美国克雷恩阀门的检测措施
Inspection Policy for Crane Valves |
按照API 598的要求，每个美国克雷恩铸钢阀门都经过100%压力测试。如果需要，可提供制造商材料测试报告和检测和测试证书。一些额外的检测和测试措施是：
Every Crane cast steel valve is subjected to a
100% pressure test according to API 598 requirements. Manufacturer’s material
test reports and Inspection and Test Certifications are available upon
request. Some of the additional inspections and tests performed are:
- 按照ASME B16.34附录B标准对阀体和阀盖铸件进行随机放射性检测
Random Radiograph Inspection of Body and Bonnet
Castings to ASME B16.34 Appendix B
- 根据ASTM A-193/A-194标准对紧固件进行随机化学性能和机械性能检测
Random Chemical Composition and Mechanical Properties
Verification of Fasteners to ASTM A-193/A-194
- 阀座环的液体渗透检测
Liquid Penetrate Inspection of Seat Rings
- 根据MSS-SP-55标准对逐渐进行外观检测
Visual Inspection of Casting to MSS-SP-55
- 根据阀门有关标准在原材料进场、加工工艺过程和最后完工等过程中进行的尺寸检测
Receiving, In-Process, and Final Dimensional Inspections
to Relevant Valve Standards
可以按照用户的要求，根据其它评价标准进行检测或测试。
Other inspections or tests can be performed or
evaluation criteria applied when specified by the customer. |
