Four-layer composite structure design: the outer layer is an SAE 304 stainless steel (thickness 0.5mm) pressure-resistant support layer, the middle layer is a sandwich of graphite + ceramic fibre (with a temperature resistance of 1200°C), and the inner layer is a nickel-plated copper foil (thickness 0.2mm) to enhance the sealing surface performance. Compared with ordinary single-layer gaskets, creep resistance is improved by 70%, suitable for the turbocharging system high temperature environment (peak temperature 800°C).

Surface phosphating treatment provides a salt spray corrosion resistance of 2000 hours (ASTM B117 standard), making it suitable for marine engineering, mining and other high humidity, high salt spray conditions.

The edge adopts a wave-shaped elastic structure, which can compensate for the micro-deformation of the flange surface caused by thermal expansion and contraction (deformation ≤ 0.02mm). It maintains sealing stability within the pressure fluctuation range from 0 to 40MPa, and reduces the risk of sealing surface cracking due to sudden pressure changes.

Generator sets: adapted to KTA38-G5 diesel generator sets, reducing exhaust gas leakage at the connection between the turbocharger and the exhaust manifold, and safeguarding power generation efficiency (fuel consumption reduced by 1.2% under 98% load).

Construction machinery: used in mining dump trucks with QSK38 engines, it can withstand the sudden temperature changes in the range from - 30°C to 800°C caused by frequent starts and stops. Its sealing life reaches 5,000 hours, which is three times longer than that of ordinary gaskets.

Marine power: matched with KTA38-M marine engine, it has passed IP68 waterproof and dustproof certification, adapting to the wet deck environment and high-frequency vibration working conditions.

Economic optimisation: By extending the replacement cycle to 2 years or 8,000 hours, the average annual maintenance cost of a single machine is reduced by about 18,000 yuan (based on an annual operation of 4,000 hours).

Intelligent O&M compatibility: Original factory data is pre-loaded into the Cummins Insite diagnostic system, which monitors the seal surface temperature and pressure curve in real time, with an accuracy rate of 95% or higher for triggering the early warning code SPN 5278-18 (seal failure).

Through material innovation, structural simulation and extreme environment verification, the 3175517 flange gasket redefines the sealing reliability of high-load power systems, providing 'zero leakage' protection for Cummins core models.
