Ipayipi lensimbi elingenamthungo lenziwa ngaphandle kokushiselwa ngezindlela zokusebenza ezishisayo njengokugoqa okushisayo okunezimbobo. Uma kudingeka, ipayipi elisebenza ngokushisa lingashintshwa libe yipayipi elibandayo ukuze lifinyelele isimo, usayizi kanye nokusebenza okufiselekayo. Njengamanje, ipayipi lensimbi elingenamthungo liyipayipi elisetshenziswa kakhulu kumayunithi okukhiqiza amakhemikhali.

(1)Ipayipi lensimbi engenamthungo yensimbi yekhabhoni 

Ibanga lezinto: 10, 20, 09MnV, 16Mn izinhlobo ezine sezizonke

Okujwayelekile: GB8163 “Ipayipi lensimbi elingenamthungo lokuthuthwa koketshezi”

I-GB/T9711 “Izimo zobuchwepheshe zokulethwa kwamapayipi ensimbi embonini kawoyela negesi yemvelo”

GB6479"Ipayipi lensimbi elingenamthungo elinomfutho ophezulu lemishini yomanyolo"

GB9948“Ipayipi lensimbi elingenamthungo lokuqhekeka kwephethiloli”

GB3087“Amapayipi ensimbi angenamthungo ama-boilers anomfutho ophansi nophakathi”

GB/T5310"Amashubhu ensimbi angenamthungo ama-boilers anomfutho ophezulu"

GB/T8163:

Ibanga lezinto ezibonakalayo: 10, 20,Q345, njll.

Ububanzi bokusetshenziswa: izinga lokushisa eliklanyelwe lingaphansi kuka-350℃, ingcindezi ingaphansi kuka-10MPa uwoyela, uwoyela kanye nendawo yomphakathi

GB6479:

Ibanga lezinto: 10, 20G, 16Mn, njll.

Ububanzi bokusetshenziswa: uwoyela negesi enokushisa komklamo okungu--40 ~ 400℃ kanye nomfutho womklamo ongu-10.0 ~ 32.0MPa

GB9948:

Ibanga lezinto: 10, 20, njll.

Ububanzi bokusetshenziswa: Akufaneleki emicimbini yamapayipi ensimbi e-GB/T8163.

GB3087:

Ibanga lezinto: 10, 20, njll.

Ububanzi bokusetshenziswa: umusi oshisayo kakhulu webhoyila ophansi nophakathi, amanzi abilayo, njll.

GB5310:

Ibanga lezinto: 20G, njll.

Ububanzi besicelo: i-steam medium eshisayo kakhulu yebhoyila enomfutho ophezulu

Ukuhlolwa: Ukuhlaziywa kokwakheka kwamakhemikhali, ukuhlolwa kokuxineka, ukuhlolwa kokuthamba kanye nokuhlolwa komfutho wamanzi kumele kwenziwe epayipini lensimbi elisetshenziselwa ukuthuthwa koketshezi olujwayelekile.

GB5310, GB6479, GB9948Izinhlobo ezintathu zepayipi lensimbi elijwayelekile, ngaphezu kwepayipi lokuthutha uketshezi kumele zihlolwe, kodwa futhi kudingeka ukuthi kwenziwe ukuhlolwa kokuvutha kanye nokuhlolwa komthelela; Izidingo zokuhlolwa kokukhiqiza zalezi zinhlobo ezintathu zamapayipi ensimbi ziqinile impela.

GB6479indinganiso futhi yenza izidingo ezikhethekile zokuqina komthelela ophansi wokushisa kwezinto.

Ipayipi lensimbi elijwayelekile le-GB3087, ngaphezu kwezidingo zokuhlola ezijwayelekile zepayipi lensimbi yokuthutha uketshezi, kodwa futhi lidinga ukuhlolwa kokugoba okubandayo.

Ipayipi lensimbi elijwayelekile le-GB/T8163, ngaphezu kwezidingo zokuhlola ezijwayelekile zepayipi lensimbi elithuthwa ngoketshezi, ngokwezidingo zesivumelwano sokwenza ukuhlolwa kokuvutha kanye nokuhlolwa kokugoba okubandayo. Izidingo zokukhiqiza zalezi zinhlobo ezimbili zamapayipi aziqinile njengezezinhlobo ezintathu zokuqala.

Ukukhiqiza: Ipayipi lensimbi ejwayelekile ye-GB/T/8163 kanye ne-GB3087 isebenzisa ukuncibilikisa isithando somlilo esivulekile noma i-converter, ukungcola kwayo kanye neziphambeko zangaphakathi kukhulu kakhulu.

GB9948ukuncibilikisa isithando sikagesi. Iningi lengeziwe enqubweni yokucwengisisa isithando ngezithako ezimbalwa kanye namaphutha angaphakathi.

GB6479futhiGB5310amazinga ngokwawo achaza izidingo zokucwengisisa ngaphandle kwesithando, kanye nokungcola okuncane kanye nokukhubazeka kwangaphakathi kanye nekhwalithi ephezulu kakhulu yezinto zokwakha.

Izindinganiso eziningana zamapayipi ensimbi ezingenhla zenziwe ngokulandelana kwekhwalithi kusukela phansi kuya phezulu:

GB/T8163＜GB3087＜GB9948＜GB5310＜GB6479

Ukukhetha: ngaphansi kwezimo ezijwayelekile, ipayipi lensimbi elijwayelekile le-GB/T8163 lifanelekela izinga lokushisa lomklamo lingaphansi kuka-350℃, ingcindezi ingaphansi kuka-10.0mpa imikhiqizo kawoyela, uwoyela negesi kanye nezimo zomphakathi eziphakathi nendawo;

Kumikhiqizo kawoyela, uwoyela kanye negesi, lapho izinga lokushisa lomklamo lingaphezu kuka-350℃ noma ingcindezi ingaphezu kuka-10.0mpa, kufanelekile ukukhethaGB9948 or GB6479ipayipi lensimbi elijwayelekile;

GB9948 or GB6479indinganiso kufanele futhi isetshenziswe kumapayipi asebenza eduze kwe-hydrogen noma ezindaweni ezivame ukugqwala ngenxa yokucindezeleka.

Izinga lokushisa eliphansi elijwayelekile (elingaphansi kuka--20℃) kusetshenziswa ipayipi lensimbi yekhabhoni kufanele lisetshenzisweGB6479ejwayelekile, kuphela ecacisa izidingo zokuqina komthelela ophansi wezinto zokwakha.

GB3087 kanyeGB5310Izindinganiso zibekwe ngokukhethekile ezindinganisweni zamapayipi ensimbi ebhoyila. "Imithethonqubo yokuqapha ukuphepha kwamabhoyila" igcizelele ukuthi konke okuxhunywe kumapayipi ebhoyila kungokwasesilinganisweni sokuqapha, ukusetshenziswa kwezinto kanye nezindinganiso kufanele kuhambisane nemithetho yokuphepha kwamabhoyila, ngakho-ke, ibhoyila, isiteshi sikagesi, idivayisi yokushisa kanye ne-petrochemical esetshenziswa epayipini lomusi womphakathi kufanele isetshenziswe (ngokunikezwa kohlelo) yi-GB3087 noma ejwayelekile.GB5310.

Kuyaphawuleka ukuthi ikhwalithi yezindinganiso ezinhle zamapayipi ensimbi, amanani amapayipi ensimbi aphezulu kakhulu, njengeGB9948Intengo yezinto ezibonakalayo ze-GB8163 icishe ibe yi-1/5, ngakho-ke, ekukhetheni amazinga ezinto zepayipi lensimbi, kufanele kucatshangelwe ngokwemibandela yokusetshenziswa, kokubili okuthembekile nokonga. Kufanele futhi kuqashelwe ukuthi amashubhu ensimbi ngokuhambisana ne-GB/T20801 kanye ne-TSGD0001, i-GB3087 kanye ne-GB8163 akufanele asetshenziswe kumapayipi e-GC1 (ngaphandle kokuthi i-ultrasonic ngayinye, ikhwalithi engaphansi kwe-L2.5, ingasetshenziswa kumklamo wamapayipi e-GC1(1) ingcindezi engaphansi kwe-4.0Mpa).

(2) Ipayipi lensimbi elingenamthungo lensimbi ephansi

Ezikhungweni zokukhiqiza i-petrochemical, amazinga asetshenziswa kakhulu epayipi lensimbi engenamthungo yensimbi ye-chromium-molybdenum kanye nensimbi ye-chromium-molybdenum vanadium asetshenziswa kakhulu.

GB9948 “Ipayipi lensimbi elingenamthungo lokuqhekeka kwephethiloli"

GB6479 “Ipayipi lensimbi elingenamthungo elinomfutho ophezulu lemishini yomanyolo"

GB/T5310 “Amashubhu ensimbi angenamthungo ama-boilers anomfutho ophezulu"

GB9948iqukethe amazinga ensimbi e-chromium molybdenum: 12CrMo, 15CrMo, 1Cr2Mo, 1Cr5Mo njalo njalo.

GB6479iqukethe ibanga lensimbi ye-chromium molybdenum: 12CrMo, 15CrMo, 1Cr5Mo njalo njalo.

GB/T5310iqukethe insimbi ye-chromium-molybdenum kanye ne-chromium-molybdenum vanadium steel material grades: 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12Cr1MoVG, njll.

Phakathi kwazo,GB9948isetshenziswa kakhulu.
