Amapayipi ensimbi angenamthungo

Amapayipi ensimbi angenamthungo

Amapayipi ensimbi angenamthungo enziwe ngensimbi yonke, futhi awekho ama-seams ebusweni. Abizwa ngamapayipi ensimbi angenamthungo. Ngokwendlela yokukhiqiza, amapayipi angenamthungo ahlukaniswe abe amapayipi agoqelwe ashisayo, amapayipi abandayo, amapayipi adonswa abandayo, amapayipi akhishwe ngaphandle, amapayipi aqhumayo, njll. Ngokusho kokuma kwe-cross-sectional, amapayipi ensimbi angenamthungo ahlukaniswa abe yindilinga futhi amapayipi amise okukhethekile. Amapayipi amise okwesipesheli anesikwele, i-oval, unxantathu, i-hexagon, imbewu ye-melon, inkanyezi, amapayipi anamaphiko nezinye izimo eziningi eziyinkimbinkimbi. Ubukhulu obukhulu bungama-650mm kanti ubuncane be-diameter bungu-0.3mm. Ngokusetshenziswa okuhlukene, kunamapayipi anezindonga eziwugqinsi namapayipi anezindonga ezincane. Amapayipi ensimbi angenamthungo asetshenziswa kakhulu njengamapayipi okumba i-petroleum geological, amapayipi aqhekeka amakhemikhali kaphethiloli, amapayipi abhayela, amapayipi anamanzi, namapayipi ensimbi anesakhiwo esinembayo esiphezulu ezimoto, ogandaganda, kanye nezokundiza. Ipayipi lensimbi elingenayo imithungo eduze komphetho wengxenye yalo ephambanayo. Ngokwezindlela ezihlukene zokukhiqiza, ihlukaniswe ngamapayipi ashisayo, amapayipi abandayo, amapayipi adonswa ngamakhaza, amapayipi akhishwe ngaphandle, amapayipi e-jacking, njll., zonke zinemithethonqubo yazo. Izinto ezisetshenziswayo zifaka insimbi yesakhiwo sekhabhoni ejwayelekile nesezingeni eliphezulu (Q215-A~Q275-A nensimbi engu-10~50), insimbi yengxubevange ephansi (09MnV, 16Mn, njll.), insimbi yengxubevange, insimbi engagqwali engamelana ne-asidi, njll. Ngokusho ekusetshenzisweni, ihlukaniswe ngokujwayelekile (isetshenziselwa amanzi, amapayipi egesi kanye nezingxenye zesakhiwo, izingxenye zemishini) nokusetshenziswa okukhethekile (okusetshenziselwa ama-boilers, ukuhlola i-geological, ama-bearings, ukumelana ne-asidi, njll.). ① Inqubo yokukhiqiza eyinhloko yepayipi lensimbi engenamthungo egoqelwe ngokushisayo (△ Inqubo yokuhlola enkulu):
Ukulungiswa kwepayipi elingenalutho nokuhlola△→Ukushisisa okungenalutho kwepayipi→Ukubhobozwa kwepayipi→Ukugoqeka kwepayipi→Ukushisisa kabusha kwepayipi lensimbi→Usayizi (ukunciphisa)→Ukwelashwa kokushisa△→Ukuqondisa amapayipi okuqediwe→Ukuqeda→Ukuhlola△(Ukuhlola okungalimazi, okubonakalayo namakhemikhali, ukuhlola ibhentshi) →Ukugcinwa kwempahla
② Inqubo yokukhiqiza eyinhloko yepayipi lensimbi eligoqiwe (elidwetshiwe) elingenamthungo: Ipayipi lensimbi engenamthungo_ Umkhiqizi wamapayipi ensimbi angenamthungo_Intengo yepayipi lensimbi engenamthungo
Ukulungiselela okungenalutho→Ukukha i-asidi nokugcobisa→Ukugoqa okubandayo (umdwebo)→Ukwelashwa kokushisa→Ukuqondisa→Ukuqeda→Ukuhlola
Inqubo evamile yokukhiqiza ipayipi lensimbi engenamthungo ingahlukaniswa ngomdwebo obandayo kanye nokuginqika okushisayo. Inqubo yokukhiqiza ipayipi lensimbi elingenamthungo eligoqiwe ngokubanda ngokuvamile liyinkimbinkimbi kakhulu kunokuginqika okushisayo. Ipayipi elingenalutho kufanele liqale ligoqwe ngama-roller amathathu, bese ukuhlolwa kokulinganisa kufanele kwenziwe ngemuva kokukhishwa. Uma kungekho ukuqhekeka kwempendulo ebusweni, ipayipi eliyindilinga kufanele lisikwe ngomshini wokusika futhi lisikwe ku-billet cishe imitha eyodwa ubude. Bese ufaka inqubo yokudonsa. I-Annealing kufanele ifakwe emanzini ane-asidi. Lapho ukhetha, qaphela ukuthi kukhona inani elikhulu lama-bubble ebusweni. Uma kukhona inani elikhulu lama-bubbles, kusho ukuthi ikhwalithi yepayipi yensimbi ayihlangabezani nezindinganiso ezihambisanayo. Ngokubukeka, amapayipi ensimbi angenamthungo agoqelwe ngamakhaza mafushane kunamapayipi ensimbi angenamthungo agingqiwe ashisayo. Ugqinsi lwamapayipi ensimbi angenamthungo agoqelwe ngokubanda ngokuvamile mancane kunalawo amapayipi ensimbi angenamthungo agingqiwe ashisayo, kodwa indawo engaphezulu ibukeka icwebezela kunamapayipi ensimbi aqinile anezindonga eziqinile, futhi ingaphezulu alibi kakhulu, futhi ububanzi abunawo. ama-burrs amaningi kakhulu.
Isimo sokulethwa kwamapayipi ensimbi engenamthungo agingqiwe ashisayo ngokuvamile ayashiswa futhi aphathwe ngokushisa ngaphambi kokulethwa. Ngemva kokuhlolwa kwekhwalithi, amapayipi ensimbi angenamthungo agingqiwe ashisayo kufanele akhethwe ngesandla ngokuqinile ngabasebenzi, futhi indawo engaphezulu kufanele igcotshwe ngemva kokuhlolwa kwekhwalithi, kulandelwe ukuhlolwa okuningi kokudweba okubandayo. Ngemuva kokwelashwa kwe-hot rolling, ukuhlolwa kwe-perforation kufanele kwenziwe. Uma ububanzi be-perforation bukhulu kakhulu, ukuqondisa nokulungiswa kufanele kwenziwe. Ngemva kokuqondisa, umshini wokudlulisa uzodluliselwa kumtshina onamaphutha ukuze kutholwe amaphutha, futhi ekugcineni ulebulwe, uhlelwe ngokucaciswa, bese ufakwa endaweni yokugcina impahla.
I-tube billet eyindilinga → ukushisa → ukubhobozwa → ukugoqeka okutshekile kwamarola amathathu, ukugingqika okuqhubekayo noma okuphumayo → ukususwa kweshubhu → ukusika (noma ukunciphisa ububanzi) → ukupholisa → ukuqondisa → ukuhlolwa komfutho we-hydraulic (noma ukutholwa kwamaphutha) → ukumaka → indawo yokugcina ipayipi lensimbi engenamthungo yensimbi yensimbi noma i-billet yeshubhu eqinile ngokubhoboza ibe yishubhu elimaholoholo, bese lenziwa ngokuginqika okushisayo, ukugoqa okubandayo noma umdwebo obandayo. Ukucaciswa kwepayipi lensimbi engenamthungo kuvezwa ngamamilimitha obubanzi obungaphandle * ukujiya kodonga.
Ububanzi bangaphandle bepayipi elingenamthungo eligoqwe elishisayo ngokuvamile bukhulu kuno-32mm, futhi ukujiya kodonga kungu-2.5-200mm. Ububanzi bangaphandle bepayipi lensimbi elingenamthungo eligoqwe ngokubanda lingafinyelela ku-6mm, ukujiya kodonga bungafinyelela ku-0.25mm, kanti ububanzi bangaphandle bepayipi elinezindonga ezincane bungafinyelela ku-5mm kanti ukujiya kodonga kungaphansi kuka-0.25mm. Ukugoqa okubandayo kunokunemba okuphezulu kunokulinganisa okushisayo.
Ngokuvamile, amapayipi ensimbi angenamthungo enziwe ngensimbi ye-carbon steel engu-10, 20, 30, 35, 45 yekhwalithi ephezulu, i-16Mn, 5MnV nezinye insimbi yesakhiwo esine-alloy ephansi noma i-40Cr, 30CrMnSi, 45Mn2, 40MnB nezinye izinsimbi ze-alloy. Ukugoqa okushisayo noma ukugoqa okubandayo. Amapayipi angenamthungo enziwe ngensimbi enekhabhoni ephansi efana no-10 no-20 asetshenziselwa ikakhulukazi amapayipi okulethwa koketshezi. Amapayipi angenamthungo enziwe ngensimbi ye-carbon steel ephakathi njengo-45 no-40Cr asetshenziselwa ukwakha izingxenye zemishini, njengezingxenye ezithwala umthwalo wezimoto nogandaganda. Ngokuvamile, amapayipi ensimbi angenamthungo kufanele aqinisekise ukuqina nokuhlolwa okucaba. Amapayipi ensimbi agoqwe ngokushisa alethwa ezindaweni ezishisayo noma eziphethwe ukushisa; amapayipi ensimbi abandayo ahanjiswa ezifundeni eziphethwe ukushisa.
Ukugoqa okushisayo, njengoba negama lisho, kunokushisa okuphezulu kwesiqephu esigoqiwe, ngakho-ke ukumelana ne-deformation kuncane futhi inani elikhulu le-deformation lingafinyelelwa. Uma sithatha ukugingqika kwamapuleti ensimbi njengesibonelo, ukujiya kwe-billet eqhubekayo yokuphonsa ngokuvamile kungaba ngu-230mm, futhi ngemva kokugingqa nokuqeda ukugoqa, ukujiya kokugcina kungu-1~20mm. Ngesikhathi esifanayo, ngenxa yesilinganiso esincane sobubanzi nobukhulu bepuleti lensimbi, izidingo zokunemba kwe-dimensional ziphansi kakhulu, futhi akulula ukuba nezinkinga zokuma kwepuleti, ikakhulukazi ukulawula ukuguquguquka. Kulabo abanezidingo zenhlangano, ngokuvamile kufinyelelwa ngokugingqeka okulawulwayo kanye nokupholisa okulawulwayo, okungukuthi, ukulawula izinga lokushisa eliqala ukugoqwa kanye nezinga lokushisa lokugcina lokuginqika lokupholisa. I-tube billet eyindilinga → ukushisa → ukubhoboza → isihloko → ukudonsa → ukukhetha → ukugcoba amafutha (i-copper plating) → amaphasi amaningi omdwebo obandayo (ukugoqa okubandayo) → ishubhu le-billet → ukwelashwa kokushisa → ukuqondisa → ukuhlolwa kwengcindezi yamanzi (ukutholwa kwamaphutha) → ukumaka → isitoreji.
