Amapayipi ensimbi angenamthungo

Amapayipi ensimbi angenamthungo

Amapayipi ensimbi engenamthungo akhiwe ngengxenye yensimbi, futhi akukho mthungo ebusweni. Babizwa ngokuthi amapayipi ensimbi engenamthungo. Ngokwendlela yokukhiqiza, amapayipi angenamthungo ahlukaniswe ngamapayipi asongwe amaphayiphu, amapayipi adonswe amakhaza, amapayipi adonswayo, amapayipi akhishwe, amapayipi e-njr. Ngokwesigaba sensimbi ahlukaniswe yi-Round futhi Amapayipi akhethekile abunjiwe. Amapayipi abunjiwe okhethekile anesikwele, i-oval, unxantathu, i-hexagon, i-melon imbewu, inkanyezi, amapayipi anamaphiko nezinye izinhlobo eziningi eziyinkimbinkimbi. Ububanzi obukhulu bungama-650mm kanti ububanzi obuncane bungu-0.3mm. Ngokuya ngokusetshenziswa okuhlukile, kukhona amapayipi abiyelwe ngodonga onke kanye namapayipi amancanyana. Amapayipi ensimbi angenamthungo asetshenziswa ikakhulukazi njengamapayipi okumba we-petroleum geological, amapayipi okuqhekeka kwama-petrochemicals, amapayipi e-boiler, amapayipi anembe okuphezulu, kanye namapayipi entengo aphezulu aphezulu wezimoto, ogandaganda kanye nendiza. Ipayipi lensimbi ngaphandle kwemithumo eceleni kwengxenye yesigaba sayo sesiphambano. Ngokwezindlela ezahlukene zokukhiqiza, ihlukaniswe ngamapayipi asongwe amapayipi avuthayo, amapayipi adonswe amakhaza, amapayipi adonswe amakhaza, amapayipi akhishwe, amapayipi akhishwe, njll., Zonke ngemithetho yazo yenqubo. Izinto ezisetshenziswayo zifaka insimbi ejwayelekile nekhwalithi ephezulu yekhabhoni (Q215-A ~ Q275-a kanye ne-10 ~ 50 insimbi), i-alloy yensimbi ephansi (i-alloy yensimbi, njll yensimbi engasho lutho, njll. Ukusetshenziswa, ihlukaniswe ngokusetshenziswa okujwayelekile (okusetshenziselwa amanzi, amapayipi wegesi kanye nezingxenye zokwakheka, izingxenye zemishini) nokusetshenziswa okukhethekile (ukuhlola kwe-boolical, amabele, ukumelana ne-acid, njll.). Inqubo enkulu yokukhiqiza yepayipi lensimbi eshisayo eshisayo (△ inqubo enkulu yokuhlola):
Ukulungiswa Okungenalutho Kokungenalutho kanye nokuhlola △ → Ukushisa okungenalutho okulula → Ukugcina
Inqubo enkulu yokukhiqiza ye-Cold-Roll-Rolling (Drawn) Steamless Pipe yensimbi engenamthungo
Ukulungiswa okungenalutho → Ukukhanyisa i-acid nokuthambisa
Inqubo yokukhiqiza yensimbi ejwayelekile yensimbi ingahlukaniswa yaba umdwebo obandayo nokugoqa okushisayo. Inqubo yokukhiqiza yepayipi lensimbi elibandayo elibandayo ngokuvamile iyinkimbinkimbi ngokwedlula ukugingqa okushisayo. Ipayipi lingenalutho kumele liqale ligoqwe ngama-roller amathathu, bese kuthi ukuhlolwa kokuhlaziywa kwesayizi ngemuva kokukhishwa. Uma kungekho ukuqhekeka kwempendulo ebusweni, ipayipi eliyindilinga kufanele linqunywe ngumshini wokusika bese lisika kwi-billet yemitha eyodwa ubude. Bese ufaka inqubo yokunxusa. I-Anneling kumele ifakwe ngoketshezi olune-acidic. Lapho ukhetha, naka ukunaka ukuthi ngabe kunenani elikhulu lama-bubble ebusweni. Uma kunenani elikhulu lama-bubble, kusho ukuthi ikhwalithi yepayipi lensimbi ayihlangabezani namazinga ahambisanayo. Ngokubukeka, amapayipi ensimbi agobhoziwe angenawo amafushane anamapayipi ensimbi ashushululewe. Ukuqina kodonga kwamapayipi ensimbi agoqwe abandayo ngokuvamile kuncane kunalokho amapayipi ensimbi angenayo, kepha ingaphezulu libukeka likhanya ngaphezu kwamapayipi ensimbi angenawo angenawo afakwe emthungo, kanti ingaphezulu alikhangi kakhulu, futhi ububanzi abunayo ama-burrs amaningi kakhulu.
Isimo sokulethwa kwamapayipi ensimbi asongelwe esishisayo ngokuvamile asongelwa futhi aphathwe ukushisa ngaphambi kokulethwa. Ngemuva kokuhlolwa kwekhwalithi, amapayipi ensimbi agoqwa ngokushisayo kufanele akhethwe ngokuqinile ngabasebenzi, futhi ingaphezulu komhlaba kufanele lifakwe kumafutha ngemuva kokuhlolwa kwekhwalithi, kulandelwe ukuhlolwa okuningi kokudweba okubandayo. Ngemuva kokwelashwa okushisayo okushisayo, ukuhlolwa kokunye kumele kwenziwe. Uma ububanzi be-vocate bukhulu kakhulu, ukuqondisa nokulungiswa kumele kwenziwe. Ngemuva kokuqondisa okuqondile, idivaysi yokuhambisa izodluliselwa kumshini wephutha wokutholwa kwe-fine, futhi ekugcineni ilebula, ihlelwe ngokucaciswa, futhi ibekwe endaweni yokugcina izinto.
I-Round Tube Billet → Ukushisa → Ukufushanisa → Ukugoqa okuthathu okuxakile, ukukhishwa okuqhubekayo noma ukuncishiswa kwe-tube (noma ukuncishiswa kwe-ture → yensimbi ye-ingot noma i-tube eqinile nge-tube ye-tube enolaka, bese yenziwa ngokugoqa okushisayo, okubandayo noma umdwebo obandayo. Ukucaciswa kwepayipi lensimbi engenamthungo kuvezwa kumamilimitha we-outer ububanzi * ukushuba udonga.
Ububanzi obungaphandle bepayipi elingenamthungo elishisayo ngokuvamile bukhulu kune-32mm, futhi ubukhulu bodonga bungu-2,5-200mm. Ububanzi obungaphandle bepayipi lensimbi elibandayo elibandayo bungafinyelela ku-6mm, ukushuba odongeni kungafinyelela ku-0.25mm, kanye nobubanzi obungaphandle kwepayipi elibiwe elincanyana kungafinyelela ku-5mm kanye nodonga olungaphansi kuka-0.25mm. Ukuqhakaza okubandayo kunokunemba okuphezulu okuphezulu kunokugoqa okushisayo.
Ngokuvamile, amapayipi ensimbi angenamthungo enziwe nge-10, 20, 30, 35 I-Carbon Steel ephezulu, i-16mn, 5MNV kanye nezinye zensimbi enokwakheka okuphansi noma i-40mm2, 40MNB kanye nezinye izinsimbi ze-alloy. Ukugoqa okushisayo noma okubandayo okubandayo. Amapayipi angenamthungo enziwe ngensimbi ephansi yekhabhoni efana ne-10 no-20 asetshenziselwa amapayipi okulethwa koketshezi. Amapayipi angenamthungo enziwe ngensimbi ephakathi yekhabhoni enjenge-45 ne-40cr asetshenziselwa ukukhiqiza izingxenye zemishini, njengezingxenye ezithwala umthwalo wezimoto kanye nogandaganda. Ngokuvamile, amapayipi ensimbi angenamthungo kufanele aqinisekise amandla nezivivinyo ezivuthayo. Amapayipi ensimbi asongwe ahanjiswa ezifundeni ezivusene noma eziphathwa ukushisa; Amapayipi ensimbi ebandayo alethwa ezifundeni eziphathwa ukushisa.
Ukujikeleza okushisayo, njengoba igama lisho, linokushisa okuphezulu kwengcezu egoqiwe, ngakho-ke ukumelana nokuchazwa kuncane futhi inani elikhulu lokukhubazeka lingatholakala. Ukuthatha ukugoqa amapuleti ensimbi njengesibonelo, ukushuba kwe-billet eqhubekayo yokuphonsa ngokuvamile cishe ngo-230mm, nangemva kokugqwala okunzima nokuqedwa kokuqeda, ubukhulu bokugcina buyi-1 ~ 20mm. Ngasikhathi sinye, ngenxa yesilinganiso esincane sobubanzi-kuya-ukuqina kwepuleti lensimbi, izidingo zokunemba ezinobukhulu ziphansi, futhi akulula ukuba nezinkinga zokwakheka kwepuleti, ikakhulukazi ukulawula ukwakheka. Kulabo abanezidingo zenhlangano, kutholakala ngokuvamile ngokupholisa okulawulwayo nokupholisa okulawulwayo, okungukuthi, ukulawula amazinga okushisa okushisa okuqala kanye nokushisa kokugcina kokuqedwa kokuqeda.
