Internal Line Up Clamp (ILUC)
Pneumatic internal pipe alignment clamp and purge system for 4" to 60" — precision fit-up for flawless root passes.
Overview
The TIP TIG Internal Line Up Clamp (ILUC) works inside the pipe to simultaneously align and purge two pipe joints for external welding. Pneumatically operated, it ensures perfect concentricity, consistent root gap, and an inert purge atmosphere — everything you need for clean root passes. Available for pipe sizes from 4" to 60" (101.6 mm to 1524 mm).
Key Features
Combines the functions of a pipe welding clamp and a purge system in one tool — clamp the joint and establish an inert atmosphere simultaneously, eliminating a separate purge setup.
Air-powered clamping delivers consistent, controllable force across the full pipe diameter range. No hydraulic fluids, no contamination risk near the weld zone.
Covers pipe diameters from 101.6 mm to 1524 mm (4" to 60") — from process piping to large-diameter transmission pipelines, onshore and offshore.
Internal clamping leaves the entire pipe circumference free for welding — no external clamps, dogs, or tack welds interfering with the root pass.
