1 HTG GASKETING PRODUCT FAMILY High Temperature Sealing Components for Extreme Industrial Applications

2 Extreme Temperature Lamons is the market leader in the manufacture and supply of high quality gasketing components including spiral wounds, soft gaskets, ring joints, CMG gaskets, kammpros, heat exchanger gaskets and fasteners. Lamons is committed to superior sealing products distributed worldwide in conjunction with personal, localized service. Lamons Gasket Company stocks and provides the widest selection of gasketing and bolt materials. Lamons' sealing solutions are utilized in every major industrial market in the world and we are depended upon daily to quickly respond to any customer specification or demand. We meet our customers' requirements of size, pressure, temperature, shape and materials. Lamons HTG Product Family Lamons high temperature gaskets represent the ultimate solution for industrial bolted joints that are exposed to extreme temperature. By combining the superior sealing performance, impermeability and stability of flexible graphite with an exceptional oxidation barrier, Lamons HTG seals represent the best technology available in regards to torque retention and sealability at elevated temperatures. The Lamons HTG concept utilizes a premium super oxidation inhibited flexible graphite that is completely shielded from oxidation by barriers of mica/phyllosilicate. This inhibited flexible graphite is the most oxidation resistant available on the market and like all homogeneous flexible graphite, completely maintains its physical and mechanical properties regardless of temperature exposure. The phyllosilicate barriers consist of Lamons Hi-Temp material which is a mica/phyllosilicate based sealing material that contains a very low content of inorganic binder (less than half of the binder found in vermiculite/phyllosilicate filled sheets). The combination of these two sealing materials allows the user to maintain the stability and impermeability of flexible graphite and 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. Our major manufacturing facilities are in Houston and Hangzhou, Zhejiang near Shanghai, with sales and service facilities located throughout the U.S. and Canada. We also have many licensees and distributors strategically located throughout the world to provide our customers with local service, advanced technical support, and the widest selection of gasket materials ready for immediate delivery. Our locations feature leading technology and state of the art manufacturing facilities capable of producing engineered sealing products to precise custom specifications serving the refining, chemical, power generation, and pulp and paper industries. WRI-HTG spiral wound gasket Lamons SpiraSeal gaskets are manufactured using specially fabricated machinery. They are configured to allow superior resiliency and selfadjustment when compared to conventional gaskets. Lamons offers these gaskets in almost any combination of size, thickness and component material. Kammpro-HTG kammprofile gaskets Lamons Kammpro gaskets are recognized as a problem solver for heat exchangers, large vessels and equipment that experience excessive movement due to thermal expansion. The Kammpro provides one of the tightest seals combined with superior load bearing characteristics.

Higher temperature may be applicable dependent upon internal pressure conditions and media being sealed. Contact Lamons Engineering for assistance.the use of high temperature alloys is recommend for extreme temperatures. HTG designs can be adapted to any style or size Kammpro or Spiral Wound gasket to provide performance and protection in extreme temperatures. Both HTG designs successfully meet the requirements outlined in the modified AP1607 fire test. Test reports available upon request. Lamons Hi-Temp mica/phyllosilicate sheet is available as a cut gasket to perform in extreme temperature applications where metal reinforcement is not required.

4 Know the facts experience the difference. Independent TGA weight loss testing illustrating the amount of binder contained within popular high temperature gasket solutions. Higher binder content corresponds to weight, volume and torque loss Lamons Kammpro HTG after exposure to 1500 F The Flexible graphite maintains all physical and mechanical properties after exposure Thermal cycling test data shows very favorable test results for both Lamons Kammpro HTG and a competitive vermiculite based material at 500 degrees F. Lamons WRI-HTG spiral wound gasket after exposure to 1500 F Maintaining the proven and superior sealing characteristics of flexible graphite creates an ideal high temperature solution the flexible graphite is completely protected from oxidation Thermal Cycling data at 800 degrees F is where the difference is significantly illustrated. Organic binder in the vermiculite based facing is compromised to the point of leakage. The degradation of the binder in the vermiculite facing results in a loss of the ability to tolerate thermal upsets. The Lamons Kammpro HTG maintains the flexible graphite s original resilience and physical properties while protected from oxidizers by the phyllosilicate barriers.

5 Traditional Seal Concepts Most sealing materials are detrimentally affected by extreme temperature exposure. Many competitive products utilize a necessary processing aid consisting of an organic rubber binder where an inorganic material is held in suspension. This low temperature binder begins to degrade, carbonize and embrittle at temperatures as low as 300 F, resulting in a complete loss of physical and mechanical properties at moderate temperatures. This rubber binder is susceptible to chemical attack and degradation even in mildly aggressive services. This degradation inevitably leads to torque loss and leakage. Since the binder is evenly dispersed throughout the sealing material, a complete loss of physical and mechanical properties is experienced when exposed to elevated temperature. The mechanical properties that are characteristic of an effective seal are lost when the rubber binder is subjected to temperature and chemical attack. Popular compressed non-asbestos gasket exposed to 400 F for a duration of four hours. The physical properties of these materials were severely degraded when exposed to a fraction of their rating. The structure turns glass-like and can fracture with slight flexing. While these materials can still maintain functionality in most cases, their ability to compensate for thermal and pressure fluctuations is severely diminished by heat exposure. A vermiculite based compressed sheet material that utilizes aramid fiber and a high content of organic binder is severely affected by temperature and chemical attack. A vermiculite material offers no additional advantage over compressed non-asbestos at elevated temperatures due to the high organic content. Flexible graphite that is unprotected from oxidizers and exposed to the atmosphere will convert to a gas through oxidation. Flexible graphite that is contained within a spiral wound element (left) will degrade at a slower rate than a faced metal core (right) because it is relatively encapsulated. Total oxidation is inevitable unless the flexible graphite is sufficiently protected. A kammprofile with a vermiculite based facing. An exposure to 1500 F for six hours between flanges destroys the rubber binder that holds the vermiculite powder in suspension. Vermiculite filled spiral wound gaskets utilize organic binder as a processing aid for the filler. Elevated temperature degrades the binder and will compromise tightness and sealability.

6 HTG GASKETING PRODUCT FAMILY Lamons WRI-HTG and Kammpro HTG are the most stable gasket designs available for extreme temperatures. The utilization of flexible graphite allows the gasket to maintain torque and tightness through thermal cycling while providing the ultimate fugitive emissions seal. By utilizing a phyllosilicate oxidation shielding, the flexible graphite is able to maintain its integrity and provide freedom from oxidation.
