Cov khoom siv xaiv ntawm sab nraud siab nthuav dav cov txheej txheem txheej txheem txheej txheem txheej txheem txheej txheem txheej txheem txheej txheem txheej txheem txheej txheem txheej txheem txheej txheem txheej txheem qub yuav tsum txiav txim siab ntau yam, cov hauv qab no yog qee cov ntaub ntawv:
Cov Hlau Hlau
Cov hlau cov hlau yog cov khoom siv feem ntau, xws li Q235 carbon hlau. Nws muaj lub zog siab thiab tawv tawv, thiab tus nqi yog tsawg. Nws tuaj yeem muab kev tiv thaiv zoo kom muaj kev tiv thaiv zoo rau kev nthuav dav thiab tiv thaiv qee yam kev ntxhov siab sab nraud. Feem ntau cov twj tseem lag luam, yog tias qhov nruab nrab tsis yog corrosive thiab ntsuas kub thiab lub zog muaj zog, carbon steel sab nraud casing yog kev xaiv nyiaj txiag.
Stainless hlau
304 Stainless hlau: zoo ib yam li cov khoom siv suab, 304 stainless hlau muaj 18% chromium thiab 8% npib thiab muaj zoo corrosion tsis kam. Thaum cov raj xa hluav taws xob yog nyob rau hauv ib qho chaw muaj kev ruaj ntseg, lossis thaum cov khoom siv ntawm corrosion tau zoo tiv thaiv cov xeb thiab txuas ntxiv kev pabcuam lub neej ntawm sab nraud casing.
{-316} stainless hlau: muaj Molybdenum caij, corrosion tsis zoo dua li 304 stainless hlau. Hauv qee qhov raj hluav taws xob kaw ze rau hiav txwv thiab nrog cov tshuaj tiv thaiv kab corrosion, 316 stainless hlau sab Nruag muaj lub nruas ntawm seawater thiab tshuaj lom neeg.
Iav Reinforced Yas
Iav Reinforced Yas (FRP) yog cov fiber ntau txhawb cov yas. Nws muaj cov yam ntxwv ntawm lub teeb yuag, muaj lub zog siab thiab corrosion tsis kam. Rau qee qhov hluav taws xob nruab nrog tshwj xeeb tshuaj lom neeg corrosion, xws li cov khoom siv acid thiab alkali meding kom tsis txhob muaj tshuaj lom neeg kom tsis txhob muaj kev puas tsuaj rau sab nraud.
