Precision Engineering Capabilities for Pressure Vessels
LTi Vessco provides comprehensive capability for safety-critical pressure equipment, combining precision welding and fabrication with disciplined engineering control. We take projects from design input through forming, fit-up, coded weld execution, and staged inspection, ensuring repeatable integrity on complex vessel geometries.
We manufacture pressure vessels and pressure equipment in a wide materials range including nickel alloys, duplex, super duplex, and other customer-specified grades to suit demanding duty requirements. With almost 20 years’ experience, our coded welders and engineers deliver fully traceable solutions for nuclear, power generation, water and utilities, petrochemical, and industrial process sectors - where compliance, performance, and long-term integrity are non-negotiable.
Where specified, we complete in-house pressure testing and NDT prior to dispatch, supported by full traceable documentation. This integrated approach strengthens build accuracy, reduces handovers, and ensures every vessel is supplied ready for installation and long-term regulated service.
