Introduction of GB elbow manufacturers
In piping systems, an elbow is a pipe fitting that changes the direction of the pipe.According to the Angle, there are 45° and 90°180° three commonly used, and according to the engineering needs, there are also 60° and other abnormal Angle elbows.Elbow materials are cast iron, stainless steel, alloy steel malleable cast iron, carbon steel, non-ferrous metal and plastic, etc.There are direct welding (commonly used) flange connection, hot melt connection, electric fusion 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, butt welding elbow, etc.Other names :90 degree bend, right Angle bend, love and love bend, etc.
Butt-welding elbow can save space, reduce weight, and more importantly, ensure that the joint part will not leak, with good sealing performance.The compact flange size is reduced by reducing the diameter of the seal, which reduces the cross section of the sealing face.Second, the flange gasket has been replaced by a sealing ring to ensure that the sealing face matches the sealing face.The B value of the 45 degree elbow is the structural size, mainly to bring convenience to the pipeline designer.
For manufacturing and inspection, the measurement of B value is not very convenient.There are two relatively simple methods to detect the value of B, one is commonly used to measure the 45 degree elbow fixture, made of 45 degree Angle, and with different sizes of specifications, when using the butt-welding elbow placed in the fixture;The other is to use the general height caliper direct measurement, and the first size conversion.
A brief introduction to elbow fittings
Elbow pipe fittings are commonly used to connect steel pipes in plumbing installation. They are used to connect steel pipes at the turning point and change the direction of pipes.
Other names for elbow fittings are: 90 degree elbow, right Angle bend, love bend, stamping elbow, press elbow, machine elbow, welding elbow, etc.
Elbow pipe fittings are mainly used to connect two pipes of the same or different nominal diameter, and the pipes can be turned at 90 degrees, 45 degrees, 180 degrees and various angles.
The bending radius of the elbow pipe fitting is less than or equal to 1.5 times of the pipe diameter, and that is greater than 1.5 times of the pipe diameter belongs to the elbow.
