1. 3PE puipuiga corrosion
Tolu lapisi PE fausaga e teteʻe ai i le paipa: o le vaega muamua o le epoxy paʻu (FBE> 100um), le vaega lona lua o le pipii (AD) 170 ~ 250um, ma le vaega lona tolu o le polyethylene (PE) 2.5 ~ 3.7mm. O mea e tolu o loʻo tuʻufaʻatasia ma tuʻufaʻatasia faʻatasi ma le paipa uʻamea e fausia ai se faʻapipiʻi sili ona lelei.
Vaitaimi o paipa Φ 60～ Φ tasi le afe fa selau luasefulu
2. 2PE paipa uamea anticorrosive
E lua laulau o le PE anticorrosive fausaga mo paipa, o le vaega muamua o le pipii (AD) ma le vaega lona lua o le polyethylene (PE), o mea e lua ua tuufaatasia, ma o le mafiafia o vaega taitasi e tutusa ma le vaega lona tolu o le PE.
Tulaga masani: SY / t0413-2002 tulaga faʻapitoa mo le polyethylene anticorrosive faʻapipiʻiina o paipa uamea tanumia
GB / t23257-2009 tulaga faʻapitoa mo le polyethylene anticorrosive faʻapipiʻiina o paipa uamea tanumia
3. Pipa u'amea anticorrosive PE tasi
Fa'atusatusaga i le va o le polyethylene tasi-layer ma le polyethylene tolu-layer
Fa'atusatusaga i le va o le polyethylene tasi-layer ma le polyethylene tolu-layer
O le paipa u'amea anticorrosive PE e tasi e fa'aaogaina le fa'agasologa o le fa'apipi'iina (lea e ta'ua o le auala pupuni) e sui ai le paipa u'amea fa'avevela e ala i taimi masani. O le pito i luga o le paipa uamea o se atigipusa o loʻo i ai le paʻu polyethylene, lea e faʻafefe i luga o le puipui pito i fafo o le paipa uʻamea e fausia ai se polyethylene coating. Fa'atonu tulaga CJ / t120-2008 palasitika fa'apipi'iina paipa u'amea tu'ufa'atasia mo le tu'uina atu o vai.
1. Tulaga
O le oloa ua saunia mai le epoxy resin, koale ta pitch, antirust pigmenti, additives ma suiga amine. O le oloa o loʻo i ai le lelei o le vave faʻagogo, faʻapipiʻi lelei, fetuutuunai lelei, faʻapipiʻi lua-vaega ma faʻaoga faigofie. E i ai uiga o le acid, alkali, masima, vai ma suauu tetee.
2. Uiga ma le faaaogaina
O le vali e tuʻufaʻatasia uiga o le malosi faʻainisinia maualuga, malosi faʻapipiʻi tele, vailaʻau vailaʻau faʻafefeteina o le epoxy resin ma vai tetee, microbial teteʻe ma laau aʻa teteʻe o le asphalt. O se faʻapipiʻi faʻapipiʻi faʻapipiʻiina maualuga. O le oloa o loʻo i ai le faʻamaʻi lelei ma le vai.
E faʻatatau i le anti-corrosion o le suauu, kesi ma vai paipa, paipa vai, kesi, paipa, suauʻu refineries, vailaʻau vailaʻau ma otaota otaota. E mafai foʻi ona faʻaaogaina e fai ma anti-corrosion o vaʻa suauʻu i fafo ma vaega i lalo o le sami o vaʻa, faʻapea foʻi ma le anti-corrosion o maina ma meafaigaluega lalo.
High density polyethylene jacket anti-corrosion structure: o le paipa uʻamea o loʻo afifi i mea polyethylene maualuga, lea e maualuga le malosi faʻainisinia ma sili ona lelei le faʻafefeteina, ma e mafai ona puipuia le paipa uʻamea mai mea leaga e mafua mai i fafo i le taimi o felauaiga, faʻapipiʻi ma faʻaoga. Antioxidant, ultraviolet stabilizer, carbon black, ma isi mea e tatau ona faaopoopo i le gaosiga o lima pito i fafo. O le polyethylene pito i fafo lima e faigofie ona matua. Afai e teuina i fafo, e tatau ona ufiufi i tapoleni ma isi mea. O le nofoaga e fa'aputu ai e tatau ona mamao ese mai le fa'apogai o le vevela ma le puna afi. A maeʻa ona faia le paipa uʻamea anti-corrosion, e faʻasaina le faʻaalia i le la ma tineia, a leai o le polyethylene pito i fafo e faigofie ona taʻe ma afaina ai le faʻatinoga o oloa ma le ola tautua.
Epoxy efuefu ua faʻapipiʻiina i le faʻaogaina o le eletise eletise. Ona o le faʻafitauli faʻapipiʻi o le epoxy powder impregnation process, o le impregnation o le epoxy powder e leʻi faʻalauiloaina. I le taimi nei, faʻatasi ai ma le manuia o le atinaʻeina o faʻamaʻi faʻapitoa mo le epoxy powder impregnation o Sanye, o le faʻafitauli faʻapipiʻi o le epoxy powder impregnation ua faʻatoʻilaloina mo le taimi muamua, ma ua amata ona aliali mai le faʻagasologa o le epoxy powder impregnation.
O mea faavae o paipa uʻamea anti-corrosion e aofia ai paipa lilivau, saʻo paipa suʻisuʻi, seamless paipa, ma isi i Saina, o loʻo faʻaaogaina lautele i laina faʻainisinia fanua e pei ole felauaiga vai mamao, suauʻu, alamanuia kemisi, kasa masani, vevela. , fa'amama otaota, punavai, alalaupapa, fausaga u'amea, felauaiga vai o le gataifale ma fa'aputuga.
