Hauv kev tsim khoom lag luam, cov kav dej zoo li "cov hlab ntsha" uas txuas ntxiv thauj cov khoom xws li ore slurry, thee hmoov, thiab cov khoom pov tseg. Txawm li cas los xij, feem ntau ntawm cov ntaub ntawv no muaj cov yam ntxwv ntawm siab hardness thiab nrawm nrawm. Cov kav dej zoo ib yam yuav sai sai no nrog cov xau, uas tsis tsuas yog yuav tsum tau kaw thiab hloov pauv ntau zaus, tab sis kuj tseem tuaj yeem ua rau muaj kev nyab xeeb vim cov khoom xau. Qhov tshwm sim ntawm silicon carbide coj-resistant pipelines yog precisely los daws qhov "hnav teeb meem".
Qee tus neeg yuav nug, yam khoom siv yog "silicon carbide"? Qhov tseeb, nws tsis yog qhov tshiab. Qhov tseem ceeb, nws yog ib qho khoom siv tsis muaj hlau tsis muaj hlau uas muaj cov khoom siv silicon thiab cov pa roj carbon monoxide, nrog lub hardness thib ob tsuas yog pob zeb diamond thiab corundum. Ntau cov ntawv xov xwm siab kawg thiab cov cuab yeej sib tsoo feem ntau siv hauv lub neej niaj hnub siv silicon carbide. Thaum cov khoom siv siab tawv no tau ua rau hauv cov phab ntsa sab hauv ntawm lub raj xa dej, nws zoo li muab ib txheej ntawm "pob zeb diamond armor" rau hauv cov raj xa dej. Thaum ntsib cov khoom siv siab hnav, nws tuaj yeem tiv taus qhov cuam tshuam thiab kev sib txhuam ntawm cov ntaub ntawv, ua kom lub neej ntev ntawm cov kav dej.
Piv nrog rau cov kav dej ib txwm muaj, qhov zoo ntawm silicon carbide hnav-resistant pipelines mus dhau "hnav tsis kam". Cov kav hlau zoo tib yam tau yooj yim corroded los ntawm cov ntaub ntawv corrosive thaum lub sij hawm thauj mus los, thiab cov kav dej yas yog qhov nyuaj rau kev tiv thaiv qhov kub thiab txias. Txawm li cas los xij, cov ntaub ntawv silicon carbide lawv tus kheej muaj cov yam ntxwv ntawm cov kua qaub thiab alkali tsis kam thiab kub tsis kam. Txawm hais tias thauj cov kua qaub slurry los yog kub-kub cov hmoov hmoov, lawv tuaj yeem ua haujlwm ruaj khov yam tsis muaj kev txhawj xeeb txog "corrosion perforation" lossis "high-temperature deformation". Qhov tseem ceeb tshaj, nws cov phab ntsa sab hauv yog du, ua rau nws tsis tshua muaj kev cuam tshuam thiab txhaws thaum lub sij hawm thauj khoom, txo qhov hassle ntawm kev tu cov kav dej thiab ua kom cov khoom txuas ntxiv.
Niaj hnub no, nyob rau hauv kev lag luam xws li mining, hluav taws xob, thiab tshuaj engineering uas yuav tsum tau heev hnav tsis kam rau pipelines, silicon carbide coj-resistant pipelines tau maj mam hloov ib txwm pipelines. Nws tsis tas yuav hloov txhua rau lub hlis ib yam li cov kav dej zoo tib yam, thiab tsis tas yuav tsum tau them nqi kho dua. Txawm hais tias thawj zaug peev yuav zoo li me ntsis siab dua, nws ua tau pab lub lag luam txuag nyiaj ntau hauv lub sijhawm ntev. Rau cov lag luam nrhiav kev ua haujlwm tau zoo thiab ruaj khov, xaiv cov kav dej silicon carbide hnav-tiv taus yog qhov tseeb xaiv "kev txhawj xeeb tsawg dua, ntev-ntev" kev thauj mus los.
Nrog rau qhov kev thov ntau ntxiv rau cov cuab yeej siv tau ntev thiab kev nyab xeeb hauv kev tsim khoom, daim ntawv thov scenarios ntawm silicon carbide hnav-resistant pipelines yog tas li nthuav. Nws daws qhov teeb meem "laus thiab nyuaj" hauv kev thauj mus los hauv kev lag luam nrog kev ua haujlwm nyuaj ntawm cov khoom siv nws tus kheej, thiab tseem muab ntau lub lag luam nrog kev xaiv txhim khu kev qha ntawm txoj kev kom txo nqi thiab txhim kho kev ua haujlwm.
