Seamless elbow model representation method

Seamless elbow model representation method  

Seamless elbow can be divided into long radius elbow and short radius elbow according to its radius of curvature.  The radius of curvature of the long radius elbow is equal to 1.5 times the outer diameter of the pipe, that is, R = 1.5D.  The radius of curvature of the short radius elbow is equal to the outer diameter of the pipe, that is, R = D.  Where D is elbow diameter and R is radius of curvature.  

According to the pressure grade, there are about 17 kinds of pipe standards, which are the same as those in the United States: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS;  Sch80, Sch100, Sch120, Sch140, Sch160, XXS, among which STD and XS are commonly used.  

According to the Angle of the elbow, there are 45 degrees elbow, 90 degrees elbow and 180 degrees elbow.  

In this way, there are many kinds of elbow, generally adopted as follows: for example, "LR STD 90 degrees 8", indicating long radius, pressure grade STD, 90 degrees of 8" elbow;  For example, "SR XS 45O 4" stands for short radius, pressure class XS, 45 degree 4" elbow.  

The company mainly produces various types and materials of seamless elbow pipe fittings, seamless elbow pipe fittings are mainly used for pipe turning, in the process of installation and use of simple operation, the installation method is direct welding or flange connection.  Seamless elbow pipe quality assurance, low price, welcome the need of customers consultation order!
