• NACE MR0175 / ISO 15156 (sour-service)

How to order

Confirm (a) line pressure rating and pressure class, (b) inlet and outlet end-connection sizes / styles, (c) service class (sour vs standard), (d) bore preference (full vs reduced port), and (e) any temperature, fugitive-emissions, or fire-safe certification requirements. Indus quotes ex-Dubai with full mill test reports, API monogram traceability where applicable, and pre-shipment hydrostatic / shell test certificates.

Companion products

Pair with matched-pressure check valves, plug valves, and flow-iron unions of the same end-connection family. For wellhead service, also specify gate valves and surface safety valves of the equivalent API 6A pressure class. For frac applications, the 1502, 602, and 206 Weco unions are the most common matched standards.
