專(zhuān)業(yè)為石油天然氣、氣體凈化、化工尾氣回收利用、煙氣二氧化碳捕集及利用、化工醫(yī)藥行業(yè)提供工藝技術(shù)、服務(wù)和設(shè)計(jì)
3.3.3 試驗(yàn)過(guò)程和檢驗(yàn)方法
1)施工工藝流程:
氣壓試驗(yàn)臨時(shí)管線(xiàn)、壓力表安裝要求與水壓試驗(yàn)相同,另外在球罐頂部要設(shè)置兩個(gè)或兩個(gè)以上安全閥和緊急放空閥。安全閥必須使用有制造許可證的單位生產(chǎn)的符合技術(shù)標(biāo)準(zhǔn)的產(chǎn)品,且必須經(jīng)校準(zhǔn)合格。安全閥的啟跳壓力定為試驗(yàn)壓力加0.05Mpa;回座壓力定為0.8倍的試驗(yàn)壓力。安全閥安裝在球罐頂部最外緣較為合適的接管上,排放口朝向外側(cè),避免突然的放空操作影響壓力情況觀測(cè)人員的安全。
