DINKONDA GLOBAL Power Plants Special Alfa-Laval ACCESSEN AU/AN/AC/AP Series Plate Heat Exchanger Sealing Gasket Domestic Substitute Gasket

Product Overview
ACCESSEN AU/AN/AC/AP series sealing gaskets are domestically produced replacement sealing spare parts for plate heat exchangers, fully compatible with the full range of heat exchange plates from ACCESSEN AU, AN, AC, and AP. The product replicates the original factory hole size, sealing lip cross-section, positioning buckle, and flow guide area contour, and can directly replace the original gasket without the need to modify hardware components such as heat exchanger plates, clamping plates, and clamping bolts. As a core vulnerable component of heat exchangers, gaskets achieve the isolation of cold and hot medium flow channels, effectively preventing medium leakage and internal cross flow, solving the industry pain points of long supply cycles, high procurement costs, and unstable spare parts supply for imported spare parts. They are widely used in equipment maintenance, project spare parts reserve, and heat exchange system renovation and upgrading scenarios.

Structural Composition
1. The gasket is formed by high-temperature molding and integrated vulcanization process, mainly including five structures: the main sealing lip of the outer frame, the annular sealing ring of the corner hole, the reinforcing rib of the flow guide area, the plate positioning buckle, and the leakage warning groove.

2. Outer frame main sealing lip edge: It is continuously distributed along the outer edge of the gasket, and the thickness and compression of the lip edge strictly match the original factory technical parameters. After the equipment is compressed, a continuous sealed barrier is formed to prevent the medium from leaking outward.

3. Corner hole annular sealing ring: The annular sealing structure of the medium circulation channel effectively isolates different medium flow channels, avoids internal mixing of hot and cold media, and maintains the same aperture and sealing pressure band width as the original factory.

4. Reinforcement bars in the diversion area: Sealing reinforcement bars are set up in the medium distribution area, which are attached to the diversion pattern of the plate to ensure the sealing reliability of the distribution area, while improving the anti tear and anti deformation ability of the gasket body.

5. Plate positioning buckle: The shape and layout of the buckle are completely matched with the original plate slot, which can be firmly attached to the heat exchange plate. During the disassembly and assembly process of the equipment, the gasket is not easy to slip or curl off, reducing the difficulty of on-site assembly.

6. Leakage warning groove: Set up a trace medium release groove. When early micro leakage occurs in the seal, the medium can overflow along the groove, making it easy for operation and maintenance personnel to quickly identify the fault point and handle it in advance.

7. Multiple rubber substrates can be selected as needed: EPDM (ethylene propylene diene monomer) rubber, NBR (nitrile rubber), HNBR (hydrogenated nitrile rubber), FKM (fluororubber), covering diverse working conditions such as water, steam, oil, and corrosive media.

Technical Features
1. Fully compatible with ACCESSEN AU/AN/AC/AP original boards
The contour, sealing section, and buckle point of the gasket are all in accordance with the original factory standards, enabling direct replacement of imported original gaskets. The original plates and the entire machine frame continue to be reused, and the equipment does not require any structural modifications.

2. Excellent compression rebound and creep resistance performance
Adopting a customized rubber formula, the compression permanent deformation index is excellent, and it can maintain the sealing preload force for a long time under system pressure fluctuations and temperature fluctuations, reduce leakage and dripping faults, and extend the service life of the gasket.

3. Multi material selection, suitable for complex industrial working conditions
EPDM (Ethylene Propylene Diene Monomer) rubber: resistant to hot water, saturated steam, weak acids and bases, commonly used in heating and heat exchange stations, central air conditioning circulating water systems;
NBR nitrile rubber: resistant to mineral oil and lubricating oil, suitable for engine oil cooling and ordinary heat transfer oil heat exchange conditions;
HNBR hydrogenated nitrile rubber: dual properties of oil and high temperature resistance, suitable for high-temperature oil process systems;
FKM fluororubber: excellent acid and alkali resistance, organic solvent resistance, used in chemical strong corrosion heat exchange processes.

4. High precision integrated vulcanization manufacturing process
Precision molds are molded at high temperatures, with uniform gasket thickness and no process defects such as bubbles, missing materials, or burrs. The sealing surface is uniformly compressed, and the overall sealing performance of the machine is stable and reliable.

5. Advantages of localized spare parts supply
Get rid of the long lead time restrictions on imported spare parts, support spot inventory and rapid customized production, with a comprehensive cost-effectiveness better than original imported parts, suitable for power plants, chemical, heating, metallurgy, and shipbuilding enterprises to reserve spare parts in bulk.

6. Convenient on-site maintenance and repair
Snap on installation structure, simple assembly and positioning, less prone to misalignment, shortening equipment downtime for maintenance; Partial damage can be replaced individually, reducing equipment maintenance investment.
