I-GB13296-2013 (Amapayipi ensimbi angenamthungo ama-boilers kanye nabashintshi bokushisa). Isetshenziswa kakhulu kuma-boilers, ama-superheaters, ama-heaters, ama-condensers, amashubhu e-catalytic, njll. yamabhizinisi amakhemikhali. Kusetshenziswe izinga lokushisa eliphezulu, umfutho ophezulu, ipayipi lensimbi elingagqwali. Izinto zayo ezimele ziyi-0Cr18Ni9, 1Cr18Ni9Ti, 0Cr18Ni12Mo2Ti, njll. I-GB/T14975-1994 (ipayipi lensimbi engenamthungo yesakhiwo). Isetshenziselwa ikakhulukazi isakhiwo esijwayelekile (umhlobiso wehhotela nezindawo zokudlela) kanye nesakhiwo semishini samabhizinisi amakhemikhali, amelana nokugqwala komkhathi kanye ne-asidi futhi abe namapayipi athile ensimbi anamandla. Izinto zayo ezimele ziyi-0-3Cr13, 0Cr18Ni9, 1Cr18Ni9Ti, 0Cr18Ni12Mo2Ti, njll.

I-GB/T14976-2012 (Ipayipi lensimbi engenamthungo yokuthutha uketshezi). Ikakhulukazi isetshenziselwa amapayipi athutha imidiya ebolayo. Izinto ezimele i-0Cr13, 0Cr18Ni9, 1Cr18Ni9Ti, 0Cr17Ni12Mo2, 0Cr18Ni12Mo2Ti, njll.

I-YB/T5035-2010 (Amapayipi ensimbi angenamthungo emikhono ye-asi yemoto). Isetshenziswa kakhulu ukwenza insimbi yesakhiwo sekhabhoni ephezulu yekhwalithi ephezulu kanye nensimbi yesakhiwo esinamapayipi ensimbi engenamthungo agingqike agingqike emoto emikhono ye-axle yemoto kanye namashubhu e-asi e-axle yezindlu. Izinto zayo ezimele ziyi-45, 45Mn2, 40Cr, 20CrNi3A, njll.

I-API SPEC 5L-2018 (incazelo yepayipi lomugqa), ehlanganiswe futhi yakhishwa yi-American Petroleum Institute, isetshenziswa kakhulu emhlabeni jikelele.

Ipayipi lomugqa: lihlanganisa amapayipi angenamthungo futhi ashiselwe. Iziphetho zamapayipi zineziphetho eziyisicaba, iziphetho ezinezintambo kanye neziphetho zesokhethi; izindlela zokuxhuma i-welding yokuphela, uxhumano lokuhlanganisa, uxhumano lwesokhethi, njll. Izinto eziyinhloko ziyi-GR.B, X42, X52. X56, X65, X70 namanye amabanga ensimbi.

I-API SPEC5CT-2012 (Casing and Tubing Specification) ihlanganiswe futhi ikhishwe yi-American Petroleum Institute (American Petreleum Instiute, ebizwa ngokuthi “API”) futhi isetshenziswa kuzo zonke izingxenye zomhlaba.

ku:

I-Casing: Ipayipi elisuka endaweni ephansi liye emthonjeni futhi lisebenza njengodonga lomthombo. Amapayipi axhunywe ngama-couplings. Izinto eziyinhloko amamaki ensimbi afana ne-J55, N80, ne-P110, kanye namabanga ensimbi afana ne-C90 ne-T95 amelana nokugqwala kwe-hydrogen sulfide. Izinga layo lensimbi eliphansi (J55, N80) lingafakwa ipayipi lensimbi elishiselwe.

I-Tubing: Ipayipi elifakwe ku-casing ukusuka endaweni engaphansi kuya ku-oyela ungqimba, futhi amapayipi axhunywe ngokuhlanganisa noma ngokuhlangene. Umsebenzi wayo ukuvumela iyunithi yokupompa ukuthi ithuthe uwoyela ukusuka kungqimba lwamafutha ukuya emhlabathini ngokusebenzisa ishubhu. Izinto eziyinhloko amamaki ensimbi afana ne-J55, N80, P110, ne-C90, T95 amelana nokugqwala kwe-hydrogen sulfide. Izinga layo lensimbi eliphansi (J55, N80) lingafakwa ipayipi lensimbi elishiselwe.
