Ipayipi elimnyama liyipayipi lensimbi elivamile elingenazo izembozo zokuvikela. Ipayipi elimnyama lisetshenziselwa izinhlelo ezahlukene ekhaya. Kuvamile kakhulu ukubona ipayipi elimnyama lisetshenziswa emigqeni yakho yegesi yemvelo kanye nemigqa yesistimu yokufafaza. Njengoba ipayipi elimnyama lingenazo izembozo zokuvikela, lingase ligqwale kalula ezindaweni ezimanzi noma ezinomswakama. Ukuze uvimbele ipayipi ekugqwaleni noma ekuboleni ngaphandle, kufanele unikeze ungqimba lokuvikela ngaphandle kwepayipi. Indlela elula ukuyipenda.

YEBO. Sinobambiswano oluqinile ne-SINOSURE

I-RHS imele i-Rectangular Hollow Section, okungukuthi ipayipi lensimbi elingunxande.

Siphinde sibe nepayipi lensimbi eliyisikwele elinengxenye engenalutho, ngokwezinga elijwayelekile: ASTM A500, EN10219, JIS G3466, GB/T6728 ipayipi lensimbi eliyisikwele neliyindilinga elibandayo.

Ipayipi lensimbi le-ERW, ipayipi lensimbi le-SSAW, ipayipi lensimbi le-LSAW, ipayipi lensimbi elihlanganisiwe, ipayipi lensimbi engagqwali, ipayipi le-casing and tube, i-elbow, i-reducer, i-tee, i-cap, i-coupling, i-flange, i-weldolet, ipayipi lensimbi elingenamthungo

TT, L/C (Nge-oda elikhulu, izinsuku ezingama-30-90 zingamukeleka).

Amapayipi ensimbi ahlanganisiwe ahlukaniswe ngamapayipi ensimbi ahlanganisiwe abandayo kanye namapayipi ensimbi ahlanganisiwe ashisayo. Amapayipi ahlanganisiwe avame ukusetshenziselwa amanzi, igesi, uwoyela kanye neminye ipayipi evamile yoketshezi olunomfutho ophezulu. Asetshenziswa futhi embonini kaphethroli, ikakhulukazi amapayipi ensimu kawoyela ezindaweni zikawoyela ezingasogwini, ezindaweni zokupholisa, amapayipi okushintshana ngomusi wamalahle kanye nezinqwaba zamapayipi ebhuloho, amapayipi okusekela imayini, njll.

Kuthiwa ipayipi lensimbi elenziwe nge-galvanized lisetshenziselwa igesi nokushisa. Njengepayipi lamanzi, inani elincane lokugqwala lizotholakala ngemva kweminyaka embalwa. Aligcini nje ngokungcolisa izinto zangasese, kodwa futhi nama-bacteria akhula odongeni lwangaphakathi lwepayipi. Ukugqwala kubangela okuqukethwe okuphezulu kwensimbi emanzini futhi kubeka impilo yabantu engozini.
Ukugaya i-hot dip kuwukucwilisa ipayipi lensimbi ku-asidi yokugeza, bese ulungisa isixazululo samanzi ngesisombululo samanzi se-ammonium chloride noma i-zinc chloride kanye ne-zinc chloride, bese uyithela emseleni. I-hot dip galvanized coating iyafana, inokunamathela okuqinile kanye nokuphila isikhathi eside. I-matrix yepayipi lensimbi eligayiwe eligayiwe eligayiwe eliyi-electroplating eyinkimbinkimbi, ngakho-ke ukusabela kwamakhemikhali kwakha ukwakheka okuhlangene kanye nokumelana nokugqwala. Ingqimba ye-alloy ihlanganiswe nengqimba ye-zinc emsulwa kanye nesisekelo sepayipi lensimbi, ngakho-ke inokumelana okuqinile kokugqwala.
Ipayipi elibandayo elihlanganisiwe liyi-electro galvanized, futhi kunomehluko omkhulu phakathi kokumelana nokugqwala kanye nepayipi elishisayo elihlanganisiwe. Ukuze kuqinisekiswe ikhwalithi, abakhiqizi abaningi abasemthethweni bokuphatha i-galvanizing abafaki i-electro galvanizing (i-cold plating). Lawo mabhizinisi amancane angakahleleki azosebenzisa i-electro galvanizing ngoba intengo ishibhile. Ingqimba elihlanganisiwe lepayipi lensimbi elihlanganisiwe elihlanganisiwe liyi-coating. Ingqimba le-zinc lihlanganiswe ngokuzimela nge-matrix yepayipi lensimbi. Ingqimba le-zinc lincane, elixhunywe nje nepayipi lensimbi futhi kulula ukuliyeka. Ngakho-ke, ukumelana kwalo nokugqwala kubi. Ngakho-ke, kwamanye amapayipi angcwatshwe ngqo, amapayipi ensimbi ensimbi ahlanganisiwe akhiqizwa abakhiqizi abavamile asasetshenziswa.

Ungasusa kanjani ipayipi lensimbi eligobile?
Okokuqala, faka isinyibilikisi ngaphandle kwensimbi ukuze ususe izinto eziphilayo. Ukugqwala kungasuswa nangokufaka i-pickling ngemva kokuxubha ukuvimbela ukugqwala, ukuhlanza noma i-ayina, ukugqwala, i-welding slag, njll. I-Galvanizing ihlukaniswe nge-thermoelectric coating kanye ne-coating ebandayo. I-thermoelectric coating akulula ukuyigqwala kanti i-coating ebandayo kulula ukuyigqwala.

Ipayipi lamanzi omlilo lamanje manje lisebenzisa ipayipi elihlanganisiwe, kanti ungqimba lwangaphandle lwepayipi elihlanganisiwe lufakwa engqimbeni yopende. Kungabonakala ukuthi ipayipi lomlilo empeleni lihlanganisiwe. Esakhiweni sensimbi, ubunjiniyela bokushisela bunengxenye yalo. Ngakho-ke, ukusetshenziswa njalo kwepayipi lensimbi elihlanganisiwe kungavimbela ukugqwala isikhathi eside.

Ingxube esekelwe ensimbini ibhekwa njengensimbi ye-alloy lapho i-manganese ingaphezu kuka-1.65%, i-silicon ingaphezu kuka-0.5%, ithusi lingaphezu kuka-0.6%, noma ezinye izinto ezincane kakhulu ze-alloy ezifana ne-chromium, i-nickel, i-molybdenum, noma i-tungsten zikhona. Izinhlobo eziningi zezakhiwo ezihlukile zingadalwa ngensimbi ngokufaka lezi zinto endaweni yeresiphi.

Inqubo yokuqhubeka nokuthuthukisa insimbi engagqwali ngokunciphisa okuqukethwe yikhabhoni

Inani lekhabhoni ensimbini engagqwali kumele libe ngaphansi kwelensimbi yekhabhoni noma ensimbini ye-alloy ephansi (okungukuthi, insimbi enokuqukethwe kwe-alloying element ngaphansi kuka-5%). Ngenkathi ama-arc furniture kagesi (i-EAF) kuyindlela evamile yokuncibilikisa nokucwenga insimbi engagqwali, i-AOD iyisengezo esingabizi, njengoba isikhathi sokusebenza sifushane futhi amazinga okushisa aphansi kune-EAF steelmaking. Ngaphezu kwalokho, ukusebenzisa i-AOD ekucwengisiseni insimbi engagqwali kwandisa ukutholakala kwe-EAF ngezinjongo zokuncibilikisa.

Insimbi encibilikisiwe, engacwengiwe idluliselwa kusuka ku-EAF iye esitsheni esihlukile. Ingxube ye-argon nomoya-mpilo iyapheshulwa kusukela phansi kwesitsha ngensimbi encibilikisiwe. Izinto zokuhlanza zengezwa esitsheni kanye nala magesi ukuze kususwe ukungcola, kuyilapho umoya-mpilo uhlangana nekhabhoni ensimbini engacwengiwe ukuze kuncishiswe izinga lekhabhoni. Ukuba khona kwe-argon kuthuthukisa ukusondelana kwekhabhoni nomoya-mpilo futhi ngaleyo ndlela kusiza ekususweni kwekhabhoni.

Ukugqwala kwensimbi yesakhiwo kuyinqubo ye-electrochemical edinga ukuba khona komswakama nomoya-mpilo ngasikhathi sinye. Uma kungekho noma yikuphi, ukugqwala akwenzeki. Empeleni, insimbi ensimbini iyashiswa ukuze ikhiqize ukugqwala, okuthatha cishe izikhathi ezi-6 zomthamo wezinto zokuqala ezisetshenziswe kule nqubo. Inqubo yokugqwala ejwayelekile iboniswe lapha. Ngaphezu kokugqwala okuvamile, kunezinhlobo ezahlukene zokugqwala kwendawo okungase kwenzeke; ukugqwala kwe-bimetallic, ukugqwala kwemigodi kanye nokugqwala kwe-crevice. Kodwa-ke, lokhu akuvamile ukuba yigugu emsebenzini wensimbi yesakhiwo. Izinga lapho inqubo yokugqwala iqhubeka khona lincike ezintweni eziningana ezihlobene 'nesimo sezulu esincane' esizungeze isakhiwo, ikakhulukazi isikhathi somswakama kanye nezinga lokungcola komoya. Ngenxa yokwehluka ezindaweni zomoya, idatha yesilinganiso sokugqwala ayikwazi ukuhlanganiswa. Kodwa-ke, izindawo zingahlukaniswa kabanzi, futhi amazinga okugqwala ensimbi alinganisiwe ahambisanayo anikeza inkomba ewusizo yamazinga okugqwala okungenzeka. Ulwazi olwengeziwe lungatholakala ku-BS EN ISO 12944-2 kanye ne-BS EN ISO 9223

KupendweI-SHS (izingxenye ezingenalutho eziyisikwele)kanye ne-RHS (izingxenye ezingenalutho ezingunxande) ziyizingxenye zensimbi ezingenalutho ezakhiwe ngokubandayo ezipendwe nge-primer ukuze zivikeleke ngesikhathi sokugcina nokuphatha.

Umphumela wesithombe sepayipi lensimbi eliyisikwele elishisayo eligayiwe
Uma ubhekene nokushisa okuqhubekayo isikhathi eside, izinga lokushisa eliphakeme elinconywayo lensimbi egayiwe eshisayo lingu-200 °C (392 °F), ngokusho kwe-American Galvanizers Association. Ukusetshenziswa kwensimbi egayiwe emazingeni okushisa angaphezu kwalokhu kuzoholela ekuqhekekeni kwe-zinc engqimbeni yensimbi ephakathi.
