A brief introduction to elbow classification

A brief introduction to elbow classification  

The company mainly produces various types of elbow pipe fittings, the following is a brief introduction of elbow classification for customers: 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.  The radius of curvature of the short radius elbow is equal to the outer diameter of the pipe.  R=D, where D is the diameter of elbow and R is the radius of curvature.  Elbow is divided into a variety of models, the commonly used models are STD and XS.  

Elbow production method:  Push the material for thermal system, push the machine head or is a horn core mandrel, mandrel thin coarsens, elbow push system process is a process with a curved hole diameter, back support, under the section through the mandrel, there is a car, car through hydraulic transmission, some mechanical transmission by screw transmission not to push the car after car going forward pushing down the mandrel pipe,  There is an induction ring outside the mandrel to heat the tube, heating, and then the car to push the tube down, processing a good.  

According to the process after sandblasting treatment, the inner and outer surface of the elbow to remove the iron oxide, the two ends of the groove treatment all over the welding.  

To select the specifications, put forward the pipe material, such as 90 degree elbow, through which the radius of curvature can calculate the need to feed how much, and then cut off the pipe.  The cut elbow steel pipe is pushed and corrected, and the elbow pipe reaches the size of the finished product after being corrected by the correction mold and equipment.  A brief introduction to elbow classification
