Mukuvaka simba pasi rose nekuvaka zvivakwa, kushanda kwakachengeteka kwenguva refu kwemasisitimu emapombi kwakakosha zvikuru. Tekinoroji yekudzivirira ngura yemapaipi, sechisungo chikuru chekuona kuti achishanda kwenguva yakareba sei, kurongeka kwawo uye kudzora mashandiro zvinokanganisa zvakananga kuvimbika kwese uye hupfumi hwepurojekiti. Pakati pavo,Maitiro Ekuvhara eFBE(Fusion Bonded Epoxy Coating Standards) senzira yakakosha yehunyanzvi inoshandiswa zvakanyanya neindasitiri, inopa hwaro hwesainzi, hwakarongeka uye hunosimbiswa hwemhando yekudzivirira ngura pamapaipi.
FBE Coating Standard: Maitiro Akarongwa kubva kuZvinhu kuenda kuMaitiro
Mutemo uyu unotsanangura zvakajeka zvinodiwa zvehunyanzvi zvepurasitiki yakagadzirwa nefekitori ine mativi matatu uye polyethylene ine sintered polyethylene ine mativi maviri. Inoshanda pakudzivirira ngura yemapaipi esimbi nemapombi. Mutemo uyu haungogumiri pakuratidza mashandiro ezvishandiso zvekuputira, asiwo unopa ruzivo rwakakwana rwekushandisa machira, kuongororwa kwemhando, uye rutsigiro rwekuvaka panzvimbo yacho. Chinangwa ndechekuona kuti jira racho rine kunamira kwakanaka, kuramba ngura kwemakemikari, uye kugara kwenguva refu kuburikidza nemaitiro ekugadzira nekuyedza akajairwa, nokudaro richichengetedza basa raro rekudzivirira munzvimbo dzakaoma uye kwenguva yakareba yekushandiswa.
Kugadzira kwepamusoro-soro: Kudzora kwakazara kubva mumuviri wepombi kusvika pakuputira
Semugadziri anotungamira wemapaipi esimbi anotenderera uye zvigadzirwa zvekuputira mapaipi muChina, Cangzhou Spiral Steel Pipe Group Co., Ltd. yagara ichiisa mitemo yehunyanzvi uye hunyanzvi hwekugadzira zvinhu pakati pekuvandudzwa kwebhizinesi rayo kubvira payakatangwa muna 1993. Kambani iyi iri muCangzhou City, Hebei Province, ine nzvimbo yekugadzira inofukidza nzvimbo ye350,000 square metres, uye huwandu hwezvinhu zvayo zvinosvika mamiriyoni 680 yuan. Ine kugona kwekugadzira kwegore negore kwematani 400,000 uye kukosha kwekugadzirwa kwegore negore kwe1.8 bhiriyoni yuan. Zvichibva pakutevedzera zvakanyanya mitemo yepasi rose neyemuno yeFBE Coating, takagadzira sisitimu yekugadzira yakazara kubva pakugadzira mapaipi, kugadzirisa pamusoro kusvika pakushandisa coating uye kuongorora mhando, tichiona kuti pombi yega yega inobuda mufekitori inosangana nezvinodiwa zveinjiniya zvehupenyu hwebasa uye mashandiro ekuchengetedza ekudzivirira ngura.
Kutungamira nezvinodiwa, kushandira pasi rose mukuvandudzwa kwesimba nezvivakwa
Nekuda kuri kuwedzera kwezvinodiwa pasi rose zvekuchengetedzwa kwemapaipi uye kugara kwenguva refu, matekinoroji ekuputira akajairika uye anoshanda zvakanyanya ave chinhu chinowirirana muindasitiri iyi. Hatingoteveri nekushandisa mitemo yeFBE yekuputira chete, asiwo tinobatanidzwa mukukurukurirana nekugadzirisa mitemo ine chekuita nazvo, tichikurudzira kuvandudzwa kwetekinoroji yekuputira kuti ive nemirairo isingakuvadzi nharaunda, inoshanda zvakanyanya, uye ine hungwaru.
Cangzhou Spiral Steel Pipe Group icharamba ichitsigira mashandiro ayo uye ichitungamirirwa netekinoroji. Ichapa zvigadzirwa zvemapaipi emhando yepamusoro zvinoenderana nezvinodiwa zvekubatanidza epoxy coating munzvimbo dzakasiyana siyana dzakadai sekufambisa mafuta negesi, mapurojekiti ekupa mvura, uye rutsigiro rwechivakwa. Izvi zvichabatsira mukusimba kwekugadzira kweChina mukuona kuchengetedzeka kwenguva refu uye kushanda kwakasimba kwezvivakwa zvepasi rose.
