Flange Gaskets - Pumps, Valves, Piping and Fittings
Flange gaskets used on marine pumps, valves, piping and fittings to provide a leak-tight seal between mating flanges. Selection depends on fluid, temperature, pressure, flange standard, facing and gasket material.
ProShipWorks provides end-to-end support to source and supply Flange Gaskets for marine vessels, ship operators, industrial facilities, maintenance teams and procurement departments.

Standards, Certifications & Class Approval
Review the available standards and approval information relevant to the product. Actual certification, material traceability, inspection and classification requirements depend on the product type, intended application and purchasing specification.
| Applicable Standards & Certification | Common standards include ASME B16.20 for metallic and spiral-wound gaskets, ASME B16.21 for nonmetallic flat gaskets, EN 1514, DIN 2690 and applicable JIS flange standards. Material compatibility and service limits must be confirmed from the manufacturer. |
|---|---|
| Class Approval | Classification approval is product-, material- and application-specific. Marine installations may require acceptance or type approval from DNV, ABS, Lloyd's Register, Bureau Veritas or ClassNK, particularly for critical piping systems. |
Installation, Maintenance & Safety Information
| Installation Notes | Confirm flange standard, nominal size, pressure class, facing, gasket material and service compatibility. Clean and inspect flange faces, align piping without forcing, install a new gasket, and tighten bolts in a calibrated cross-pattern to the specified torque. Do not reuse compressed or damaged gaskets. |
|---|---|
| Maintenance Tips | Inspect accessible flange joints for leakage, corrosion, vibration and bolt loosening during planned maintenance. Check gasket condition whenever a flange is opened and replace it if compressed, cracked, contaminated or damaged. Retightening should follow the equipment maker's procedure. |
| Safety Notes | Isolate, depressurize, drain and cool the system before opening any flange. Verify absence of hazardous fluid or pressure, use suitable personal protective equipment, and confirm gasket chemical and temperature compatibility. Never use a gasket outside its rated service conditions. |
