Ishubhu yesikweleluhlobo lwe-square ingxenye yesikwele shape tube tube, eyaziwa nangokuthi tube square,ithubhu elingunxande. Ukucaciswa kwayo kuvezwe ngamamilimitha obubanzi obungaphandle * ukujiya kodonga. Yenziwe ngomugqa wensimbi ogoqiwe oshisayo ngokugoqa okubandayo noma umdwebo obandayo.
Ukusetshenziswa kwepayipi eliyisikwele elingenamthungo:
Isikwele esingenamthungo futhiyuantai tube elingunxandezisetshenziswa kabanzi. Ivamise ukusetshenziselwa ukwakha izingxenye zesakhiwo kanye nezingxenye eziwumshini, njengepayipi lokubhola uwoyela, umshini wokuhambisa imoto, uhlaka lwebhayisikili kanye nezikafula zensimbi ezisetshenziswa ekwakheni, ezenziwe ngensimbi yekhwalithi ephezulu ye-carbon structural steel ngokugingqika okushisayo noma ngomdwebo obandayo, futhi ikakhulukazi esetshenziswa njengamapayipi noma izingxenye zesakhiwo ukuthutha uketshezi.
Uhlobo lweshubhu elingunxande elingenamthungo:
1. Ngokusho kwempahla, ingahlukaniswa ngensimbi evamile yesakhiwo se-carbon kanye ne-alloy ephansi yamandla aphezulu ensimbi yesakhiwo. I-carbon content yangaphambili akumele idlule ku-4.5%; isulfure ≤ 0.035; i-phosphorus ≤ 0.005; i-chromium ≤ 0.15; okuqukethwe kwe-nickel <0,25; ithusi ≤ 0.30; Lesi sakamuva siqukethe inani elincane le-silicon, i-manganese ne-vanadium ngaphezu kwe-carbon, isulfure, i-phosphorus ne-chromium.
2. Ngokusho kwekhwalithi yendawo:
(1) Qeda:
1 Indawo yangaphakathi nengaphandle yeshubhu yesikwele engenamthungo izoba bushelelezi futhi isicaba ngaphandle kwamabhamuza nemibimbi.
2 Lapho indawo yangaphakathi yangaphakathi ingaphansi kuka-100 mm2, ukubekezelelana okuvumelekile kwendawo yangaphakathi kungu-± 0.2 mm.
3 Lapho indawo yangaphakathi yangaphakathi ingaphezu kuka-100 mm2, ukubekezelelana okuvumelekile kwendawo yangaphakathi kungu-± 0.5 mm.
4 Akukho mifantu noma ukugoqa okuvunyelwe endaweni engaphakathi; 5 Ngeke kube khona isibazi 6 Akukho mihuzuko esobala nemivimbo.
(2) Ukucaba:
1 Indawo yangaphakathi neyangaphandle yamashubhu ayisikwele angenamthungo kufanele ibe isicaba futhi ibushelelezi.
2 Akumele kube khona ukungalingani okusobala uma kubonwa ngengilazi yokukhulisa engu-10X.
3 Ubuso bokugcina bombhobho bubheke emgqeni ophakathi wepayipi.
4 Ubuso bokuphela kwendawo yepayipi ngeke bube nama-burrs.
5 Akuyikuba khona ukushwabana ejikeni lombhobho.
6 Imikhawulo yomibili yepayipi kufanele ihambisane.
7 Akukho qhuqhuva elisobala elivunyelwe ekushiseleni ngemva kokususwa kokugqwala.
8 Akufanele kube khona imigodi esobala.
9 Awekho amaphutha athinta ukusetshenziswa avunyelwe.
10 Lapho umshini wokugoqa ipuleti usetshenziselwa ukushisela, i-fillet radius ekushiseleni akufanele ibe ngaphansi kogqinsi lwesisekelo sensimbi.
(3) Ukunemba kobukhulu:
1 Iphutha eliyindingilizi akumele leqe ukuchezuka okuphezulu okushiwo ezingeni elihambisanayo ngaphezu kuka-2 mm/m2.
2 Ukuqonda nokuchezuka kwe-engeli akumele kudlule u-1/20 wokuchezuka okuphezulu okushiwo ezingeni elihambisanayo.
3 Ukuchezuka komkhawulo wobude akumele kube kukhulu kunezikhathi ezingu-1.5 yenani elicacisiwe elihambisanayo.
Ukulawulwa kwekhwalithi yeipayipi yensimbi ye-yuantaiiqinile kakhulu, ngakho amakhasimende angakhetha ngokuzethemba.Inkampani ye-YuantaiUthole amalungelo obunikazi angama-77,Insimbi ye-Yuantaiuwine umpetha oyedwa wemboni yeshubhu elingunxande iminyaka eyi-10 ilandelana,
Uma udinga ukutholaintengo yepayipi yensimbi ye-yuantai,Sicela usithinte.
