Different manufacturers have different names. Then the corresponding specifications of welded pipe mould keyways are 8, 10 and 12, and the corresponding specifications of large machines are 18 and 20. These are just conventional designs, There are some exceptions. For some industrial pipe 50 type pipe making machines, the specification of the keyway of the welded pipe die is 12, which indicates that the width of the keyway of the shaft diameter of the pipe making machine is 12. These are special designs.
