Ukuhlaziywa kwezinzuzo zemicu ye-basalt yamapayipi anengcindezi ephezulu

I-basalt fiberipayipi elihlanganisiwe eliphezulu lokucindezela, elinezici zokumelana nokugqwala, isisindo esincane, amandla aphezulu, ukumelana okuphansi kokuthutha uketshezi kanye nempilo ende yesevisi, isetshenziswa kabanzi ku-petrochemical, izindiza, ukwakhiwa kanye neminye imikhakha. Izici zayo eziyinhloko yilezi: ukumelana nokugqwala ku-H2S, CO2, amanzi anosawoti, njll., ukwakheka kwesikali esiphansi, ukwakheka kwengcina ephansi, ukusebenza kahle kokugeleza, ukugeleza kwe-coefficient izikhathi ezingu-1.5 kunepayipi lensimbi, futhi ngesikhathi esifanayo, inamandla amahle kakhulu okusebenza, isisindo esilula, izindleko zokufaka eziphansi, impilo yesevisi yokuklama iminyaka engaphezu kwengu-30, futhi kwamanye amaphrojekthi, ngisho neminyaka engu-50 akukabikho inkinga. Izicelo zayo eziyinhloko yilezi: uwoyela ongahluziwe, igesi yemvelo namapayipi okuhambisa amanzi ahlanzekile; umjovo wamanzi endle, ipayipi likawoyela we-downhole namanye amapayipi anengcindezi ephezulu; amapayipi enqubo ye-petrochemical; amapayipi okuhambisa indle kanye nokuhlanza amanzi angcolile; hot springs pipe nokunye.

Inqubo Eyinhloko:
Ukuqhathanisa kanye umehluko phakathii-fiberglasskanye nepayipi le-basalt fiber high pressure:
(1) i-fiber ecacile efanayo, i-pavement efanayo, okokusebenza okufanayo kanye nenqubo yayo yokuqinisekisa umehluko phakathi kwengcindezi ye-hydrostatic ye-basalt fiber/glass fiber pipeline (DN50PN7, isibonelo, i-EP/CBF ukumelana nokucindezela okungaba ngu-30MPa, EP/GF ukumelana nokucindezela okungaba ngu-25MPa); izinga elifanayo lokucindezela, i-basalt fibre ehlobene ne-glass fiber ukunciphisa umgwaqo we-10%, i-20% ukuze uqinisekise izinga langempela lokumelana nokucindezela kwe-hydrostatic (kuya ku-DN50PN7) Ngokwesibonelo, nciphisa izingqimba ezingu-2 ze-EP / CBF ukumelana nokucindezela okungaba ngu-25MPa).
(2) Ukuhlolwa kokugcina ngemva kokunciphisa indlela egandayiwe yokunciphisa ukusetshenziswa okuphelele kwezinto ezingavuthiwe ukuze kuncishiswe izindleko zomkhiqizo kulawulwa, izinga lokumelana nengcindezi yepayipi lisahlangabezana nezidingo zokuklama, izindleko zepayipi.ipayipi le-fiberglassngokuhlobene nokungakhuphuki okubalulekile.

Izinzuzo zokusebenza kwepayipi le-basalt fiber high:
(1) ukumelana nokugqwala okuhle kakhulu
I-basalt fiberuhlaka lwamapayipi okucindezela okukhulu luhlukaniswe ungqimba lwe-lining, ungqimba lwesakhiwo kanye nongqimba olungaphandle oluvikelayo lwezingxenye ezintathu. Phakathi kwazo, ungqimba lwe-lining lunokuqukethwe okuphezulu kwe-resin, ngokuvamile okungaphezu kuka-70%, futhi okuqukethwe kwe-resin koqweqwe lwawo lwangaphakathi olucebile nge-resin kuphezulu cishe ku-95%. Uma kuqhathaniswa nepayipi lensimbi, linokumelana nokugqwala okuphakeme kakhulu, njengezinhlobonhlobo zama-acids aqinile nama-alkali, izinhlobonhlobo zikasawoti wezinto ezingaphili, i-oxidizing media, i-hydrogen sulfide, i-carbon dioxide, ama-surfactants ahlukahlukene, izixazululo ze-polymer, izinhlobonhlobo zezinyibilikisi eziphilayo, njll. i-alkali, ne-HF ayifakiwe)
(2) Ukumelana nokukhathala okuhle nempilo ende yenkonzo
Impilo yesevisi yokuklama ipayipi le-Basalt fibre high-pressure ingaphezu kweminyaka engama-20, futhi empeleni, ngokuvamile ngemva kweminyaka engaphezu kwengu-30 yokusetshenziswa isaqinile, futhi empilweni yayo yesevisi ayilungiswa.
(3) Amandla aphezulu okuthwala ingcindezi
Izinga lokucindezela elivamile lei-basalt fiberipayipi elinengcindezi ephezulu lingu-3.5MPa-25MPa (kufika ku-35 MPa, ngokuya ngogqinsi lodonga nokubala), uma kuqhathaniswa namanye amapayipi angewona awensimbi, amandla amelana nokucindezela angaphezulu.
(4) Isisindo esincane, ukufakwa kalula nokuhamba
I-basalt fiber high-pressure pipe ethize icishe ibe ngu-1.6, ipayipi lensimbi kuphela noma ipayipi lensimbi elicijile elingu-1/4 ~ 1/5, isicelo esisebenzayo sibonisa ukuthi, ngaphansi kwengcindezi efanayo yangaphakathi, ububanzi obufanayo, ubude obufanayo bepayipi le-FRP, isisindo salo singama-28% wepayipi lensimbi.
(5) amandla aphezulu, izakhiwo zemishini ezinengqondo
I-basalt fiber high-pressure pipe axial tensile amandla ka-200 ~ 320MPa, eduze kwepayipi lensimbi, kodwa ngaphezu kwamandla izikhathi ezingaba ngu-4, ekwakhiweni kwesakhiwo, isisindo sepayipi singancishiswa kakhulu, ukufakwa kulula kakhulu.
(6) Ezinye izakhiwo:
Akulula ukukala kanye ne-wax, ukumelana nokugeleza okuphansi, izakhiwo ezinhle zokufaka ugesi kagesi, uxhumano olulula, amandla aphezulu, ukuqhutshwa kokushisa okuphansi, ukucindezeleka okuphansi kokushisa.
