Isicelo, Imininingwane kanye Nezakhiwo Zepayipi Lensimbi Yekhabhoni Elikhulu Elinobubanzi

Amapayipi ensimbi yekhabhoni amakhulu ububanzingokuvamile kubhekisela kumapayipi ensimbi yekhabhoni anobubanzi bangaphandle obungaphansi kuka-200mm. Enziwe ngensimbi yekhabhoni, ayizinto ezibalulekile emikhakheni yezimboni kanye nengqalasizinda ngenxa yamandla awo aphezulu, ukuqina okuhle, kanye nezakhiwo ezinhle kakhulu zokushisela. Ukushisela okushisayo kanye nokujikijela okujikelezayo kuvame ukusetshenziswa ekukhiqizweni kwawo.Amapayipi ensimbi ashisiwe ashisayozisetshenziswa kabanzi ekusetshenzisweni komfutho ophezulu ngenxa yobukhulu bazo bodonga obufanayo kanye nesakhiwo esiminyene.

Imininingwane Eyenziwe Ngokwezifiso: Ukuhlangabezana Nezidingo Zephrojekthi Ezihlukahlukene

Izimpawu zepayipi lensimbi yekhabhoni elinobubanzi obukhulu zichazwa ububanzi bangaphandle, ukujiya kodonga, ubude, kanye nezinga lezinto ezibonakalayo. Ububanzi bangaphandle buvame ukuba phakathi kuka-200 mm no-3000 mm. Ubukhulu obukhulu obunjalo bubenza bakwazi ukuthutha ukugeleza koketshezi okukhulu futhi banikeze ukwesekwa kwesakhiwo, okubalulekile kumaphrojekthi amakhulu.

Ipayipi lensimbi eligoqekile elishisayo livelele ngezinzuzo zalo zenqubo yokukhiqiza: ukugoqeka okushisa okuphezulu kuguqula ama-billet ensimbi abe amapayipi anobukhulu obufanayo bodonga kanye nesakhiwo sangaphakathi esiqinile. Ukubekezelela kwayo ububanzi bangaphandle kungalawulwa ngaphakathi kuka-±0.5%, okwenza ifaneleke kumaphrojekthi anezidingo eziqinile zobukhulu, njengamapayipi omusi ezitshalweni ezinkulu zamandla okushisa kanye namanethiwekhi okushisa asemadolobheni.

Ipayipi lensimbi yekhabhoni le-Q235futhiIpayipi lensimbi yekhabhoni le-A36banemingcele ecacile yemininingwane yamabanga ahlukene ezinto zokwakha.

1.Ipayipi lensimbi le-Q235: Ipayipi lensimbi le-Q235 liyipayipi lensimbi elivamile lesakhiwo sekhabhoni eShayina. Njengoba linamandla okukhiqiza angu-235 MPa, livame ukukhiqizwa ngobukhulu bodonga obungu-8-20 mm futhi lisetshenziswa kakhulu ekuthuthweni koketshezi olunomfutho ophansi, njengokuhlinzekwa kwamanzi kamasipala kanye nokugeleza kwamanzi, kanye namapayipi egesi ezimboni ajwayelekile.

2.Ipayipi lensimbi yekhabhoni le-A36: Ipayipi lensimbi yekhabhoni i-A36 liyizinga lensimbi eliyinhloko emakethe yamazwe ngamazwe. Linamandla okukhiqiza aphezulu kancane (250MPa) kanye nokuguquguquka okungcono. Inguqulo yalo enobubanzi obukhulu (ngokuvamile enobubanzi bangaphandle obungu-500mm noma ngaphezulu) isetshenziswa kabanzi emipayipini yokuqoqa uwoyela negesi, edinga ukumelana nokushintshashintsha kwengcindezi ethile kanye nokushisa.

Ukusetshenziswa kwepayipi lensimbi ye-carbon diameter enkulu

Ipayipi lensimbi yekhabhoni elikhulu, elinezinzuzo zalo zokuqina okuphezulu, ukumelana nokucindezela okuphezulu, ukushisela okulula, kanye nokusebenza kahle kwezindleko, linezinhlelo zokusebenza ezingenakuguqulwa emikhakheni eminingi ebalulekile. Lezi zinhlelo zokusebenza zingahlukaniswa ngezigaba ezintathu eziyinhloko: ukudluliselwa kwamandla, ubunjiniyela bengqalasizinda, kanye nokukhiqizwa kwezimboni.

Ukudluliswa kwamandla: Isebenza njenge-"aorta" yokudlulisa uwoyela, igesi, kanye namandla. Amapayipi kawoyela negesi anqamula izifunda (njenge-Central Asia Natural Gas Pipeline kanye ne-West-East Gas Pipeline yasekhaya) asebenzisa ipayipi lensimbi yekhabhoni elikhulu (ikakhulukazi elinobubanzi obungaphandle obungu-800-1400mm).

Ingqalasizinda kanye nobunjiniyela bomasipala: Isekela ukusebenza kwamadolobha kanye namanethiwekhi ezokuthutha. Ekuhlinzekweni kwamanzi kanye nokuthuthwa kwamanzi kamasipala, ipayipi lensimbi yekhabhoni elinobubanzi obukhulu (ububanzi bangaphandle obungu-600-2000mm) liyindlela ekhethwayo yamapayipi okuphakelwa kwamanzi amakhulu asemadolobheni kanye namapayipi okuthuthwa kwamanzi emvula ngenxa yokumelana nokugqwala (okuphila isikhathi esingaphezu kweminyaka engama-30 ngemuva kokwelashwa kokumbozwa kokugqwala) kanye nesivinini sokugeleza okuphezulu.

Ukukhiqizwa kwezimboni: Isebenza njengomgogodla wokukhiqiza okunzima kanye nokukhiqizwa kwamakhemikhali. Izitshalo zemishini esindayo zivame ukusebenzisa amapayipi ensimbi yekhabhoni amakhulu (ubukhulu bodonga obungu-15-30mm) ukuze kusekelwe izisekelo zesitimela se-crane kanye nohlaka olukhulu lwemishini. Umthamo wazo ophezulu wokuthwala umthwalo (ipayipi elilodwa lingamelana nemithwalo eqondile engaphezu kwama-50kN) kusiza ekuqiniseni ukusebenza kwemishini.

amapayipi ensimbi yekhabhoni anobubanzi obukhulu

Izitayela Zemakethe kanye Nombono Wemboni: Isidingo Esikhulayo Samapayipi Asezingeni Eliphezulu

Isidingo semakethe samapayipi ensimbi yekhabhoni anobubanzi obukhulu sikhula kancane kancane kanye nengqalasizinda yomhlaba wonke, amandla, kanye nentuthuko yezimboni. Imikhakha yendabuko efana namakhemikhali kaphethiloli, ukudluliselwa kwamandla, kanye nokuhlinzekwa kwamanzi asemadolobheni kanye nokuthuthwa kwamanzi kusalokhu kuyizinto eziyinhloko ezibangela isidingo. Isidingo samapayipi ensimbi yekhabhoni anobubanzi obukhulu siyaqhubeka nokukhula embonini yamakhemikhali kaphethiloli, kanti isidingo saminyaka yonke kulindeleke ukuthi sifinyelele cishe amathani ayizigidi ezingu-3.2 ngo-2030. Le mboni ithembele kumapayipi ensimbi yekhabhoni anobubanzi obukhulu ukuthutha uwoyela ongahluziwe, imikhiqizo ecolisisiwe, kanye nezinto zokusetshenziswa zamakhemikhali.
