EN1092-1 A105 PN16 Flange Package Shipped to Vietnamese Industrial Project
For process piping systems built to European standards in Vietnam, full sets of matching plate and blank flanges are often required for construction, pressure testing and future isolation. Haihao Group has completed production and shipment of a full range of EN1092-1 A105 PN16 flange for a Vietnamese client, combining Type 01.B1 plate flanges and Type 05.B1 blank flanges covering multiple DN sizes at PN16 pressure rating.

This delivery of EN1092-1 A105 PN16 flange includes two flange types under EN1092-1 specification. The Type 01.B1 plate flanges cover small to large nominal diameters from DN15 up to DN400, all rated PN16 and forged from ASTM A105 carbon steel. These plate flanges are widely used for connecting pipework, valves and instrumentation on general industrial piping circuits. Complementing the plate flanges, the order also includes Type 05.B1 blank flanges in DN100, DN250 and DN400, designed to seal pipeline ends for isolation or hydrotest operations.
All EN1092-1 A105 PN16 flange are forged A105 carbon steel, machined strictly to EN1092-1 dimensional and surface requirements. Each flange undergoes visual inspection and dimensional check on bolt hole layout, thickness and flange face flatness before packing. Consistent machining tolerances ensure proper gasket seating and bolt load distribution during assembly, which helps prevent leakage for PN16 service pressure across long-term operation.
The full size range enables the Vietnamese project team to source all required flanges from one supply batch, simplifying procurement, material traceability and inventory management. Our quality team prepares complete material documentation including material test certificates for every EN1092-1 A105 PN16 flange in this shipment. Additional non-destructive inspection or custom surface treatment can be arranged to meet local project acceptance requirements.
Haihao Group supplies EN standard forged flanges for Southeast Asian industrial and water treatment projects. We can manufacture EN1092-1 A105 PN16 flange in Type 01, Type 05 and many other flange types, across various pressure classes and material grades.
