关于控制阀采购、选型的若干问题的探讨
点击次数:1971 发布时间:2008-03-06
正确选择控制阀与工艺管道的端面连接形式(环形面连接 / 凸面连接 / 对夹式)。如配备对法兰,要求阀门供货方提供阀门和配对法兰之间的垫片,应在合同技术附件中注明要求和法兰材质、压力等级及法兰接管的管标号。对夹式的控制阀本身如有单法兰,法兰连接孔的载丝螺纹应是公制,假如载毕螺纹为英制,应要求阀门供应方配备连接螺栓。

    控制阀的类型、材质、与管道的连接方式,附件的选择、招标文件的准备、评标、技术合同的签订、安装、维护是一个繁琐复杂的过程,任一环节出现漏洞,均可能影响到控制阀的使用。虽然有各种各样的书籍,标准和软件供设计人员和用户的技术人员参考,一般不会有太大的困难,但是,从工艺设计人员提出工艺参数、准备控制阀的招标文件、发标书、评标、技术澄清、形成评标报告、批准评标报告、技术谈判、签订技术合同,到开箱验货、安装、调试、投入使用,一般要经过相当长的时间,期间稍微一大意就会疏忽或漏掉一项或几项,可能会使工厂造成损失并影响工程进度。本文仅将在安徽淮化集团有限公司数次采购控制阀和使用过程中的一些体会和认识进行了总结,建议采购控制阀应有充足的时间,只要技术条件具备,就应提前进行招标文件的准备、评标、技术澄清、签订技术合同等工作,真正把工作做细做深,少出技术纰漏。至于商务合同的进度,则要根据工程进度及资金情况来决定。
