We serve the oil refining and petrochemical industries with on-site process vessel upgrade, repair, and turnkey overhaul solutions.
Our associated mechanical services are a resource developed to compliment the needs of the weld overlay activities, and additionally provide a stand alone capability for petrochemical process plant turnarounds.
The Vclad® weld overlay process, developed by DTEC, 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.
Corrosion and material degradation in process vessels present plant operators and designers with many challenges. Vclad® weld overlay provides the solution to managing repairs and material upgrades on site within the constraints of turnaround schedules
Unplanned repairs are often required 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 cover 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 and anticipated scope activities collaborative assessment and review of corrosion and erosion damage by DTEC Engineering will enable practical and permanent repair solutions to be applied to critical process equipment, 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 UK location. Workshop based repair simulation enable us assess application feasibility and develop procedures for bespoke or complex repairs, whether it be limited access, or unusual geometry.
DTEC Engineering provide specialist repair services where weld overlay cannot be considered due to technical reasons. Insert replacement of vessel sections provides a solution to various conditions and damage cases.
