GB13296-2013 (Iipayipi zentsimbi ezingenamthungo zeebhoyila kunye nezitshintshi zobushushu). Isetyenziswa kakhulu kwiibhoyila, ii-superheater, ii-heat exchangers, ii-condenser, ii-catalytic tubes, njl.njl. zeenkampani zeekhemikhali. Isetyenziswa kwipayipi yentsimbi enobushushu obuphezulu, uxinzelelo oluphezulu, engamelani nokugqwala. Izixhobo zayo ezimeleyo yi-0Cr18Ni9, 1Cr18Ni9Ti, 0Cr18Ni12Mo2Ti, njl.njl. GB/T14975-1994 (Ipayipi yentsimbi engenamthungo yentsimbi engenamthungo yesakhiwo). Isetyenziswa kakhulu kwisakhiwo ngokubanzi (ukuhombisa ihotele kunye nerestaurant) kunye nesakhiwo soomatshini seenkampani zeekhemikhali, ezimelana nokugqwala komoya kunye ne-asidi kwaye zinemibhobho yentsimbi enamandla athile. Izixhobo zayo ezimeleyo yi-0-3Cr13, 0Cr18Ni9, 1Cr18Ni9Ti, 0Cr18Ni12Mo2Ti, njl.njl.

GB/T14976-2012 (Ipayipi yentsimbi engenasici engenamthungo yokuthutha ulwelo). Isetyenziswa kakhulu kwiipayipi ezithutha izinto ezibolayo. Izinto ezimeleyo zezi: 0Cr13, 0Cr18Ni9, 1Cr18Ni9Ti, 0Cr17Ni12Mo2, 0Cr18Ni12Mo2Ti, njl.njl.

I-YB/T5035-2010 (Iipayipi zentsimbi ezingenamthungo zeemikhono zee-axle zeemoto). Isetyenziswa kakhulu ekwenzeni isinyithi sekhabhoni esisemgangathweni ophezulu kunye nesinyithi se-alloy esingenamthungo iipayipi zentsimbi engenamthungo ezihot-rolled zeemikhono zee-axle zeemoto kunye neetyhubhu zee-axle zezindlu zee-axle zokuqhuba. Izixhobo zayo ezimeleyo yi-45, 45Mn2, 40Cr, 20CrNi3A, njl.

I-API SPEC 5L-2018 (inkcazo yombhobho womgca), equlunqwe kwaye ikhutshwe yi-American Petroleum Institute, isetyenziswa kakhulu kwihlabathi liphela.

Umbhobho womgca: uquka imibhobho engenamthungo nedibeneyo. Iziphelo zemibhobho zineziphelo ezithe tyaba, iziphelo ezinemisonto kunye neziphelo zesokhethi; iindlela zokudibanisa kukuwelda kokuphela, uqhagamshelo lokudibanisa, uqhagamshelo lwesokhethi, njl. Izixhobo eziphambili yi-GR.B, X42, X52. X56, X65, X70 kunye nezinye iintlobo zentsimbi.

I-API SPEC5CT-2012 (Inkcazo yeCasing and Tubing) iqulunqwe kwaye ikhutshwe yi-American Petroleum Institute (i-American Petreleum Instiute, ebizwa ngokuba yi-"API") kwaye isetyenziswa kuzo zonke iindawo zehlabathi.

Ikheyiji: Umbhobho osuka kumphezulu womhlaba uye emthonjeni kwaye usebenza njengodonga lwequla. Imibhobho iqhagamshelwe ngamakhonkco. Izinto eziphambili ziiklasi zentsimbi ezifana ne-J55, i-N80, kunye ne-P110, kunye neeklasi zentsimbi ezifana ne-C90 kunye ne-T95 ezimelana nokugqwala kwe-hydrogen sulfide. Umgangatho wayo wentsimbi ephantsi (J55, N80) unokudityaniswa nombhobho wentsimbi.

Ukuxubha: Umbhobho ofakwe kwi-casing ukusuka kumphezulu womhlaba ukuya kumaleko weoyile, kwaye imibhobho iqhagamshelwe ngamakhonkco okanye ngokudibeneyo. Umsebenzi wayo kukuvumela iyunithi yokumpompa ukuba ithuthe ioyile ukusuka kumaleko weoyile ukuya emhlabeni ngetyhubhu. Izixhobo eziphambili ziiklasi zentsimbi ezifana ne-J55, N80, P110, kunye ne-C90, T95 ezimelana nokugqwala kwe-hydrogen sulfide. Umgangatho wayo wentsimbi ephantsi (J55, N80) unokufakelwa umbhobho wentsimbi.
