Chitoliro cha insulated ndi chitoliro cha mapaipi okhala ndi kutchinjiriza kwamafuta. Ntchito yake yayikulu ndikuchepetsa kutayika kwa kutentha panthawi yonyamula media (monga madzi otentha, nthunzi, ndi mafuta otentha) mkati mwa chitoliro ndikuteteza chitoliro kuzinthu zachilengedwe. Amagwiritsidwa ntchito kwambiri pomanga zotenthetsera, kutentha kwachigawo, mafuta a petrochemicals, engineering engineering, ndi zina.
1. Mapangidwe Apakati
Chitoliro cha insulated nthawi zambiri chimakhala chopangidwa ndi zigawo zambiri zokhala ndi zigawo zitatu zazikulu:
• Chitoliro chachitsulo chogwira ntchito: Chipinda chamkati chamkati, chomwe chili ndi udindo woyendetsa zofalitsa. Zida nthawi zambiri zimakhala ndi chitsulo chosasokoneka, zitsulo zotayirira, kapena mapaipi apulasitiki, ndipo ziyenera kukhala zosagwirizana ndi kupsinjika komanso zosachita dzimbiri.
• Insulation Layer: Chigawo chovuta kwambiri chapakati, chomwe chimateteza kutentha. Zida zodziwika bwino zimaphatikizapo thovu la polyurethane, ubweya wa miyala, ubweya wagalasi, ndi polyethylene. Chithovu cha polyurethane pakadali pano ndichosankha chodziwika bwino chifukwa cha kutsika kwake kwamafuta komanso ntchito yabwino yotchinjiriza.
• M'chimake Wakunja: Chotchinga chakunja chimateteza chinyontho, kukalamba, ndi kuwonongeka kwa makina. Zida nthawi zambiri zimakhala ndi polyethylene yapamwamba kwambiri (HDPE), fiberglass, kapena anti-corrosion coating.
II. Mitundu Yaikulu ndi Makhalidwe
Kutengera ndi zinthu zotchinjiriza komanso mawonekedwe ogwiritsira ntchito, mitundu yodziwika bwino ndi mawonekedwe ndi awa:
• Polyurethane Insulated Pipe: Thermal conductivity ≤ 0.024 W / (m·K), kutsekemera kwapamwamba kwambiri, kutsika kwa kutentha, komanso kukalamba. Yoyenera pamapaipi amadzi otentha ndi nthunzi omwe ali ndi kutentha kwapakati pa -50 ° C ndi 120 ° C, ndiye njira yabwino yopangira zotenthetsera zapakati ndi pansi.
• Rockwool Insulated Pipe: Kutentha kwapamwamba (mpaka 600 ° C) ndi kutentha kwamoto (Kalasi A yosayaka), koma ndi kuyamwa kwa madzi, kumafuna chinyezi. Amagwiritsidwa ntchito kwambiri pamapaipi omwe amatentha kwambiri m'mafakitale (monga mapaipi a nthunzi ya boiler).
• Chitoliro cha Ubweya Wagalasi: Chitoliro chopepuka, chokhala ndi zotsekereza mawu momveka bwino, komanso kukana kutentha kwa -120°C mpaka 400°C, ndi yoyenera ku mapaipi osatentha kwambiri (monga mapaipi a refrigerant air conditioning) ndi kutsekereza mapaipi m’nyumba za anthu.
III. Ubwino Wachikulu
1. Kupulumutsa Mphamvu ndi Kuchepetsa Kugwiritsa Ntchito: Kumachepetsa kutentha kwapakati, kumachepetsa kugwiritsa ntchito mphamvu pakutentha, kupanga mafakitale, ndi zochitika zina. Kugwiritsa ntchito nthawi yayitali kumatha kuchepetsa kwambiri ndalama zogwirira ntchito.
2. Chitetezo cha Mapaipi: Chovala chakunja chimateteza madzi, dzimbiri, ndi makina amakina, kukulitsa moyo wautumiki wa chitoliro ndikuchepetsa pafupipafupi kukonza.
3. Ntchito Yapaipi Yokhazikika: Imasunga kutentha kwapakati kuti zisasinthe kusintha kwa kutentha kuti zisakhudze ntchito (mwachitsanzo, kusunga kutentha kwa m'nyumba kwa mapaipi otenthetsera ndikuwonetsetsa kuti mapaipi a mafakitale akhazikika).
4. Kuyika Kwabwino: Mapaipi ena opangidwa ndi insulated ndi opangidwa kale, omwe amangofuna kulumikizidwa ndi kukhazikitsa pamalowo, kufupikitsa nthawi yomanga ndikuchepetsa zovuta.
IV. Kugwiritsa Ntchito
• Municipal: Malo otenthetsera magetsi apakati m'tauni ndi mapaipi amadzi apampopi (kuteteza kuzizira m'nyengo yozizira).
• Kumanga: Mapaipi otenthetsera pansi m'nyumba zogona ndi zamalonda, ndi mapaipi apakati otenthetsera ndi kuzizirira apakati pa mpweya.
• Mafakitale: Mapaipi amafuta otentha m'mafakitale a petroleum ndi mankhwala, mapaipi a nthunzi m'mafakitale opangira magetsi, ndi mapaipi apakati a cryogenic mumayendedwe ozizira.
