Success Stories
Every project we execute is proof of our technical capability, commitment, and international standards. These are some of the works we have developed for leading companies in the most demanding sectors of the industry.
Reactor Challenge (UOP II Unit)
Barrancabermeja Refinery
We successfully intervened in the upper platforms of a reactor in a high-risk environment. Faced with physical field restrictions, our team demonstrated real-time reengineering by modifying scaffolding and structural grating to ensure the passage of our machinery.
Working in continuous 24/7 shifts, we achieved the impeccable grinding of a 4-meter-long bevel with exact geometry. This project reflects our value promise: solving complex in-situ problems, minimizing plant shutdowns, and delivering results to international standards. We are your strategic ally in high-engineering solutions.
High-Precision Engineering:
Ovality Correction on Coke Drum
We successfully intervened in large-scale critical components through advanced machining solutions. In this complex project, we corrected the ovality and structural deformation of a Coke Drum — equipment subjected to extreme operating conditions.
Using laser alignment systems and specialized cutting tools, we performed millimeter-precise concentric grinding that restored the equipment to its original design tolerances. This achievement demonstrates our capacity to resolve severe geometric challenges, ensuring asset reliability, extending service life, and drastically minimizing plant downtime.
Tube Bundle Fabrication
for Heat Exchanger
At METALPREST GROUP, we specialize in the fabrication of tube bundles for heat exchangers, backed by more than 40 years of experience and international certifications that guarantee quality and trust. Everything begins with digital design and simulation, where we validate wall thicknesses, working pressures, and equipment configuration to meet the highest engineering standards.
The process continues with the precise assembly of the tube bundle skeleton, guaranteeing stability and alignment throughout the structure. Tubes are inserted into the sheets and mechanically expanded to achieve a perfect fit before final joints, which are completed using high-precision orbital welding. Each joint undergoes vacuum testing, non-destructive testing, and rigorous quality controls — including metrological verification and hydrostatic testing that simulate real operating conditions. The result is a reliable tube bundle, manufactured with precision, safety, and excellence. At METALPREST GROUP, we transform engineering into solutions that generate trust.
Comprehensive Solution:
Live Leak Repair Under Extreme Conditions
We guarantee operational continuity by eliminating active leaks. A clear success case was the safe containment of a diesel leak under critical pressure and temperature conditions (2,320 PSI and 810°F), using a custom-designed injectable mechanical clamp.
Our specialized service covers a full turnkey solution: from dimensional technical survey and design engineering, to final fabrication and injection for a definitive live seal — protecting the integrity of your assets without stopping your production.
