FOB / CIF · Nhava Sheva (JNPT), MumbaiSuper Duplex 2507 Coupling — questions buyers ask
What is a half coupling used for?
It is welded onto a pipe or vessel to create a small threaded or socket-weld branch.
Which standard covers Super Duplex 2507 couplings?
The material is ASTM A182 F53; dimensions follow ASME B16.11. Always state both on your purchase order, with the edition if your project specifies one.
What decides the price of a Super Duplex 2507 coupling?
The alloy price, the size and schedule or class, quantity, and the testing and documents required. Send your list and we quote the same working day.
Can you supply Super Duplex 2507 couplings to NACE MR0175?
Yes. Super Duplex 2507 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.
