1.5 D bend
1.5D elbow refers to the bending radius of the elbow is 1.5D, which is 1.5 times the diameter of the required bending object (pipe fitting).
The use of 1.5D elbow: 1. Reduce pipe stress. The use of long radius elbows can increase pipe flexibility. 2. Reduce pipe pressure drop. The equivalent length values of 1D elbow and 1.5D elbow are different in the calculation process of pressure drop, but the difference is not large. However, if the number of elbows in the whole pipe system is large, there will be some adjustment effect. 3. Reduce the pulse power of the fluid to the pipeline. The larger the curvature radius of the elbow, the less dynamic load the fluid exerts on the pipe system.
In piping, a bend is a piece of pipe that changes the direction of the pipe.
According to the Angle, there are 45° and 90°180° three commonly used, in addition, according to the needs of the project also includes 60° and other abnormal Angle elbow.
Elbow materials include cast iron, stainless steel, alloy steel, malleable iron, carbon steel, non-ferrous metals and plastics, etc.
The connection mode with the pipe includes: direct welding (common way) flange connection, hot melt connection, electric melt connection, thread connection and socket type connection.
According to the production process can be divided into: welding elbow, punching elbow, push elbow, casting elbow, butt welding elbow, etc.
Other names: 90 degree bend, right Angle bend, etc.
Because elbow has good comprehensive performance, so it is widely used in chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, freezing, sanitation, plumbing, fire fighting, electric power, aerospace, shipbuilding and other basic engineering.
