Chitoliro cha API vs Chitoliro cha 3PE

Mu mapulojekiti akuluakulu a uinjiniya monga mafuta, gasi wachilengedwe, ndi madzi a m'mizinda, mapaipi amakhala ngati maziko a kayendetsedwe ka mayendedwe, ndipo kusankhidwa kwawo kumatsimikizira mwachindunji chitetezo cha pulojekitiyi, ndalama zogwiritsira ntchito, komanso kulimba kwake. Chitoliro cha API ndi chitoliro cha 3PE, zinthu ziwiri za mapaipi zomwe zimagwiritsidwa ntchito kwambiri, nthawi zambiri zimayikidwa patsogolo ndi magulu a uinjiniya. Komabe, zimasiyana kwambiri pamiyeso ya kapangidwe, mawonekedwe a magwiridwe antchito, ndi zochitika zoyenera. Kumvetsetsa bwino makhalidwe awo ndikofunikira kwambiri kuti ntchitoyo ikhale yabwino.

Tanthauzo ndi Zochitika Zofunikira pa Ntchito

Chitoliro chachitsulo cha API 5L-Chitoliro chachitsulo

Chitoliro cha API, chidule cha "American Petroleum Institute Standard Steel Pipe," chimapangidwa motsatira miyezo yapadziko lonse lapansi mongaChitoliro chachitsulo cha API 5L. Imapangidwa ndi chitsulo champhamvu kwambiri ndipo imapangidwa kudzera mu njira zozungulira kapena zowotcherera zopanda msoko. Mphamvu zake zazikulu zili mu mphamvu zake zopanikiza komanso zokoka, zomwe zimapangitsa kuti igwiritsidwe ntchito kwambiri pa ntchito zopanikiza kwambiri monga mapaipi amafuta ndi gasi akutali komanso manifolds a gasi wa shale. Kukhazikika kwake pakupanga kutentha kwambiri kuyambira -40°C mpaka 120°C kumapangitsa kuti ikhale gawo lofunika kwambiri pa kayendedwe ka mphamvu.

Chitoliro chachitsulo cha 3PE -GROWAL GULU

Chitoliro cha 3PE chimayimira "chitoliro chachitsulo cha polyethylene chotsutsana ndi dzimbiri cha magawo atatu." Chimagwiritsa ntchito chitoliro chachitsulo wamba ngati maziko, chokhala ndi kapangidwe kachitatu kotsutsana ndi dzimbiri komwe kali ndi epoxy powder coating (FBE), guluu, ndi polyethylene. Kapangidwe kake kapakati kamayang'ana kwambiri kuteteza dzimbiri, kukulitsa kwambiri moyo wa ntchito ya chitoliro mwa kupatula tizilombo toyambitsa matenda ndi ma electrolyte kuchokera pansi pa chitoliro chachitsulo. M'malo owononga kwambiri monga madzi a m'matauni, kuyeretsa zimbudzi, ndi kunyamula mankhwala amadzimadzi, chitoliro cha 3PE chimatha kukhala ndi moyo wautumiki wa zaka zoposa 50, zomwe zimapangitsa kuti chikhale njira yodziwika bwino yolimbana ndi dzimbiri pomanga mapaipi apansi panthaka.

Kuyerekeza Magwiridwe Abwino Kwambiri

Kuchokera pakuwona magwiridwe antchito apakati, mapaipi awiriwa amasiyana momveka bwino pa malo awo. Ponena za makhalidwe a makina, mapaipi a API nthawi zambiri amakhala ndi mphamvu yotulutsa mphamvu yoposa 355 MPa, yokhala ndi magiredi ena amphamvu kwambiri (mongaAPI 5L X80) kufika pa 555 MPa, yokhoza kupirira kupsinjika kopitilira 10 MPa. Koma chitoliro cha 3PE, chimadalira kwambiri chitoliro chachitsulo chapansi kuti chikhale ndi mphamvu, ndipo gawo loletsa dzimbiri palokha silikhala ndi mphamvu yonyamula kupsinjika, zomwe zimapangitsa kuti likhale loyenera kwambiri ponyamula kupanikizika kwapakati ndi kotsika (nthawi zambiri ≤4 MPa).

Mapaipi a 3PE ali ndi ubwino waukulu pakulimbana ndi dzimbiri. Kapangidwe kake ka magawo atatu kamapanga chotchinga chachiwiri cha "kudzipatula mwakuthupi + chitetezo cha mankhwala." Mayeso opopera mchere akuwonetsa kuti kuchuluka kwa dzimbiri kwawo ndi 1/50 yokha kuposa kwa chitoliro wamba chachitsulo chopanda kanthu.Mapaipi a APIZingathe kutetezedwa ku dzimbiri kudzera mu galvanizing ndi penti, mphamvu zawo m'malo obisika kapena pansi pa madzi zikadali zochepa poyerekeza ndi mapaipi a 3PE, zomwe zimafuna njira zina zotetezera cathodic, zomwe zimawonjezera ndalama zomwe zimagwiritsidwa ntchito pa ntchito.

Njira Zosankhira ndi Zochitika Zamakampani

Kusankha polojekiti kuyenera kutsatira mfundo ya "kuyenerera kwa zochitika": Ngati chonyamuliracho chili ndi mafuta kapena gasi wopanikizika kwambiri, kapena malo ogwirira ntchito akukumana ndi kusinthasintha kwakukulu kwa kutentha, mapaipi a API ndi omwe amakondedwa, ndipo magiredi achitsulo monga X65 ndi X80 amafanana ndi kuchuluka kwa kupanikizika. Pa kunyamula madzi obisika kapena mankhwala otayira, mapaipi a 3PE ndi njira yotsika mtengo, ndipo makulidwe a gawo loletsa dzimbiri ayenera kusinthidwa malinga ndi kuchuluka kwa dzimbiri la nthaka.

Masiku ano makampani akugwiritsa ntchito njira ya "kusakanikirana kwa magwiridwe antchito." Makampani ena akuphatikiza zinthu zolimba kwambiri za chitoliro cha API ndi kapangidwe kake kachitatu kotsutsana ndi dzimbiri ka chitoliro cha 3PE kuti apange "chitoliro chotsutsana ndi dzimbiri champhamvu kwambiri." Mapaipi awa amakwaniritsa zofunikira za kutumiza kwamphamvu kwambiri komanso kuteteza dzimbiri kwa nthawi yayitali. Mapaipi awa agwiritsidwa ntchito kale kwambiri popanga mafuta ndi gasi m'nyanja yakuya komanso mapulojekiti osinthira madzi pakati pa beseni. Njira yatsopanoyi imapereka yankho labwino kwambiri pakupanga mapaipi.
