Amapayipi anezingubo zokulwa nokugqwala
Imikhiqizo Isingeniso
Amazinga: Amazinga amapayipi ahlanganiswe nokugqwala asethwa izinhlangano ezifana ne-American Society for Testing and Materials (ASTM), i-International Organization for Standardization (ISO) kanye ne-National Society of Corrosion Engineers (NACE). Lawa mazinga acacisa izidingo zezinto zokumboza, izindlela zokufaka isicelo, izinqubo zokuhlola kanye namazinga okusebenza.
Izigaba ezisuselwe ekwelapheni okungaphezulu: Amapayipi anezingubo zokulwa nokugqwala angahlukaniswa ngokusekelwe ohlotsheni lwezingubo ezisetshenzisiwe. Izigaba ezijwayelekile zifaka:I-Fused Bonded Epoxy (FBE) Enamathela I-Polyethylene (PE) noma i-polypropylene (PP) enamathela Itiyela noma i-asphalt enamathela Upende ocebile weZinc I-Polyurethane enamathela I-Polyurethane enamathela Koqweqwe lwawo lwamalahle.
Izicelo: Amapayipi anembotshana evimbela ukugqwala asetshenziswa kakhulu ezimbonini ezahlukahlukene, ezihlanganisa: Uwoyela Negesi: Amapayipi asetshenziselwa ukuthutha uwoyela ongahluziwe, igesi yemvelo kanye nemikhiqizo kaphethiloli Amanzi kanye namanzi angcolile: amanzi angaphansi komhlaba kanye nendle Ikhemikhali kanye ne-petrochemical: ukuthutha amakhemikhali abolayo nama-acids Olwandle kanye nasogwini: kumapayipi angaphansi kolwandle kanye nezakhiwo zasogwini Ingqalasizinda: Ezosetshenziswa emabhulohweni, ezikhumulweni zemikhumbi nezinye izakhiwo ezichayeke ngaphansi kwezimo ezinzima zemvelo Lawa mapayipi abalulekile ekugcineni ubuqotho nempilo ende yengqalasizinda ebalulekile kanye nezinhlelo zezimboni, ikakhulukazi ezindaweni ezinokhahlo noma ezigqwalile. Uma ucacisa noma ukhetha ipayipi eline-anti-corrosion coating, kubalulekile ukubhekisela kumazinga afanelekile futhi uthintane nochwepheshe bemboni ukuqinisekisa ukuthi ukugqoka okukhethiwe kuhlangabezana nezidingo ezithile zesicelo esihlosiwe.
