WG Seals is Mesa ETP’s premier seal system for floating roofs in above ground storage tanks (ASTs). The WG Seal is the proven and trusted seal system used by the industry’s leading storage terminal owners, refineries, pipelines, and AST contractors in thousands of installations worldwide for over 35 years.

The WG Seal system now features ClipLock^TM, the proprietary fastener-free lock-in-place fabric attachment system that makes installation faster, easier, and safer for the installers and the environment.

• Adaptable to existing or new floating roofs
• Compatible with most stored products including 100% aromatics
• Able to be installed while the tank remains in service (no welding or flame cutting)
• Faster installation compared to other seal systems
• Adaptable to severely out-of-round tanks

DEMONSTRATED TO INSTALL IN HALF THE TIME

In actual storage tank field tests, workers installed the WG shoe seal with ClipLock™ attachment system in about half the time of the conventional seals. This means workers spend less tank time on in-service installations. Plus, there are no small fasteners that discourage the use of required safety gloves.

ClipLock^TM replaces the time-consuming bolt-through system that can compromise fabric integrity. The lock-in-place system features continuous fabric contact, a method that has been shown in laboratory tests to significantly reduce product emissions.
