ILUC Series Internal Line-Up Clamps ILUC 3840

The ILUC clamp series was developed to provide internal line up for welding of small-bore piping systems. This modular system allows for different configurations to fit a wide variety of applications. Available options include copper backing for root pass integrity, purge dams for TIG welding, and a pneumatic drive system for horizontal operations. For vertical use, an emergency brake system is actuated on loss of pneumatic pressure or electrical current preventing the clamp from dropping into the pipeline.
