ASTM A234 Pipe Fittings LR 90 Seamless Elbow Pipe Connection Water Supply

Elbow In the pipeline system, the elbow is a pipe fitting that changes the direction of the pipeline. According to the angle, there are three most commonly used ones: 45° and 90°180°. In addition, it also includes other abnormal angle elbows such as 60° according to engineering needs. The elbow materials are cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics. The ways to connect to the pipe are: direct welding (the most common way) flange connection, hot melt connection, electrofusion connection, threaded connection and socket connection, etc. According to the production process, it can be divided into: welding elbow, stamping elbow, push elbow, casting elbow, etc. Other names: 90 degree elbow, right angle bend, love and bend, etc.

1. Divide carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon leaching, PVC, PPR, etc. by material.

2. According to the production method, it can be divided into pushing, pressing, forging, casting, etc.

3. According to the manufacturing standard, it can be divided into national standard, electric standard, water standard, American standard, German standard, Japanese standard, Russian standard, etc.

4. According to its radius of curvature: it can be divided into long radius elbow and short radius elbow. Long radius elbow refers to the outside diameter of the tube whose radius of curvature is equal to 1.5 times, that is, R=1.5D. A 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 diameter of the elbow, R is the radius of curvature).

5. According to the pressure level: there are about seventeen types, which are the same as the American pipe standards, including: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, SCH1 elbow, seated elbow, internal and external tooth elbow, stamping elbow, push elbow, socket elbow, butt welding elbow, inner wire 00, Sch120, Sch140, Sch160, XXS; the most commonly used are Two kinds of STD and XS.

6. According to different shapes and uses, it can be divided into: groove elbow, ferrule elbow, double bearing elbow, flange elbow, reducing elbow, etc.

use
A commonly used connection pipe fitting in pipeline installation, connecting two pipes with the same or different nominal diameters, so that the pipeline can be turned at a certain angle.
