I-Precision Steel Pipe, Izici Zomkhiqizo
1. I-diameter yangaphandle encane.
2. Ukunemba okuphezulu kungenza ukukhiqizwa kwenqwaba encane
3. Imikhiqizo edonswa ngokubanda inokunemba okuphezulu kanye nekhwalithi enhle yangaphandle.
4. Indawo yesiphambano sepayipi yensimbi iyinkimbinkimbi kakhulu.
5. Ukusebenza kwepayipi yensimbi kuphakeme, futhi insimbi iminyene.
Izindlela Zokukhiqiza Nezokukhiqiza
Ngokwezindlela ezihlukene zokukhiqiza, ingahlukaniswa ibe ithubhu eligoqiwe elishisayo, ishubhu eligoqiwe elibandayo, ishubhu elidonswa ngokubanda, ishubhu le-extrusion nokunye.
1.1 Amapayipi angenamthungo agingqiwe ashisayo ngokuvamile akhiqizwa kumasethi amapayipi azenzakalelayo.Ishubhu elingenalutho elingenalutho liyahlolwa futhi lisuswe ukukhubazeka okungaphezulu, lisikwe kubude obudingekayo, ligxile ekugcineni kobuso obunezimbobo beshubhu elingenalutho, bese lithunyelwa esithandweni sokushisa ukuze lishiswe, futhi limbozwe emshinini wokubhoboza.Ekubhobozeni ngesikhathi esifanayo ukujikeleza okuqhubekayo naphambili, ngaphansi kwesenzo somqulu nangaphezulu, ishubhu elingenalutho kancane kancane lakha umgodi, obizwa ngokuthi ishubhu loboya.Bese ithunyelwa emshinini wokugaya amapayipi ukuze iqhubeke nokugingqika.Ekugcineni, ubukhulu bodonga lomshini wonke buyalungiswa, futhi umshini wokulinganisa uyalungiswa ukuze uhlangabezane nezidingo zokucaciswa.Kuyindlela ethuthukisiwe yokukhiqiza ishubhu yensimbi engenamthungo eshisayo egoqiwe enesethi yeshubhu egoqayo eqhubekayo.
1.2 Uma ufuna ukuthola amashubhu angenamthungo anosayizi omncane kanye nekhwalithi engcono, kufanele usebenzise ukugoqa okubandayo, umdwebo obandayo noma inhlanganisela yazo zombili izindlela.Ukugoqa okubandayo kuvame ukwenziwa emshinini ophakeme kabili.Ipayipi lensimbi ligoqwe ku-annular pass ehlanganisa i-groove eyindilinga enesigaba esiguquguqukayo kanye ne-conical top emile.Umdwebo obandayo uvame ukwenziwa ngo-0.5 ~ 100T weketanga elilodwa noma umshini wokudweba obandayo wamaketanga amabili.
1.3.Indlela ye-Extrusion: Ishubhu elishisayo elingenalutho lifakwa kusilinda esivaliwe, futhi induku enembobo ihamba kanye ne-extrusion rod ukuze ikhiphe izingxenye ezikhishwe emgodini omncane wokufa.Le ndlela ingakhiqiza ipayipi lensimbi elincane lobubanzi.
Precision Steel Pipe, Sebenzisa
2.1, ipayipi elingenamthungo lisetshenziswa kabanzi.Inhloso evamile ipayipi elingenamthungo ngensimbi evamile ye-carbon structural, insimbi yesakhiwo se-alloy ephansi noma i-alloy structural steel rolling, ukukhiqizwa yiyona kakhulu, ikakhulukazi esetshenziselwa ukudlulisa amapayipi oketshezi noma izingxenye zesakhiwo.
2.2.Nikeza ngezigaba ezintathu ngokusetshenziswa okuhlukene: a.Ukuhlinzeka ngokuhambisana nokwakheka kwamakhemikhali kanye nezakhiwo zemishini;B. Ukuhlinzeka ngokuhambisana nezakhiwo zemishini;C. Nikeza ngokokuhlolwa komfutho wamanzi.Amashubhu ensimbi ahlinzekwa ngaphansi kwekilasi A kanye ne-CLASS B, uma esetshenziselwa ukumelana nokucindezela koketshezi, nawo angaphansi kokuhlolwa kwe-hydrostatic.
2.3, ukusetshenziswa okukhethekile kweshubhu elingenamthungo le-tube boiler elingenamthungo, ithubhu ye-geological seamless kanye neshubhu engenamthungo kawoyela, njll.
