O fafo o le PE ua fa'apipi'iina paipa palasitika
I fafo PE fa'apipi'i fa'apipi'iina paipa palasitika, fa'apipi'i (ta'avale) palasitika tu'ufa'atasi paipa u'amea e aunoa ma le fa'atapula'a fa'atapula'aina, e mafai fo'i ona filifilia fa'alilolilo le mafiafia o le fa'alava, e tusa ai ma tulaga fa'aleaga, filifili mafiafia lining eseese, umi e mafai fo'i ona o'o i le 6-12. mita;O le lautele nominal tutusa, faʻapipiʻiina (taʻavale) palasitika faʻapipiʻi paipa paipa e masani lava i le va o le 0.5-1mm, lamolemole luga o le paipa, e le gata o le faʻafefeteina e laʻititi, ma e laʻititi foʻi le faʻafefe, o le gau o le vai i totonu o le paipa e laʻititi, e tele le tafega felauaiga, e ausia ai le faʻaolaina o le malosi.I tausaga talu ai nei, o le anti-corrosion spiral paipa uʻamea o loʻo faʻaaogaina lautele i le fausiaina o le vai ma alavai, inu vai tufatufaina pipelines inisinia, pulea afi, mo le sili atu afi paipa paipa uʻamea aʻo leʻi faʻaaogaina vevela paipa uʻamea uamea, tele nuu, faletalimalo, fale ofisa o loʻo faʻaaogaina nei epoxy paʻu anticorrosive paipa uamea ma itu uma e lua palasitika faʻapipiʻiina o loʻo faʻaogaina i totonu ma fafo e pei o mea paipa afi, o lona foliga matagofie ma umi, Ua avea ma oloa tele o alamanuia faʻaalia i le 21st seneturi.PE i totonu EP fa'apipi'i palasitika fa'alava fa'atau fa'apolofesa fa'atauga fa'apolofesa fa'apipi'i palasitika fa'apipi'i fa'amalama afi ma suia epoxy resin pa'u, o le vevela o le fa'alava e sili atu, i le fa'aaogaina umi e le mu, aua le fa'amalulu.
O fafo Pe Composite Ufiufi Paila Paipa, Fa'amanuiaga
O le ata vali o le epoxy powder anticorrosive paipa uʻamea e faigata, vai faʻafefe ma e le oona.Faʻapipiʻi malosi, faʻapipiʻi lelei i le va o ata vali ma ata vali.E sili atu le anti-ele ma le vai, o le faʻaaogaina o mea e sili ona lelei e faʻamaʻi ai, e faʻamautinoa ai lona faʻatinoina o le anti-rust.O lo'o i ai le malosi fa'ainisinia lelei, ata tifaga faigata, fa'afefe abrasion ma a'afiaga.maualuga mea mautu, ata mafiafia.O le molecular structure o le epoxy powder anticorrosive steel pipe o loʻo faʻaalia e vaega epoxy malosi i le filifili mole, lea e mafai ona maua i le pito, ogatotonu poʻo le mama fausaga o le filifili mole.
Ona o vaega epoxy malosi i totonu o le fausaga mole, e mafai ona latou faʻafesoʻotaʻi faʻatasi ma ituaiga eseese o vailaʻau faʻamalolo e fausia ai polymers e le mafai ona faʻaaogaina ma le faʻaogaina o fesoʻotaʻiga e tolu-auala.E masani ona fa'aogaina le pa'u pa'u o le thermosetting i atunu'u 'ese'ese: pa'u pa'u epoxy, pa'u pa'u epoxy phenolic, pa'u pa'u polyester, pa'u pa'u epoxy-polyester.Faatasi ai ma i latou, o le epoxy paʻu paʻu o le ituaiga muamua o le talosaga, o le gaosiga o loʻo i ai nei o le paʻu palasitika paʻu, faʻaaogaina lautele i le faʻaogaina o le eletise eletise, i le faʻaofuofu teuteu e taʻalo se tulaga taua tele;Ona o le maualuga o le faʻamaʻiina o vailaʻau, o le epoxy phenolic paʻu paʻu e masani ona faʻaaogaina mo le faʻafefeteina.
O mea fa'apipi'i pa'u vevela e masani lava
Polyethylene paʻu paʻu, POLYvinyl chloride paʻu paʻu, polypropylene paʻu paʻu paʻu, chlorinated polyether paʻu paʻu, nylon paʻu paʻu, polyphenylene sulfide paʻu paʻu, ma isi, o nei paʻu paʻu vevela e iai le lelei ma le le lelei.Thermosetting plastics e sili atu le fofoina o le leveling ma le susu ona o lo latou mamafa mole mole laiti, lea e mafai ai ona latou pipii malosi i le tino o le paipa pe a faʻapipiʻi faʻauʻu uamea, ma e mafai ona faʻapipiʻiina paipa uamea e maua ai se ata palasitika lamolemole.E masani ona faʻaaogaina palasitika thermosetting: epoxy resin, phenolic resin, amino resin ma isi.O le mafiafia o le puipui faʻapipiʻi e i le va o le 100 microns ma le 500 microns, masani lava 350 microns.
I fafo o le PE fa'apipi'i fa'apipi'i paipa palasitika, 1. Soifua Maloloina, e le o'ona, leai se scaling, leai se fa'atupuina o microorganisms, fa'amautinoa le lelei o le suavai 2. 3. O le fa'apipi'iina o le fa'agasologa e matua, faigofie ma vave, ma le feso'ota'iga ma paipa galvanized masani e. tutusa lava.4. Lelei le tetee i le tau.5. puipui paipa lamolemole, faʻaleleia le faʻaleleia o le faʻaleleia, ola umi o auaunaga.
O fafo PE ua fa'apipi'iina paipa palasitika fa'apipi'i, Feso'ota'iga faiga:feso'ota'iga filo: fa'aoga le uaea milo fa'ameamea po'o le masini lima uaea eletise e fa'agasolo ai filo paipa, fa'alogo lelei i le fa'alili i le taimi o le gaosiga;Feso'ota'iga Flange, fua i luga o le 'upega tafa'ilagi, fa'asologa o laina paipa laina tasi fa'asologa o fa'afanua, fa'apipi'iina fa'apipi'i, fa'apipi'i palasitika, ona momoli atu lea i le nofoaga fa'apipi'i;E le faʻapipiʻiina, faʻapipiʻiina paipa uʻamea palasitika ma mea faʻapipiʻi paipa e mafai ona faʻaogaina i totonu o le fanua, faʻapipiʻiina o le flange, faʻapipiʻiina o paipa, ona faʻamavaeina lea mo le faʻapipiʻiina, faʻapipiʻiina le gaosiga o palasitika, ona ave lea i le nofoaga faʻapipiʻi;O paipa palasitika ua mae'a fa'apipi'iina e tatau ona fa'asili;E tatau ona oomiina ala e ala i le masini taʻavale, ma e tatau ona o gatasi ma tulaga talafeagai.
