4.4檢查范圍采購訂單中可規(guī)定檢查范圍，除非另有說明，否則檢查范圍將限于以下內(nèi)容。a） 在組裝期間檢查閥門，以確保符合采購訂單的規(guī)范。檢查可能包括使用指定的無損檢測方法。b） 見證要求和規(guī)定的可選壓力測試和檢查。版權(quán)所有美國石油學(xué)會由IHS根據(jù)API許可證提供，許可證持有人=阿爾伯塔大學(xué)/5966844001，用戶=sam，albert未經(jīng)IHS許可，不得復(fù)制或聯(lián)網(wǎng)，不得轉(zhuǎn)售，2013年6月28日16:13:35 MDT 4 API標(biāo)準(zhǔn)598 c）見證任何補(bǔ)充檢查（見4.6）。d） 審查工廠記錄和無損檢測記錄（包括規(guī)定的射線照片）。4.5檢查4.5.1閥門制造商應(yīng)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(yīng)檢查每個(gè)閥門，以確保其符合本標(biāo)準(zhǔn)和參考采購規(guī)范（如API 599）。4.5.3所有檢查應(yīng)按照符合適用標(biāo)準(zhǔn)的書面程序進(jìn)行。4.6補(bǔ)充檢查只有在采購訂單中規(guī)定的情況下，并且只有在規(guī)定的范圍內(nèi)，才需要補(bǔ)充檢查。鋼鑄件或鍛件的磁粉、射線照相、液體滲透和超聲波檢查應(yīng)符合ASME B16.34第8部分的要求，或買方自己的程序和驗(yàn)收標(biāo)準(zhǔn)（如有規(guī)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.
