Ipayipi elimnyama liyipayipi lensimbi elingenalutho ngaphandle kwezingubo zokuzivikela.Ipayipi elimnyama lisetshenziselwa izinhlelo zokusebenza ezihlukahlukene ekhaya.Kuvame kakhulu ukubona ipayipi elimnyama lisetshenziselwa ulayini wakho wegesi yemvelo kanye nemigqa yesistimu yokufafaza.Njengoba ipayipi elimnyama lingenayo into evikelayo, lingagqwala kalula ezindaweni ezimanzi noma ezinomswakama.Ukuze umise ipayipi ekugqwaleni noma ukugqwala ngaphandle, kufanele unikeze ungqimba lokuvikela ngaphandle kwepayipi.Indlela elula ukuyipenda.

YEBO.Sinokubambisana okuqinile ne-SINOSURE

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

Siphinde sibe nesikwele esingenalutho sepayipi yensimbi, ngokwezinga elijwayelekile: ASTM A500, EN10219, JIS G3466, GB/T6728 ebandayo eyakhiwe isikwele kanye nepayipi lensimbi elingunxande.

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

Amapayipi ensimbi ahlukene ahlukaniswe amapayipi ensimbi acwiliswayo abandayo kanye namapayipi ensimbi anamadiphu ashisayo.Amapayipi anamakhavani ngokuvamile asetshenziselwa amanzi, igesi, uwoyela kanye namanye amapayipi ajwayelekile anamandla aphezulu.Zibuye zisetshenziswe embonini kaphalafini, ikakhulukazi amapayipi enkundla kawoyela ezindaweni zikawoyela ezingasogwini, ama-cooler, amapayipi okushintshanisa isitimu samalahle kanye nezinqwaba zamapayipi ebhuloho, amapayipi asekela imayini, njll.

Kuthiwa ipayipi lensimbi lisetshenziselwa igesi kanye nokufudumeza.Njengepayipi lamanzi, inani elincane lokugqwala lizotholakala ngemva kweminyaka embalwa.Ayingcolisi nje kuphela izinto zokuhlanzeka, kodwa futhi amagciwane akhula odongeni lwangaphakathi lwepayipi.Ukugqwala kubangela okuqukethwe kwensimbi ephezulu emanzini futhi kubeke engozini impilo yomuntu.
I-hot dip galvanizing iwukucwilisa ipayipi lensimbi ku-asidi ukuze liwashwe, bese ulungisa isixazululo esinamanzi nge-ammonium chloride ewuketshezi olunamanzi noma i-zinc chloride ne-zinc chloride, bese uyithela emgodini.I-hot dip galvanized coating iyunifomu, inokunamathela okuqinile nempilo ende yesevisi.I-matrix yepayipi lensimbi elinothayela elishisayo idiphu iyisisombululo esiyinkimbinkimbi somzimba nesincibilikisiwe se-electroplating, ngakho ukusabela kwamakhemikhali kwakha isakhiwo esihlangene kanye nokumelana nokugqwala.Ungqimba lwe-alloy luhlanganiswe nongqimba oluhlanzekile lwezinc kanye nesisekelo sepayipi lensimbi, ngakho linokumelana okuqinile nokugqwala.
Ipayipi elibandayo elinothayela linezinsimbi zikagesi, futhi kunomehluko omkhulu phakathi kokumelana nokugqwala kanye nepayipi elinothayela elishisayo.Ukuze kuqinisekiswe ikhwalithi, abakhiqizi abaningi abasemthethweni bokuphatha ama-galvanizing abayisebenzisi i-electro galvanizing (i-cold plating).Lawo mabhizinisi amancane angahlelekile azosebenzisa i-electro galvanizing ngoba intengo ishibhile.Isendlalelo esinothayela sepayipi lensimbi elibandayo elidiphu liwukunamathela.Isendlalelo se-zinc sipakishwe ngokuzimela nge-matrix yepayipi yensimbi.Ungqimba lwe-zinc luncane, oluvele luxhunywe epayipini lensimbi futhi kulula ukuwa.Ngakho-ke, ukumelana nokugqwala kwayo kubi.Ngakho-ke, kwamanye amapayipi agqitshwe ngokuqondile, amapayipi ensimbi angamathayela akhiqizwa abakhiqizi abavamile asasetshenziswa.

Indlela yokususa ipayipi lensimbi eligqwalile?
Okokuqala, sebenzisa i-solvent ngaphandle kwensimbi ukuze ususe izinto eziphilayo.Ukugqwala kungase futhi zisuswe pickling ngemva ukuxubha ukuvimbela nokugqwala, ukuhlanza noma insimbi, nokugqwala, welding slag, njll Galvanizing ihlukaniswe thermoelectric enamathela kanye enamathela abandayo.I-Thermoelectric coating akulula ukugqwala futhi ukugqwala okubandayo kulula ukugqwala.

Ipayipi lamanje lamanzi omlilo manje ngokuyisisekelo lisebenzisa ipayipi likathayela, futhi ungqimba lwangaphandle lwepayipi likathayela lufakwa ongqimbeni lukapende.Kuyabonakala ukuthi ipayipi lomlilo lifakwe uthayela.Esakhiweni sensimbi, ubunjiniyela be-welding bubambe iqhaza.Ngakho-ke, ukusetshenziswa njalo kwepayipi lensimbi elinamandla kungavimbela ukuvela kwezimo zokugqwala isikhathi eside.

1. OD 219mm nangaphansi Kumaxhaka angamahexagonal alungele ulwandle apakishwe ngemicu yensimbi, Ngezihlilingi ezimbili zenayiloni zenqwaba ngayinye

2. ngaphezu kwe-OD 219mm ngobuningi noma ngokombono wangokwezifiso

3. amathani/isitsha esingu-25 kanye namathani ama-5/usayizi we-oda lokuhlola;

4. Ku-container engu-20" ubude obukhulu bungama-5.8m;

5. Esiqukathi esingu-40" ubukhulu obukhulu bungu-11.8m.

Ingxube esekwe ku-iron ithathwa njengensimbi ye-alloy lapho i-manganese inkulu kuno-1.65%, i-silicon ingaphezu kuka-0.5%, ithusi ngaphezu kuka-0.6%, noma amanye amanani amancane wezakhi ze-alloying ezifana ne-chromium, i-nickel, i-molybdenum, noma i-tungsten ikhona.Izinhlobonhlobo ezinkulu zezakhiwo ezihlukile zingadalelwa insimbi ngokufaka lezi zakhi endaweni yokupheka.

Inqubo yokuqhubeka nokucwengwa kwensimbi engagqwali ngokunciphisa okuqukethwe kwekhabhoni

Inani lekhabhoni ensimbini engagqwali kufanele libe ngaphansi kunalelo eliku-carbon steel noma insimbi ye-alloy ephansi (okungukuthi, insimbi enokuqukethwe kwe-alloying ngaphansi kuka-5%).Nakuba ama-arc furnaces kagesi (EAF) kuyindlela evamile yokuncibilika nokucwengisisa insimbi engagqwali, i-AOD iyisengezo esinomnotho, njengoba isikhathi sokusebenza sisifushane futhi amazinga okushisa ephansi kunase-EAF yokwenza insimbi.Ngaphezu kwalokho, ukusebenzisa i-AOD yokucwenga insimbi engagqwali kukhulisa ukutholakala kwe-EAF ngezinjongo zokuncibilika.

Insimbi encibilikisiwe, engacolisisiwe idluliswa isuka ku-EAF iye emkhunjini ohlukile.Ingxube ye-argon ne-oxygen ishaywa kusukela phansi komkhumbi ngensimbi encibilikile.Ama-agent okuhlanza afakwa emkhunjini kanye nalawa magesi ukuze aqede ukungcola, kuyilapho umoya-mpilo uhlanganisa ne-carbon ensimbi engahlanjululwanga ukunciphisa izinga le-carbon.Ukuba khona kwe-argon kuthuthukisa ukuhlangana kwekhabhoni ye-oxygen futhi ngaleyo ndlela kusiza ukususwa kwe-carbon.

Ukugqwala kwensimbi yesakhiwo kuyinqubo ye-electrochemical edinga ukuba khona ngesikhathi esisodwa komswakama nomoya-mpilo.Uma kungekho kokubili, ukugqwala akwenzeki.Empeleni, insimbi esensimbi ifakwa i-oxidised ukuze ikhiqize ukugqwala, okuthatha cishe izikhathi eziyisi-6 kumthamo wento yokuqala edliwe kule nqubo.Inqubo yokugqwala evamile iboniswa lapha.Kanye nokugqwala okuvamile, kunezinhlobo ezihlukahlukene zokugqwala kwendawo ezingase zenzeke;ukugqwala kwe-bimetallic, ukugqwala kwe-pitting kanye nokugqwala kwe-crevice.Kodwa-ke, lokhu kuvame ukungabaluleki emisebenzini yensimbi yesakhiwo.Izinga lapho inqubo yokugqwala iqhubeka khona lincike ezintweni eziningi ezihlobene 'nesimo sezulu esincanyana' esizungeze isakhiwo, ikakhulukazi isikhathi sokumanzi kanye nezinga lokungcoliswa komoya.Ngenxa yokuhluka kwezindawo zomkhathi, idatha yezinga lokugqwala ayikwazi ukwenziwa jikelele.Kodwa-ke, izindawo zingahlukaniswa kabanzi, futhi amazinga okugqwala kwensimbi ahambisanayo anikeza inkomba ewusizo yamazinga okugqwala okungenzeka.Ulwazi olwengeziwe lungatholakala ku-BS EN ISO 12944-2 naku-BS EN ISO 9223

PendiweI-SHS (izingxenye ezingenalutho eziyisikwele)kanye ne-RHS (izingxenye eziyizigodi eziwunxande) ziyizingxenye zensimbi eziqinile ezakheke ngokubanda ezingenalutho ezipendwe kuqala ukuze zivikeleke ngesikhathi sokugcinwa nokuphathwa.

Umphumela wesithombe we-Hot dip galvanized square steel pipe
Esikhathini eside, ukuchayeka okuqhubekayo, izinga lokushisa eliphezulu elinconyiwe lensimbi efakwe insimbi eshisayo yi-200 °C (392 °F), ngokusho kwe-American Galvanizers Association.Ukusetshenziswa kwensimbi emazingeni okushisa angaphezu kwalokhu kuzoholela ekuxebukeni kwe-zinc ongqimbeni oluphakathi kwensimbi.
