Flange na FRP
Bayanin Samfurin
Flanges na FRP (Fiberglass Reinforced Plastic) sune masu haɗakar zobe da ake amfani da su don haɗa bututu, bawuloli, famfo, ko wasu kayan aiki don ƙirƙirar cikakken tsarin bututu. An yi su ne daga kayan haɗin da suka ƙunshi zare na gilashi a matsayin kayan ƙarfafawa da kuma resin roba a matsayin matrix. Ana ƙera su ta amfani da hanyoyin ƙira, shimfiɗa hannu, ko naɗewar filament.
Fasallolin Samfura
Godiya ga keɓantaccen abun da ke ciki, flanges na FRP suna ba da fa'idodi masu mahimmanci akan flanges na ƙarfe na gargajiya:
- Kyakkyawan Juriya ga Tsatsa: Mafi kyawun fasalin flanges na FRP shine ikonsu na tsayayya da tsatsa daga hanyoyin sinadarai daban-daban, gami da acid, alkalis, gishiri, da abubuwan narkewa na halitta. Wannan yana sa a yi amfani da su sosai a cikin muhallin da ake jigilar ruwa mai lalata, kamar a cikin sinadarai, man fetur, masana'antar ƙarfe, wutar lantarki, magunguna, da masana'antar abinci.
- Mai Sauƙi da Ƙarfi Mai Girma: Yawan FRP yawanci yana da kashi 1/4 zuwa 1/5 na ƙarfe, duk da haka ƙarfinsa za a iya kwatanta shi. Wannan yana sauƙaƙa jigilar su da shigarwa, kuma yana rage nauyin da ke kan tsarin bututun.
- Kyakkyawan Rufin Wutar Lantarki: FRP abu ne da ba ya da wutar lantarki, yana ba wa flanges na FRP kyawawan halayen rufin lantarki. Wannan yana da mahimmanci a takamaiman yanayi don hana tsatsa ta lantarki.
- Babban Sauƙin Zane: Ta hanyar daidaita tsarin resin da kuma shirya zaruruwan gilashi, ana iya yin flanges na FRP musamman don biyan takamaiman buƙatun zafin jiki, matsin lamba, da juriya ga tsatsa.
- Ƙarancin Kuɗin Kulawa: Flanges na FRP ba sa tsatsa ko ƙaruwa, wanda ke haifar da tsawon rai na sabis kuma yana rage farashin kulawa da maye gurbin sosai.
Nau'in Samfuri
Dangane da tsarin masana'anta da tsarin su, ana iya rarraba flanges na FRP zuwa nau'ikan da yawa:
- Flange Mai Kashi Ɗaya (Haɗaɗɗen): An samar da wannan nau'in a matsayin naúrar guda ɗaya tare da jikin bututun, yana ba da tsari mai tsauri wanda ya dace da aikace-aikacen ƙasa zuwa matsakaici.
- Flange mai laushi (Lap Joint Flange): Ya ƙunshi zoben flange mai sassauƙa, mai juyawa kyauta da kuma ƙarshen stub a kan bututun. Wannan ƙira tana sauƙaƙa shigarwa, musamman a cikin haɗin maki da yawa.
- Flange Mai Rufewa (Flank Flange/Ƙarfe na Ƙarshe): Ana amfani da shi don rufe ƙarshen bututu, yawanci don duba tsarin bututun ko don yin ajiyar hanyar sadarwa.
- Flange na Socket: Ana saka bututun a cikin ramin ciki na flange ɗin kuma a haɗa shi da kyau ta hanyar haɗa manne ko hanyoyin murɗawa, wanda ke tabbatar da kyakkyawan aikin rufewa.

Aikace-aikacen Samfura
Saboda ƙarfinsu na musamman na juriyar tsatsa da kuma ƙarfin nauyi, ana amfani da flanges na FRP sosai a cikin:
- Masana'antar Sinadarai: Don bututun mai da ke jigilar sinadarai masu lalata kamar acid, alkalis, da gishiri.
- Injiniyan Muhalli: A fannin sarrafa ruwan shara da kuma kayan aikin tsaftace iskar gas.
- Masana'antar Wutar Lantarki: Don sanyaya ruwa da tsarin cire sulfurization/denitrification a tashoshin wutar lantarki.
- Injiniyan Ruwa: A fannin tace ruwan teku da kuma tsarin bututun ruwa.
- Masana'antun Abinci da Magunguna: Don layukan samarwa da ke buƙatar tsaftar kayan aiki mai yawa.
