A Super Duplex S32760 orifice flange is a pair of weld neck or slip-on flanges with pressure taps that hold an orifice plate, made from Super Duplex S32760 to ASTM A182 F55. Orifice flanges are used for flow measurement. Each flange has two ½" NPT pressure-tap holes, and jack screws help separate the pair to change the plate.

FOB / CIF · Nhava Sheva (JNPT), MumbaiSuper Duplex S32760 Orifice Flange — questions buyers ask
Why is the minimum class 300 for orifice flanges?
ASME B16.36 starts at Class 300 so the flange is thick enough to drill the pressure taps radially.
Which standard covers Super Duplex S32760 orifice flanges?
The material is ASTM A182 F55; dimensions follow ASME B16.36. Always state both on your purchase order, with the edition if your project specifies one.
What decides the price of a Super Duplex S32760 orifice flange?
The alloy price, the size and pressure class, quantity, and the testing and documents required. Send your list and we quote the same working day.
Can you supply Super Duplex S32760 orifice flanges to NACE MR0175?
Yes. Super Duplex S32760 is listed in NACE MR0175 / ISO 15156-3 within its limits; state NACE compliance on the order and it is confirmed on the certificate.
What documents do you supply?
EN 10204 3.1 mill certificates as standard, 3.2 with third-party inspection on request, plus dimensional and PMI reports.
