Welded Elbow Fitting
Welding elbow fitting, it can be cut on the pipe or steel plate after welding, its specifications can be very large.The number of sections and radius of bending are determined freely by the producer.Welding bend is not very smooth, both bending radius is not big, generally 1 times the diameter of the pipe.
Welded elbow dimensions
According to the pressure grade, there are about 17 kinds, which are the same as the American pipe standard: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS;Sch80, Sch100, Sch120, Sch140, Sch160 and XXS, among which STD and XS are the most commonly used.
According to the Angle of the elbow, there are 45° elbow, 90° elbow and 180° elbow.In this way, there are many kinds of elbow. When ordering goods, the following expression method is often taken: for example, "LRSTD90°8", which represents the long radius, pressure grade is STD, and the 8" elbow of 90°;Another example is the "SRXS45°4" elbow with short radius and pressure class XS, 45°.
