I-GB13296-2013 (Iipayipi zensimbi ezingenamthungo kwiibhoyili kunye nabatshintshisi bokushisa). Isetyenziswa kakhulu kwiibhoyila, ii-superheaters, i-heat exchangers, i-condensers, i-catalytic tubes, njl. Isetyenziselwe ubushushu obuphezulu, uxinzelelo oluphezulu, umbhobho wentsimbi onganyangekiyo kwi-corrosion. Izinto ezimele ummeli zi-0Cr18Ni9, 1Cr18Ni9Ti, 0Cr18Ni12Mo2Ti, njl. I-GB / T14975-1994 (i-stainless steel seamless pipe for structure). Isetyenziselwa ikakhulu kwisakhiwo esiqhelekileyo (ihotele kunye nomhombiso wokutyela) kunye nesakhiwo somatshini samashishini ekhemikhali, axhathisayo kwi-atmospheric and acid corrosion kwaye anamandla athile emibhobho yentsimbi. Izixhobo zayo ezimele ziyi-0-3Cr13, 0Cr18Ni9, 1Cr18Ni9Ti, 0Cr18Ni12Mo2Ti, njl.

I-GB/T14976-2012 (Insimbi engenamthungo umbhobho wentsimbi yokuthuthwa kwamanzi). Isetyenziswa kakhulu kwimibhobho ethutha imidiya eyonakalisayo. Izinto ezimeleyo zi-0Cr13, 0Cr18Ni9, 1Cr18Ni9Ti, 0Cr17Ni12Mo2, 0Cr18Ni12Mo2Ti, njl.

YB/T5035-2010 (Imibhobho yentsimbi engenamthungo kwimikhono ye-axle yemoto). Ikakhulu isetyenziselwa ukwenza umgangatho ophezulu wekhabhoni yentsimbi kunye nentsimbi yolwakhiwo lwentsimbi eshushu-eqengqelekisiweyo enomthungo wemibhobho yemoto yemoto enemikhono enesiqingatha se-asi kunye neetyhubhu ze-asi ze-axle housings. Izinto zayo ezimele ziyi-45, 45Mn2, 40Cr, 20CrNi3A, njl.

I-API SPEC 5L-2018 (inkcazo yombhobho womgca), ehlanganiswe kwaye ikhutshwe yi-American Petroleum Institute, isetyenziswa ngokuqhelekileyo kuwo wonke umhlaba.

Umbhobho womgca: ubandakanya imibhobho engenamthungo kunye ne-welded. Iziphelo zombhobho zineziphelo ezisicaba, iziphelo ezinemisonto kunye neziphelo zesokethi; iindlela zokudibanisa ziphela i-welding, ukudibanisa ukudibanisa, ukudibanisa i-socket, njl. Izinto eziphambili ziyi-GR.B, X42, X52. X56, X65, X70 kunye namanye amabakala entsimbi.

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

kwi:

Casing: Umbhobho osuka kumphezulu womhlaba uye equleni kwaye usebenza njengodonga lwequla. Imibhobho idityaniswe ngokudibanisa. Izinto eziphambili ziyimigangatho yensimbi efana ne-J55, i-N80, kunye ne-P110, kunye namabakala ensimbi afana ne-C90 kunye ne-T95 echasene ne-hydrogen sulfide corrosion. Ibakala layo eliphantsi lentsimbi (J55, N80) linokudityaniswa nombhobho wentsimbi.

I-Tubing: Umbhobho ofakwe kwi-casing ukusuka kumhlaba womhlaba ukuya kwinqanaba le-oyile, kwaye imibhobho ixhunywe ngokudibanisa okanye ngokudibeneyo. Umsebenzi wayo kukuvumela iyunithi yokupompa ukuba ihambise ioli ukusuka kwinqanaba leoli ukuya emhlabeni ngokusebenzisa i-tubing. Izinto eziphambili ziyimigangatho yensimbi efana ne-J55, i-N80, i-P110, kunye ne-C90, i-T95 echasene ne-hydrogen sulfide corrosion. Ibakala layo eliphantsi lentsimbi (J55, N80) linokudityaniswa nombhobho wentsimbi.
