I-GB13296-2013 (Amapayipi ensimbi angenamthungo ama-boiler kanye nama-heat exchanger). Isetshenziswa kakhulu kuma-boiler, ama-superheater, ama-heat exchanger, ama-condenser, ama-catalytic tubes, njll. ezinkampani zamakhemikhali. Kusetshenziswe ipayipi lensimbi elinokushisa okuphezulu, elinomfutho ophezulu, elingagqwali. Izinto zalo ezimele yi-0Cr18Ni9, 1Cr18Ni9Ti, 0Cr18Ni12Mo2Ti, njll. GB/T14975-1994 (Ipayipi lensimbi engenamthungo lensimbi engagqwali lesakhiwo). Isetshenziswa kakhulu kwisakhiwo esijwayelekile (ukuhlobisa ihhotela kanye nezindawo zokudlela) kanye nesakhiwo semishini samabhizinisi amakhemikhali, amelana nokugqwala komoya kanye ne-asidi futhi anamapayipi ensimbi aqinile athile. Izinto zalo ezimele yi-0-3Cr13, 0Cr18Ni9, 1Cr18Ni9Ti, 0Cr18Ni12Mo2Ti, njll.

I-GB/T14976-2012 (Ipayipi lensimbi engenasici elingenamthungo lokuthuthwa koketshezi). Isetshenziswa kakhulu kumapayipi athutha izinto ezibolayo. Izinto ezimele yi-0Cr13, 0Cr18Ni9, 1Cr18Ni9Ti, 0Cr17Ni12Mo2, 0Cr18Ni12Mo2Ti, njll.

I-YB/T5035-2010 (Amapayipi ensimbi angenamthungo emikhono ye-axle yemoto). Isetshenziswa kakhulu ukwenza amapayipi ensimbi angenamthungo ekhwalithi ephezulu ensimbi yesakhiwo sekhabhoni kanye nensimbi yesakhiwo ye-alloy egoqeka ngokushisayo emikhono ye-half-axle yemoto kanye namapayipi e-axle ezindlu ze-drive axle. Izinto zayo ezimele ziyi-45, 45Mn2, 40Cr, 20CrNi3A, njll.

I-API SPEC 5L-2018 (incazelo yepayipi yomugqa), ehlanganiswe futhi ekhishwe yi-American Petroleum Institute, ivame ukusetshenziswa emhlabeni wonke.

Ipayipi lomugqa: lifaka amapayipi angenamthungo nahlanganisiwe. Amaphethelo epayipi aneziphetho ezisicaba, iziphetho ezinentambo kanye neziphetho zesokhethi; izindlela zokuxhuma ukushisela kokuphela, ukuxhumana kokuxhuma, ukuxhumana kwezisokhethi, njll. Izinto eziyinhloko yi-GR.B, X42, X52. X56, X65, X70 kanye nezinye izinhlobo zensimbi.

I-API SPEC5CT-2012 (Incazelo Yesitsha kanye Nokucushwa Kwepayipi) ihlanganiswe futhi ikhishwe yi-American Petroleum Institute (i-American Petreleum Instiute, ebizwa ngokuthi “i-API”) futhi isetshenziswa kuzo zonke izingxenye zomhlaba.

Ikheyisi: Ipayipi elisuka ebusweni bomhlaba liye emthonjeni futhi lisebenza njengodonga lomthombo. Amapayipi axhunywe ngama-coupling. Izinto eziyinhloko yizinga lensimbi njenge-J55, N80, ne-P110, kanye nezinga lensimbi njenge-C90 ne-T95 ezimelana nokugqwala kwe-hydrogen sulfide. Izinga layo eliphansi lensimbi (J55, N80) lingashintshwa ngepayipi lensimbi.

Ukuhambisa Amapayipi: Ipayipi elifakwa ekhasejini lisuka ebusweni bomhlaba liye kungqimba kawoyela, futhi amapayipi axhunywe ngama-coupling noma ngokuhlangene. Umsebenzi walo ukuvumela iyunithi yokupompa ukuthi ithuthe uwoyela isuka kungqimba kawoyela iye emhlabathini ngepayipi. Izinto eziyinhloko yizinga lensimbi ezifana ne-J55, N80, P110, kanye ne-C90, T95 ezimelana nokugqwala kwe-hydrogen sulfide. Izinga layo eliphansi lensimbi (J55, N80) lingashintshwa ngepayipi lensimbi.
