HIGH PERFORMANCE FIBER GASKET FOR CHEMICAL AND INDUSTRIAL APPLICATIONS

A New Level of Adaptability Flat gaskets provide a static seal between two flat sealing surfaces and are used in critical applications in numerous industries. They connect valves, fittings, pipes, pumps and flanges, where they are often subjected to aggressive media. Gaskets must be able to form a tight seal by adapting to the sealing surface, while withstanding challenging operating environments. Classic fiber gasket On a sealing surface with a defined level of damage, tests were conducted to compare gasket adaptability at 20 MPa / 2900 psi surface pressure. The difference in thickness between...

FlatSealTM HMF18 Outperforming classic fiber gaskets FlatSealTM HMF18 solves the long-standing issue with classic fiber gaskets by offering a new level of surface adaptability. With a compressibility level of 18%, in accordance with American Society for Testing and Materials (ASTM) Guideline F36J, it performs approximately three times better than conventional gaskets. The innovative HMF18 material compensates reliably for flange unevenness at comparatively low surface pressure levels. Full traceability Outstanding media compatibility Wide-ranging compliance Effective sealing of uneven surfaces...

Effective Flat Sealing FlatSealTM HMF18 is produced using an innovative blend of high-quality aramid fibers, special functional fillers, and Nitrile Butadiene Rubber (NBR) to effectively seal uneven surfaces and provide outstanding leak tightness. Thanks to its optimized material composition and advanced processing technology, the HMF18 compound demonstrates media resistance and mechanical stability under temperature stress. It is also equipped with FlatSeal™ Code Technology, a permanent fingerprint that enables full traceability from the material batch through to the cut gasket. FEATURES & BENEFITS...

Because of its unique raw material concept and advanced processing technology that results in enhanced material flexibility, the FlatSeal™ HMF18 offers reliable sealing, even with minimal or inconsistent surface pressure. Numerous tests have been performed to prove the performance of FlatSeal™ HMF 18. At an internal pressure level of 40 bar / 580 psi, in relation to the surface pressure level, tests show that FlatSeal™ HMF18 is significantly better at preventing leakage than conventional fiber gaskets. Tests performed in accordance to EN 13555 demonstrate that advanced manufacturing technology...

INFLUENCE OF AN INNER EYELET FlatSealTM HMF18 is punched out of a sheet and can be finished with a stainless steel inner eyelet. A unique feature of this highly adaptable gasket is that it achieves similar performance levels both with and without an inner eyelet. The ability to produce both versions with nearly identical performance characteristics, reduces storage and logistics in gasket production and offers potential savings. TEMPERATURE TESTS DEMONSTRATE SUPERIOR RESULTS Testing of FlatSeal™ HMF18 focused on determining how the gasket deforms when application temperatures increase. Temperature...

FlatSeal™ HMF18 - Reliable sealing for pumps A pump is a mechanical device that moves liquids from one place to another. They are used all over the world, in different industries and for numerous applications. Sealing solutions, including flat gaskets are responsible for preventing leakage within the pump and where the pump is connected to other components and pipes. In the chemical processing industry, high demands are placed on pumps. They must effectively manage corrosive or aggressive fluids, while ensuring a safe environment and productive manufacturing process. In large pumps, flat gaskets...

FlatSealTM Code Technology Ensuring the highest quality every step of the way Using a state-of-the-art calendaring process, HMF FlatSeal™ gaskets are manufactured with the highest quality raw materials. Every batch of material must match precise specifications and is subject to rigorous inspection to ensure that only approved materials are used in production. To guarantee consistent high quality at all steps, a process control system monitors and controls the preparation of formulations, their blending operation, and the calendaring process that forms the material sheet from which a FlatSeal™...

Recommended temperature range: Recommended pressure range: From high vacuum to a maximum of 125 bar / 1800 psi. The temperature and pressure recommendations in the graphs apply to gaskets 2.0 mm/0.08 inch thick that are used with raised face flanges. Higher stresses are possible when thinner gaskets are used. The recommendations are based on material characteristics and installation conditions. The information provided should therefore be considered cautious estimates rather than specific operational limits.
