Isingeniso kanye Nokuqhathaniswa Kwezimbozo Zepayipi Zensimbi Evamile, okuhlanganisa i-Black Oil, i-3PE, i-FPE, kanye ne-ECET – ROYAL GROUP

1. Ukugqoka Amafutha Amnyama: Ukukhetha Okuphumelelayo Kokuvimbela Ukugqwala Okuvamile
Ukuze kuhlangatshezwane nezidingo zokuvimbela ukugqwala kwamapayipi ensimbi ajwayelekile, iRoyal Steel Group isebenzisa ubuchwepheshe bokumboza i-Black Oil ukuhlinzeka ngokuvikelwa okuyisisekelo kwamapayipi ensimbi asanda kukhiqizwa. Isetshenziswa ngendlela yokufutha ngoketshezi, ukumboza kufinyelela ubukhulu obulawulwa ngokunembile obungama-micron angu-5-8, okuvikela ngempumelelo emoyeni nasemswakeni, okunikeza ukuvimbela ukugqwala okuhle kakhulu. Ngenqubo yayo evuthiwe, ezinzile kanye nokusebenza kahle kwezindleko eziphakeme, ukumboza i-Black Oil sekuyindlela ejwayelekile yokuvikela imikhiqizo yamapayipi ensimbi ajwayelekile eQembu, okususa isidingo sezidingo ezengeziwe zamakhasimende. Isetshenziswa kabanzi kumaphrojekthi ahlukahlukene adinga ukuvimbela ukugqwala okubalulekile.

2. I-FBE Coating: Ukusetshenziswa Okunembile Kobuchwepheshe Be-Hot-Dissolved Epoxy

Ezinhlelweni ezidinga izinga eliphezulu lokuvikelwa kokugqwala, ubuchwepheshe bokumboza be-FBE (hot-dissolved epoxy) be-Royal Steel Group bubonisa izinzuzo eziphakeme. Le nqubo, esekelwe epayipini elingenalutho, iqala ngokususwa kokugqwala okuqinile kusetshenziswa i-SA2.5 (sandblasting) noma i-ST3 (ukususwa kwesilinganiso ngesandla) ukuqinisekisa ukuhlanzeka kobuso bepayipi kanye nokuqina kwayo kuhlangabezana nezindinganiso ezibekiwe. Ipayipi bese lishiswa ukuze linamathele ngokulinganayo impuphu ye-FBE ebusweni, kwakhiwe ungqimba olulodwa noma oluphindwe kabili lwe-FBE. Ungqimba lwe-FBE oluphindwe kabili luthuthukisa ukumelana nokugqwala, luzivumelanisa nezimo zokusebenza eziyinkimbinkimbi nezidingayo futhi lunikeze isithiyo esithembekile samapayipi kawoyela negesi.

3. Ukugqoka kwe-3PE: Ukuvikelwa Okuphelele Ngesakhiwo Esinezingqimba Ezintathu

Isixazululo sokumboza se-3PE seRoyal Steel Group sinikeza isivikelo esiphelele ngomklamo waso onezingqimba ezintathu. Ingqimba yokuqala iyimpuphu ye-epoxy resin elungiseka umbala, ebeka isisekelo esiqinile sokuvikela ukugqwala. Ingqimba yesibili iyingcina esobala, esebenza njengengqimba yokushintsha futhi ithuthukisa ukunamathelana phakathi kwezingqimba. Ingqimba yesithathu iyisimbozo esijikelezayo sezinto ze-polyethylene (PE), okuthuthukisa kakhulu umthelela wokumboza kanye nokumelana nokuguga. Lesi sixazululo sokumboza siyatholakala kokubili ezinguqulweni ezilwa nokuwela kanye nezingezona ezilwa nokuwela, ezenzelwe izidingo zamakhasimende, ezinikeza ukuzivumelanisa nezimo eziguquguqukayo ezimweni ezahlukahlukene zephrojekthi. Sisetshenziswa kabanzi kumapayipi okudlulisa amabanga amade kanye namapayipi obunjiniyela bomasipala.

4. Ukugqoka kwe-ECTE: Inketho Engabizi Kakhulu Yezicelo Ezingcwatshwe Nezicwiliswe Emanzini

Ngezicelo ezikhethekile ezifana nezicelo ezingcwatshwe kanye nezingcwatshwe emanzini, iRoyal Steel Group yethule isixazululo se-Epoxy Coal Tar Enamel Coating (ECTE). Lesi simbozo, esisekelwe ku-epoxy resin coal tar enamel, sigcina ukumelana okuhle kakhulu kokugqwala ngenkathi sinciphisa ngempumelelo izindleko zokukhiqiza, sinikeza amakhasimende inketho engabizi kakhulu. Nakuba izimbozo ze-ECTE zihilela ukungcola okuthile ngesikhathi sokukhiqiza, iQembu lithuthukise izinqubo zalo zokukhiqiza, lihlonyiswe ngemishini yokwelapha ebanzi yemvelo, kanye nokukhishwa kokungcola okulawulwa ngokuqinile, lifinyelela ibhalansi phakathi kokuhlangabezana nezidingo zephrojekthi kanye nokufeza imithwalo yemfanelo yezemvelo. Lokhu kwenze kwaba yisisombululo esithandwayo sokumboza samaphrojekthi afana namapayipi kawoyela angcwatshwe kanye namanethiwekhi amanzi angaphansi komhlaba.

5. Ukugqoka i-Fluorocarbon: Uchwepheshe Wokuvikela I-UV Yama-Pier Piles
Ngezinhlelo zokusebenza ezifana nama-pier piles, abonakala emisebeni enamandla ye-UV isikhathi eside, ubuchwepheshe bokumboza be-Fluorocarbon be-Royal Steel Group bubonisa izinzuzo eziyingqayizivele. Lo mbala ohlanganisa izingxenye ezimbili uqukethe izendlalelo ezintathu: owokuqala uyi-epoxy primer, i-zinc-rich primer, noma i-zinc-rich primer engenasisekelo, enikeza isisekelo esiqinile esingagqwali. Isendlalelo sesibili yi-epoxy micaceous iron intermediate coat evela kumkhiqizo odumile i-Sigmacover, okwandisa ukujiya kombala nokuvimbela ukungena. Isendlalelo sesithathu yi-fluorocarbon topcoat noma i-polyurethane topcoat. Ama-Fluorocarbon topcoat, ikakhulukazi lawo enziwe nge-PVDF (polyvinylidene fluoride), anikeza ukumelana okuhle kakhulu kwe-UV, isimo sezulu, kanye nokuguga, evikela ngempumelelo izisekelo zama-pile ekugugulekeni yimimoya yolwandle, i-salt spray, kanye nemisebe ye-UV. Iqembu liphinde libambisane nemikhiqizo yokumboza edumile njenge-Hempel, likhetha ama-primer alo kanye nama-midcoat ukuqinisekisa ikhwalithi iyonke yezingubo futhi linikeze isivikelo sesikhathi eside sengqalasizinda yasolwandle njengezindawo zokudoba kanye namachweba.

6. Ukugqoka Kwangaphakathi Kwamapayipi Amanzi: Isiqinisekiso Sokuhlanzeka se-IPN 8710-3
