Steel pipe bend two pipes into a certain angle and connects them together to change the direction of the pipe.API 5L B is belong to American Standard which is represents carbon steel bend.Shanghai Zhucheng Pipe Fittings Manufacturing Co Ltd is an experienced pipe fittings manufacturer who supplying API 5L B material of fittings for years.

 

Product features

  • Since there is no irregular surface inside the pipe and the fluid does not have to change direction suddenly, the flow of bend is usually smoother.
  • They can be almost any bending radius and angle.
  • Pipe bends are commonly produced on site to meet a specific need by hot induction bending or cold bending.

 

Pipe Bend VS Elbow

 

  • Bending Radius of Bend and Elbow

Bending Radius of  Bend and Elbow

Steel pipe bend radius: Above 2 times of D, so there are 2D, 2.5D, 3D, 5D, 6D, 7D or 8D pipe bend.

Steel pipe elbow radius: R=1D or R=1.5D or 2D. Below 1.5D is short radius elbow, and more than 1.5D but not over 2D is long radius elbow.

 

  • Different of manufacturing processes

Bend: Could be bend directly from a finished pipe with cold bending processes, to different degrees.

Elbow: Shall be made according by standard manufacture procedures, with hot finishing or hot bending, to a certain degree, 45°, 90° or 180°.
