Pipe Bends & Elbows Manufacturers & Suppliers

What is the difference between Pipe Bends and Pipe Elbows?

Pipe bends are generally made, as per custom piping design requirements of the customers, whereas elbows are manufactured in conformity to standard size and specifications eg: ASME B16.9, MSS SP-43 (Dimensional Specification for 45 Degree, 90 Degree and 180 Degree Short Radius & Long Radius Elbows). Pipe bends can be manufactured based on custom radius requirements provided by customers such as 3D, 5D, 6D, 10D, 15D or any other custom radius. Elbows are generally used, when the radius required is 1D, 1.5D or 2D, but when the curvature exceeds 3D, bends are most commonly utilized.

  • SR (Short Radius) Elbows or Bends: These elbows have a Center-to-Face dimension of 1.0 X diameter. They are typically used in tight areas where clearance is the main issue.
  • LR (Long Radius) Elbows or Bends: These elbows have a Center-to-Face dimension of 1.5 X diameter. They are the most common type of elbow and used when space is available and flow is more critical.
  • Custom Radius Pipe Bends: R=3D~10D, with Product Angle of 0°~180°
  • Reducing Elbows or Bends: A reducing elbow is a type of fitting which is used to join two pieces of pipe of different sizes.

Metline is a reputed and professional manufacturer of seamless and welded elbows and pipe bends. All our pipe bend and elbow products are manufactured with high quality raw materials, and can be supplied with test certificates according to EN 10204 3.1. with full traceability.

Seamless Pipe Bends

Seamless buttweld pipe fittings are manufactured from seamless pipes and tube by hot or cold extrusion, forming and machining process. We are a leading supplier and manufacturer of seamless buttweld pipe fittings in India. Most of the seamless buttweld pipe fittings in standard sizes and grades are available ex-stock for immediate supply to our customers.

Welded or Fabricated Pipe Bends

Seam welded buttweld fittings are produced from hot rolled steel pipes. As per customer requirements, we can also manufacture and offer pipe bends manufactured from hot rolled plates, formed into half shells or segments and then welded on the seams.

Pipe Bends & Elbows are categorized based on various design features such 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

  • Short radiu 45°Elbow: Short radius 45° elbow changes the direction by 45 degrees.
  • Short radius 90°Elbow: Short Radius 90° elbow is same as LR90 except for the measurement between end of elbow to center line is 1 x NPS.
  • Short radius 180° Elbow: Short Radius 180° return bend allows complete reversal of flow

Elbows are generally used, when the radius required is 1D, 1.5D or 2D, but when the curvature exceeds 3D, bends are most commonly utilized.
