Insulated pombi inonzi pombi system ine thermal insulation. Basa rayo repakati nderokudzikisa kurasikirwa kwekupisa panguva yekutakura midhiya (senge mvura inopisa, steam, uye mafuta anopisa) mukati mepombi uchidzivirira pombi kubva kune zvakatipoteredza. Inoshandiswa zvakanyanya mukuvaka kudziyisa, kupisa kwedunhu, petrochemicals, mainjiniya emagetsi, uye mamwe minda.
1. Chimiro Chikuru
Insulated pombi inowanzova yakawanda-layer composite chimiro chine zvikamu zvitatu zvikuru:
• Working Steel Pipe: Inner core layer, ine basa rekutakura nhepfenyuro. Zvishandiso zvinowanzo sanganisira simbi isina musono, galvanized simbi, kana pombi dzepurasitiki, uye zvinofanirwa kusaita kumanikidza uye kusaita ngura.
• Insulation Layer: Iyo yakakosha yepakati layer, ine mutoro wekupisa kwekushisa. Zvishandiso zvakajairika zvinosanganisira polyurethane foam, rock wool, girazi mvere, uye polyethylene. Polyurethane furo parizvino ndiyo yakasarudzika sarudzo nekuda kwekudzika kwayo kwekushisa conductivity uye yakanakisa insulation kuita.
• Outer Sheath: Rudzi rwekunze runodzivirira runodzivirira ganda rekudzivirira kubva pakunyorova, kuchembera, uye kukuvara kwemagetsi. Zvishandiso zvinowanzo sanganisira yakakwirira-density polyethylene (HDPE), fiberglass, kana anti-corrosion coating.
II. Mhando Huru uye Hunhu
Zvichienderana neyakavharirwa zvinhu uye mamiriro ekushandisa, marudzi akajairwa uye maitiro ndeaya anotevera:
• Polyurethane Insulated Pipe: Thermal conductivity ≤ 0.024 W / (m · K), kushandiswa kwepamusoro kwekudzivirira, kuderera kwekushisa, uye kuchembera kukwegura. Inokodzera mvura inopisa uye mapaipi ehutsi ane tembiricha iri pakati -50°C kusvika 120°C, isarudzo inosarurwa yekudziya yepakati uye pasi masisitimu ekudziya.
• Rockwool Insulated Pipe: Kurwisana kwepamusoro-kupisa (kusvika ku600 ° C) uye chiyero chemoto chepamusoro (Kirasi A chisingaiti), asi nekukwirira kwemvura, kunoda kunyorova. Iyo inonyanya kushandiswa kune maindasitiri epamusoro-tembiricha mapaipi (senge boiler chiutsi pombi).
• Glass Wool Insulated Pipe: Huremu, ine ruzha rwekuvharisa zvakanakisa, uye tembiricha inodzivirira kubva -120°C kusvika 400°C, inokodzera mapaipi asina kutonhora zvakanyanya (sepaipi dzefiriji yemhepo) uye pakuvharisa pombi muzvivakwa zvevagari vemo.
III. Core Zvakanakira
1. Kuchengetedza Kwemagetsi uye Kuderedza Kushandiswa: Kunoderedza kurasikirwa kwekupisa mukati, kuderedza kushandiswa kwesimba mukupisa, kugadzirwa kwemaindasitiri, uye zvimwe zviitiko. Kushandiswa kwenguva refu kunogona kuderedza zvakanyanya mari yekushandisa.
2. Pipeline Dziviriro: Iyo sheath yekunze inodzivirira kubva kumvura, ivhu corrosion, uye mechanical kukanganisa, kuwedzera hupenyu hwesevhisi yepombi uye kuderedza kuwanda kwekugadzirisa.
3. Stable Pipeline Operation: Inochengetedza yakagadzikana yepakati tembiricha kudzivirira kuchinjika kwetembiricha kubva pakukanganisa kushanda (semuenzaniso, kuchengetedza tembiricha yemukati yekudziya pombi uye kuona kugadzikana kwemaitiro epombi dzeindasitiri).
4. Kuiswa kwakareruka: Mamwe mapaipi akaiswa insulated akagadzirwa kare, anoda chete pa-saiti kubatana uye kuiswa, kupfupisa nguva yekuvaka uye kuderedza kuoma.
IV. Applicable Applications
• Municipal: Manetiweki ekudziisa mumaguta uye pombi dzemvura dzepombi (kudzivirira kutonhora kwechando munguva yechando).
• Kuvaka: Mapombi ekudziya epasi muzvivakwa zvekugara uye zvekutengesa, uye kudziyisa uye kutonhora kwepakati pombi dzepakati pemhepo.
• Indasitiri: Mapombi eoiri anopisa mumaindasitiri epetroleum nemakemikari, mapaipi anopfungaira ari mumaplanti emagetsi, uye mapaipi epakati ari mucheni anotonhora.
