Kusarudza mapaipi esimbi asina musono kwakanyatsojeka!

Ndezvipi zvinodiwa pakusarudza mapaipi esimbi asina musono ekufambisa mvura anowanzo shandiswa muindasitiri yedu yekushanda? Tarisa muchidimbu vashandi vedu vemapaipi epressure:

Mapaipi esimbi asina musono mapaipi esimbi asina welds anogadzirwa nenzira dzinopisa dzakadai sekuboora nekukanda zvinopisa.

Kana zvichidikanwa, pombi yekuchenesa inopisa inogona kudhonzwa zvakanyanya nechando zvichienderana nechimiro, saizi uye mashandiro anodiwa. Parizvino, mapaipi esimbi asina musono (DN15-600) ndiwo mapaipi anoshandiswa zvakanyanya mumichina yekugadzira petrochemical.

Kuongororwa: Kazhinji mapaipi esimbi ekutakura mvura anofanirwa kuongororwa nekuumbwa kwemakemikari, kuyedzwa kwekumanikidzwa, kuyedzwa kwekutsatirira uye kuyedzwa kwe hydraulic. Mapaipi esimbi akajairwa eGB5310, GB6479, uye GB9948, pamusoro pekuyedzwa kunofanirwa kuitwa pamapaipi esimbi ekutakura mvura, kuyedzwa kwekupenya uye kuyedzwa kwekukanganisa kunodiwawo; zvinodiwa zvekuongorora kugadzirwa kwemapaipi matatu aya esimbi zvakaomesesa. Standard yeGB6479 inoitawo zvinodiwa zvakakosha zvekusimba kwekupisa kwechinhu ichi. Pamusoro pezvinodiwa zvekuyedzwa kwemapaipi esimbi ekutakura mvura, mapaipi esimbi eGB3087 standard anodawo kuyedzwa kwekukombama kunotonhora. Mapaipi esimbi akajairwa eGB/T8163, pamusoro pezvinodiwa zvekuyedzwa kwemapaipi esimbi ekutakura mvura, zvichienderana nechibvumirano zvinoda kuyedzwa kwekuwedzerwa uye kuyedzwa kwekukombama kunotonhora. Zvinodiwa zvekugadzira zvemhando mbiri idzi dzemachubhu hazvisi zvakaoma semhando nhatu dzekutanga.

Kugadzira: Mapaipi esimbi eGB/T8163 neGB3087 anowanzo nyungudutswa muchoto chakavhurika kana muchina wekushandura, uye tsvina dzawo nezvikanganiso zvemukati zvakakura. GB9948 inonyanya kushandisa kunyungudutswa kwechoto chemagetsi. Mazhinji acho akabatana nemaitiro ekuchenesa kunze kwechoto, uye zvikanganiso zvemukati nezvikanganiso zvemukati zvidiki. Mitemo yeGB6479 neGB5310 pachayo inotaura zvinodiwa pakunatsa kunze kwechoto, nekushomeka kushoma kwechinhu uye zvikanganiso zvemukati, uye mhando yepamusoro yezvinhu.

Sarudzo: Kazhinji, pombi yesimbi yakajairika yeGB/T8163 yakakodzera mafuta, mafuta negesi uye midziyo yeruzhinji ine tembiricha yekugadzira iri pasi pe350°C uye kumanikidzwa kuri pasi pe10.0MPa; yemafuta, mafuta nemidziyo yegesi, kana tembiricha yekugadzira inopfuura 350°C Kana kana kumanikidzwa kuri kupfuura 10.0MPa, pombi dzesimbi dzakajairika dzeGB9948 kana GB6479 dzinofanira kushandiswa; yemapaipi anoshandiswa muhydrogen, kana mapaipi anoshanda munzvimbo dzinokurumidza ngura, GB9948 kana GB6479 dzinofanirawo kushandiswa. Mapaipi ese esimbi yekabhoni anoshandiswa patembiricha yakaderera (pasi pe -20°C) anofanira kushandisa mwero weGB6479, uye ndiwo chete unotsanangura zvinodiwa zvekusimba kwechinhu chacho patembiricha yakaderera. Mwero weGB3087 neGB5310 ndiwo mwero wakagadzirirwa mapaipi esimbi yeboiler. "Mitemo yeKutarisira Kuchengetedzwa kweBoiler" inosimbisa kuti mapaipi ese akabatana nebhoiler ndeekutarisira, uye kushandiswa kwezvinhu nemazinga kunofanirwa kutevedzera zvinodiwa ne "Mitemo yeKutarisira Kuchengetedzwa kweBoiler". Saka, anoshandiswa mumabhoiler, magwenya emagetsi, nzvimbo dzekugadzira dzinodziya uye petrochemical. Mapaipi ese ehutsi hweveruzhinji (anopihwa nesystem) anofanira kushandisa mitemo yeGB3087 kana GB5310. Zvakakosha kuziva kuti mutengo wemapaipi esimbi ane mitemo yemapaipi esimbi emhando yepamusoro wakakwira. Semuenzaniso, mutengo weGB9948 wakakwira nehafu yemutengo wezvinhu zveGB8163. Saka, pakusarudza mitemo yezvinhu zvepombi yesimbi, kufungwa kwakazara kunofanirwa kupihwa kune mamiriro ekushandiswa, ayo anofanira kuva akavimbika uye asingadhuri. Zvinofanirawo kucherechedzwa kuti mapaipi esimbi anoenderana nezvinodiwa zveGB/T20801 uye TSGD0001, GB3087 uye GB8163 haafanirwe kushandiswa pamapaipi eGC1 (kunze kwekunge rimwe nerimwe riri re ultrasonic, hunhu hwaro hahusi hwakaderera pane L2.5, uye hunogona kushandiswa kuGC1 ine dhizaini yekumanikidza isingapfuure mapaipi e4.0Mpa).

(二)Pombi yesimbi isina musono

Mumichina yekugadzira petrochemical, zviyero zvemapaipi esimbi asina musono anoshandiswa zvakanyanya e chromium-molybdenum steel uye chromium-molybdenum-vanadium steel zvisina musono ndeizvi GB9948 “Mapaipi esimbi asina musono ekupwanya petroleum” GB6479 “Mapaipi esimbi asina musono emidziyo yefetereza ane simba guru” GB/T5310 “Mapaipi esimbi asina musono epabhoyara rine simba guru》GB9948 ine chromium-molybdenum steel material grades: 12CrMo, 15CrMo, 1Cr2Mo, 1Cr5Mo, nezvimwewo. Magiredhi esimbi echromium-molybdenum anowanikwa muGB6479: 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 padzo, inonyanya kushandiswa iGB9948, ona pamusoro apa kuti uwane mamiriro ekusarudza.

(三) Pipe yesimbi isina musono

Zviyero zvepombi yesimbi isina musono yesimbi isingasvibiswi zvinoshandiswa zvakanyanya ndeizvi:

Kune zviyero zvishanu: GB/T14976, GB13296, GB9948, GB6479, uye GB5310. Pakati pazvo, mamakisi maviri kana matatu chete esimbi isina ngura akanyorwa muzvikamu zvitatu zvekupedzisira, uye haasi mamakisi ezvinhu anowanzo shandiswa.

Saka, kana zviyero zvemapaipi esimbi isina ngura zvakapfava zvichishandiswa muinjiniya, zviyero zveGB/T14976 neGB13296 ndizvo zvinonyanya kushandiswa.

GB/T14976 “Pombi yesimbi isina musono yesimbi yekufambisa mvura”:

Magiredhi ezvinhu: 304, 304L nedzimwe mhando gumi nepfumbamwe dzakakodzera kutakurwa kwemvura.

GB13296 “Machubhu esimbi isina musono esimbi isina ngura emabhaira uye ekuchinjana kupisa”:

Magiredhi ezvinhu: 304, 304L nedzimwe mhando makumi maviri neshanu.

Pakati padzo, simbi isina ngura ine kabhoni shoma (304L, 316L) ine kabhoni yakanaka kwazvo. Mune mamwe mamiriro ezvinhu, inogona kutsiva simbi isina ngura yakasimba (321, 347) kuti irambe ngura; simbi isina ngura ine kabhoni shoma ine kabhoni shoma ine kabhoni yepamusoro, kazhinji inoshandiswa chete patembiricha iri pasi pe525℃; simbi isina ngura yakasimba ine kabhoni yakanaka uye kabhoni yepamusoro, asi Ti mu321 inonyungudika nyore nyore uye inorasika panguva yekusveta, nokudaro ichideredza kabhoni, mutengo wayo wakakwira, rudzi urwu rwezvinhu runowanzo shandiswa mune zviitiko zvakakosha, 304, 316 ine kabhoni yakawanda, mutengo wakachipa, saka inoshandiswa zvakanyanya.
