High Temperature Gaskets (HTG)

Lamons high temperature gaskets represent the ultimate solution for industrial bolted joints that are exposed to extreme temperature. The HTG design combines the superior sealing performance of a premium oxidation inhibited grade flexible graphite with an exceptional oxidation barrier in mica/phyllosilicate. The combination of these two sealing materials allows the user to eliminate the effects of oxidation at extreme temperatures. Lamons HTG family of products are the most stable and impermeable gasket materials available for extreme temperatures. The overall effective rating of the HTG configuration can go to a MAX of 1500°F.

WRI-HTG

The labyrinth design of the spiral wound provides for enhanced oxidation protection. While Inconel X-750 is commonly selected as the winding metal, any alloy can be selected.

Kammpro-HTG

The Kammpro-HTG is recognized as a problem solver for heat exchangers, large vessels and equipment that experience high operating temperature. Kammpro-HTG represents the best technology available in regards to torque retention, load bearing characteristics and seal ability at elevated temperatures.

DEFENDER™ RG Sealing Gasket

Patent Pending

All piping gaskets are designed to operate at their optimum on flange faces that are clean, free from scratches and indentations, flat, not distorted and have a gramophone surface finish between 125µ.ins to 250µ.ins. (3.2µ.M to 6.3µ.M).

Flange faces which have been subjected to crevice type corrosion attack at, or around, the inner portion of the flange sealing faces can occur over a period of time. In many field applications, the flange surface condition cannot be assessed until the bolted connection has been decommissioned and an inspection has determined the suitability of the flanges to accept the same type of gasket that was initially installed.

Depending on the extent of the flange face damage, the corroded surface may have extended onto the surface where gasket sealing element is seated and simply installing another gasket offers no guarantee the connection will remain tight and leak-free once the flange is commissioned back into service.

An assessment as to the suitability of the flange surfaces has to be made in real-time with several options available:

• Rebuild and machine the flange surface to a suitable condition.
• Rebuild and repair the flange using an epoxy based composite material.
• Replace the damaged flanges.
• Use the same gasket and hope for the best

The Defender™ RG Sealing Gasket has been designed to offer a tight and high integrity sealing solution for use on flange faces that have been subjected to erosion, corrosion, chemical attack and abrasion without having to modify or re-work the flange faces.

General Features
