Manual Internal Line-Up Clamps
Manual ILUCs are used to accurately align and back purge components, for welding by hand or with orbital welding heads.
Widely used when welding :-
- Stainless steel tube, fittings, valve and filter bodies, for the food, dairy, brewery, chemical, bio-technology, cryogenics and pharmaceutical industries.
- Non-ferrous materials such as copper-nickel pipework for ships and submarines.
When mounted into turntables and lathes, these same manual ILUCs become a versatile system for welding pipework and circumferential components.

Pipeline Welding Internal Line-Up Clamps
Hydraulically expanded clamps provide the power to handle the thicker wall pipes. With built-in purge systems to protect the underbead from contamination, these clamps are used when Tig welding stainless steel and specialist steels.
Projects include :-
- Pre-fabrication of stainless steel clad pipework.
- Welding magnet housings for a particle accelerator
With additional purge dams and purge sampling ports, these Pipeline Welding ILUCs are used for Duplex Stainless Steel.
Projects include :-
- Cross country and Offshore duplex and super duplex pipelines.
- Gas processing plant duplex pipework.
