I-Royal Group, eyasungulwa ngo-2012, iyibhizinisi lobuchwepheshe obuphezulu eligxile ekuthuthukisweni, ekukhiqizweni nasekuthengisweni kwemikhiqizo yokwakha. Indlunkulu yethu itholakala eTianjin, idolobha eliphakathi nezwe kanye nendawo okwazalelwa kuyo i-"Three Meetings Haikou". Siphinde sibe namagatsha emadolobheni amakhulu ezweni lonke.
Ipayipi lensimbi yekhabhoni liyipayipi elivamile elenziwe kakhulu ngekhabhoni nensimbi, elisetshenziswa kabanzi embonini. Ngenxa yokuqina kwalo okuhle kakhulu, amandla, kanye nokumelana nokugqwala, livame ukusetshenziswa embonini kaphethiloli, amakhemikhali, kanye neyokwakha.
Kususelwa enkambisweni yokukhiqiza, ipayipi lensimbi yekhabhoni lihlukaniswe kakhulu njengepayipi elihlanganisiwe kanye nepayipi elingenamthungo. Ipayipi elihlanganisiwe lenziwa ngokuhlanganisa amapuleti ensimbi noma imichilo ndawonye, okunikeza ukusebenza kahle okuphezulu kokukhiqiza kanye nezindleko eziphansi. Livame ukusetshenziselwa ukuthuthwa koketshezi oluphansi ngomfutho ojwayelekile, njengokwakhiwa kwamanzi kanye namapayipi okukhipha amanzi. Ipayipi elingenamthungo lenziwa ngama-billet aqinile ngezinqubo ezifana nokubhoboza, ukugoqa okushisayo, kanye nokugoqa okubandayo. Udonga lwayo alunama-weld, okuholela ekuqineni nasekuvaleni okuthuthukisiwe, okuvumela ukuthi imelane nokucindezela okuphezulu kanye nezimo ezinzima. Amapayipi anomfutho ophezulu embonini ye-petrochemical, isibonelo, avame ukusetshenziselwa ipayipi elingenamthungo.
Ngokubukeka, amapayipi ensimbi yekhabhoni afika ngesimo esiyindilinga nesiyindilinga. Amapayipi ayindilinga acindezelwe ngokulinganayo, ahlinzeka ngokumelana okuncane kakhulu nokuthuthwa koketshezi. Amapayipi ayizikwele nayindilinga asetshenziswa kabanzi ekwakheni izakhiwo nasemishinini, enikeza izakhiwo zokusekela ezizinzile. Izinhlobo ezahlukene zamapayipi ensimbi yekhabhoni zidlala indima ebalulekile kumaphrojekthi ahlukahlukene obunjiniyela.
AMAPHAYIPHI ETHU ENTSIMBI YEKHABONI
Sinikeza uhla oluphelele lwemikhiqizo yensimbi yekhabhoni, kusukela kumapayipi kuya kumapuleti, amakhoyili kuya kumaphrofayili, ukuze kuhlangatshezwane nezidingo zamaphrojekthi akho ahlukahlukene.
Amapayipi ensimbi agqunywe nge-galvanized enziwe ngepayipi lensimbi elenziwe nge-zinc coating phezu komhlaba ngokusebenzisa i-hot-dip galvanizing noma i-electroplating. Njengoba ehlanganisa amandla aphezulu ensimbi nokumelana okuhle kakhulu nokugqwala kwe-zinc coating, asetshenziswa kabanzi ekwakheni, emandleni, kwezokuthutha, nasemishinini. Inzuzo yawo eyinhloko iwukuthi i-zinc coating ihlukanisa izinto eziyisisekelo ezivela ezintweni ezigqwalisayo ngokuvikela i-electrochemical, yandisa kakhulu impilo yesevisi yepayipi ngenkathi ilondoloza izakhiwo zensimbi ukuze ihlangabezane nezidingo zesakhiwo zokuthwala umthwalo zezimo ezahlukahlukene.
Ipayipi Lensimbi Eyindilinga Elakhiwe Nge-Galvanised
Izici Ezinqamulelayo: Isigaba esiyindilinga sinikeza ukumelana okuphansi koketshezi kanye nokumelana okufanayo kwengcindezi, okwenza kufanelekele ukuthuthwa koketshezi kanye nokusekelwa kwesakhiwo.
Izinto Ezivamile:
Izinto Eziyisisekelo: Insimbi yekhabhoni (njenge-Q235 ne-Q235B, amandla aphakathi nendawo futhi engabizi kakhulu), insimbi engenangxubevange ephansi (njenge-Q345B, amandla aphezulu, efanelekile ukusetshenziswa okunzima); izinto eziyisisekelo zensimbi engagqwali (njengensimbi engagqwali engu-304 ehlanganisiwe, enikeza kokubili ukumelana ne-asidi kanye ne-alkali kanye nobuhle) ziyatholakala kwizicelo ezikhethekile.
Izinto Zokusebenza Zesendlalelo Esihlanganisiwe: I-zinc emsulwa (i-hot-dip galvanizing enokuqukethwe kwe-zinc okungu-≥98%, ubukhulu bengqimba ye-zinc obungu-55-85μm, kanye nesikhathi sokuvikela ukugqwala seminyaka eyi-15-30), i-zinc alloy (i-zinc efakwe ngogesi enenani elincane le-aluminium/nickel, ubukhulu obungu-5-15μm, efanelekile ukuvikela ukugqwala kwangaphakathi okulula).
Osayizi Abavamile:
Ububanzi Bangaphandle: DN15 (1/2 intshi, 18mm) kuya ku-DN1200 (48 intshi, 1220mm), Ubukhulu Bodonga: 0.8mm (ipayipi lokuhlobisa elinodonga oluncane) kuya ku-12mm (ipayipi lesakhiwo elinodonga oluqinile).
Izindinganiso Ezisebenzayo: GB/T 3091 (yokuthutha ngamanzi negesi), GB/T 13793 (ipayipi lensimbi elihlanganisiwe ngogesi elinomthungo oqondile), ASTM A53 (yokufaka ipayipi lokucindezela).
Ishubhu Yesikwele Sensimbi Egayiwe
Izici Ezinqamulelayo: Isigaba esiyisikwele (ubude becala a×a), ukuqina okuqinile kokugoba, kanye nokuxhumeka okulula, okusetshenziswa kakhulu ezakhiweni zohlaka.
Izinto Ezivamile:
Isisekelo ngokuyinhloko yi-Q235B (ihlangabezana nezidingo zokuthwala imithwalo zezakhiwo eziningi), kanti i-Q345B kanye ne-Q355B (amandla aphezulu okukhiqiza, afanele izakhiwo ezimelana nokuzamazama komhlaba) ziyatholakala ukuze zisetshenziswe kakhulu.
Inqubo yokufaka i-galvanizing ngokuyinhloko iwukufaka i-hot-dip galvanizing (yokusetshenziswa ngaphandle), kuyilapho ukufaka i-electrogalvanizing kuvame ukusetshenziselwa ukuvikela izinto zangaphakathi.
Osayizi Abavamile:
Ubude Becala: 20×20mm (amashalofu amancane) kuya ku-600×600mm (izakhiwo zensimbi esindayo), ubukhulu bodonga: 1.5mm (ishubhu lefenisha eludongeni oluncane) kuya ku-20mm (ishubhu lokusekela ibhuloho).
Ubude: Amamitha ayi-6, ubude obungokwezifiso bamamitha angu-4-12 buyatholakala. Amaphrojekthi akhethekile adinga ukubhukha kusenesikhathi.
Ishubhu Eyisikwele Yensimbi Egayiwe
Izici Ezinqamulelayo: Ingxenye eyisikwele (ubude becala a×b, a≠b), kanti uhlangothi olude lugcizelela ukumelana nokugoba kanye nezinto ezigcina uhlangothi olufushane. Kufanelekela ukwakheka okuguquguqukayo.
Izinto Ezivamile:
Izinto eziyisisekelo zifana neshubhu lesikwele, kanti i-Q235B ingaphezu kuka-70%. Izinto ezisebenzisa i-alloy ephansi zisetshenziselwa izimo ezikhethekile zomthwalo.
Ubukhulu be-galvanizing bulungiswa ngokuya ngendawo yokusebenza. Isibonelo, i-hot-dip galvanizing ezindaweni ezisogwini idinga ≥85μm.
Osayizi Abavamile:
Ubude Ohlangothini: 20×40mm (ibhulakhethi elincane lemishini) kuya ku-400×800mm (ama-purlin ezitshalo zezimboni). Ubukhulu Bodonga: 2mm (umthwalo omncane) kuya ku-25mm (udonga olujiyile kakhulu, njengemishini yechweba).
Ukubekezelelana Okunezilinganiso:Iphutha Lobude Becala: ±0.5mm (ishubhu elinokunemba okuphezulu) kuya ku-±1.5mm (ishubhu ejwayelekile). Iphutha Lokujiya Kodonga: Ngaphakathi ±5%.
Sinikeza uhla oluphelele lwemikhiqizo yensimbi yekhabhoni, kusukela kumapayipi kuya kumapuleti, amakhoyili kuya kumaphrofayili, ukuze kuhlangatshezwane nezidingo zamaphrojekthi akho ahlukahlukene.
Ipayipi lensimbi engagqwali liyipayipi lensimbi elihlanganisa ukumelana nokugqwala, amandla aphezulu, inhlanzeko kanye nokuvikelwa kwemvelo. Lihlanganisa izinhlobo ezahlukene ezifana namapayipi angenamthungo namapayipi ahlanganisiwe. Lisetshenziswa kabanzi kwezobunjiniyela bokwakha, amakhemikhali kanye nemithi, ezokuthutha amandla kanye neminye imikhakha.
Ngokombono wokukhiqiza, amashubhu ayindilinga ensimbi engagqwali ahlukaniswe kakhuluamashubhu angenamthungofuthiamashubhu ahlanganisiwe. Amashubhu angenamthungoZikhiqizwa ngezinqubo ezifana nokubhoboza, ukugoqa okushisayo, kanye nokudweba okubandayo, okuholela ekutheni kungabikho imithungo ehlanganisiwe. Zinikeza amandla amakhulu kanye nokumelana nengcindezi, okwenza zifaneleke ukusetshenziswa njengokuthuthwa koketshezi olunomfutho ophezulu kanye nokuthwala umthwalo ngomshini.Amashubhu ahlanganisiweZenziwe ngamashidi ensimbi engagqwali, zigoqwe zibe yisimo, bese zishintshwa. Zisebenza kahle kakhulu ekukhiqizeni futhi zibiza kancane, okwenza zisetshenziswe kabanzi ekuthuthweni okunomfutho ophansi kanye nasezinhlelweni zokuhlobisa.
Ubukhulu obunqamulayo: Amashubhu ayisikwele asukela emaceleni kusukela kumashubhu amancane angu-10mm × 10mm kuya kumashubhu amakhulu angu-300mm × 300mm. Amashubhu angunxande avame ukuza ngobukhulu obufana no-20mm × 40mm, 30mm × 50mm, kanye no-50mm × 100mm. Osayizi abakhulu bangasetshenziswa ukusekela izakhiwo ezakhiweni ezinkulu. Ububanzi Bokujiya Kodonga: Amashubhu agqinsiwe (ubukhulu obungu-0.4mm-1.5mm) asetshenziswa kakhulu ezinhlelweni zokuhlobisa, anokucutshungulwa okulula nokulula. Amashubhu agqinsiwe (ubukhulu obungu-2mm nangaphezulu, kanye namashubhu athile ezimboni afinyelela ku-10mm nangaphezulu) afanelekela izinhlelo zokusebenza zokuthwala umthwalo wezimboni kanye nezokuthutha umfutho ophezulu, anikeza amandla amakhulu kanye nomthamo wokuthwala umfutho.
Ngokuphathelene nokukhethwa kwezinto, amashubhu ayindilinga ensimbi engagqwali enziwa kakhulu ngamamaki ensimbi engagqwali ajwayelekile. Isibonelo,304ivame ukusetshenziselwa amapayipi okucubungula ukudla, ukwakha izikhonkwane, kanye nezitsha zasekhaya.316Amashubhu ayindilinga ensimbi engagqwali avame ukusetshenziswa ekwakhiweni kogu, emapayipini amakhemikhali, kanye nasezintweni zokufaka imikhumbi.
Amashubhu ayindilinga ensimbi engagqwali angabizi, njenge201futhi430, zisetshenziswa kakhulu ezindongeni zokuhlobisa kanye nasezingxenyeni zesakhiwo ezinomthwalo omncane, lapho izidingo zokumelana nokugqwala ziphansi khona.
