COATED PIB
Cov kav dej yuav raug coated sab nraud kom tiv thaiv corrosion, yaig thiab ua rau muaj kev ntxhov siab. Cov yeeb nkab txheej yog siv los ntawm cov khoom siv hlau, lossis cov hlau tsis yog hlau, cov khoom siv rau sab nraud ntawm cov yeeb nkab (xws li seamless lossis welded). Cov yeeb nkab sab nraud yog siv los tiv thaiv cov hlau los ntawm qhov chaw corrosive (3LPE coated kav yog qhov kev xaiv tshaj plaws).
Feem ntau cov Coat Pipes Externally Materials:
Cov yeeb nkab tsis yog xim hlau: Cov xim, cov kua roj vanish, lacquers, bituminous coatings, resins, plasticizers, Greases, waxes, oils, Plastics (polyurethane, polyethylene, Rilsan, PTFE, PVC), Elastomers (ntau hom), Vitreous enamel, Cement mortar
Organometallic yeeb nkab txheej: Cov xim pigmented nrog hlau nyob rau hauv hmoov daim ntawv (txhuas, zinc, lead, stainless hlau), Cov xim muaj zinc ethyl-silicate
Kev hloov kho tshuaj: Phosphating, Chromatin, phosphating, Dub xov, thiab xim av
Cementation (physiochemical hloov kho)
3 LPE coated kav
3LPE coated kav muaj peb txheej polyethylene txheej uas muaj xws li:
Kev ua haujlwm siab fusion bonded epoxy (FBE),
ib copolymer nplaum
ib txheej txheej ntawm polyethylene uas muab tawv, ruaj tiv thaiv corrosion thiab yaig.
3LPE yeeb nkab haum nruab nrab mus rau siab ua haujlwm kub.
Yeeb Nkab Txheej Cov Khoom Siv thiab Qhov Zoo / Qhov Tsis Zoo:
| Yeeb Nkab Txheej Hom | Qhov zoo | Qhov tsis zoo |
| Peb txheej Polyethylene (3LPE) thiab 3 txheej Polypropylene (3LPP) | Cov khoom siv tsawg thiab cov nqi siv |
Kev siv cov nplaim taws hauv cov kav dej ib puag ncig tau ib txwm ua rau qhov chaw ua haujlwm hluav taws kub thiab tawg Yuav tsum tau siv cov nplaim taws los tsim adhesion Tsawg kub tsis kam. Qhov siab tshaj 225 ° F txog 250 ° F. Txwv qhov ntev stability Nta tsuas yog ciam teb hardness Qhia tsis zoo rau leej faj, amines, oxygen, thiab lwm yam oxidants. |
| Polypropylene (PUR) | Pom zoo rau kev siv dej hiav txwv tob nrog qhov kub thiab txias | Polypropylene yog lub luag hauj lwm rau saw degradation los ntawm raug tshav kub thiab UV hluav taws xob xws li uas muaj nyob rau hauv tshav ntuj. |
| Fusion Bonded Epoxy (FBE) | Cov tshuaj tiv thaiv zoo heev thiab kev ruaj ntseg zoo nrog kev txo qis hysteresis |
Ther kim daim ntawv thov nqi ib 'meter' FBE cov ntaub ntawv yog kim Cov yeeb nkab thiab cov ntaub ntawv txheej yuav tsum tau rhaub kom txog li 250 degree F Lub sijhawm ua haujlwm ntev |
| Asphalt enameled thiab polyurethane (PUR) | Pheej yig thiab superior rau thee enamelReduces hysteresis Kev kho mob sai |
Yooj yim tsis kam mus rau tshuaj aggression Kev ntsuas kub nruj Txwv qhov ntev stability |
HT PIPE yog cov chaw tsim khoom ntawm cov hlau tsis muaj steel, cov hlau tsis muaj steel, thiab cov khoom siv nickel alloy. Yog tias koj muaj kev xav tau txog carbon steel, nickel alloy,stainless hlau kav, steel daim hlau, puag ncig tuav, yeeb nkab fittings, thiab flanges, tiv tauj peb rau cov ntaub ntawv dawb!
