API
American Petroleum Institute. Issues valve standards widely used in oil & gas: API 6D (pipeline valves), API 600 (gate valves), API 602 (small steel gate valves), API 609 (butterfly valves), API 526 (flanged safety relief valves), API 598 (valve testing and inspection).
Applicable Standards
Specification for Pipeline and Piping Valves
API 6D is the most widely cited standard for pipeline and piping valves in the oil and gas industry.
Fire Test for Quarter-Turn Valves and Valves Equipped with Nonmetallic Seats
API 607 is the fire-test standard for quarter-turn valves (ball valves and butterfly valves) and other valves with soft (non-metallic) seats and seals.
Valve Inspection and Testing
API 598 is the universal valve testing and inspection standard, defining acceptable leakage rates (leak classes) for hydrostatic shell tests, seat leakage tests, and backseat tests.
Butterfly Valves: Double-Flanged, Lug- and Wafer-Type
API 609 is the dimensional and performance standard for butterfly valves in petroleum and natural gas service.
Specification for Steel Gate Valves - Flanged and Butt-Welding Ends, Bolted and Pressure-Seal Bonnets
API 600 is the primary design and manufacturing standard for full-opening steel gate valves in sizes NPS 2 and larger with flanged or butt-weld ends and bolted or pressure-seal bonnets.
Frequently Asked Questions
What does API cover?
American Petroleum Institute. Issues valve standards widely used in oil & gas: API 6D (pipeline valves), API 600 (gate valves), API 602 (small steel gate valves), API 609 (butterfly valves), API 526 (flanged safety relief valves), API 598 (valve testing and inspection).
Which valves require compliance with API?
API 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-compliant test certificates.
Does Vajra Industrial Solutions supply API-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.
