Ukwelapha Ukushisa Kwangaphakathi Kwepayipi le-Epoxy FRP
Imigqa yobuso be-HP eqiniswe nge-epoxy fiber kanye nepayipi elingaphansi komhlaba kukhiqizwa ngokuhambisana nezincazelo ze-API. Umkhiqizo waminyaka yonke ufinyelela ku-2000km ubude kanye nobubanzi obusukela ku-DN40 kuya ku-DN300mm.
Umugqa wobuso be-epoxy FRP HP unoxhumano olujwayelekile lwentambo oluyindilinga oluyindilinga lwe-API ezintweni ezihlanganisiwe, okumelana nokuguguleka kwazo kwandisa impilo yokusebenza kwamapayipi.
Ipayipi le-epoxy FRP downhole liwuhlobo lokusebenza okuphezulu, amandla aphezulu okudonswa kwepayipi le-FRP eligoqwe ngokunembile yimishini elawulwa ngedijithali. Ubuchwepheshe obuthuthukisiwe bomoya obuqhubekayo befayibha busetshenziswa ukuze kufezwe amandla anele okudonswa adingekayo ekusetshenzisweni kwe-downhole.
Ingcindezi ephezulu yokusebenza yemigqa yobuso be-HP ingu-31MPa kanti ipayipi elingaphansi komhlaba lingu-26MPa. Izinga lokushisa eliphezulu le-ambient lepayipi le-aliphatic amine elilungisiwe le-epoxy FRP lingu-85℃ kanti ipayipi le-aromatic amine elilungisiwe le-epoxy FRP lingu-110℃. Amapayipi asebenza ekushiseni okungu-150℃ ayatholakala ngokwesicelo samakhasimende.
Izici Eziyinhloko:
• Isisindo esincane, cishe ingxenye eyodwa kwezine yepayipi lensimbi;
• Ukufakwa okusheshayo nokulula ngaphansi kwazo zonke izimo zezulu futhi ngaphandle kwesidingo se-bonding agent;
• Ubuso obungaphakathi obubushelelezi, ukugeleza okuhle kakhulu;
• Ukumelana nokugqwala okunamandla kanye nokuphila isikhathi eside kokusebenza;
• Izindleko eziphansi zokufaka;
• Ukufakwa okuncane kwe-wax kanye ne-scale.
