Technical purchasing support
How Hyupshin turns the specification into a controlled flange order.
ANSI / ASME B16.5 production dimensions
Our technical team compares the requested standard edition and project drawing, then releases the applicable dimensions to production.
Class 150 to Class 2500 depending on type and project requirement
We record the Class, RF, FF or RTJ facing, bore or pipe schedule and tolerance notes on each ASME quotation line.
flange type manufacturing details
Flange type, sealing face, drilling, thickness and machining details are checked together so production and inspection use the same specification.
Certificate and inspection records
Our order file carries the agreed EN 10204 3.1, PED, AD 2000, UKCA, PMI, NDT and third-party inspection scope through to shipment.
