Roj Hmab Lined Steel Pipes
Cov roj hmab lined steel kav yog tsim los siv nyob rau hauv ntau yam abrasive siv siv.Cov ntawv thov xws li zeb tawm, cov twj tso kua mis siab, cov kab tailings ntev, xav tau slurry twj tso kua mis thiab cov kav dej nqus.Txhua kawg nrog vulcanized roj hmab foob tsau flange.
Hnav-resistant thiab corrosion-resistant roj hmab lined steel yeeb nkab yog ua los ntawm cov yeeb nkab steel raws li cov khoom siv thiab siv nrog cov khoom zoo heev ntawm hnav-resistant, corrosion-resistant thiab kub-resistant roj hmab li hauv ob sab phlu.Nws yog compounded los ntawm cov cuab yeej tshwj xeeb nrog cov nplaum ua haujlwm siab.Feem ntau siv hauv metallurgy, hluav taws xob fais fab, tshuaj lom neeg kev lag luam, roj av, thee, cement thiab lwm qhov chaw lag luam.Hauv kev ua haujlwm mining, nws tau siv dav hauv mine tailings conveying system, thee mine backfilling thiab lwm yam yeeb nkab system teb.Tshwj xeeb, cov raj xa dej yog qhov tsim nyog rau kev xa tawm qhov kub ntawm -50 ° C rau + 150 ° C nruab nrab, uas yooj yim hnav thiab corrosion.Peb tuaj yeem ua kom cov phab ntsa tuab ntawm cov yeeb nkab ces kaum raws li cov neeg siv khoom xav tau, yog li ncua kev pab cuam lub neej.Lub caij no, lub neej kev pab cuam ntawm cov roj hmab-lined steel yeeb nkab tuaj yeem ncav cuag 15-40 xyoo.Cov yeeb nkab tuaj yeem tig tau ze li ntawm 90 degrees tom qab 6-8 xyoo ua haujlwm.Txhua lub sij hawm ntawm kev sib hloov tuaj yeem ua rau lub neej ua haujlwm ntev, Cov yeeb nkab steel tuaj yeem txuas ntxiv nrog roj hmab rau peb mus rau plaub zaug, yog li nws txo qis kev siv cov nqi ntxiv.
