HGND-C series copper lining pneumatic internal line up clamp is mainly used for pipeline construction of automatic welding and semi-automatic welding. It has the function of conventional pneumatic internal line-up clamp features. Meanwhile, it has copper lining features. That is, during the welding process, the copper lining closely fitted to the inner wall of welding road, and achieve the purpose of unilateral welding and double-sided forming. It is an ideal and decicated pipeline construction that can conduct welding automatically and deal with the problem of difficult root welding during the semi-automatic welding process. Suhigo copper lining pneumatic internal clamp has been used in pipeline construction in domestic market and overseas market.

Technical Parameters of Copper Lining Internal Clamp:

Technical Features of Copper Lining Internal Clamp:

1) The copper lining internal clamp has compact structure, can reduce the expanding distance, ensure large tension force in pipe orifice and ensure the clamp accuracy.

2) With unique design, can avoid the occurence of strong current due to sharp corners on the surface of the copper lining, avoid weld beading on the back and solve the impact of sharp metals formed inside on sweeping lines.

3) It solves the problem that copper elements fuse into steel baseplate occuring after the edge of cooper lining of traditional design is burnt and ensure the welding quality of welds.  Therefore, the copper leakage phenonmenon will not occure in this welds.
