Cov yeeb nkab steel-plastic composite yog ua los ntawm kub-dip galvanized steel yeeb nkab raws li lub hauv paus, thiab cov yas yog siv rau ntawm phab ntsa sab hauv (los yog sab nrauv phab ntsa yog tsim nyog) los ntawm cov hmoov yaj tshuaj tsuag tshuab, nrog kev ua tau zoo heev. Piv nrog rau cov kav dej galvanized, nws muaj qhov zoo ntawm kev tiv thaiv corrosion, tsis muaj xeb, tsis muaj fouling, du ntws, huv si thiab tsis muaj tshuaj lom, thiab lub neej ua haujlwm ntev. Raws li kev ntsuam xyuas, lub neej kev pab cuam ntawm steel-yas composite yeeb nkab yog ntau tshaj peb zaug ntawm cov yeeb nkab galvanized. Piv nrog rau cov kav dej yas, nws muaj qhov zoo ntawm cov neeg kho tshuab siab, zoo siab tsis kam thiab kub tsis kam. Txij li thaum lub hauv paus yog steel yeeb nkab, tsis muaj embrittlement lossis aging teeb meem. Nws tuaj yeem siv dav hauv kev thauj mus los thiab cov dej kub xws li cov kais dej, roj, thiab cov khoom siv tshuaj, thiab yog cov khoom siv kho dua tshiab ntawm cov kav dej galvanized. Vim tias nws txoj kev teeb tsa thiab siv cov txheej txheem yog tib yam li cov kav dej galvanized, cov yeeb nkab fittings yog tib yam, thiab nws tuaj yeem hloov cov kav dej txhuas-yas sib xyaw hauv cov kav dej loj loj, nws yog qhov nrov heev nrog cov neeg siv thiab tau dhau los ua ib qho. ntawm cov khoom tshiab uas muaj kev sib tw tshaj plaws hauv kev lag luam pipeline.
Coated steel kav yog tsim los ntawm txheej yas ntawm cov kav loj-inch kauv welded kav thiab high-frequency welded kav. Qhov siab tshaj plaws yeeb nkab txoj kab uas hla yog 1200mm. Raws li cov kev xav tau sib txawv, lawv tuaj yeem ua cov txheej txheej yas ntawm ntau yam khoom xws li polyvinyl chloride (PVC), polyethylene (PE), epoxy resin (EPOZY), thiab lwm yam. Lawv muaj qhov adhesion zoo thiab muaj zog corrosion kuj. Lawv tiv taus cov kua qaub, muaj zog alkali thiab lwm yam tshuaj corrosion. Lawv yog non-toxic, xeb-pov thawj, hnav-tiv taus, cuam tshuam-resistant thiab permeable. Cov yeeb nkab saum npoo yog du thiab tsis ua raws li cov khoom siv. Nws tuaj yeem txo qhov tsis kam ntawm kev thauj mus los, txhim kho tus nqi ntws thiab kev thauj mus los, thiab txo qis kev poob siab thaum thauj. Tsis muaj cov kuab tshuaj nyob rau hauv txheej, thiab tsis muaj cov tshuaj exudable, yog li nws yuav tsis ua paug qhov nruab nrab ntawm kev thauj mus los, yog li ua kom lub purity thiab huv si ntawm cov kua. Nws tuaj yeem siv hloov pauv hauv cov voj voog kub thiab txias hauv thaj tsam ntawm -40 degree mus rau +80 degree, thiab nws yuav tsis muaj hnub nyoog lossis tawg, yog li nws tuaj yeem siv rau hauv qhov chaw hnyav xws li qhov chaw txias.
