At Uddcomb, our engineering team boasts extensive experience and specializes in delivering top-notch solutions tailored to our clients’ unique needs. We’re not just engineers – we are problem solvers, innovators, and partners in your success.
At Uddcomb, we take a detailed approach to repairs and upgrades, ensuring optimal performance and longevity of your valuable production assets.
We begin by conducting a comprehensive assessment and evaluating your equipment, assets, and components. This is typically performed during a site inspection. This step allows us to identify any issues or areas for improvement, providing a solid foundation for our repair and refurbishment efforts.
Our unique mechanized grinding technology removes damaged material from the affected areas. This process prepares the surface for subsequent repair and restoration, ensuring thoroughness and precision in our work.
We address defects or damage in the base material by repairing it and removing previous weld defects and cracks. We restore the affected areas to their minimum thickness through advanced weld build-up techniques, ensuring structural integrity and durability.
As part of our enhancement upgrades, we offer corrosion protection solutions tailored to your needs. This involves THE UDDCOMB METHOD, a unique automatic weld overlay technology with corrosion-resistant alloys (CRO) capable of withstanding aggressive process conditions within pressure vessels, providing long-lasting protection against corrosion and degradation.
Quality assurance checks and non-destructive testing methods reinforce our commitment to quality. We employ various NDE/NDT techniques to effectively inspect large surfaces and verify the integrity and reliability of our weld overlays, ensuring compliance with industry standards and regulations.
We maintain open communication with our clients, seeking their input and approval at every stage. Our priority is your satisfaction, and we value your feedback to ensure our solutions meet your expectations.
After completing the corrosion resistant overlay, we finalize the project and deliver the upgraded assets to you. Additionally, we provide ongoing support and maintenance services for other critical components that may require attention, ensuring the continued performance and reliability of your pressure vessels and production assets.
Trust Uddcomb for corrosion protection, welding repairs and refurbishments that increase the performance and extend the lifetime of your assets and pressure vessels. Contact us today to discuss your project requirements and discover how we can help you achieve your goals.
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.
Automated weld overlay of top domes, cylindrical shells, bottom domes, behind the screens is done 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.
