Ongororo yezvakanakira basalt fibers kune yakakwirira-kudzvanywa mapaipi

Basalt fibercomposite high-pressure pombi, iyo ine hunhu hwekurarisa, huremu huremu, simba rakawanda, kushomeka kwekutakura zvinwiwa uye hupenyu hurefu hwesevhisi, inoshandiswa zvakanyanya mupetrochemical, ndege, kuvaka uye mamwe minda. Mamiriro ayo makuru ndeaya: kusagadzikana kwemarara kuH2S, CO2, mvura yemunyu, nezvimwewo, kudzika kwakadzika, kugadzirwa kwewakisi, kuyerera kwakanaka, kuyerera kwekoefficient inosvika ka1.5 pane yepombi yesimbi, uye panguva imwecheteyo, ine simba rakanakisa remuchina, uremu hwakaderera, mutengo wakaderera wekuisa, dhizaini yehupenyu hweanopfuura makore makumi matatu, uye mune mamwe mapurojekiti, uye kunyange makore 50 haisati yashandiswa. Zvishandiso zvayo zvikuru ndezvi: mafuta asina kuchena, gasi rechisikigo uye mapaipi ekufambisa mvura yakachena; jekiseni remvura yetsvina, pombi yemafuta anodzika pasi uye mamwe mapaipi anodzvinyirira zvakanyanya; petrochemical process mapaipi; pombi dzepaipi dzepaipi yetsvina yemumunda wetsvina uye mapombi ekurapa mvura; hot springs pipe uye zvichingodaro.

Main process:
Kuenzanisa uye kusiyana pakatifiberglassuye basalt fiber high pressure pipe:
(1) iyo yakafanana dhizaini faibha, iyo yakafanana pavement, midziyo yakafanana uye maitiro ayo ekuona musiyano pakati peiyo hydrostatic pressure yebasalt fiber / girazi fiber pipeline (DN50PN7, semuenzaniso, EP / CBF pressure resistance yeanenge 30MPa, EP / GF pressure resistance inenge 25MPa); iyo yakafanana nhanho yekumanikidza, iyo basalt fiber inoenderana negirazi fiber kuderedza mugwagwa we10%, 20% kuratidza iyo chaiyo nhanho ye hydrostatic pressure resistance (kusvika kuDN50PN7) Semuenzaniso, kuderedza 2 layers EP / CBF pressure resistance inenge 25MPa).
(2) Muedzo wekupedzisira mushure mekudzikisa nzira yekumisa kudzikisa kushandiswa kwese kwemidziyo yekudzikisa mutengo wechigadzirwa yakadzorwa, iyo nhanho yekumanikidza kuramba kwepombi ichiri kusangana nezvinodiwa zvekugadzira, mutengo wefiberglass pombizvine chekuita nekusawedzera kwakakosha.

Basalt fiber yakakwira kumanikidza pombi kuita zvakanakira:
(1) yakanakisa corrosion resistance
Basalt fiberhigh-pressure pipeline structure yakakamurwa kuita lining layer, structural layer uye yekunze inodzivirira layer yezvikamu zvitatu. Pakati pazvo, iyo lining layer ine yakakwira resin yemukati, kazhinji inodarika 70%, uye iyo resin yemukati yemukati resin-rich layer yakakwira kusvika 95%. Kana ichienzaniswa nepombi yesimbi, ine yakawanda yepamusoro-soro yekudzivirira, yakadai semhando dzakasiyana-siyana dzakasimba uye alkalis, zvakasiyana-siyana zvemunyu, oxidizing media, hydrogen sulfide, carbon dioxide, zvakasiyana-siyana zve surfactants, polymer solutions, zvakasiyana-siyana zvinonyungudutsa organic, nezvimwewo, chero bedzi sarudzo ye resin yakanaka resin matrix matrix, high pressure inogona kuva yebasalt refu, high pressure inogona kuva yebasalt refu. alkali, uye HF isina kubatanidzwa)
(2) Zvakanaka kuneta kuramba uye hupenyu hurefu hwebasa
Basalt fiber yakakwirira-kumanikidza pombi dhizaini yehupenyu hwesevhisi yakakura kupfuura makore makumi maviri, uye kutaura zvazviri, kazhinji mushure memakore anopfuura makumi matatu ekushandiswa ichiri yakasimba, uye muhupenyu hwayo hwesevhisi haina kugadzirisa.
(3) High pressure-kutakura simba
The normal pressure level yebasalt fiberpombi inotsikirira yakakwira ndeye 3.5MPa-25MPa (inosvika 35 MPa, zvichienderana nekukora kwemadziro uye kuverenga), zvichienzaniswa nemamwe mapaipi asiri esimbi, simba risingapindire kukwira.
(4) Huremu huremu, kuiswa nyore uye kutakura
Basalt fiber high-pressure pombi yakanangana negiravhiti inenge 1.6, pombi yesimbi chete kana pombi yakakandwa yesimbi 1/4 ~ 1/5, kushanda kunoratidza kuti, pasi pekumanikidzwa kwakafanana kwemukati, dhayamita imwechete, kureba kwakafanana kweFRP pombi, uremu hwayo hunenge 28% yepombi yesimbi.
(5) simba rakakwirira, rinonzwisisika mechanical properties
Basalt faibha yakakwira-kudzvanywa pombi axial tensile simba re200 ~ 320MPa, padyo nesimbi pombi, asi kupfuura simba renguva dzinenge 4, mukugadzirwa kwemaitiro, huremu hwepombi hunogona kuderedzwa zvakanyanya, kuiswa kuri nyore kwazvo.
(6) Zvimwe zvinhu:
Haisi nyore kuyera uye wakisi, kushomeka kuyerera kuramba, yakanaka magetsi ekudzivirira zvivakwa, nyore kubatana, simba rakawanda, yakaderera thermal conductivity, yakaderera thermal kusagadzikana.
