Mechanized & Automated Weld Overlay Solutions for corroded pressure vessels

Uddcomb International provides mechanized & automated weld overlay solutions for pressure vessels such as pulp digesters, crude distillation columns, reactors, vis-breakers/vacuum towers and boiler tubes worldwide.

– The ultimate solution for corroded pressure vessels

Corrosion and erosion are major problems for the process industry. In recent years corrosion/erosion has increased after process modifications aimed at conserving energy, controlling pollution and increasing production. After years of operation, the corrosion margin is gone – and something must be done.

THE UDDCOMB METHOD® has been used extensively worldwide for restoring badly corroded and eroded pressure vessels for 30 years.
The results are excellent. Pressure vessels restored by THE UDDCOMB METHOD® show no sign of corrosion or loss of wall thickness.

THE UDDCOMB METHOD® use a unique twin torch technology which can reduce the total welding time of the project by as much as 50%.

A layer of stainless material is overlay welded to the inner surface of the corroded pressure vessel. The welding is done on-site, using specially designed GMAW equipment.
The stainless steel weld overlay has metallurgical bond to the base metal, and has at least the same strength. The stainless layer gives excellent protection against further corrosion and erosion.

Quality is assured by careful base metal preparation and by qualification of the welding procedures. Welding equipment and execution of the work on site are carefully supervised by our experienced staff.
Compared with other renovation systems, overlay welding with THE UDDCOMB METHOD® proves a superior one.
With THE UDDCOMB METHOD® the stainless steel layer of metal becomes homogeneous, giving the pressure vessel added wall thickness and an excellent corrosion/erosion resistance.

Nobody, knows how long a renovated pressure vessel can last. The first projects were executed in 1987 and shows no sign of corrosion. We are convinced that pressure vessels renovated with THE UDDCOMB METHOD® will never need another major renovation again.

That is why we call it the ultimate solution.
