Technical requirements for production of elbow by elbow machine
The radius of curvature should be controlled when elbow machine is produced.
For example, if the radius length is 1.5d, the radius of curvature must be within the required tolerance range.Because most of these pipe fittings are used for welding, in order to improve the welding quality, end car into groove, leave a certain Angle, with a certain edge, this one is more strict, how thick, Angle deviation range has a regulation, for how much and a lot more than pipe item geometry size.
The surface quality and mechanical properties of the elbow are basically the same as that of the pipe.For the convenience of welding, the material should be the same as the steel of the connected pipe. |
