Pipe beveling is the process where an angle is formed between the edge of the end of a pipe or tube and a plane perpendicular to the surface.
The inclined end of the inclined end of the pipeline is simply a joint with a specific inclination angle. In fact, it is processed before welding two pipe lines, and with the help of the bevel machine, an angle is formed at the edge of the pipe end. The slope of a pipe or pipe is usually used to prepare ends for welding. For safety and beauty reasons, it can also be used for deburring of cutting ends.
The wall thickness of the pipe is subtracted from the outer diameter of the pipe. For example, if you have a pipe with a diameter of 6 inches and a wall thickness of 2 inches, you need to subtract two from six to get four PVC pipes and use a chemical solvent to form a seal between the pipe and the pipe.
Measure the required length of the pipe to be installed, and remember the extra length required to insert the pipe into the fittings. Mark this length on the pipe.
Beveling ends can be made into various angles, achieving the better welding seam. Common beveled ends for butt joints are I—Type butt joint, single—V beveled end, double—V beveled end and single U—beveled end.
Beveled angle refers to the angle between the two beveled surfaces. Beveled face angle, normally used for single-U type, refers to the angle between the beveled surface and the vertical line to the pipe itself. The root opening refers to the gap between the roots of both pieces before welding, to ensure the roots get complete welding. The root radius for single-U beveled end is to increase the transverse space between the roots, making the welding reach the bottom of the root.
We can apply any type of Bevel to any degree required.
For the ends of pipes are 3 standard versions available.
The PE pipes will generally be used for the smaller diameters pipe systems and in combination with Slip On flanges and Socket Weld fittings and flanges.
The TE implementation speaks for itself, this performance will generally used for small diameters pipe systems, and the connections will be made with threaded flanges and threaded fittings.
The BE implementation is applied to all diameters of buttweld flanges or buttweld fittings, and will be directly welded (with a small gap 3-4 mm) to each other or to the pipe. Ends are mostly be beveled to angle 30° (+ 5° / -0°) with a root face of 1.6 mm (± 0.8 mm).
Piping lengths from the factory not exactly cut to length but are normally delivered as:
