. We have a huge customer base for seamless pipes and pipe fittings, allowing us to offer the best discount to our customers. Our focus is clearly to increase the number of customers and help our customers purchase the best quality goods at lowest prices. We offer price guarantee for most of our products i.e we can match any price target if it is reasonably possible.
  • We produce 180 degree elbows as per ASTM, ASME and DIN standards. We produce 180 degree elbows in carbon steel, alloy steel, stainless steel, super austenitic, duplex, super duplex, nickel alloys, titanium, titanium composite and aluminum, etc. Our products are widely used in oil & gas, petrochemical, refineries, power plant, shipbuilding, metallurgy, paper making and other industries.

  • Elbows are categorized based on various design features as below:

    • Long Radius (LR) Elbow is also called LR elbow – means the radius is 1.5 times the pipe diameter
      • L/R 45°Elbow: Long radius 45 degree elbow changes the direction by 45 degrees.
      • L/R 90°Elbow: Long radius 90 degree elbow changes the direction by 90 degrees.
      • L/R 180°Elbow: Long Radius 180 degree return bend allows complete reversal of flow.
    • Short Radius (SR) Elbow is also called SR elbow, – means the radius is 1.0 times the pipe diameter
