Above-Ground Storage Tanks

Floating Roof Seal Repair, Replacement, & Installation

Floating Roof Seals

PTS is experienced with the installation, inspection, repair and replacement of floating roof seals for above-ground storage tanks.

Floating roof seals have a variety of designs:

  • Wedge wiper seal

  • Compression plate wiper seal

  • Mechanical shoe seal

  • Double wedge wiper seal

  • Double mechanical shoe seal

  • Mechanical shoe seal with secondary wiper seal

Because tanks are never perfectly round, floating roof seals are used to cover the gap of 7 to 10 inches between the tank shell and floating roof rim. The primary and secondary seals complement each other to provide emission control, safety, and protection from contamination.

With multiple seal inspection crews and a trained rescue team to facilitate in-service seal inspection, our repair technicians have the expertise to troubleshoot faulty seals and locate vapor leaks. Whether your tank seals need patched or replaced, PTS has the skills and knowledge you need to keep your above-ground storage tank airtight.
