API 598
API standard for valve testing and inspection - shell (body) pressure test, seat leakage test, and backseat test. Defines acceptance criteria for leakage rates during hydrostatic and pneumatic tests. Most industrial valves are tested to API 598.
Applicable Standards
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.
Industrial Valves - Pressure Testing of Metallic Valves
ISO 5208 is the international standard for pressure testing of metallic valves.
Frequently Asked Questions
What does API 598 cover?
API standard for valve testing and inspection - shell (body) pressure test, seat leakage test, and backseat test. Defines acceptance criteria for leakage rates during hydrostatic and pneumatic tests. Most industrial valves are tested to API 598.
Which valves require compliance with API 598?
API 598 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 598-compliant test certificates.
Does Vajra Industrial Solutions supply API 598-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.
