Pressure Vessel Services

Leading the industry in pressure vessel services and life extension

WSI leads the industry in extending the life of pressure equipment with advanced engineering solutions that increase product yields and enhance plant operational reliability. Utilizing our Unifuse® technology, we specialize in pressure vessel services, including repairing and upgrading critical pressure vessels such as distillation units, reactors, coke drums, digesters, and high-pressure separators.

Addressing critical pressure vessel challenges with automated welding

The integrity of pressure vessels is crucial in process industries, where wall thinning, pitting, cracking, and corrosion/erosion pose significant challenges. WSI tackles these issues with our pressure vessel automated welding technology, providing quick, lasting repairs or upgrades.

Permanent pressure vessel repair solutions with Unifuse technology

Our patented Unifuse technology is recognized in process industries for effectively mitigating corrosion in vessel applications. This technology uses a fully fused weld metal deposit of corrosion-resistant alloys applied with proprietary automated welding systems. These systems ensure exceptional weld quality with minimal heat input, allowing the applied thickness to contribute to pressure boundary calculations. Unifuse is preferred among major refiners, delivering substantial ROI across thousands of applications.

Advanced welding machines for improved efficiency

WSI’s state-of-the-art NG4 weld machines feature proprietary design and closed-loop integral custom waveform technology, significantly improving arc time and efficiency while advancing project schedules. Our permanent repair solutions extend the operational lifespan of a wide range of pressure vessels, ensuring effective vessel corrosion mitigation.

Excellence in ASME-certified pressure vessels

WSI South America’s ASME-certified pressure vessels adhere to global quality standards for design and manufacturing. These vessels safely contain liquids, vapors, or gases under high pressures, making them suitable for diverse industrial applications.

Manufactured from carbon or stainless steel, our vessels offer customizable options to meet specific needs such as corrosion resistance, temperature tolerance, and pressure requirements. Our manufacturing processes comply with ASME construction codes and optimize your construction project by executing internal overlays with special alloys to extend vessel service life and enhance performance.

Choosing WSI for your pressure vessel services ensures reliable pressure vessel repair, superior pressure vessel welding, and effective pressure vessel corrosion mitigation.
