FRP Flange
Tsananguro yeChigadzirwa
FRP (Fiberglass Reinforced Plastic) flanges i ring-shaped connectors dzinoshandiswa kubatanidza mapaipi, mavharuvhu, mapombi, kana zvimwe zvishandiso kugadzira system yakakwana yemapaipi. Dzinogadzirwa nezvinhu zvakabatana zvinosanganisira girazi fibers sezvinhu zvinosimbisa uye synthetic resin se matrix. Dzinogadzirwa uchishandisa maitiro akadai sekuumba, kurongedza nemaoko, kana kumonera filament.
Zvimiro zveChigadzirwa
Nekuda kwekugadzirwa kwavo kwakasiyana, maFRP flanges anopa mabhenefiti akakosha pamusoro pemaflange esimbi echinyakare:
- Kuramba Kuora Kwakanaka: Chinhu chinonyanya kuzivikanwa chemaFRP flanges kugona kwawo kuramba ngura kubva mumakemikari akasiyana-siyana, kusanganisira maacid, alkalis, munyu, uye organic solvents. Izvi zvinoita kuti ashandiswe zvakanyanya munzvimbo dzinotakurwa mvura dzinoora, senge mumakemikari, peturu, simbi, magetsi, mishonga, uye maindasitiri ezvekudya.
- Huremu Hwakareruka Uye Simba Rakanyanya: Huremu hweFRP hunowanzova 1/4 kusvika 1/5 chete yesimbi, asi simba rayo rinogona kuenzaniswa. Izvi zvinoita kuti zvive nyore kutakura nekuisa, uye zvinoderedza mutoro wese pahurongwa hwemapaipi.
- Kudzivirira Kwakanaka Kwemagetsi: FRP chinhu chisingafambise mhepo, zvichiita kuti maFlange eFRP ave nehunyanzvi hwakanaka hwekudzivirira magetsi. Izvi zvakakosha munzvimbo dzakatarwa kudzivirira ngura yemagetsi.
- Kuchinjika Kwazvo Kwemagadzirirwo: Nekugadzirisa fomura ye resin uye kurongeka kwemafiber egirazi, ma flange eFRP anogona kugadzirwa kuti asvike kune zvinodiwa chaizvo zvekudzivirira tembiricha, kumanikidzwa, uye ngura.
- Mutengo Wakaderera Wekugadzirisa: Maflange eFRP haaite ngura kana kukura, zvichiita kuti ashande kwenguva refu uye anoderedza zvakanyanya mari yekugadzirisa nekutsiva.
Rudzi rweChigadzirwa
Zvichienderana nemaitiro avo ekugadzira uye chimiro chechimiro, maFRP flanges anogona kugoverwa mumhando dzakasiyana:
- Flange yeChidimbu Chimwe (Chakakosha): Rudzi urwu rwakagadzirwa seyuniti imwe chete ine muviri wepombi, zvichipa chimiro chakasimba chakakodzera kushandiswa kwesimba rakaderera kusvika pakati nepakati.
- Flange Yakareruka (Lap Joint Flange): Ine flange rin'i yakareruka, inotenderera zvakasununguka uye mugumo wakasimba papombi. Dhizaini iyi inobatsira kuisa, kunyanya mukubatanidza mapoinzi akawanda.
- Flange Isingaonekwe (Flange Isina Chinhu/Chivharo Chekupedzisira): Inoshandiswa kuvhara magumo epombi, kazhinji yekutarisa sisitimu yepombi kana kuchengetedza nzvimbo yekupindira.
- Socket Flange: Pombi iyi inopinzwa mukati memukati meflange uye yakabatana zvakachengeteka kuburikidza nekubatanidza kwakabatana kana kumonera, zvichiita kuti chisimbiso chishande zvakanaka.

Kuti muwane maburi makuru kana kuti magadzirirwo akagadzirwa nemaoko enyu, ndapota ndibatei kuti mugadzirise maburi enyu.
Zvishandiso zveChigadzirwa
Nekuda kwekudzivirira kwavo ngura zvakanyanya uye simba ravo rakareruka, maFRP flanges anoshandiswa zvakanyanya mu:
- Indasitiri yeMakemikoro: Yemapaipi anotakura makemikari anoparadza akadai seasidhi, alkalis, uye munyu.
- Uinjiniya hwezvakatipoteredza: Mukugadzirisa mvura yakasviba uye michina yekubvisa sarufa negesi inoyerera.
- Indasitiri yeMagetsi: Yemvura inotonhodza uye masisitimu ekubvisa sulfurization/denitrification mumafekitori emagetsi.
- Uinjiniya hweMarine: Mukugadzirisa mvura yegungwa uye masisitimu emapaipi engarava.
- Maindasitiri Ezvekudya Nemishonga: Kune mitsetse yekugadzira inoda kuchena kwakanyanya kwezvinhu.
