With decades of industry research and experience to draw from, APServices wants to share with our customers proven sealing solutions to common equipment reliability issues. By sharing these proven solutions with our customers APServices hopes to provide you with not only a solution that has worked, but an explanation for why it worked.

  • Fire Protection Valves

    Some M & K Valves on fire protection systems have an anti-tamper switch depression on the valve stem causing graphite packing to fail if used. Additionally, a weak gland design limits the amount of packing stress that can be used, and typically this amount is less than the recommended stress for graphite packing.

  • Hydrogen Water Cooler Gasket Leak

    A nuclear plant in Illinois experienced a gasket leak from the water side of a hydrogen cooler flange. Existing gasket was a reinforced rubber gasket. The gasket was replaced with a Gore Power Grade gasket that resulted in no leaks.

  • Relay Valve Gasket Leakage on Coolant Injection System

    Flange gaskets on coolant injection relay valve leaked at a Nuclear Power Plant. Original Vegetable Fiber Paper gaskets over-crushed easily and water wicked through the cellulose fibers. The use of Garlock Multi-Swell 3760 prevented leakage in this application.

  • Gasket Blow Out on Exciter Heat Exchanger

    Gasket on Exciter Heat Exchanger blew out at Nuclear Power Plant. Corroded flanges were coated with Econ (epoxy), which created a smooth, uneven sealing surface. The gasket was replaced with Garlock Style 3760 Multi-Swell which worked well in this application.

  • Flange Gasket Leak in High Cycling Heat Exchanger

    A high cycling heat exchanger experienced flange leakage with the use of a kammprofile style gasket. A spiral wound with heat treated Inconel X-750 was recommended for its outstanding ability to recover under harsh cyclic conditions. This unique winding provided the extra resiliency needed to overcome the thermal expansion and contraction of components in a bolted joint.
