I-Epoxy FRP Umbhobho waNgaphakathi Ukunyangwa koKufudumeza
Ifayibha ye-epoxy eyomeleziweyo yeplastiki ye-HP imigca yomphezulu kunye ne-downhole tubing iveliswa ngokuhambelana ngqongqo kunye neenkcukacha ze-API.Imveliso yonyaka iza kwi-2000km ubude kunye nobubanzi obusuka kwi-DN40 ukuya kwi-DN300mm.
I-epoxy FRP HP umgca womphezulu une-API emide yokudibanisa intambo ejikelezayo kwizinto ezidibeneyo, ukuxhathisa ukunxiba kwandisa ubomi bokusebenza kombhobho.
I-epoxy FRP ye-downhole tubing luhlobo lwentsebenzo ephezulu, amandla aphezulu e-tensile ye-FRP inxeba lombhobho ngokuchanekileyo ngezixhobo ezilawulwa yidijithali.Ubuchwepheshe bomoya obuqhubela phambili befayibha busetyenziswa ukuqonda amandla awonelisayo afunekayo ekusetyenzisweni komngxuma.
Olona xinzelelo luphezulu lokusebenza kwimigca yomphezulu ye-HP yi-31MPa kunye ne-downhole tubing yi-26MPa.Obona bushushu buphezulu be-ambient ye-aliphatic amine enyangekileyo yombhobho we-epoxy we-FRP yi-85℃ kunye nombhobho we-amine onuka kamnandi onyangekileyo we-epoxy FRP yi-110℃.Imibhobho esebenza kubushushu obuyi-150℃ iyafumaneka ngokwesicelo somthengi.
Iimpawu eziphambili:
• Ubunzima bokukhanya, malunga ne-1/4 yepayipi yensimbi;
• Ukufakwa ngokukhawuleza kunye nokulungeleka phantsi kwazo zonke iimeko zemozulu kwaye ngaphandle kwesidingo se-agent edibeneyo;
• Umphezulu ogudileyo wangaphakathi, ubumanzi obugqwesileyo;
• Ukumelana nomhlwa okuqinileyo kunye nobomi obude bokusebenza;
• Ixabiso eliphantsi lofakelo;
• Ukubekwa kwewax kunye nesikali.
