Ukuhlola: Ngokuvamile, amapayipi ensimbi okuthutha uketshezi kufanele ahlaziywe ukwakheka kwamakhemikhali, ukuhlolwa okuqinile, ukuhlolwa kokucaba kanye nokuhlolwa komfutho wamanzi. Ngaphezu kokuhlolwa okufanele kwenziwe kumapayipi ensimbi okuthutha uketshezi, amapayipi ensimbi e-GB5310, GB6479 kanye ne-GB9948 nawo ayadingeka ukuze ahlolwe ukunwetshwa kanye nokuhlolwa komthelela; izidingo zokuhlolwa kokukhiqiza kulawa mapayipi ensimbi amathathu aqinile. Izinga le-GB6479 liphinde lenze izidingo ezikhethekile zokuqina komthelela wezinga lokushisa eliphansi kwezinto. Ngaphezu kwezidingo ezijwayelekile zokuhlolwa kwamapayipi ensimbi okuthutha uketshezi, amapayipi ensimbi we-GB3087 ejwayelekile nawo ayadingeka ukuze ahlolwe okugoba okubandayo. Ngaphezu kwezidingo ezijwayelekile zokuhlolwa kwamapayipi ensimbi okuthutha uketshezi, amapayipi ensimbi e-GB/T8163 ejwayelekile adingeka ukuthi ahlolwe ukunwetshwa kanye nokuhlolwa kokugoba okubandayo ngokwesivumelwano. Izidingo zokukhiqiza zala mapayipi amabili aziqinile njengalawa amathathu okuqala. Ukukhiqiza: Amapayipi ensimbi wezinga le-GB/T/8163 kanye ne-GB3087 ancibilikiswa kakhulu yisithando somlilo esivulekile noma isiguquli, futhi izingxenye zawo zokungcola kanye nokukhubazeka kwangaphakathi kungaphezulu kakhulu. I-GB9948 incibilikiswa kakhulu yisithando somlilo sikagesi. Iningi labo lingeze inqubo yokucwenga ngaphandle kwesithando somlilo, futhi ukubunjwa nokukhubazeka kwangaphakathi kuncane kakhulu. Izindinganiso ze-GB6479 kanye ne-GB5310 ngokwazo zisho izimfuneko zokucwengisisa ngaphandle kwesithando somlilo, ngezingxenye zokungcola okuncane kanye namaphutha angaphakathi, kanye nekhwalithi yezinto ezibonakalayo eziphezulu kakhulu. Amazinga ekhwalithi yokukhiqiza yezindinganiso zamapayipi ensimbi angenhla alandelana ukusuka phansi ukuya phezulu: GB/T8163
(II) Amapayipi ensimbi angenamthungo aphansi Emishinini yokukhiqiza ye-petrochemical, insimbi evame ukusetshenziswa i-chromium-molybdenum kanye namazinga epayipi lensimbi angenamthungo e-chromium-molybdenum-vanadium angu-GB9948 "amapayipi ensimbi angenamthungo wokuqhekeka kwe-petroleum" GB6479 "Amapayipi ensimbi angenasici angu-5 amapayipi angu-5 amapayipi e-GB angenamthungo" amapayipi ensimbi angenamthungo we-GB ama-boilers anengcindezi ephezulu" I-GB9948 iqukethe amamaki ensimbi e-chromium-molybdenum: 12CrMo, 15CrMo, 1Cr2Mo, 1Cr5Mo, njll. I-GB6479 iqukethe amamaki ensimbi e-chromium-molybdenum: 12CrMo, 15CrMo, 1CrMo5, njll. insimbi ye-chromium-molybdenum kanye ne-chromium-molybdenum-vanadium metal material amabanga: 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12Cr1MoVG, njll. Phakathi kwazo, i-GB9948 isetshenziswa kakhulu njengezimo zokukhetha, kanye nezimo zokukhetha.
