Leak Sealing is the process of sealing leaks while under pressure to avoid costly shutdowns, outages or unscheduled maintenance. Instead of shutting pipeline systems down, dismantling equipment and transporting off site for repair, leaks can be repaired while your plant remains in operation at full pressure and temperature. WALDUBA Engineering, with 35 years' experience in Leak Sealing, offers you a proven service to repair leaks in pipes, flanges, valve glands and almost any other joint.
Shutting down to repair leaks can result in financial loss due to lost production and may cause more leaks on starting up due to pressure and temperature fluctuations.
Leaks of steam, hydrocarbons or toxic chemicals can waste energy, pollute the environment and create a hazard to personnel. Steam leaks can erode steel in days leaving major damage to pipes, flanges and valve spindles. Acid leaks can affect the structural integrity of your plant, quickly reducing steel sections and dissolving concrete. Under pressure leak repairs give all the performance benefits of conventional repairs at a fraction of the cost.
WALDUBA Engineering has successfully sealed many leaks of steam, hydrocarbons, chemicals or gas from cryogenic to 600°C, from vacuum to 35MPa, from flanges, valve glands, bonnets and bodies, pipes, elbows, tees, heat exchangers, pressure vessels and nozzles. Our leak sealing service is available throughout Southern Africa 24 hours a day 7 days a week. You can have service when you want it and when you need it without having to pay in-house staff to be on standby.
