求助关于阀门技术规范的几个术语的翻译? For CS ball valve with trim material of DSS or SDSS or Alloy 825 / 625 construction, the seal pocket of static/dynamic lip seal or chevron seal shall be with Alloy 625 weld overlay in accordance with MESC SPE 77/313. If vendor is unable to carry out weld overlay on the seal pocket areas in the smaller size of valve (like 2 inch and below), the valve body/bonnet shall be supplied with the same material of trim. 小弟想问一下这里面的 seal pocket 和 seal pocket area 是什么意思啊?查看更多3个回答 . 4人已关注
