Kuongororwa kwezvakanaka zvebasalt fibers zvemapaipi ane kumanikidzwa kwakanyanya

Basalt faibhaPombi ine simba guru remagetsi, ine hunhu hwekudzivirira ngura, huremu hwakareruka, simba guru, simba shoma rekutakura mvura uye hupenyu hurefu hwebasa, inoshandiswa zvakanyanya mu petrochemical, ndege, kuvaka nedzimwe nzvimbo. Zvinhu zvayo zvikuru ndeizvi: kudzivirira ngura kuH2S, CO2, mvura yemunyu, nezvimwewo, kuunganidzwa kwakaderera, kuumbwa kwewakisi kwakaderera, kushanda zvakanaka kwekuyerera, kuyerera kwemvura kwakapetwa ka1.5 pane pombi yesimbi, uye panguva imwe chete, ine simba rakanaka remakanika, huremu hwakareruka, mutengo wakaderera wekuisa, hupenyu hwebasa rekugadzira hweanopfuura makore makumi matatu, uye mune mamwe mapurojekiti, uye kunyangwe kushandiswa kwemakore makumi mashanu hakusati kuri dambudziko. Mashandisirwo ayo makuru ndeaya: mafuta asina kuchena, gasi rechisikigo uye mapaipi ekutumira mvura yakachena; jekiseni remvura yetsvina, mapaipi emafuta emugomba uye mamwe mapaipi ane simba guru; mapaipi e petrochemical process; mapaipi etsvina yemumunda wemafuta uye mapaipi ekurapa mvura yakasviba; mapaipi emvura inopisa nezvimwewo.

Maitiro Makuru:
Kuenzanisa uye musiyano uripo pakatifiberglassuye pombi yekumanikidza yakakwira yebasalt fiber:
(1) faibha imwecheteyo, nzira imwe chete, michina yakafanana uye maitiro ayo ekusimbisa mutsauko uripo pakati pekumanikidzwa kwehydrostatic kwepombi yefiber yebasalt fiber/girazi (DN50PN7, semuenzaniso, kuramba kwekumanikidzwa kweEP/CBF kweinenge 30MPa, kuramba kwekumanikidzwa kweEP/GF kweinenge 25MPa); chiyero chimwe chete chekumanikidzwa, faibha yebasalt ichienzaniswa nefaibha yegirazi kuderedza nzira ye10%, 20% kusimbisa chiyero chaicho chekusagadzikana kwehydrostatic (kuna DN50PN7) Semuenzaniso, deredza 2 layers EP / CBF kumanikidzwa kweinenge 25MPa).
(2) Muedzo wekupedzisira mushure mekuderedza nzira yekufamba netsoka yekuderedza kushandiswa kwezvinhu zvakagadziriswa kuderedza mitengo yezvigadzirwa wadzorwa, huwandu hwekudzvinyirirwa kwepombi huchiri kusangana nezvinodiwa zvekugadzira, mutengo wepombi yefiberglasszvichienzaniswa nekusava nekuwedzera kwakakosha.

Basalt fiber yakakwira kumanikidzwa kwepombi mashandiro akanakira:
(1) kudzivirira ngura kwakanyanya
Basalt faibhaMaumbirwo emapaipi ane kumanikidzwa kwakanyanya akakamurwa kuita lining layer, structural layer uye ekunze protective layer ine zvikamu zvitatu. Pakati pazvo, lining layer ine resin yakawanda, inowanzo pfuura 70%, uye resin iri mukati mayo ine resin yakawanda inosvika 95%. Kana ichienzaniswa nepombi yesimbi, ine resistance yakakura yengura, senge maacids akasimba nealkalis, munyu we inorganic, oxidizing media, hydrogen sulfide, carbon dioxide, ma surfactants akasiyana-siyana, polymer solutions, organic solvents dzakasiyana-siyana, nezvimwewo, chero bedzi sarudzo ye resin matrix yakanaka, high pressure pipeline ye basalt fibers inogona kuramba kwenguva refu (concentrated acid, strong alkali, uye HF haibatanidzwi)
(2) Kuramba kuneta zvakanaka uye hupenyu hurefu hwebasa
Basalt faibha ine kumanikidzwa kwepamusoro-soro magadzirirwo emapaipi anorarama makore anopfuura makumi maviri, uye kutaura zvazviri, kazhinji mushure memakore anopfuura makumi matatu ekushandiswa, ichiri kushanda, uye muhupenyu hwayo hwebasa haina kugadziriswa.
(3) Kukwanisa kusimbaradza kumanikidzwa kwakanyanya
Kumanikidzwa kwakajairikafaibha yebasaltpombi ine kumanikidzwa kwakanyanya i3.5MPa-25MPa (kusvika 35 MPa, zvichienderana nekukora kwemadziro uye kuverengwa kwawo), zvichienzaniswa nedzimwe pombi dzisiri dzesimbi, kugona kwayo kunodzivirira kumanikidzwa kwakakwira.
(4) Huremu hushoma, nyore kuisa uye kutakurwa
Basalt fiber high-pressure pipe giravhiti chaiyo inenge 1.6, pombi yesimbi chete kana pombi yesimbi yakakandwa 1/4 ~ 1/5, kushanda kunoratidza kuti, pasi pekumanikidzwa kwakafanana kwemukati, dhayamita imwe chete, kureba kwakafanana kwepombi yeFRP, huremu hwayo hunenge 28% yepombi yesimbi.
(5) simba rakakwirira, hunhu hwemakanika hunonzwisisika
Basalt fiber high-pressure pombi axial tensile strength ye200 ~ 320MPa, iri pedyo nepombi yesimbi, asi simba rayo rinodarika kanenge ka4, mukugadzirwa kwechimiro, huremu hwepombi hunogona kuderedzwa zvakanyanya, kuisa kuri nyore kwazvo.
(6) Zvimwe zvinhu:
Hazvisi nyore kuyera uye wakisi, hazvipindi mvura yakawanda, zvine hunhu hwakanaka hwekudzivirira kupisa, kubatana kuri nyore, simba rakawanda, kufambisa mvura shoma, uye kushushikana kwekupisa kushoma.
