| GB5310 | Ishubhu yensimbi engenamthungo yebhoyila enomfutho ophezulu | 20G njll. | I-medium eshisayo kakhulu yama-boilers anomfutho ophezulu | Ukwanda, umthelela |
| GB6479 | Ipayipi lensimbi elingenamthungo elinomfutho ophezuluimishini yomanyolo | 10,20G,16Mn njll. | Imikhiqizo kawoyela negesi enokushisa komklamo okungu--40～400℃ kanye nokucindezela komklamo okungu-10.0～32.0MPa | Ukwanda, umthelela, ukuqina komthelela wokushisa okuphansi |
| GB/T9711 | Izimo zokulethwa kobuchwepheshe zamapayipi ensimbi embonini kawoyela negesi |
Ukuhlolwa: Ngokuvamile, amapayipi ensimbi okuthuthwa koketshezi kumele ahlolwe ukwakheka kwamakhemikhali, ukuhlolwa kokucindezelwa, ukuhlolwa kokuthamba kanye nokuhlolwa komfutho wamanzi. Ngaphezu kokuhlolwa okumele kwenziwe kumapayipi ensimbi okuthuthwa koketshezi, amapayipi ensimbi e-GB5310, GB6479 kanye ne-GB9948 nawo ayadingeka ukuze kuhlolwe ukunwetshwa kanye nokuhlolwa komthelela; izidingo zokuhlolwa kokukhiqiza zala mapayipi ensimbi amathathu ziqinile. Izinga le-GB6479 liphinde lenze izidingo ezikhethekile zokuqina komthelela ophansi kwezinga lokushisa kwezinto. Ngaphezu kwezidingo zokuhlolwa ezijwayelekile zamapayipi ensimbi okuthuthwa koketshezi, amapayipi ensimbi esezingeni le-GB3087 nawo ayadingeka ukuze kuhlolwe ukugoba okubandayo. Ngaphezu kwezidingo zokuhlolwa ezijwayelekile zamapayipi ensimbi okuthuthwa koketshezi, amapayipi ensimbi esezingeni le-GB/T8163 ayadingeka ukuze kuhlolwe ukunwetshwa kanye nokuhlolwa kokugoba okubandayo ngokwesivumelwano. Izidingo zokukhiqiza zala mapayipi amabili aziqinile njengezintathu zokuqala. Ukukhiqiza: Amapayipi ensimbi ezindinganiso ze-GB/T/8163 kanye ne-GB3087 ancibilikiswa kakhulu yi-open-hearth furnace noma i-converter, futhi izingxenye zawo zokungcola kanye namaphutha angaphakathi kukhulu kakhulu. I-GB9948 incibilikiswa kakhulu yi-furnace kagesi. Iningi labo lengeze inqubo yokucwenga ngaphandle kwesithando somlilo, futhi ukwakheka kanye neziphambeko zangaphakathi zincane kakhulu. Izindinganiso ze-GB6479 kanye ne-GB5310 ngokwazo zibeka izidingo zokucwenga ngaphandle kwesithando somlilo, kanye nezingxenye ezincane kakhulu zokungcola kanye neziphambeko zangaphakathi, kanye nekhwalithi ephezulu kakhulu yezinto zokwakha. Amazinga ekhwalithi yokukhiqiza ezindinganiso zepayipi lensimbi ezingenhla alandelana kusukela phansi kuya phezulu: GB/T8163
(II) Amapayipi ensimbi angenamthungo ensimbi ephansi e-alloy Emishinini yokukhiqiza i-petrochemical, amazinga epayipi lensimbi engenamthungo asetshenziswa kakhulu yi-GB9948 "Amapayipi ensimbi angenamthungo okuqhekeka kwephethiloli" GB6479 "Amapayipi ensimbi angenamthungo aphezulu emishini yomanyolo" GB/T5310 "Amapayipi ensimbi angenamthungo amabhoyila anomfutho ophezulu" GB9948 iqukethe amazinga ezinto zensimbi ze-chromium-molybdenum: 12CrMo, 15CrMo, 1Cr2Mo, 1Cr5Mo, njll. GB6479 iqukethe amazinga ezinto zensimbi ze-chromium-molybdenum: 12CrMo, 15CrMo, 1Cr5Mo, njll. GB/T5310 iqukethe amazinga ezinto zensimbi ze-chromium-molybdenum kanye namazinga ezinto zensimbi ze-chromium-molybdenum-vanadium: 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12Cr1MoVG, njll. Phakathi kwazo, i-GB9948 isetshenziswa kakhulu, futhi izimo zokukhetha zinjengoba zingenhla.
