Pilgrim’s Coupling Hole Alignment Tool (CHAT)

The Coupling Hole Alignment Tool (CHAT) is a further development from the Pilgrim product portfolio.

The Coupling Hole Alignment Tool (CHAT) is a further development from the Pilgrim product portfolio. Designed in response to OEM maintenance and end-user requirements. It achieves coupling hole alignment quickly and to a tolerance that permits effective bolt installation or removal.

The CHAT hydraulically expanding tool is based upon the same principle as the Radial Fit Bolt saving time and therefore reduces cost during the alignment and closure of shaft couplings. Depending upon coupling size, each CHAT package consists of between three and four tool assemblies. The tools are inserted into equispaced flange holes and are simultaneously pressurised to align the coupling holes. The coupling faces are then closed using the tools in preparation for installation of the coupling bolts.

Deep-sea pipe laying at depths up to 2,500m is a complex and potentially dangerous task requiring highly specialised skills and equipment.
