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 Relevant standards may include ASME B1.20.1 for NPT threads, ISO 7-1 for pipe threads requiring sealing, ISO 228-1 for non-sealing pipe threads, ASME B16.11 for forged fittings and applicable material standards such as ASTM A182 or ASTM B16.
Class Approval Classification acceptance is application- and material-specific. Fittings may be accepted within class-approved piping systems by DNV, ABS, Lloyd's Register, Bureau Veritas or ClassNK when documented against approved drawings, materials and pressure ratings.

Installation, Maintenance & Safety Information

Installation Notes Verify thread type, size, material compatibility, pressure rating and flow direction before installation. Clean threads, use an approved sealant compatible with the service fluid, avoid cross-threading and tighten to the manufacturer's guidance. Do not mix incompatible thread forms.
Maintenance Tips Inspect periodically for leakage, corrosion, vibration damage and thread deterioration. Retighten only when permitted by the manufacturer. Replace fittings showing cracks, severe corrosion, damaged threads or repeated leakage, and verify integrity after pressure testing.
Safety Notes Isolate, drain and depressurize the system before removal or installation. Use suitable personal protective equipment and approved tools. Confirm chemical, temperature and pressure compatibility, and never exceed the fitting's rated service limits.
