FOB / CIF · Nhava Sheva (JNPT), MumbaiInconel 600 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 Inconel 600 couplings?
The material is ASTM B564; 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 Inconel 600 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.
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.
