Internal line up clamp is mainly used to align two pipes in long distance of oil and gas pipeline construction projects.With the development of Internal line up clamp, urban water and heat pipeline construction also begin to choose the Internal line up clamp finish the pipe aligning.
Internal line up clamp not only ensure the efficiency but also improve the quality of the pipeline construction.

Internal line up clamp on international market are basically same on principle and the machinery structure. Can be divided into expanding mechanism、self-propelled mechanism
and air tanks several parts.
Our company's Internal line up clamp is the new generation pneumatic Internal line up clamp after analyzing the characteristics of similar products in domestic and overseas.Luoyang Deping Internal line up clamp are with self-propelled and self-braking function,grade ability 20°,good technical performance and simple operation, low failure rate, align precision is higher than other international brand products, bring more convenience to the pipeline construction.
Internal line up clamp Minimum Model DKQ168/ 6 inches, Maximum model can be 80 inches.
According to the different welding method Internal line up clamp main divided into standard pneumatic Internal line up clamp and Internal line up clamp with copper backing shoes. Usually manual welding need to use standard pneumatic Internal line up clamp ;Automatic welding and semi-automatic welding technology need pneumatic Internal line up clamp with copper backing shoes.
According to the different control methods Internal line up clamp can be divided into pneumatic and electric control internal line-up clamps. As the special environment of offshore projects,internal line up clamp normally use electric control, which with battery alarm .Also can be pneumatic& electric double control according to the customers demand.

We also have Internal line up clamp with purge system, mainly suitable for GTAW - tungsten electrode gas shielded welding. it can align pipes quickly ,forming an inert gas protection inside. it is equipped with an oxygen content measurement device, which can monitor the oxygen real-time to ensure the welding quality.
Deping company also specially designed Internal line up clamp for short pipe welding . In order to alignment pipe better under different environmental conditions, and adopts hydraulic pressure which is much better for out of round correction.

With the development of manufacturing technique, Internal line up clamp get more and more attention of people.
Please pay more attention in the process for the below points
1.Internal line up clamp must be debugging before the first running;
2.Each time before start working, it is necessary to check whether the brake is reliable;
3.Equipment of cylinder and all kinds of pneumatic components must be used under the specified working pressure,do not allow to use overpressure, undervoltage, otherwise it will cause leakage, such as equipment damage and failure fault etc.
