Zogulitsa Zotentha Zazikulu Zing'onozing'ono Chitoliro Chotsutsana ndi dzimbiri cha Mayendedwe a Madzi
Pakali pano, kutayika kwapachaka kwapadziko lonse chifukwa cha kuwonongeka kwa chitoliro chachitsulo ndikwambiri kuposa madola 500 biliyoni aku US.Mapaipi achitsulo oletsa dzimbiri amatha kuletsa kapena kuchedwetsa dzimbiri, kukulitsa moyo wautumiki wa mapaipi achitsulo, komanso kuchepetsa ndalama zoyendetsera mapaipi achitsulo.
Gulu: gulu lamkati la anti-corrosion (madzimadzi otsekemera a epoxy IPN8710 anti-corrosion, fused epoxy powder anti-corrosion);khoma lakunja la anti-corrosion classification, 2PE/3PE anti-corrosion ndi single-wosanjikiza PE anti-corrosion;epoxy malasha phula odana ndi dzimbiri;❖ kuyanika akunja odana ndi dzimbiri;ndondomeko anti- dzimbiri.
Zida: FBE epoxy powder anti-corrosion kukhazikitsa SY/T0315-2005 "Technical Specification for Single-layer Fusion Bonded Epoxy Powder Powder for Steel Pipelines"
2PE/3PE anti-corrosion kukhazikitsa GB/T23257-2009 "Technical Standard for Polyethylene External Coating for Buried Steel Pipeline"
Anti-corrosion pamwamba dzimbiri kuchotsa muyezo: sandblasting ndi dzimbiri kuchotsa pamwamba pa chitoliro zitsulo kufika Sa2 1/2 mlingo malinga ndi zofunika za GB/T8923-2008, ndi kuya kwa nangula chitsanzo pamwamba pa zitsulo. chitoliro ndi 40-100μm.
Kufotokozera: Chitoliro chachitsulo chosasunthika, chitoliro chachitsulo chozungulira, chitoliro chowongoka chowongoka, chitoliro chachitsulo chosapanga dzimbiri, chitoliro chachitsulo chosapanga dzimbiri, ndipo m'mimba mwake akunja ndi 16-800mm.
Anti-corrosion zitsulo chitoliro m'munsi zinthu zikuphatikizapo ozungulira chitoliro, chitoliro molunjika msoko, chitoliro chosanja, etc. Amagwiritsidwa ntchito mtunda wautali zoyendera madzi, mafuta, makampani mankhwala, gasi, kutentha, zimbudzi mankhwala, gwero la madzi, mlatho, zitsulo. kapangidwe, kayendedwe ka madzi am'nyanja m'dziko lathu.Mipaipi ya engineering ya mapaipi monga mulung.
Kuphatikiza pa kuwongolera moyo wautumiki wa mapaipi achitsulo kudzera mu anti-corrosion, zimawonekeranso pazinthu izi:
1. Phatikizani mphamvu zamakina za chitoliro chachitsulo ndi kukana kwa dzimbiri kwa pulasitiki;
2. Kupaka khoma lakunja ndikoposa 2.5mm, kugonjetsedwa ndi zokopa ndi tokhala;
3. Mkangano wamkati wa khoma lamkati ndi wochepa, 0.0081-0.091, womwe umachepetsa kugwiritsa ntchito mphamvu;
4. Khoma lamkati limakwaniritsa miyezo yaumoyo ya dziko;
5. Khoma lamkati ndi losalala, losavuta kukulitsa, ndipo lili ndi ntchito yodziyeretsa
