Dawb qauv rau Tuam Tshoj ASTM A53 / BS1387 Threaded thiab Coupled Kub Dipped Galvanized Steel Yeeb Nkab
Txheej txheem cej luam
Txhua tus tswv cuab los ntawm peb cov neeg ua haujlwm tau txais txiaj ntsig loj ua rau muaj txiaj ntsig rau cov neeg siv khoom xav tau thiab koom haum sib txuas lus rau ASTM A53 / BS1387 Kub Dipped Galvanized Steel Pipe. Vam tias peb tuaj yeem yog koj tus neeg muag khoom ntseeg siab hauv Suav teb. Nrhiav rau pem hauv ntej rau koj txoj kev koom tes .Nrog ntau tshaj 9 xyoo ntawm kev paub thiab ib pab neeg ua haujlwm, peb tau xa peb cov khoom mus rau ntau lub teb chaws thiab cheeb tsam thoob plaws ntiaj teb. Peb zoo siab tos txais cov neeg siv khoom, cov koom haum ua lag luam thiab cov phooj ywg los ntawm txhua qhov chaw hauv ntiaj teb los tiv tauj peb thiab nrhiav kev koom tes rau kev sib nrig sib pab.
Kub-dip galvanizing muaj qhov zoo ntawm txheej txheej, muaj zog adhesion thiab lub neej ua haujlwm ntev. Cov teeb meem ntawm lub cev thiab tshuaj lom neeg tshwm sim ntawm cov yeeb nkab steel matrix thiab molten plating tov los tsim cov txheej txheem corrosion-resistant zinc-hlau alloy nrog cov qauv compact. Cov txheej txheej alloy yog kev sib xyaw nrog cov zinc txheej ntshiab thiab cov yeeb nkab steel matrix. Yog li ntawd, nws cov corrosion kuj muaj zog.
Yuav tsum nco ntsoov tias xyoo 1960 thiab 1970, cov teb chaws tsim kho hauv ntiaj teb tau pib tsim cov kav dej tshiab thiab maj mam txwv cov kav dej galvanized. Plaub lub tuam tsev haujlwm thiab cov thawj coj suav nrog Ministry of Construction ntawm Tuam Tshoj kuj tau tshaj tawm cov ntaub ntawv qhia meej tias cov kav dej galvanized tau raug txwv los ntawm 2000 mus txog rau. Cov kav dej galvanized tsis tshua siv rau cov kav dej txias hauv cov zej zog tshiab, thiab cov kav dej galvanized yog siv rau cov kav dej kub hauv qee cov zej zog.
Daim ntawv thov
Nws yog siv rau kev quab yuam thiab qhov siab, thiab rau lub hom phiaj dav dav, dej, roj thiab cov kav dej.
