Kugwiritsa ntchito chitoliro cha epoxy resin pamagetsi
Malo ena ogwiritsira ntchito galasi CHIKWANGWANI analimbitsa epoxy mapaipi m’gawo lamagetsi ali m’mafakitale amagetsi. Chifukwa cha kusinthasintha kwake, chitolirocho chimakhala ndi kukana kwabwino, kotero ndi koyenera chitoliro cha flue, ndipo moyo wake wautumiki ndi wotalika kawiri kuposa wa chitoliro chachitsulo. Pamene phulusa la malasha lili 10%, ngati chitoliro chitembenuzidwira kanayi (nthawi iliyonse yotembenuka ndi 90 °), moyo wautumiki wa chitoliro chachitsulo ndi zaka ziwiri, ndipo chitoliro cha galasi cholimbitsa epoxy resin chitoliro ndi zaka zinayi.
Kuphatikiza pa kugwiritsidwa ntchito ngati chitoliro cha chitoliro, chitolirochi chingagwiritsidwe ntchito kulikonse kumene kupanikizika sikudutsa 10 bar ndipo kutentha sikudutsa 65 °C. Ku United States, pafupifupi makilomita 450 a mapaipi apulasitiki opangidwa ndi magalasi opangidwa ndi magalasi ayikidwa mpaka pano pamafakitale ambiri opangira magetsi. Mu 1975, anakonza kupitiriza kukhazikitsa 140 makilomita.
Kuphatikiza pa moyo wautali wautumiki, mwayi wina wofunikira wa chitoliro cha galasi cholimbidwa ndi epoxy ndi kulemera kwake komanso kuyika kosavuta. Chitoliro chagalasi chomwe chimalimbitsa chitoliro cha epoxy resin sichingathe kuwotcherera ndipo chiyenera kulumikizidwa ndi mabawuti, kapena kuyikidwa ndi ma flanges, ndipo mapaipi amathanso kulumikizidwa ndi gluing.
Epoxy ndi zinthu zapamwamba zomwe zimagwiritsidwa ntchito m’njira zambiri, kuyambira pakumanga kupita kumlengalenga. Zomatira za epoxy zimamatira bwino ku nkhungu zochiritsidwa za epoxy. Choncho, gluing ndi imodzi mwa njira zodalirika ndi ndalama kujowina galasi CHIKWANGWANI analimbitsa mipope epoxy. Kuipa kwa gluing ndikuti njira yoyesera si yangwiro. Chitoliro chagalasi chophatikizidwa cholimbitsa epoxy chikhoza kuyesedwa. Njira zina zoyesera zosawononga (zofanana ndi kuyesa kwa X-ray kwa mapaipi achitsulo) sizikugwiritsidwa ntchito.
