本技巧旨在帮助工厂工程师采购高质量的铸造不锈钢泵和阀门，尤其是用于关键服务的大尺寸泵和阀门，如果出现故障，可能会造成不可接受的安全或生产问题。这些信息也有助于审查和采购纸浆和造纸厂中不太关键应用的泵和阀门以及其他铸造部件和设备。

This TIP is intended to assist mill engineers in procurement of high-quality cast stainless steel pumps and valves, especially those of large size intended for critical services, where failure would pose unacceptable safety or production problems. The information is also useful in reviews and procurement of pumps and valves for less critical applications and other cast components and equipment in pulp and paper mills.
