The pneumatic inner clamp is the key construction equipment for high efficiency and high precision fitting-up of long distance pipeline. It can improve efficiency by 100% relative to the external mouthpiece; Compared with the external mouthpiece, the accuracy of the mouth is improved by 200%.
The inner mouthpiece is mainly used to pair two welded steel pipes in the construction of oil and gas pipelines. With the continuous development and progress of pneumatic internal mouthpiece, more and more pneumatic internal mouthpiece is used in urban water supply and heating construction. Through the use of pneumatic internal mouthpiece not only to ensure the speed of construction but also improve the quality of construction!
At present, domestic and foreign pipeline construction welding process requires that when the pipeline is welded at the butt joint, a certain gap should be left at the butt joint of the two pipelines. However, most of the current construction applications are non-adjustable, and backward technologies such as feeler gauge and screwdriver are also used during construction. With the progress of pipeline welding technology and the booming development of pipeline construction, our company independently develops and produces a kind of adjusting pneumatic internal port device with simple structure, convenient operation, fast and low cost.
Main performance features
1、Compact struc,stable performance,easy operation.
2、High precision,wide application.
3、Limiting device in the supporting system.
4、Quick adjustment,easy maintenance.

Copper Lining Pneumatic Internal Clamp is designed for automatic and semi-automatic pipeline welding , which has the function of conventional pneumatic inside the mouthparts at the same time, have brass function, achieve the purpose of the single side welding, double-sided molding.
Main performance features
1、Compact structure，stable performance.
2、High precision，wide application.
3、Unique structural design, solve the influence on the sweeping line caused by the forming of the sharp metal in the internal molding.
4、Solved the phenomenon of copper seepage , guarantee the welding quality.
Gas Shielded Internal Clamp is mainly used in the construction of carbon steel and stainless steel composite pipe pipeline. In the construction, after the pipe alignment is completed with the air protection coupler, the gas replacement is carried out. In the welding process, the inert gas is used to ensure that the stainless steel lining is not oxidized.
