前綴NPS的使用適用于帶有等級名稱(chēng)的鋼制閥門(mén)。3.8外殼試驗超過(guò)閥門(mén)冷工作壓力CWP額定值的壓力試驗，目的是驗證閥門(mén)承壓結構的穩固性和強度。3.9目視可檢測泄漏—閥門(mén)壓力試驗期間的泄漏，通過(guò)或通過(guò)正常視覺(jué)驗證的壓力邊界或關(guān)閉構件。4檢查、檢查和補充檢查4.1閥門(mén)制造商工廠(chǎng)的檢查買(mǎi)方應在采購訂單中說(shuō)明其在閥門(mén)制造商工廠(chǎng)檢查閥門(mén)和見(jiàn)證試驗和檢查的意圖。每當訂單上的工作正在進(jìn)行時(shí)，買(mǎi)方檢驗員應能自由進(jìn)入與閥門(mén)制造相關(guān)的設備的任何部分。4.2閥門(mén)制造商工廠(chǎng)外的檢查當閥門(mén)采購商規定檢查將包括在閥門(mén)制造商工廠(chǎng)以外的地方制造的殼體部件時(shí)，這些部件應在其制造地點(diǎn)接受閥門(mén)采購商的檢查。4.3檢查通知當規定由買(mǎi)方進(jìn)行檢查時(shí)，閥門(mén)制造商應在要求的閥門(mén)測試和任何規定的補充檢查或檢查前五個(gè)工作日通知買(mǎi)方，并注明采購訂單中規定的通知。如果需要檢查，閥門(mén)制造商還應提前五個(gè)工作日向買(mǎi)方發(fā)出通知，說(shuō)明在閥門(mén)制造商工廠(chǎng)外制造的殼體部件可在何處和何時(shí)進(jìn)行檢查。
4.4檢查范圍采購訂單中可規定檢查范圍，除非另有說(shuō)明，否則檢查范圍將限于以下內容。a） 在組裝期間檢查閥門(mén)，以確保符合采購訂單的規范。檢查可能包括使用指定的無(wú)損檢測方法。b） 見(jiàn)證要求和規定的可選壓力測試和檢查。版權所有美國石油學(xué)會(huì )由IHS根據API許可證提供，許可證持有人=阿爾伯塔大學(xué)/5966844001，用戶(hù)=sam，albert未經(jīng)IHS許可，不得復制或聯(lián)網(wǎng)，不得轉售，2013年6月28日16:13:35 MDT 4 API標準598 c）見(jiàn)證任何補充檢查（見(jiàn)4.6）。d） 審查工廠(chǎng)記錄和無(wú)損檢測記錄（包括規定的射線(xiàn)照片）。4.5檢查4.5.1閥門(mén)制造商應對閥體、閥蓋、蓋子和關(guān)閉元件的所有鑄件進(jìn)行目視檢查，以確保符合MSS SP-55。4.5.2應檢查每個(gè)閥門(mén)，以確保其符合本標準和參考采購規范（如API 599）。4.5.3所有檢查應按照符合適用標準的書(shū)面程序進(jìn)行。4.6補充檢查只有在采購訂單中規定的情況下，并且只有在規定的范圍內，才需要補充檢查。鋼鑄件或鍛件的磁粉、射線(xiàn)照相、液體滲透和超聲波檢查應符合ASME B16.34第8部分的要求，或買(mǎi)方自己的程序和驗收標準（如有規定）。
The use of the prefix NPS applies to steel valves with grade designations. 3.8 The shell test is a pressure test that exceeds the CWP rating of the valve cold working pressure to verify the stability and strength of the valve pressure bearing structure. 3.9 Visually Detectable Leakage - leakage during valve pressure test, pressure boundary or closure components that pass or pass normal visual verification. 4 Inspection, inspection and supplementary inspection 4.1 Inspection at the valve manufacturer's factory The Buyer shall state in the purchase order its intention to inspect the valve and witness the test and inspection at the valve manufacturer's factory. Whenever the work on the order is in progress, the Buyer's inspectors shall have free access to any part of the equipment related to valve manufacturing. 4.2 Inspection outside the valve manufacturer's factory When the valve purchaser specifies that the inspection will include the shell components manufactured outside the valve manufacturer's factory, these components shall be inspected by the valve purchaser at their manufacturing location. 4.3 Notice of Inspection When the inspection is specified by the Buyer, the valve manufacturer shall notify the Buyer five working days before the required valve test and any specified supplementary inspection or inspection, and indicate the notice specified in the purchase order. If inspection is required, the valve manufacturer shall also notify the Buyer five working days in advance to specify where and when the shell components manufactured outside the valve manufacturer's factory can be inspected.
4.4 Scope of inspection The scope of inspection can be specified in the purchase order. Unless otherwise specified, the scope of inspection will be limited to the following. a) Inspect the valve during assembly to ensure compliance with the purchase order specifications. Inspections may include the use of specified non-destructive testing methods. b) Witness optional pressure tests and inspections as required and specified.
