Seal Service Centre

Mechanical Seals are critical to maintaining safe and reliable running of vital process equipment. From complex refining techniques to everyday water handling, Mechanical Seals are considered state-of-the-art equipment, and designed to seal off any type of rotating equipment. Mechanical Seals safely contain product that can be expensive, hazardous or flammable.

Petrotec, in association with Flowserve, has initially established the mechanical seal repair facility back in 2006. Strategically located in street 39, Salwa Industrial Area, the facility incorporate a fast track workshop and fully trained and Flowserve certified engineers and technicians, offering refurbishment, repair and static pressure testing of mechanical wet seals plus a variety of asset management and reliability optimization services.

In 2019, in partnership with Flowserve, Petrotec has expanded this facility by incorporating a dry gas seal repair and testing workshop. Petrotec can now offer the refurbishment and dynamic testing of compressor seals. Our achievements include successful seal repair agreements with many key oil and gas companies in Qatar for several years.
