I-Original Factory A53 A333 A106 St45 Sch40 DN15 Q235B Q355b API 5L Ikhabhoni Emnyama Eminyene Udonga Olukhulu Olubandayo Oludwetshwe Kuvunguza Olungenamthungo/Igalatiyela/Eshiselwe/I-Precision Steel Tube/Pipe.

Incazelo emfushane:

Ipayipi elishiselwe nge-Spiral: Lenziwe ngensimbi enekhabhoni ephansi ene-carbon structural steel noma i-low-alloy structural steel strip egingqelwa ku-billet yepayipi nge-engeli ethile yomugqa ovunguzayo (okuthiwa i-engeli yokwakha), bese umthungo wepayipi ushiselwa ndawonye, ingakhiqiza ipayipi elikhulu lensimbi elisuka ku-strip ewumngcingo.Ukucaciswa kwayo kuvezwa ubukhulu bangaphandle * bezindonga, ipayipi elishiselwe kufanele liqinisekise ukuthi ukuhlolwa kwe-hydraulic, amandla aqinile we-weld kanye nezakhiwo zokugoba ezibandayo ukuhlangabezana nezinhlinzeko.

Omaka bomkhiqizo

Sithembela ekucabangeni kwamasu, ukwenza izinto zibe zesimanjemanje kuzo zonke izingxenye, intuthuko yezobuchwepheshe kanye nakubasebenzi bethu ababamba iqhaza ngokuqondile empumelelweni yethu ye-Original Factory A53 A333 A106 St45 Sch40 DN15 Q235B Q355b API 5L Carbon Black Thick Wall Large Diameter Coldless Drawn/Spiral Seam Galvanized/Welded/Precision Steel Tube/Pipe., Siphikelela ukuthuthukisa umoya wethu webhizinisi “ikhwalithi iphila ibhizinisi, isikweletu siqinisekisa ukubambisana futhi sigcina isiqubulo ezingqondweni zethu: amakhasimende kuqala.
Sithembele ekucabangeni kwamasu, ukwenza ngcono okuqhubekayo kuzo zonke izingxenye, intuthuko yezobuchwepheshe kanye nakubasebenzi bethu ababamba iqhaza ngokuqondile empumelelweni yethuI-China Precision Steel Tube kanye ne-Precision Steel Pipe, Sizuze idumela elihle phakathi kwamakhasimende aphesheya nasekhaya.Ngokubambelela enkambisweni yokuphatha “yokuthambekela kwezikweletu, ikhasimende kuqala, ukusebenza kahle okuphezulu namasevisi akhulile”, samukela ngokufudumele abangane abavela kuzo zonke izigaba zokuphila ukuze babambisane nathi.

Izakhiwo ze-Metallurgical zezinto

Amapayipi ashiselwe i-arc angaphansi kwamanzi amade akhiqizwa ngamapuleti ensimbi, kuyilapho amapayipi ashiselwe okugobile akhiqizwa ngamakhoyili agingqiwe ashisayo.Inqubo yokugingqa iyunithi ye-hot-rolled inezinzuzo eziningi futhi inamandla enqubo ye-metallurgical ukuthola ukukhiqizwa kwensimbi yomugqa wamapayipi wekhwalithi ephezulu.Isibonelo, ukuma okukhiphayo kufakwe isistimu yokupholisa amanzi ukusheshisa ukupholisa, okuvumela ukusetshenziswa kwezingoma ze-alloy ephansi ukuze kuzuzwe amamaki akhethekile wamandla kanye nokuqina okuphansi kwezinga lokushisa, ngaleyo ndlela kuthuthukiswe ukushisela kwensimbi.Kodwa-ke, lolu hlelo alukho kakhulu ezitshalweni zokukhiqiza amashidi ensimbi.Okuqukethwe kwe-alloy (okulingana nekhabhoni) kwamakhoyili kuvame ukuba ngaphansi kunalawo amamaki afanayo amapuleti ensimbi, aphinde athuthukise ukushisela kwamapayipi ashiselwe okuvunguzayo.

Okubaluleke nakakhulu ukuthi ukuqaphela ukuthi, ngenxa yokuthi ipayipi elishiselwe ukugoqa ikhoyili aliqondani nesiqondiso se-axis yepayipi lensimbi (isixazululo salo sokuncisha sincike engeli elivunguzayo lepayipi lensimbi), kuyilapho ipayipi lensimbi lomthungo oqondile ligingqika. isiqondiso perpendicular isiqondiso eksisi yepayipi lensimbi, futhi kanjalo, Kuvunguza ashiselwe ipayipi impahla ingcono kunomphetho oqondile steel ipayipi ukuqhekeka ukumelana.

Inqubo yokushisela

Kusukela inqubo yokushisela, Kuvunguza ashiselwe ipayipi kanye umthungo steel ipayipi welding indlela efanayo, kodwa umthungo oqondile ipayipi ashiselwe nakanjani uyoba eziningi weld weld, ngakho amathuba Welding amaphutha anda kakhulu, futhi ukucindezeleka okusalayo welding. e-ding weld inkulu, insimbi ye-weld ivame ukuba sesimweni sokucindezeleka ngezindlela ezintathu, okwandisa amathuba okuqhekeka.

Ngaphezu kwalokho, ngokwenqubo yokushisela i-arc engaphansi kwamanzi, i-weld ngayinye kufanele ibe lapho kuqalwa khona i-arc kanye nokucisha i-arc, kodwa umthungo ngamunye oqondile wepayipi oshiselwe kumthungo we-annular oshiselwe, awukwazi ukufeza lesi simo, ngaleyo ndlela kungase kube nokukhubazeka okwengeziwe kokushisela ku-arc. ukucisha.
