Ukudayiswa Okushisayo Ipayipi Elikhulu Lokunqanda ukugqwala Kwezokuthutha Eziwuketshezi
Njengamanje, ukulahlekelwa kwaminyaka yonke emhlabeni jikelele ngenxa yokugqwala kwamapayipi ensimbi kuphezulu ngendlela efinyelela kumabhiliyoni angama-500 wamadola aseMelika.Amapayipi ensimbi e-anticorrosive angakwazi ukuvimbela noma ukunciphisa ukugqwala ngokuphumelelayo, andise impilo yesevisi yamapayipi ensimbi, futhi anciphise izindleko zokusebenza zamapayipi ensimbi.
Ukwahlukaniswa: ukuhlukaniswa kwe-anti-corrosion kwangaphakathi (i-epoxy ewuketshezi yokugqoka i-IPN8710 anti-corrosion, i-fused epoxy powder anti-corrosion);ukuhlukaniswa kodonga lwangaphandle lwe-anti-corrosion, i-2PE/3PE anti-corrosion kanye ne-pe anti-corrosion yongqimba olulodwa;i-epoxy coal tar anti-corrosion;i-outer coating anti-corrosion;inqubo anti-corrosion.
Material: Ukuqaliswa kwe-FBE epoxy powder anti-corrosion SY/T0315-2005 "Ukucaciswa Kwezobuchwepheshe Kwe-Single-layer Fusion Bonded Epoxy Powder Coating for Steel Pipelines"
2PE/3PE ukuqaliswa kokunqanda ukugqwala kwe-GB/T23257-2009 "Izinga Lobuchwepheshe Le-Polyethylene yangaphandle Coating for Buried Steel Pipeline"
Izinga lokugqwala kwe-anti-corrosion surface: ukuqhuma kwesihlabathi nokususwa kokugqwala kwendawo yangaphandle yepayipi lensimbi kufinyelela ezingeni le-Sa2 1/2 ngokuya ngezidingo ze-GB/T8923-2008, kanye nokujula kwephethini lehange ebusweni bensimbi. ipayipi 40-100μm.
Ukucaciswa: ipayipi lensimbi engenamthungo, ipayipi lensimbi elivunguzayo, ipayipi elihlanganisiwe eliqondile, ipayipi lensimbi elinamandla, ipayipi lensimbi engagqwali, futhi ububanzi balo obungaphandle buyi-16-800mm
I-anti-corrosion steel pipe base base material ihlanganisa ipayipi elivunguzayo, ipayipi lomthungo eliqondile, ipayipi elingenamthungo, njll. Isetshenziswa kakhulu kwezokuthutha ngamanzi amabanga amade, uphethiloli, imboni yamakhemikhali, igesi yemvelo, ukushisa, ukuthuthwa kwendle, umthombo wamanzi, ibhuloho, insimbi. isakhiwo, ukuthuthwa kwamanzi olwandle ezweni lethu.Izinkambu zobunjiniyela bamapayipi ezifana nokunqwabelanisa.
Ngaphezu kokuthuthukisa impilo yesevisi yamapayipi ensimbi ngokusebenzisa i-anti-corrosion, kubonakala futhi kulezi zici ezilandelayo:
1. Hlanganisa amandla omshini wepayipi lensimbi nokumelana nokugqwala kwepulasitiki;
2. Udonga lwangaphandle lungaphezu kuka-2.5mm, lumelana nemihuzuko namaqhubu;
3. I-coefficient ye-friction yangaphakathi yodonga incane, i-0.0081-0.091, enciphisa ukusetshenziswa kwamandla;
4. Udonga lwangaphakathi luhlangabezana nezindinganiso zezempilo zikazwelonke;
5. Udonga lwangaphakathi lubushelelezi, akulula ukulukala, futhi lunomsebenzi wokuzihlanza
