Xa kuhlolwa imibhobho yentsimbi ukuze kujongwe igesi enoxinzelelo oluphantsi, unikezelo lwamanzi, okanye iinethiwekhi zokutshiza umlilo,I-EN 10255umgangatho ubhekisa kwihlabathi liphela phantse kuyo yonke imibuzo yobugcisa. Kwiingcali zokuthenga, kuyinto eqhelekileyo ukuthelekisa iikowuteshini ezisekelwe ikakhulu kwixabiso letoni nganye. Nangona kunjalo, ekwakheni nasekufakeni izinto, ixabiso lokuqala eliphantsi ngokungalindelekanga linokukhokelela kwiindleko ezinkulu ezifihlakeleyo.
Ukuba imibhobho ethunyelwa kwindawo yeprojekthi ibangela iingxaki ezifana nokuguguleka kwezixhobo ngaphambi kwexesha ngexesha lokufakwa kwemisonto, ukuvuza okuncinci kwamalungu, okanye ukugqwala kwangoko kwimisonto yoqhagamshelo, ukonga kweendleko zokuqala kukhawuleza kuncitshiswe kukulibaziseka kwabasebenzi kunye neendleko zokuphinda usebenze. Njengeqela elinamava elenza izinto elisingatha yonke inkqubo ukusuka ekucutshungulweni kwentsimbi eluhlaza ukuya kuvavanyo lokugqibela, sikholelwa ukuba ukuqonda iinkcukacha ezimbalwa ezibalulekileyo zemveliso kunokunceda ukuqinisekisa ukuba iprojekthi yakho ihlala ikhuselekile ngaphakathi kohlahlo-lwabiwo mali.
Kutheni Ukucocwa Okuthambileyo Kufuna Ulawulo Oluqinileyo Lomxholo Wekhabhoni
Isihloko esisemthethweni seenkcukacha ze-EN 10255 sigxininisa ukuba ezi tyhubhu zenzelwe ngokukodwa"Ukuwelda kunye nokuluka imisonto."Nangona le ngcaciso icacileyo, abathengi abaninzi baxela amava adimazayo ngexesha lokufakelwa kwendawo, njengokungcangcazela okukhulu koomatshini bokufaka imisonto abazenzekelayo, iiprofayili zemisonto ezirhabaxa okanye ezikrazukileyo, kunye nokuqhekeka rhoqo kwee-cutting dies ezibizayo.
Isizathu esisisiseko sidla ngokubuyela umva kubulukhuni obugqithisileyo bezinto kunye nokwakheka kweekhemikhali ezingazinzanga.
Ukunciphisa iindleko zemveliso, abanye abavelisi banokusebenzisa i-genericiikhoyili zentsimbiezineempawu zeekhemikhali ezingangqinelaniyo kakhulu.Iityhubhu zebanga le-S195T, ukwakheka kweekhemikhali kufuneka kulawulwe kakuhle ukususela ekuqaleniImpahla engekasilwainqanaba:
Ikhabhoni (C):Igcinwe phantsi ngqo0.20%
IManganese (Mn):Ilawulwa phantsi1.40%
I-Phosphorus (P) kunye ne-Sulphur (S):Imida ephezulu ebekwe kwi0.035% / 0.030%
Ngokugcina umxholo wekhabhoni uqinilengaphantsi kwe-0.20%umngcele, intsimbi igcina ukuqina kwayo okufanelekileyo. Xa izixhobo zokusika ezikwindawo zidibanisa umbhobho, oomatshini bezinto zokwakha basebenza kakuhle nangokulinganayo. Le ndlela ikhusela izixhobo zakho zokufaka imisonto ekonakalisweni kwangaphambili kwaye iqinisekisa imisonto ecocekileyo, enzulu edibana ngokugqibeleleyo nemixokelelwane eqhelekileyo ukwenza ijoyinti ethembekileyo ngokupheleleyo, engenako ukuvuza.
Itheyibhile yeMida ye-OD engapheliyo
Xa ukhangela iinkcukacha ze-EN 10255 kwi-intanethi, izishwankathelo ezininzi ezikhoyo zibonisa umbono olula obonisa ixabiso elinye lobubanzi bangaphandle—njenge-48.8 mm yombhobho we-DN40. Kunjineli weprojekthi okanye umphathi womgangatho, ukuthembela kuphela kwinani elinye akwanelanga.
I-EN 10255 ayisebenzi ngokunyamezelana okusekelwe kwipesenti okungacacanga okufana “±1%"Ngenxa yokuba ezi tyhubhu kufuneka zihlangane kakuhle nezifakelo ezisemgangathweni okanye ezinemiqolo, umgangatho uchazauluhlu olupheleleyo oluphezulu noluncinci lwemilimithakuyo yonke isayizi.
Ukuba ububanzi bombhobho budlula umda ophezulu nge-0.1 mm, idayethi yokuluka isenokungadibani ngokuchanekileyo. Ngokwahlukileyo koko, ukuba ububanzi buncinci kakhulu, ubunzulu bomsonto obuvelayo abuyi kuba banele, nto leyo edla ngokubangela ukungaphumeleli ngexesha lovavanyo lwe-hydrostatic. Apha ngezantsi kukho imida echanekileyo egcinwe ngexesha lokulinganisa i-workshop mill yethu:
| Ubungakanani (i-DN) | Ubungakanani boMsonto (Inch) | Uluhlu lwe-OD oluKhanyayo (mm) | Uluhlu oluPhakathi/olunzima lwe-OD (mm) | Udonga oluKhanyayo (mm) | Udonga oluPhakathi (mm) | Udonga Olunzima (mm) | Ubunzima obuPhakathi (kg/m) |

(Qaphela: Phantsi kwezikhokelo ezisemthethweni ze-EN 10255, ubukhulu obukhulu obufana ne-5″ kunye ne-6″ abubandakanyi ukhetho lwe-Light series, olumelwa yi-“—” kwitshathi.)
Iprotokholi yoMgangatho: Ukuqinisekisa uQinisekiso oluchanekileyo lokutyeba
Ezinye iincwadi zokwazisa zibonisa ukuba ukuhlolwa kobukhulu bodonga kwenziwa rhoqo embindini wetyhubhu egqityiweyo ngexesha lokwenziwa kwesantya esiphezulu. Ngokwembono esebenzayo, ukwenza uvavanyo lwe-micrometer ephakathi kwetyhubhu kuyo yonke imveliso ekhawulezayo akunakwenzeka ngokwesakhiwo. Inkqubo yethu yokuqinisekisa umgangatho igxile kwindlela ecacileyo, esebenzayo, nechanekileyo kakhulu.
Xa isarha ebhabhayo isika umbhobho wentsimbi ohambayo ukuya kubude, amandla e-blade ngokungenakuphepheka adala ii-burrs ezincinci zoomatshini kunye nokuguquguquka komphetho kwindawo ethile ebusweni obusikiweyo. Ukubeka i-micrometer eqhelekileyo ngqo phezu komgca wangaphandle kunokuphazamisa ngokungekho mthethweni umlinganiselo, ngamanye amaxesha kugqume iprofayili yodonga olungaphantsi kobukhulu ngokubonisa ukufundwa okungekho ngqiqweni, okunyuswe umoya.
Ukuthintela le ngxaki, iqela lethu elisemgangathweni liqeqeshwe ukushenxisa i-micrometer ukusuka kumphetho osikiweyo ukuze idlule ngokupheleleyo kwiindawo ezijikelezileyo kunye nendawo yokuguqulwa. Olu kubekwa luthile lunika ukufundwa okuchanekileyo ukuqinisekisa ukuba izinto zihlonipha ukunyamezelana kodonga okuphezulu okuvumelekileyo -12.5%. Ngaphezu koko, kuzo zonke ii-odolo zokufaka imisonto, siqinisekisa ukuba iziphelo zepayipi zigcinwa zicocekile kwaye zigudile ukuxhasa ukuphathwa okukhuselekileyo kwindawo kunye nokusebenza kwezixhobo okugudileyo.
Ukuncamathelisa nge-galvanizing: Ukuthintela ukuqhekeka kwe-zinc ngexesha lokuxovula imisonto
Kwinethiwekhi zokukhusela ulwelo nomlilo, ukuthintela ukugqwala kwangaphakathi nangaphandle kubalulekile. I-hot-dip galvanizing inika ukhuseleko olugqwesileyo, kodwa ijongene novavanyo oluthe ngqo loomatshini ngexesha lokufakelwa: xa amaqela esiza esika imisonto, ii-lathe blades zicheba ngokwasemzimbeni inxalenye yentsimbi edibeneyo. Ukuba i-zinc coating ayinayo i-adhesion efanelekileyo, uxinzelelo loomatshini lunokubangela ukuba umaleko we-galvanizing ojikelezileyo uxobuke okanye uqhekeke njengepeyinti eyomileyo, nto leyo eshiya intsimbi engaphantsi isengozini yokugqwala kwasekuqaleni.
Ukuze sijongane nalo mceli mngeni,ukuntywila okushushuInkqubo ijolise kwiiparameter ezimiselwe yiEN 10240iinkcukacha:Ngaphakathi kweZinc≥55μm(ngokugxininisa kumphezulu wangaphakathi ogudileyo ongenamaqhuqhuva e-zinc arhabaxa) kunyeNgaphandle kweZinc≥63μm.Sijonga ubude bokuhlamba nge-asidi kunye nobushushu bembiza ye-zinc ngokuchanekileyo okuphezulu. Olu lungelelwaniso luvumela i-zinc enyibilikisiweyo kunye nesiseko sentsimbi ukuba zihlangane ngokufanelekileyo, zenze umaleko ozinzileyo we-iron-zinc alloy. Xa izixhobo zokufaka imisonto zisikwa kumbhobho, umaleko we-zinc uhlala unamathele ngokuqinileyo kwintsimbi ngaphandle kokuxobuka. Nokuba ingcambu yemigca yemisonto esandula ukunqunyulwa apho intsimbi engenanto ivezwa khona, umaleko we-zinc ojikelezileyo ubonelela ngokhuseleko lwe-anodic oluzincamayo, olunceda ekunciphiseni ukugqwala ixesha elide.
Amagumbi okuvavanya ityuwa avavanya iisampulu zokugquma nge-hot-dip galvanized.
