Kufunika kwa Mapaipi Osemedwa Kawiri ndi Mapaipi Okhala ndi Polyurethane mu Kusemedwa kwa Mapaipi

Chitoliro cholumikizidwa kawiriamatanthauza chitoliro chomwe chalumikizidwa kawiri kuti chipange cholumikizira champhamvu komanso cholimba. Mtundu uwu wa chitoliro umagwiritsidwa ntchito kwambiri popanga mapaipi pomwe ubwino ndi mphamvu zolumikizira ndizofunikira kwambiri. Njira yolumikizira kawiri imaphatikizapo kugwiritsa ntchito njira zolumikizira kuti zigwirizane mapaipi awiri osiyana kuti zitsimikizire kulumikizana kolimba komanso kosasunthika. Izi sizimangowonjezera mphamvu ndi kulimba kwa chitoliro chonse, komanso zimachepetsa chiopsezo cha zolakwika zolumikizira ndi kutulutsa madzi.

Polyurethane chitoliro chokhala ndi mzereKomano, ndi chitoliro chokhala ndi polyurethane coating chomwe chimateteza kwambiri ku dzimbiri, kusweka, ndi kuukira kwa mankhwala. Chitolirocho chimayikidwa pamwamba pa chitoliro kuti chipange chotchinga pakati pa madzi omwe akunyamulidwa ndi pamwamba pa chitsulo cha chitolirocho. Mapaipi okhala ndi polyurethane ndi othandiza kwambiri pamapaipi omwe amagwiritsidwa ntchito kunyamula zinthu zowononga kapena kugwira ntchito m'malo ovuta. Mapaipi okhala ndi polyurethane samangowonjezera moyo wa mapaipi anu, komanso amachepetsa chiopsezo cha kutuluka kwa madzi ndi ndalama zokonzera.

Kuphatikiza apo, mphamvu yopangira yamapaipi achitsulo chozungulirandi yayikulu kwambiri kuposa mapaipi achitsulo chosasunthika. Pa chitoliro chosasunthika, njira yopangira imaphatikizapo kutulutsa billet yolimba yachitsulo kudzera mu ndodo yobowoka, zomwe zimapangitsa kuti njira yopangira ikhale yocheperako komanso yovuta kwambiri. Mosiyana ndi zimenezi, chitoliro cholumikizidwa ndi spiral chingapangidwe m'madigiri akuluakulu ndi kutalika, zomwe zimapangitsa kuti nthawi yopangira ikhale yochepa komanso kuti ntchito ikhale yogwira mtima kwambiri. Izi zimatsimikizira kuti mapaipi apamwamba amapezeka nthawi zonse m'nthawi yochepa, zomwe zimapangitsa kuti ikhale yankho lodalirika komanso losunga nthawi m'mafakitale osiyanasiyana.

Ubwino wina wodziwika bwino wa mapaipi olumikizidwa ndi spiral welded ndi kukana kwawo kupsinjika kwakunja ndi kupsinjika kwamakina. Ma weld amapereka kulimba kowonjezereka, zomwe zimathandiza mapaipi awa kupirira kupsinjika kwakukulu kuposa mapaipi osalumikizana. Katunduyu ndi wofunikira kwambiri pakugwiritsa ntchito mumakampani amafuta ndi gasi, komwe mapaipi amakumana ndi kupsinjika kwakukulu mkati ndi kunja. Pogwiritsa ntchito mapaipi olumikizidwa ndi spiral welded, makampani amatha kuwonetsetsa kuti zinthu zofunikazi zikuyendetsedwa bwino komanso mosamala.
