Pipe elbows

Pipe elbows are used to be installed between two lengths of pipe or tube allowing a change of direction,usually these elbows distinguished by connection ends.

ASME B16.28 Buttwelding Short Radius Elbows

We are engaged in supplying wide range of eblows.

Key Specifications/Special Features and Materials

the material is selected accoding to the application use such as high temperature use,sanitary fitting,regular industrial use etc.

  • Carbon steel: ASTM A234 WPB, WPC, ASTM A420 WPL1, WPL3, WPL6, WPHY-42/46/52/56/60/65/70
  • Stainless steel: ASTM A403 WP304/304L, WP316/316/L, WP321, WP347 and WPS31254
  • Alloy steel: ASTM A234 WP1/WP12/WP11/WP22/WP5/WP7/WP9/WP91
  • Abrasion resistant material:Ceramic lined, Ceramic tile lined , Bi-metal clad pipe,
  • Manufacturing standards: ANSI, ISO, JIS and DIN.

The ends of pipe elbows may be machined for butt welding , threaded , or socketed , so the elbows are consist of butt weld,thread elbow, socket elbow and other series.

Application of pipe elbows:

Petroleum, chemical, power, gas, metallurgy, shipbuilding, construction, etc.

ELL & ELLS
  1. A wing of a building at right angles to the main structure.
  2. A right-angled bend in a pipe or conduit; an elbow.

Elbows are design features as below

An elbow is a pipe fitting installed between two lengths of pipe or tubing to allow a change of direction, usually a 90° or 45° angle, though 22.5° elbows are also made.

Long radius (LR) pipe elbows

Long radius elbows Long Radius (LR) Elbows – radius is 1.5 times the pipe diameter

Short radius (SR) pipe elbows

Short radius elbows Short Radius (SR) Elbows – radius is 1.0 times the pipe diameter

Note:
  • 90 Degree Elbow – where change in direction required is 90°
  • 45 Degree Elbow – where change in direction required is 45°
  • L/R - Long radius, S/R - Short radius

Abrasion resistant Bend & elbow

Abrasion resistant piping systems are widely used at coal-fired power plants for a variety of purposes, including the conveyance of coal ash slurry to nearby settling ponds, the transfer of limestone slurry to absorber spray towers for removal of sulfur dioxide (SO2) and hydrogen chloride (HCl) from flue gases and for transporting away the calcium sulfate by-product of the flue gas desulfurization process.

Features of Alumina Ceramic lined elbow:
Alumina is a cost effective and widely used material in the family of engineered ceramics.

Alumina ceramics have been developed and optimized for maximum wear resistance and corrosion resistance.
