Cov khoom tseem ceeb ntawm lub tshuab capping, xws li cov ncej thiab cov kab ke sib kis, feem ntau yog ua los ntawm cov hlau los xyuas kom cov khoom ruaj khov thiab kav ntev. Cov khoom siv hlau muaj xws li stainless hlau, aluminium alloy, thiab carbon hlau.
* Stainless hlau: dav siv nyob rau hauv cov khoom noj thiab tshuaj industries vim nws zoo heev corrosion kuj. Nws tuaj yeem tiv taus qhov chaw ua haujlwm hnyav thiab ua kom cov khoom huv thiab nyab xeeb.
* Aluminium alloy: Lub teeb yuag thiab nrawm- tso dej tawm, ua rau nws tsim tshwj xeeb rau siab -ceev capping tshuab. Cov khoom siv aluminium alloy zoo txo qhov hnyav tag nrho ntawm cov cuab yeej, txhim kho kev ua haujlwm zoo, thiab sai sai dissipate tshav kub generated thaum lub sij hawm ua hauj lwm, ncua cov cuab yeej lifespan.
* Cov pa roj carbon steel: tus nqi qis, tsim nyog rau kev siv dav dav. Cov khoom siv carbon steel txo cov nqi tsim khoom thaum ua kom muaj zog txaus, ua rau cov tshuab capping raug nqi ntau dua - zoo.
