DINKONDA GLOBAL Power Plants Special EPDM/NBR Excellent Compression Rebound And Creep Resistance APV Plate Heat Exchanger Sealing Gasket Domestic Substitute Gasket

Product Overview
The APV J/A/Q/TR series sealing gasket is a domestically produced replacement sealing spare part developed and manufactured by DINKONDA GLOBAL based on APV's original factory drawings, sealing cross-sectional dimensions, and rubber physical and chemical indicators. It is fully compatible with the APV J, A, Q, and TR series plate heat plates. The product fully replicates the original factory corner hole size, sealing lip cross-section, positioning buckle, and flow guide area contour, and can directly replace imported original gaskets without the need to modify original components such as heat exchanger plates, clamping plates, and clamping bolts. As the core vulnerable sealing component of plate heat exchangers, it achieves reliable isolation of cold and hot medium flow channels, effectively preventing medium leakage and internal liquid leakage, solving problems such as long delivery time of imported spare parts, high procurement costs, and unstable supply. It is widely used in equipment overhaul, project spare parts reserve, heat exchange system renovation and upgrading, and other scenarios.

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

2. Outer frame main sealing lip edge: It is continuously arranged along the outer edge of the gasket, and the thickness and theoretical 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: a special annular sealing structure for medium through holes, which isolates different medium flow channels, avoids internal cross mixing of hot and cold media, and maintains the same aperture and pressure sealing belt width as the original factory.

4. Strengthening sealing ribs in the diversion area: Strengthening sealing ribs are set up in the medium distribution area, which are closely attached to the diversion pattern of the plate, to improve the sealing reliability of the distribution area, and at the same time enhance the anti tear and anti deformation ability of the gasket body.

5. Plate positioning buckle: The shape and layout of the buckle are perfectly matched with the original plate slot, firmly clamped on the heat exchange plate, and the gasket is not easy to slip or peel off during equipment disassembly and assembly, reducing the difficulty of on-site assembly.

6. Leakage warning groove: Reserve a small amount of medium release groove, and in case of early micro leakage, the medium can overflow along the groove, making it easy for operation and maintenance personnel to promptly troubleshoot and deal with hidden dangers in advance.

7. Multiple rubber substrates can be selected according to the working conditions: EPDM ternary ethylene propylene rubber, NBR nitrile rubber, HNBR hydrogenated nitrile rubber, FKM fluororubber, suitable for various industrial working conditions such as water, steam, oil, corrosive media, etc.

Technical Features
1. Highly compatible with APV J/A/Q/TR original plates
The contour, sealing section, and buckle point of the gasket are all in accordance with the original factory standards, enabling direct replacement of imported gaskets. The original plates and machine frame can continue to be reused, and the equipment does not require any structural modifications.

2. Excellent compression rebound and creep resistance performance
Adopting customized rubber formula, excellent compression permanent deformation control, long-term maintenance of sealing pre tightening force under system pressure fluctuations and alternating cold and hot working conditions, reducing leakage and dripping faults, and extending the service life of gaskets.

3. Multiple materials to choose from, covering complex industrial working conditions
EPDM (Ethylene Propylene Diene Monomer) rubber: resistant to hot water, saturated steam, weak acids and bases, suitable for 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: It has both oil resistance and high temperature resistance characteristics, suitable for high-temperature oil process systems;
FKM fluororubber: With outstanding acid and alkali resistance and organic solvent resistance, it is used in chemical strong corrosion heat exchange processes.

4. High precision integrated vulcanization manufacturing process
High temperature molding of precision molds, uniform thickness of gaskets, no process defects such as bubbles, missing materials, or burrs, uniform pressure on the sealing surface, and stable sealing performance of the entire machine.

5. Advantages of localized spare parts supply
Avoiding the problem of long delivery time for imported spare parts, supporting spot inventory and rapid customized production, with a comprehensive cost-effectiveness better than original imported parts, suitable for power plants, chemical, heating, metallurgy, shipbuilding, food and pharmaceutical enterprises to reserve spare parts in bulk.

6. Convenient on-site maintenance and repair
Snap on positioning installation, easy to assemble and less prone to misalignment, shortens equipment downtime for maintenance; Partial damage supports single piece replacement, reducing operation and maintenance costs.
