API 6D
The API standard for pipeline and piping valves - gate, globe, check, ball, and plug valves used in oil & gas transmission pipelines. Covers design, materials, dimensions, testing (pressure test, seat leakage, shell test), and marking requirements. Considered the benchmark for oil & gas valve quality.

Frequently Asked Questions
What does API 6D cover?
The API standard for pipeline and piping valves - gate, globe, check, ball, and plug valves used in oil & gas transmission pipelines. Covers design, materials, dimensions, testing (pressure test, seat leakage, shell test), and marking requirements. Considered the benchmark for oil & gas valve quality.
Which valves require compliance with API 6D?
API 6D compliance is typically required for valves used in oil & gas, petrochemical, and industrial process applications where the standard applies. Procurement specifications for EPC projects and operating companies often mandate specific standards as part of the Material Requisition (MR). Vajra Industrial Solutions supplies valves with full certification documentation including API 6D-compliant test certificates.
Does Vajra Industrial Solutions supply API 6D-compliant valves?
Yes. Vajra Industrial Solutions supplies industrial valves with third-party inspection and full documentation packages including material test certificates (MTC/EN 10204 3.1), hydrostatic test reports to the applicable standard, and dimensional inspection records.
