I-Royal Group, eyasekwa ngo-2012, lishishini lobuchwepheshe obuphezulu eligxile kuphuhliso, imveliso kunye nokuthengiswa kweemveliso zokwakha. Ikomkhulu lethu likwiTianjin, isixeko esiphakathi sesizwe kunye nendawo yokuzalwa kwe-"Three Meetings Haikou". Sikwanamasebe kwizixeko ezikhulu kulo lonke ilizwe.
Umbhobho wentsimbi yekhabhoni yinto eqhelekileyo yombhobho eyenziwe ikakhulu yikhabhoni kunye nesinyithi, esetyenziswa kakhulu kushishino. Ngenxa yokuzinza kwayo okuhle, amandla, kunye nokumelana nokugqwala, isetyenziswa rhoqo kumashishini epetroleum, amakhemikhali, kunye nokwakha.
Ngokusekelwe kwinkqubo yemveliso, umbhobho wentsimbi yekhabhoni uhlelwe ngokuyintloko njengombhobho odibeneyo kunye nombhobho ongenamthungo. Umbhobho odibeneyo wenziwa ngokuhlanganisa iipleyiti zentsimbi okanye imicu kunye, okubonelela ngempumelelo ephezulu yemveliso kunye nexabiso eliphantsi. Isetyenziswa rhoqo ekuthuthweni kolwelo oluphantsi koxinzelelo, njengokwakha unikezelo lwamanzi kunye nemibhobho yokukhupha amanzi. Umbhobho ongenamthungo wenziwa ngeebhilethi eziqinileyo ngeenkqubo ezifana nokubhoboza, ukuqengqeleka okushushu, kunye nokuqengqeleka okubandayo. Udonga lwayo alunazo ii-welds, nto leyo ebangela ukuba luphuculwe amandla kunye nokutywinwa, okuvumela ukuba imelane noxinzelelo oluphezulu kunye neemeko ezinzima. Imibhobho enoxinzelelo oluphezulu kushishino lwe-petrochemical, umzekelo, idla ngokusetyenziselwa imibhobho engenamthungo.
Ngokwembonakalo, iipayipi zentsimbi yekhabhoni ziza ngendlela engqukuva neyingxande. Iipayipi ezingqukuva zixinene ngokulinganayo, zibonelela ngokumelana okuncinci nokuthuthwa kolwelo. Iipayipi ezisikwere nezingxande zisetyenziswa kakhulu kwizakhiwo zokwakha kunye nokuveliswa koomatshini, zibonelela ngezakhiwo ezixhasayo ezizinzileyo. Iindidi ezahlukeneyo zeepayipi zentsimbi yekhabhoni zidlala indima ebalulekileyo kwiiprojekthi ezahlukeneyo zobunjineli.
IMIBHAYI YETHU YENKONZO YEKHABONI
Sinikezela ngoluhlu olupheleleyo lweemveliso zentsimbi yekhabhoni, ukusuka kwiipayipi ukuya kwiipleyiti, iikhoyili ukuya kwiiprofayili, ukuhlangabezana neemfuno zeeprojekthi zakho ezahlukeneyo.
Iipayipi zentsimbi ezigqunyiweyo zenziwe ngombhobho wentsimbi yesinyithi one-zinc coating eyenziwe phezu komhlaba nge-hot-dip galvanizing okanye i-electroplating. Zidibanisa amandla aphezulu entsimbi kunye nokumelana okuhle kokugqwala kwe-zinc coating, zisetyenziswa kakhulu ekwakheni, kumandla, ekuthuthweni, nakwimveliso yoomatshini. Inzuzo yazo ephambili kukuba i-zinc coating yahlula izinto ezisisiseko kwi-corrosive media ngokukhusela i-electrochemical, yandisa kakhulu ubomi benkonzo yombhobho ngelixa igcina iipropati ze-mechanical zentsimbi ukuhlangabezana neemfuno zesakhiwo zokuthwala umthwalo kwiimeko ezahlukeneyo.
Umbhobho weNtsimbi eRound egalelweyo
Iimpawu ezinqamlezileyo: I-cross-section ejikelezayo inika ukumelana okuphantsi kolwelo kunye nokumelana okufanayo koxinzelelo, okwenza ukuba ifaneleke ukuthuthwa kolwelo kunye nenkxaso yesakhiwo.

Ityhubhu yesikwere sentsimbi egalelweyo
Iimpawu ezinqamlezileyo: Isikwere esinqamlezileyo (ubude becala a×a), ukuqina okuqinileyo kokujika, kunye noqhagamshelo olulula olucwangcisiweyo, olusetyenziswa rhoqo kwizakhiwo zesakhelo.
Izixhobo eziqhelekileyo:
Isiseko ngokuyintloko yi-Q235B (iyahlangabezana neemfuno zokuthwala imithwalo zezakhiwo ezininzi), kunye ne-Q345B kunye ne-Q355B (amandla aphezulu okuvelisa, afanelekileyo kwizakhiwo ezimelana nenyikima) ezifumanekayo kwizicelo eziphezulu.
Inkqubo yokwenza i-galvanizing isetyenziswa kakhulu xa kusenziwa i-hot-dip galvanizing (yokusetyenziswa ngaphandle), ngelixa i-electrogalvanizing isetyenziswa rhoqo xa kuhonjiswa ngaphakathi.
Ubungakanani obuqhelekileyo:
Ubude Becala: 20×20mm (iishelufu ezincinci) ukuya kwi-600×600mm (izakhiwo zentsimbi enzima), ubukhulu bodonga: 1.5mm (ityhubhu yefenitshala eludongeni olubhityileyo) ukuya kwi-20mm (ityhubhu yokuxhasa ibhulorho).
Ubude: Iimitha ezi-6, ubude obuqhelekileyo beemitha ezi-4-12 buyafumaneka. Iiprojekthi ezikhethekileyo zifuna ukubhukisha kwangaphambili.
Ityhubhu yoxande yentsimbi egayiweyo
Iimpawu ezinqamlezileyo: Inxalenye enqamlezileyo engunxande (ubude becala a×b, a≠b), icala elide ligxininisa ukuxhathisa ukugoba kunye nezinto zokugcina icala elifutshane. Ifanelekile kwiindlela eziguquguqukayo.
Izixhobo eziqhelekileyo:
Izinto ezisisiseko ziyafana netyhubhu yesikwere, apho i-Q235B ingaphezulu kwe-70%. Izinto ezisebenzisa i-alloy encinci zisetyenziselwa iimeko ezikhethekileyo zomthwalo.
Ubukhulu be-galvanizing bulungiswa ngokwemeko yokusebenza. Umzekelo, i-hot-dip galvanizing kwiindawo ezikunxweme ifuna i-≥85μm.
Ubungakanani obuqhelekileyo:
Ubude Becala: 20×40mm (isibiyeli sezixhobo esincinci) ukuya kwi-400×800mm (iipurlin zezityalo zoshishino). Ubukhulu Bodonga: 2mm (umthwalo omncinci) ukuya kwi-25mm (udonga olutyebileyo, olufana noomatshini bezibuko).
Ukunyamezelana Okunemilinganiselo:Impazamo yoBude becala: ±0.5mm (ityhubhu echanekileyo kakhulu) ukuya ku-±1.5mm (ityhubhu eqhelekileyo). Impazamo yoBungqingqwa boDonga: Ngaphakathi ±5%.
Sinikezela ngoluhlu olupheleleyo lweemveliso zentsimbi yekhabhoni, ukusuka kwiipayipi ukuya kwiipleyiti, iikhoyili ukuya kwiiprofayili, ukuhlangabezana neemfuno zeeprojekthi zakho ezahlukeneyo.
Umbhobho wentsimbi engagqwaliyo ngumbhobho wentsimbi odibanisa ukumelana nokugqwala, amandla aphezulu, ucoceko kunye nokukhuselwa kwendalo. Ugubungela iintlobo ezahlukeneyo ezifana nemibhobho engenamthungo kunye nemibhobho edibeneyo. Isetyenziswa kakhulu kubunjineli bokwakha, iikhemikhali kunye namayeza, ukuthuthwa kwamandla kunye neminye imimandla.
Ngokwembono yemveliso, iityhubhu ezijikelezileyo zentsimbi engagqwaliyo zahlulwe kakhulu zibeiityhubhu ezingenamthungokwayeiityhubhu ezidityanisiweyo. Iityhubhu ezingenamthungoZenziwa ngeenkqubo ezifana nokugqobhoza, ukuqengqeleka okushushu, kunye nokutsalwa okubandayo, nto leyo ebangela ukuba kungabikho mithungo idibeneyo. Zinika amandla amakhulu kunye nokumelana noxinzelelo, nto leyo ezenza zilungele ukusetyenziswa njengothutho lolwelo olunoxinzelelo oluphezulu kunye nokuthwala umthwalo ngoomatshini.Iityhubhu ezidityanisiweyozenziwe ngamashiti entsimbi engagqwaliyo, zigoqwe zibe yimo, zize emva koko zifakwe i-welded. Zisebenza kakuhle kakhulu kwimveliso kwaye zixabisa kancinci, nto leyo eyenza ukuba zisetyenziswe kakhulu ekuthuthweni okunoxinzelelo oluphantsi kunye nokusetyenziswa kokuhombisa.
Ubukhulu obunqamlezileyo: Iityhubhu zesikwere zinobude obuvela kwiityhubhu ezincinci ze-10mm × 10mm ukuya kwiityhubhu ezinkulu ze-300mm × 300mm. Iityhubhu ezizinxantathu zihlala ziza ngobukhulu obufana ne-20mm × 40mm, 30mm × 50mm, kunye ne-50mm × 100mm. Ubukhulu obukhulu bungasetyenziselwa ukuxhasa izakhiwo kwizakhiwo ezinkulu. Uluhlu loButyebi boDonga: Iityhubhu eziziindonga ezincinci (0.4mm-1.5mm ubukhulu) zisetyenziswa kakhulu kwizicelo zokuhombisa, zinobunzima obulula kwaye kulula ukuzilungisa. Iityhubhu eziziindonga ezinkulu (2mm ubukhulu nangaphezulu, kunye nezinye iityhubhu zemizi-mveliso ezifikelela kwi-10mm nangaphezulu) zifanelekile kwizicelo zokuthutha ezithwala umthwalo kwimizi-mveliso kunye nezoxinzelelo oluphezulu, zinika amandla amakhulu kunye nomthamo wokuthwala uxinzelelo.
Ngokuphathelele ukhetho lwezinto, iityhubhu ezijikelezileyo zentsimbi engagqwaliyo zenziwe kakhulu ngeendidi zentsimbi engagqwaliyo. Umzekelo,304isetyenziswa kakhulu ekulungiseni ukutya, ekwakheni ii-handrails, nakwizinto zasekhaya.316Iityhubhu ezijikelezileyo zentsimbi engagqwaliyo zihlala zisetyenziswa kulwakhiwo lwaselunxwemeni, kwiipayipi zamakhemikhali, nakwiindawo zokufakelwa iinqanawa.
Iityhubhu ezijikelezileyo zentsimbi engagqwaliyo, ezifana201kwaye430, zisetyenziswa kakhulu kwiindlela zokuhombisa kunye neendawo zokwakha ezinomthwalo omncinci, apho iimfuno zokumelana nokugqwala ziphantsi.
