Automatic welding has strict requirements on pipe bevels, normally the bevel can not be made in the pipe factory since the bevel surface is easy to be rusty and damaged during transportation and storage process. Pipe facing machines are specially for pipe end preparation on the project site, high accuracy pipe bevels can help to reduce the automatic welding repair rate.

Good pipe facing machine ensure even root face dimension around the circumference even though huge pipe ovality, even at the condition of big wall thickness, high precision pipe facing machine can well avoid machine vibration to achieve good surface smoothness, further to ensure the welding quality, hence when we choose pipe facing machine, we must focus on whether the pipe facing machine can make consistent bevels which dimensions and surface quality can be fully ensured, especially at the conditions of big pipe diameter and thick wall.

CRA claded pipes are even more difficult to be beveled, the CRA material is soft, during cutting process, the excessive heating cause high temperature of cutting tool and metal scrap adhesion, easy damage cutting tool , in addition, two type of steel material with different mechanical property also cause stress imbalance and vibration of cutting holder, high quality pipe facing machine not only has good performance at carbon steel cutting but also CRA claded pipe and stainless steel.

Deping’ pipe facing machine and hydraulic power unit (HPU) features:

1. The feeding movement of disk of cutting tool is support by two guiding shafts (one for each side), comparing to single side guiding shaft, it present better stress allocation, no disk movement when cutting pipe especially thick pipe, so the bevel dimensions and surface smoothness are better

2. Two rows of expanding clamp shoes are powered by two hydraulic cylinders independently.

two rows of clamps shoes can support against inner wall closely, good clamping effect when pipe ovality or bad straightness

3. There are four support legs attached on pipe facing machine, easy for transport and storage

4. The cutting tool position is adjusted by a wedge with easy operation.

5. Work well with various materials: carbon steel, CRA clad, stainless steel etc.

6. One HPU can work for all pipe facing machine models from PFM0612/1224/2436/3648/4860, it is helpful for projects cost saving
