Ishubhu eliyisikweleuhlobo lweshubhu yensimbi eyisikwele engenalutho, eyaziwa nangokuthi ishubhu yesikwele,ipayipi elingunxande. Imininingwane yayo ivezwa ngobubanzi bangaphandle * ubukhulu bodonga ngamamilimitha. Yenziwe ngomucu wensimbi ogoqwe ngokushisa ngokugoqa okubandayo noma ngokudweba okubandayo.
Ukusetshenziswa kwepayipi lesikwele elingenamthungo:
Isikwele esingenamthungo kanyeyuantai tube elingunxandezisetshenziswa kabanzi. Ngokuvamile isetshenziselwa ukukhiqiza izingxenye zesakhiwo kanye nezingxenye zemishini, njengepayipi lokubhoboza uwoyela, umgodi wokudlulisa izimoto, uhlaka lwebhayisikili kanye ne-scaffolding yensimbi esetshenziswa ekwakheni, ezenziwe ngensimbi yesakhiwo yekhabhoni esezingeni eliphezulu ngokugoqa okushisayo noma ukudweba okubandayo, futhi ikakhulukazi zisetshenziswa njengamapayipi noma izingxenye zesakhiwo ukuthutha uketshezi.
Uhlobo lwepayipi elingunxande elingenamthungo:
1. Ngokusho kwezinto ezibonakalayo, ingahlukaniswa ibe yinsimbi yesakhiwo sekhabhoni evamile kanye nensimbi yesakhiwo enamandla aphezulu e-alloy. Okuqukethwe kwekhabhoni kweyokuqala akumele kudlule u-4.5%; i-sulfur ≤ 0.035; i-phosphorus ≤ 0.005; i-chromium ≤ 0.15; okuqukethwe yi-nickel <0.25; ithusi ≤ 0.30; Okugcina kuqukethe inani elincane le-silicon, i-manganese ne-vanadium ngaphezu kwe-carbon, i-sulfur, i-phosphorus kanye ne-chromium.
2. Ngokusho kwekhwalithi yobuso:
(1) Ukuqeda:
1 Izindawo zangaphakathi nezangaphandle zepayipi lesikwele elingenamthungo kufanele zibe bushelelezi futhi zibe yisicaba ngaphandle kwamabhamuza nemibimbi.
2 Uma indawo yangaphakathi ingaphansi kuka-100 mm2, ukubekezelela okuvumelekile kwendawo yangaphakathi kungu-± 0.2 mm.
3 Uma indawo yangaphakathi ingaphezu kuka-100 mm2, ukubekezelela okuvumelekile kwendawo yangaphakathi kungu-± 0.5 mm.
4 Akukho mifantu noma imigoqo evunyelwe ebusweni obungaphakathi; 5 Akumelwe kube khona isilonda 6 Akukho mikrwelo esobala kanye namabala okuphuka.
(2) Ukuthamba:
1 Izindawo zangaphakathi nezangaphandle zamapayipi ayisikwele angenamthungo kufanele zibe ziyisicaba futhi zibushelelezi.
2 Akufanele kube nokungalingani okusobala uma kubhekwa ngengilazi yokukhulisa engu-10X.
3 Ubuso bokugcina be-nozzle buqondile emgqeni ophakathi wepayipi.
4 Uhlangothi olungemuva lwepayipi kufanele lungabi nama-burrs.
5 Akumelwe kube khona ukushwabana ekugobeni kombhobho.
6 Zombili iziphetho zepayipi kufanele zilingane.
7 Akukho ukuvuvuka okusobala okuvunyelwe ekushiseni ngemva kokususwa kokugqwala.
8 Akufanele kube khona imigodi esobala.
9 Azikho iziphambeko ezithinta ukusetshenziswa ezivunyelwe.
10 Uma umshini wokugoqa ipuleti usetshenziselwa ukushisela, irediyasi yefillet ekushiseleni akumele ibe ngaphansi kobukhulu bensimbi eyisisekelo.
(3) Ukunemba kobukhulu:
1 Iphutha lokuzungeza akumele lidlule ukuphambuka okuphezulu okuchazwe kuzinga elifanele ngaphezu kuka-2 mm/m2.
2 Ukuphambuka kokuqondisa kanye ne-engeli akumele kudlule i-1/20 yokuphambuka okuphezulu okuchazwe kuzinga elihambisanayo.
3 Ukuphambuka komkhawulo wobude akufanele kube ngaphezu kwezikhathi eziyi-1.5 zenani elichaziwe elihambisanayo.
Ukulawulwa kwekhwalithiipayipi lensimbi le-yuantaikuqinile kakhulu, ngakho amakhasimende angakhetha ngokuzethemba.Inkampani ye-YuantaiNgithole amalungelo obunikazi angu-77,Insimbi ye-Yuantaiuwine iqhawe elilodwa embonini yamapayipi angunxande iminyaka eyi-10 ilandelana,
Uma udinga ukutholaintengo yepayipi yensimbi ye-yuantai，Sicela usithinte.
Isikhathi sokuthunyelwe: Disemba-09-2022
