Product Presentation

In a piping system, an elbow is a fitting that changes the direction of a run. A kind of connecting pipe fitting commonly used in pipeline installation, connecting two pipes with the same or different nominal diameters to make the pipeline turn at a certain angle, and the nominal pressure is 1-1.6Mpa.

The common angles are 45 ° and 90 ° 180 °. In addition, there are 60 ° and other abnormal angle elbows required by the project.

The materials of elbows include cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, nonferrous metals and plastics.

The common connection methods with pipes include direct welding, flange connection, hot melt connection, electric melt connection, threaded connection and socket connection.

Radius of Curvature

It is divided into long radius elbow and short radius elbow.

Long radius elbow refers to the outer diameter of the pipe whose curvature radius is equal to 1.5 times, that is, R=1.5D;

Short radius elbow means that its radius of curvature is equal to the outer diameter of the pipe, that is, R=1.0D.

(D is the elbow diameter, R is the radius of curvature).
