Pipe Elbow Fittings 180° 168.3*7.11 LR Elbow ASTM403 WP304 changes the direction elbow
In a pipeline system ,an elbow is a pipe fittings that changes the direction of the pipeline .According to the angle ,there are 45°and 90° 180° three most commonly used ,in addition ,according to the needs of the project ,there are other abnormal angle bends such as 60. The materials of elbow are cast iron ,stainless steel, alloy steel ,malleable cast iron ,carbon steel ,non-ferrous metals and plastics
The ways to connect with the pipe are :direct welding (the most commonly used way)flange connection ,hot melt connection electric fusion connection ,thread connection and socket connection ,and so on .Technical underground industry technology can be dinided into: welding elbow ,stamping elbow ,push elbow ,casting elbow ,butt welding elbow and so on.Other names :90 degree elbow, right angle bend,etc
classification
1,According to the production method ,it can be divided into push ,pressing ,forging ,casting and so on.
2,According to the manufacturing standard ,it can be divided into national standard ,electric standard ,ship standard ,chemicl standard ,water standard ,American standard ,German standard ,Japanese standsrd ,Russian standard and so on .
3,According to its curvature radius ,it can be divided into long radius elbow and short radius elbow .A long radius elbow refers to the outer diameter of a tube whose curvature radius is equal to 1.5 times ,that is,R=1.5D short radius elbow means that its curvature radius is equal to the outer diameter of the pipe ,that is R=1.0D (d is the diameter of the elbow and R is the radius of curvature).
4,According to the pressure grade ,there are about 17 kinds which are the same as the pipe standards in the United States ,including Sch5s Sch10s ,Sch30s ,Sch40s ,STD ,Sch40 ,Sch60 ,Sch80s ,Xs ,Sch80, Sch100,Sch120 ,sCH140 ,Sch160 andXXS
5,According to different shapes and uses ,it can be divided into grooves elbow ,ciamping elbow ,double bearing elbow ,flange head ,different diameter elbow ,rigid seat elbow ,inner and outer tooth elbow ,punching.
