LP Naval has capability for Weld Overlay for Refining and Process Vessels. The Lclad weld overlay process, developed by L.P. Naval and Engineering Limited, is engineered to combine digitally controlled synergic welding technology with multi-directional programmable automation. The result is a high quality and productive weld overlay process that can be applied to many repair and upgrade scenarios, ranging from replacement of original equipment design materials through to the application of corrosion resistant alloys.
As is often the case 'unplanned' repairs are required to be carried out following internal inspections of vessels and columns during the Shutdown / Turnaround. As we develop, own and maintain our equipment we are always at a state of readiness to mobilise on an 'as required' basis. An extensive library of WPQR and WPS's covers the typical OEM materials of construction of plant and process equipment for weld metal build up (WBU) and corrosion resistant (CRA) alloy requirements
For planned/known scope activities collaborative assessment and review of corrosion and erosion damage by L.P. Naval will enable practical and permanent repair solutions to be applied to critical process equipment, and prevent premature retirement, down-rating, or compromised reliability.
For cases where non-standard repairs are required, we encourage our customers to work with us in the development of repair procedures and mock-ups at our Surat location. Mock-ups enable us to identify suitable repair scenarios and procedures for bespoke or complex repairs, whether it be limited access or unusual geometry.
