Ukusetshenziswa kwepayipi le-epoxy resin endaweni yamandla
Ukusetshenziswa kwepayipi le-epoxy resin endaweni yamandla
Enye indawo yokusetshenziswa ingilazi fibre eqiniswe epoxy amapayipi emkhakheni wamandla kusezikhungweni zikagesi. Ngenxa yomugqa wayo oguquguqukayo, ipayipi inokumelana okuhle kokugqoka, ngakho ifanele ipayipi le-flue, futhi impilo yayo yesevisi iphindwe kabili kunepayipi yensimbi. Lapho okuqukethwe komlotha wamalahle kungu-10%, uma ipayipi iphenduka izikhathi ezine (ngaso sonke isikhathi i-angle yokujika ingu-90 °), impilo yesevisi yepayipi yensimbi yiminyaka emibili, futhi i-glass fiber eqiniswe ipayipi ye-epoxy resin iminyaka emine.
Ngaphezu kokusetshenziswa njengepayipi elishisayo, leli payipi lingasetshenziswa nomaphi lapho ukucindezela kungeqi ku-10 bar futhi izinga lokushisa lingeqi ku-65 °C. E-United States, cishe amakhilomitha angu-450 amapayipi epulasitiki aqiniswe ngengilazi afakiwe kuze kube manje ezitshalweni zamandla ezishisayo. Ngo-1975, kwakuhlelwe ukuqhubeka ukufaka amakhilomitha angu-140.
Ngaphezu kokuphila kwenkonzo ende, enye inzuzo ebalulekile yepayipi ye-epoxy eqinisiwe yengilazi isisindo sayo esilula nokufakwa kalula. I-fiber yengilazi eqinisiwe ipayipi ye-epoxy resin ayikwazi ukushiselwa futhi kufanele ixhunywe nama-bolts, noma ifakwe ngama-flanges, futhi amapayipi angabuye axhunywe nge-gluing.
I-epoxy iyinto ethuthukisiwe esetshenziswa ngezindlela eziningi, kusukela ekwakhiweni kuya ekundizakeni komkhathi. Izinamathiselo ze-epoxy zinamathela kahle esikhunjeni se-epoxy esiphulukisiwe. Ngakho-ke, i-gluing ingenye yezindlela ezinokwethenjelwa kakhulu futhi ezongayo zokuhlanganisa amapayipi e-epoxy aqiniswe nge-glass fiber. Ububi be-gluing ukuthi indlela yokuhlola ayiphelele. Ipayipi le-epoxy eliqinisiwe lengilazi elihlanganisiwe manje lingahlolwa ingcindezi. Ezinye izindlela zokuhlola ezingabhubhi (ezilingana nokuhlolwa kwe-X-ray yamapayipi ensimbi) azisetshenziswa okwamanje.
