Internal Pneumatic Line-Up Clamp from 6” up to 80”

GENERAL TECHNICAL DATA

DSC01161These type of machine are usually used in certain yard where oil, gas and water pipeline are laying.
The internal pneumatic line-up clamp is a machine which is built and used specifically for the line-up and centering of the oil, gas and water pipeline tubes ,normally used under standard diameters.
The line-up and the centering of the pipes are necessary for a good welding.
The machine mainly is manufactured of a tubular frame with an ogival shape, it has a brake system with two round chucks circular compound of pistons. Once the clamp is positioned and stay there till the end of its use, it is positioned by a direct handling control or by a push rod (supplied with the clamp); the pistons of the two chucks are activated. The machine is fed by an air tank and all its motion, i.d. the translatory motion along the pipe the radial one of the circular parts, depends from the air-pump feeding. The clamp can be controlled directly on the machine or by a control rod.

Special internal line-up clamp for concrete pipes

The Internal Pneumatic Coating Clamp is used for a correct centering and alignment of pipes with internal cement coating.
For the translation, the machine is provided with axial piston air motor and particular trolleys that allows the overpass of internal covering lack in the welding area.
Its operational cycle is carried out with special pneumatic valves that, in production stage, are controlled manually or at a distance with and appropriate control rod.

Electro-pneumatic internal line-up clamp with purge

For the execution of special welding, tight seals and a chamber for the inert gas pressurization are assembled on the clamp.
According with the use, the frame can be totally realized in stainless steel or can becovered with steel only the parts of frame in contact with the pipe.

MAIN LINE INTERNAL LINE-UP CLAMP

The Main Line Electro pneumatic Clamp is used for a correct centering and alignment of pipes.
The Main Line Clamp is properly designed for offshore use.
That machine is composed of frames for a changeable type of use.
The movement is given from air motor while the assembly sliding wheels permit the right centering and alignment.
For a proper use (firing production line with special inclinations) it can be provided of a double motorization system.
The machine is provided of a tension load cell with an appropriate control display to check the critical tension of the Buckle Detector.
Its operational cycle is carried out with electro valves controlled by a remote control connected to the machine with an umbelical cable.
