I-Wholesale ASTM 1020 Quilted steel pipe
Ukucubungula Ubuchwepheshe
Ipayipi lensimbi elihlanganisiwe licutshungulwa ngokugoqa.Ngenxa yengcindezi esele yokucindezela phezu kongqimba olungaphezulu, kuyasiza ukuvala imifantu emincane ebusweni futhi kuvinjwe ukwanda kokuguguleka.Ukuze kuthuthukiswe ukumelana nokugqwala kwendawo futhi kubambezele ukukhiqizwa noma ukunwetshwa kwemifantu yokukhathala, ukuze kuthuthukiswe amandla okukhathala kwepayipi lensimbi elicijile.Ngokwenza ukugoqa, kwakheka ungqimba oluqinile lomsebenzi obandayo endaweni egoqayo, okunciphisa ukuwohloka kwe-elastic kanye nepulasitiki yendawo yokuxhumana yepheya yokugaya, ithuthukise ukumelana nokugqokwa kodonga lwangaphakathi lwepayipi lensimbi elicijile, futhi igweme ukushiswa. okubangelwa ukugaya.Ngemuva kokugoqa, ukuncishiswa kokuqina kwendawo kungathuthukisa izakhiwo ezihambisanayo.
I-Rolling iwuhlobo lokucutshungulwa kwamahhala kwe-chip, olusebenzisa i-deformation ye-plastic yensimbi ekamelweni lokushisa ukuze kuncishiswe ukungalingani okuncane kwendawo yokusebenza, ukuze kuguqulwe isakhiwo esingaphezulu, izici zemishini, ukwakheka nosayizi.Ngakho-ke, le ndlela ingafinyelela izinhloso ezimbili zokuqeda nokuqinisa ngesikhathi esifanayo, ezingenakufinyelelwa ngokugaya.
Kungakhathaliseki ukuthi iyiphi indlela yokucubungula esetshenziswayo, amamaki emimese amahle angalingani ayohlala eshiywe phezu kwezingxenye, okuholela eziqongweni ezinyakazayo nezigodi,
Isimiso sokucubungula ukugoqa: kuwuhlobo lokuphothula ingcindezi, olusebenzisa izici zepulasitiki ezibandayo zensimbi ekamelweni lokushisa futhi lufake ingcindezi ethile endaweni yokusebenza ngamathuluzi okugoqa ukwenza insimbi endaweni yokusebenza ikhiqize ukugeleza kwepulasitiki bese uyigcwalisa. ungene emkhombeni wokuqala oyinsalela ophansi we-concave, ukuze kwehliswe inani lokumatsheka kwendawo yokusebenza.Ngenxa yokuguqulwa kwepulasitiki yensimbi engaphezulu egoqwe, isakhiwo esingaphezulu siyabanda futhi okusanhlamvu kuyaba kuhle, kwakha umumo ominyene we-fibrous, kwakha ungqimba olusele lokucindezeleka, nokuthuthukisa ubulukhuni namandla, ukuze kuthuthukiswe ukumelana nokugqokwa, ukumelana nokugqwala nokuhambisana kwendawo yokusebenza.Ukugoqa kuyindlela yokwenza ipulasitiki ngaphandle kokusika.
Ukucubungula Izinzuzo
1. Thuthukisa ubuso obumangelengele, futhi ubulukhuni bungafinyelela ku-RA ≤ 0.08 & micro;M noma kunjalo.
2. Ukujikeleza okulungisiwe, i-ovality ingaba ≤ 0.01mm.
3. Thuthukisa ubulukhuni bobuso, susa ukuwohloka kokucindezeleka, futhi wandise ubulukhuni nge-HV ≥ 4.
4. Kukhona ungqimba olusele lokucindezeleka ngemva kokucubungula, futhi amandla okukhathala akhuphuka ngo-30%.
5. Thuthukisa ikhwalithi efanayo, unciphise ukuguga futhi unwebe impilo yesevisi yezingxenye, kodwa izindleko zokucubungula izingxenye ziyancipha.
Umehluko
Umehluko phakathi kwepayipi lensimbi elihlanganisiwe nepayipi lensimbi engenamthungo
1. Isici esiyinhloko sepayipi yensimbi engenamthungo ayikho i-welding joint, engakwazi ukumelana nokucindezela okukhulu.Umkhiqizo ungaba nzima kakhulu njengezingxenye ezikhandiwe noma ezibandayo.
2. Quilted steel pipe umkhiqizo uvele eminyakeni yamuva, okuyinto ngokuyinhloko has ukubekezelelana okuqinile futhi emangelengele for izilinganiso imbobo elingaphakathi nodonga lwangaphandle.
Izici zepayipi lensimbi elicijile
1. Ububanzi obuncane obungaphandle.
2. Ukunemba okuphezulu futhi kungakhiqizwa ngenqwaba encane
3. Imikhiqizo edonswa ngokubanda inokunemba okuphezulu kanye nekhwalithi enhle yendawo.
4. Indawo yesiphambano sepayipi yensimbi iyinkimbinkimbi kakhulu.
5. Ipayipi lensimbi linokusebenza okuphakeme kanye nensimbi eminyene.
Umehluko Ngemva Kwe-Hot Rolling Quilted Steel Pipe
Ipayipi lensimbi elinembe eligoqelwe ngokushisayo lisebenzisa i-slab eyindilinga eyindilinga eqhubekayo noma i-bloom slab njengempahla eluhlaza, eshiswa isithando sokushisa esinyathelayo futhi yehliswe ngamanzi anomfutho omkhulu ngaphambi kokungena emshinini wokugaywa.I-roughing material ingena emshinini wokuqedela ngemva kokusika, ukumsila bese ingena emshinini wokuqedela wekhompyutha {i-controlled rolling.Ngemva kokugoqeka kokugcina, igoqwa ibe ikhoyili yezinwele eziqondile ngokusebenzisa ukupholisa i-laminar kanye nekhoyili.Ikhanda nomsila we-curl yezinwele eziqondile kuvame ukwakheka kolimi kanye nomsila we-fishtail, ngokunganembi kahle kokuqina nobubanzi, futhi kuvame ukuba namaphutha afana nokuma kwegagasi, umphetho, ukwakheka kombhoshongo nokunye.Isisindo sekhoyili sikhulu futhi ububanzi bangaphakathi bekhoyili bungama-760mm.Ngemuva kokuthi ikhoyili yezinwele eziqondile icutshungulwe ngokusikwa kwekhanda, ukusika umsila, ukusika onqenqemeni, ukuqondisa ama-multi pass, ukulinganisa neminye imigqa yokuqedela, iyasikwa noma iphinde ihlanganiswe ukuze ibe ipuleti lensimbi eligoqiwe elishisayo, ikhoyili yensimbi egoqelwe eyisicaba, ukusika ubude. ibhande neminye imikhiqizo.Uma ikhoyili yokuqedela egoqwe ngokushisayo ifakwe emanzini ukuze isuse isikali se-oxide futhi igcotshwe ngamafutha, izoba ikhoyili efakwe emanzini ashisayo.
