Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Eminyakeni yamuva nje, kuye kwaba nomkhuba emhlabeni wokushintsha amapayipi ensimbi angenamthungo abizayo ngamapayipi ashiselwe asezingeni eliphezulu.Lokhu kubangelwa ikakhulukazi ukuphumelela okuqhubekayo kobuchwepheshe bokukhiqiza amapayipi ashiselwe, okubonakala kulezi zici ezilandelayo:
(1) Ukuthuthuka kobuchwepheshe be-desulfurization kuye kwanciphisa okuqukethwe kwesibabule sensimbi futhi kwathuthukisa izinga lokushisela lamapayipi ensimbi.
(2) Ukusetshenziswa kobuchwepheshe be-vacuum degassing kuthuthukisa ukuhlanzeka kwe-tube blank strip, kunciphisa ukufakwa, futhi kuthuthukisa ikhwalithi yokushisela.
(3) Ngenxa yokwengezwa kwezakhi ezikhethekile ezifana ne-V, Ti, ne-Nb, ukulingana kwekhabhoni kuyehliswa, futhi ukuqina namandla epayipi lensimbi kuyathuthukiswa.
(4) Ukuthuthukiswa kobuchwepheshe bokuginqika okushisayo kuye kwathuthukisa ukunemba kwe-dimensional komcu futhi ngaleyo ndlela kwehlise ukuchezuka kobukhulu bepayipi elishiselwe.
(5) Ukuthuthukiswa kwezindlela zokuhlola ikhwalithi, njengokuhlola okungabhubhisi kwe-ultrasonic, imishini yokuhlola i-hydraulic nezinye izinto zokusebenza, ukuze kuqinisekiswe ikhwalithi yomkhiqizo wokugcina.

Amapayipi ensimbi akhethwe amabhizinisi e-petrochemical ngokuvamile asebenzisa amapayipi ensimbi angenamthungo ukuze athuthe uketshezi ngoba kufanele amelane nezingcindezi ezithile.Ngo-1996, ngesikhathi "soHlelo Lukazwelonke Lweminyaka Eyisishagalolunye Lweminyaka Emihlanu" iphrojekthi ebalulekile yokwakha "iphrojekthi ye-Maoming 300,000 t ethylene", "Iphrojekthi Yokuthuthwa Kwepayipi Lomkhiqizo Wase-Mushui" kanye "Nephrojekthi Yesibili Yepayipi Lomkhiqizo Wase-Maoshui" ingxenye yenqubo yokudlulisa amabanga amade iyadingeka. 325mm× 8mm, 168mm × 7mm, 219mm × 7mm ipayipi lensimbi, ikakhulukazi elisetshenziselwa ukuthuthwa kukaphethiloli, udizili, uphalafini, njll.

Imboni yamapayipi ensimbi yaseShayina yaqala ngeminyaka yawo-1950 futhi yaqala sekwephuzile.Inqubo yokukhiqiza kanye nobuchwepheshe kuhluke kakhulu kwamazwe athuthukile.Amabhizinisi amaningi anenqubo nemishini engaphelele, ukuntuleka kwezindlela zokuhlola ezidingekayo, futhi asebenzisa i-short-band ne-band-band materials enekhwalithi ephansi njengezinto zokusetshenziswa, okuholela kububanzi obuncane bemikhiqizo yamapayipi ashiselwe, umthamo ophansi wokuthwala ingcindezi, umkhiqizo ongenangqondo. isakhiwo, kanye nama-80% okukhiqizwa kwamapayipi ashiselwe.Ingasetshenziswa njengoketshezi olunomfutho ophansi ohambisa ipayipi lamanzi, futhi ingxenye yamapayipi akhethekile ahlukahlukene iphansi.Leli zinga eliphansi lempahla yamapayipi ashiselwe kanye nezinga lobuchwepheshe lenza izinga lomkhiqizo lingaqinisekisiwe.Ngakho-ke, ukusetshenziswa kwesikhathi eside kwamapayipi ensimbi angenamthungo abizayo njengamapayipi amapayipi, imigodi kawoyela namapayipi kawoyela kudala imfucuza enkulu.

Okunye ukusebenza kobuchwepheshe kwepayipi lensimbi ye-erw kungcono kunamapayipi ensimbi angenamthungo, kodwa intengo iphansi kakhulu kunaleyo yamapayipi ensimbi angenamthungo, kodwa ayikasetshenziswa kabanzi embonini ye-petrochemical.Izizathu eziyinhloko yilezi:
(1) Umqondo wendabuko owakhiwe isikhathi eside.Lapho ukhetha izinto zokwakha, abaklami babheka ikakhulukazi ukuthi izinto ezibonakalayo zithembekile yini futhi abavamile ukucabangela izindleko zezinto.Ngakho-ke, akunakwenzeka ukusebenzisa ngesibindi amapayipi ensimbi e-erw.
(2) Uhlelo lokutshalwa kwezimali lwamaphrojekthi okwakhiwa kwebhizinisi le-petrochemical lukhawulela isinyathelo sokukhetha amapayipi ensimbi kanye nokunciphisa izindleko.Abatshalizimali ikakhulukazi bacabangela ukusungulwa kwephrojekthi yephrojekthi, imithombo yoxhaso, ukuqhubeka kokwakhiwa nezinye izici, kanye nesidingo esincane sabaklami sokunciphisa izindleko zezinto ezibonakalayo.
(3) Umthungo oqondile waseShayina omelana nogesi oshiselwe ipayipi lensimbi elakhiwe sekwephuzile, futhi akukakakwazi ukukhiqiza ipayipi elikhulu eliwububanzi obuqondile lomthungo elikhudlwana kuno-508mm, ngaleyo ndlela kukhawulelwe ngokufanelekile ukusetshenziswa okubanzi kwepayipi lensimbi ye-erw.
