Velan的VEL-QCI-955质量工程
（API 600/ISO 10434）
VELAN’S VEL-QCI-955
PROGRAM (API 600/ISO 10434)
Velan的VEL-QCI-955质量工程的实行，为压力壳体铸件设置质量控制标准，确保Velan的铸件在质量上保持一致。
The Velan VEL-QCI-955 Program was implemented
to set the quality control standards for pressure boundary castings, and
to ensure a consistent supply of quality castings to Velan.
- X-射线抽样检验认证过程
X-Ray Sample (pattern) Approval Process;
- X-射线监控程序
X-Ray Monitoring Program;
- 铸件监控程序
Casting Monitoring Program.
试样铸件
SAMPLE CASTINGS
在铸件交付到生产线之前，Velan的NDE三级检察员要对所有铸件进行鉴定，根据B16.34的有关标准对所提交的X射线底片（覆盖率100%）进行认证和核准。
Before castings are released for production, the
Velan NDE Inspector Level III, evaluates and approves the submitted x-ray
films (100% coverage) as per B16.34 acceptance standard.
X射线监控
X-RAY MONITORING:
我们要求对于每个供应商每半年进行一次随机X射线监控，并根据B16.34的规定在通径和数量上进行随机抽样和X射线检测。
Random x-ray monitoring requires that castings
taken every six months from each vendor, randomly by size and quantity
sets and x-rayed per B16.34 requirement.
前工程模型导入Magmasoft®铸
件模拟程序。
Pro-Engineering model imported into
Magmasoft® casting simulation program.
如果铸件没有满足X射线的B16.34标准的要求，Velan的高级冶金专家将发布纠正措施，要求供应商改正，包括改正的详细方法建议和重新进行X射线检测。
If casting fails to meet the x-ray requirements
of B16.34, Velan’s Senior Metallurgist will issue a corrective action
request to the vendor, including recommendations for detailed methoding
change and re-x-ray. |

铸件监控：
CASTING MONITORING:
水利测试出现泄漏，多孔，包含杂质，在X射线或机加工过程出现收缩现象的铸件都被拒收，并记录在计算机系统内，作为每个供应商的统计控制资料之一。
Rejected castings due to defects such as
hydro-test leakage, porosity, inclusions, shrinkage indication discovered
by x-ray or machining, are entered into the computer, as part of
the statistical control of each vendor.

我们与铸造工程师和阀门设计师一起努力，坚持不懈地改进铸件的内在完整性，作为基本要求，使铸件质量达到X射线II级以上水平。
Working together with foundry engineers
and our designers, we continue improving the internal integrity
of castings, to X-Ray Level II or better as a general standard. |
