ABSTRACT:
A lineup clamp (10) is disclosed which is particularly suitable for clamping to smaller diameter pipe sections with their ends abutting for welding. Pipes less than twelve inches in diameter can be clamped by the clamp (10). The clamp includes a first resilient element (24) and a second resilient element (28) separated by a separator (26). A hydraulic cylinder (20) is activated to resiliently deform the elements (24, 28) against the separator and the inner surfaces of the abutting pipe sections to clamp the pipe sections in alignment for welding. The clamp is released by removing pressurized hydraulic fluid from the hydraulic cylinder and permitting the resilient elements to rebound to their relaxed configuration.
