| GB/T9711 | Mamiriro ehunyanzvi ekutumira mapaipi esimbi eindasitiri yemafuta negesi |
Kuongororwa: Kazhinji, mapaipi esimbi ekutakura mvura anofanirwa kuongororwa nekuumbwa kwemakemikari, kuyedzwa kwekumanikidzwa, kuyedzwa kwekutsatirira uye kuyedzwa kwekumanikidzwa kwemvura. Pamusoro pekuyedzwa kunofanirwa kuitwa pamapaipi esimbi ekutakura mvura, mapaipi esimbi eGB5310, GB6479 uye GB9948 anofanirwawo kuitwa kuyedzwa kwekuwedzera uye kuyedzwa kwekukanganisa; zvinodiwa zvekuongorora kugadzirwa kwemapaipi matatu aya esimbi zvakaoma. GB6479 standard inoitawo zvinodiwa zvakakosha zvekusimba kwekupisa kwezvinhu. Pamusoro pezvinodiwa zvekuyedzwa kwemapaipi esimbi ekutakura mvura, mapaipi esimbi eGB3087 standard anofanirwawo kuitwa kuyedzwa kwekukotama kunotonhora. Pamusoro pezvinodiwa zvekuyedzwa kwemapaipi esimbi ekutakura mvura, mapaipi esimbi eGB/T8163 standard anofanirwa kuitwa kuyedzwa kwekukotama uye kuyedzwa kwekukotama kunotonhora zvichienderana nechibvumirano. Zvinodiwa zvekugadzira mapaipi maviri aya hazvina kuoma sematatu ekutanga. Kugadzira: Mapaipi esimbi eGB/T/8163 uye GB3087 standard anonyanya kunyungudutswa nechoto kana converter yakavhurika, uye zvikamu zvavo zvekusachena uye zvikanganiso zvemukati zvakanyanya. GB9948 inonyanya kunyungudutswa nechoto chemagetsi. Vazhinji vavo vakawedzera nzira yekunatsa kunze kwechoto, uye maumbirwo acho nezvikanganiso zvemukati zvishoma. GB6479 neGB5310 zviyero pachazvo zvinotsanangura zvinodiwa pakunatsa kunze kwechoto, nezvikamu zvisina kuchena zvakanyanya uye zvikanganiso zvemukati, uye mhando yepamusoro yezvinhu. Hunhu hwekugadzira hwematanho emapaipi esimbi ari pamusoro apa ari muhurongwa kubva pakaderera kusvika pakakwirira: GB/T8163
(II) Mapaipi esimbi isina musono ine alloy shoma Mumichina yekugadzira petrochemical, zviyero zvemapaipi esimbi isina musono anoshandiswa zvakanyanya chromium-molybdenum steel uye chromium-molybdenum-vanadium steel zvisina musono ndeizvi GB9948 "Mapaipi esimbi asina musono ekupwanya petroleum" GB6479 "Mapaipi esimbi asina musono ane high-pressure yemidziyo yefetereza" GB/T5310 "Mapaipi esimbi asina musono emabhaira ane high-pressure" GB9948 ine chromium-molybdenum steel material grades: 12CrMo, 15CrMo, 1Cr2Mo, 1Cr5Mo, nezvimwewo. GB6479 ine chromium-molybdenum steel material grades: 12CrMo, 15CrMo, 1Cr5Mo, nezvimwewo. GB/T5310 ine chromium-molybdenum steel uye chromium-molybdenum-vanadium steel material grades: 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12Cr1MoVG, nezvimwewo. Pakati pazvo, GB9948 ndiyo inonyanya kushandiswa, uye mamiriro ekusarudza akafanana neari pamusoro apa.
