Introduction

Analysis of the core content of the standard

Elements	SY/T 7612 requirements	API 17 series comparison	Implementation points
Component classification	Consistent with API 17A	Directly reference the API classification system	A component identifier management system needs to be established
FMA process	Appendix B provides a standardized template	More detailed than API 17N	Failure mechanism analysis needs to be included
PQS document	47 types of component templates (Appendix C)	No corresponding standardized template	Need to be connected with the supplier's BOM system

Use Subsea ball valve as a case study:

Failure mode identification: Need to analyze 8 types of modes such as corrosion and sealing failure
Acceptance criteria: Differentiated according to water depth level (such as 1500m/3000m)
Test method: Refer to the composite requirements of API 6A and API 17D

Document integration: It is recommended to implement FMA and FMECA analysis in conjunction
Digital application: Establish a PQS electronic database and associate BOM numbers and drawings
Supplier management: Require suppliers to submit certification documents according to the template in Appendix C

Main improvements of this standard compared with the 2010 version:

Added identification requirements for 5 types of equipment including multiphase flowmeter
Introduced TRL (Technology Readiness Level) level assessment
Strengthen the connection with reliability management of API RP 17N
