UDDCOMB’s innovations, technologies and solutions, focus in safety, reliability and protection. Unique technologies that will ensure minimal downtime, and maximum performance of your valuable production assets.
Experience the innovative twin-torch technology of THE UDDCOMB METHOD®, which can reduce welding time by up to 50%. This on-site weld overlay technique uses specialized GMAW equipment to apply a layer of stainless steel or nickel alloy to corroded pressure vessels, ensuring efficient refurbishment and long-term corrosion protection.
For over 30 years, THE UDDCOMB METHOD® has restored badly corroded pressure vessels worldwide, delivering superior results with no signs of corrosion or wall thickness loss. With its proven track record and exceptional durability, it is the ultimate solution for extending the life of pressure vessels.
Discover UDDCOMB OPTICLAD®, the advanced solution for in situ refurbishing, repairing, and corrosion protection of small-bore nozzles. This specialized technology enables internal welding from 45 to 1200 mm, ensuring superior corrosion protection and durability. By applying a precise weld overlay, UDDCOMB OPTICLAD® extends the life of the reactor, digestor, column, heat exchanger, and pressure vessel nozzles, providing a cost-effective alternative to replacement.
Our specialized equipment supports TIG/GTAW, MIG/MAG/GMAW processes, tailored to specific nozzle diameters and quality requirements. UDDCOMB OPTICLAD® reduces shutdown and technical challenges, making it a superior choice for in-situ nozzle refurbishment and corrosion protection.
Introducing UDDCOMB OPTIGAP, our cutting-edge orbital remote-controlled welding technology for narrow gap welding. Designed for diverse applications, this advanced technology ensures optimal metallurgical properties and meets the highest quality standards. UDDCOMB OPTIGAP focuses on minimizing stress and distortion in the heat-affected zone (HAZ), resulting in superior performance.
We collaborate with clients worldwide to develop and customize orbital welding repair concepts, including welding joints, filler metals, and equipment. UDDCOMB OPTIGAP is ideal for critical industries that require high quality and reliability, such as nuclear, energy, oil and gas, petrochemical, pharmaceutical, and process industries. This technology guarantees exceptional performance and long-term durability for pipes, pipe systems, and components in demanding environments.
Bottom domes in pressure vessels like pulp digesters (both continous and batch digesters), impregnation vessels, columns and reactors often suffers from two degrading mechanisms related the actual process parameters. Erosion or Corrosion. Sometimes both degrading mechanisms are present. The Uddcomb techology is developed to solve these degrading issues of components. The Uddcomb technology makes it possible to avoid a very costly, time consuming and technically challenging replacement of a new component and instead being able to repair and refurbish the actual component onsite – anywhere in the world.

A pulp manufacturing plant producing kraft, sulphite/sulfite, or dissolving pulp experiences severe corrosion in its continuous or batch digesters, with deep pitting up to 5 mm. This extensive corrosion necessitates either replacing shell sections or the complete pulp digester alternativly upgrading it with a long-term corrosion protection solution.

The Uddcomb Method is developed for refurbishment and long term corrosion protection of continuous digesters. The method is developed to offer a high quality solution in combination with minimum duration/downtime of the pulp digester. Automated weld overlay of Continous digesters is a typical application where the high production rates of the twin torched Uddcomb method can save several days on critical path/outage time. The Uddcomb Method have been used for long term refurbishments of corroded digesters for 30 years worldwide.

Processrelated corrosion have caused 3mm deep pittings in the stainless steel compound material. All the corroded compound material is removed by Uddcombs unique remote controlled mechanized grinding units. The automated grinding is done prior to the automated overlay welding with the Uddcomb Method. The total preparation time for grinding of the corroded base material was cut with 5 days on critical path. The remote-controlled mechanized grinding units provided also huge HSE improvements of the normal harsh and risky manual grinding environment inside a confined space. The quality of the grinding was also dramatically improved.
A higher alloyed filler material compared to the original design is used due to process changes and in order to get an increased corrosion protection after refurbishment compared to the original design. We offer a life-time extension solution of the pressure vessel where we upgrade and deliver a pressure vessel in a “better than new” condition without having to replace the vessel.
