Haihao Group Ships P285NH Threaded RF Flanges to Singapore Client

Haihao Group has completed inspection and shipment of P285NH threaded RF flanges for a Singapore industrial piping project. This batch of P285NH threaded RF flanges follows EN 1092-1 at PN40 rating, combining multiple threaded configurations including BSPP, NPTF and ISO 7-1 BSPT threads, alongside one plain RF plate flange.

These P285NH threaded RF flanges cover varied reducing sizes: DN25×15, DN20×15, DN25×20, DN40×20 and 1.5″×0.5″, plus standard DN15 and 1″ plate flanges. Every P285NH threaded RF flange receives a clear varnish coating to shield the steel surface from moisture during sea transit and site storage in Singapore’s humid climate.

The mix of thread types gives the contractor flexibility to connect to different instrument and branch piping ends. Each P285NH threaded RF flange is dimensionally checked, with thread profile and raised face sealing surface verified per EN 1092-1. P285NH is a normalized pressure vessel steel, chosen for stable mechanical properties and reliable performance under PN40 working pressure.

Many Singapore process and utility piping layouts require reducing threaded flanges to bridge different pipe sizes without extra adapters. Our workshop handles mixed thread specifications and custom reducing flange dimensions efficiently.
