A dedicated support range for Italian standard flange references, especially UNI plate and weld neck series used in replacement orders, distributor stock and project purchasing.
Typical UNI references include UNI 2253, UNI 2254, UNI 2276, UNI 2277, UNI 2278, UNI 2280, UNI 2281, UNI 2282, UNI 2283, UNI 2284, UNI 6083, UNI 6084, UNI 6088, UNI 6089, UNI 6090, UNI 6091, UNI 6092, UNI 6093, UNI 6094 and UNI 6095.
Our UNI quotation records the exact standard number, PN rating, nominal size, material grade, facing and documentation scope.
Our technical team compares the requested standard edition and project drawing, then releases the applicable dimensions to production.
We record the PN rating, sealing-face form, surface finish and tolerance notes on each PN-rated quotation line.
Flange type, sealing face, drilling, thickness and machining details are checked together so production and inspection use the same specification.
Our order file carries the agreed EN 10204 3.1, PED, AD 2000, UKCA, PMI, NDT and third-party inspection scope through to shipment.
