一公司山西神頭二期2×1000MW機組工程4號機組鍋爐水壓試驗一次性成功

7月30日,山西神頭 “上大壓小”二期2×1000MW機組工程4號機組鍋爐水壓試驗一次成功。62778道受熱面檢測焊口無一泄漏,焊口一次合格率99%以上。

為確保此次鍋爐水壓試驗順利完成,項目部結合現場的實際情況制定了詳細、可操作性強的水壓試驗專項計劃,認真落實公司安全、質量標準化施工要求,并對參加此次鍋爐水壓試驗的人員進行了嚴格的安全和技術交底。

水壓試驗前,項目通過了山西省質量監督站和中國特檢院專家檢查組的監督檢查,均認定#4鍋爐具備水壓試驗條件。此次水壓試驗分別對4號鍋爐一次汽系統、二次汽系統、一次再熱系統、二次再熱系統進行了壓力測試,一次汽系統最高壓力37.25MPa、二次汽系統最高壓力11.4MPa穩壓20分鐘,隨后一次汽系統降壓至工作壓力29.8MPa、二次汽系統降壓至工作壓力7.59MPa穩壓30分鐘,壓力表讀數無變化,試驗系統無壓降。隨后降壓至工作壓力,經建設單位、監理單位、制造單位、施工單位聯合檢查,確認鍋爐受壓元件無滲漏、無明顯變形,試驗系統無壓降,一致認為鍋爐水壓試驗合格。

整個試驗過程中,項目部各級人員齊心協力、配合緊密,上水、升壓、檢查等工作進行有序,項目部的管理和協調組織能力得到了業主及監理的一致好評。鍋爐水壓試驗的一次成功,為實現機組高質量按期投產奠定了堅實基礎。
