Thaum nws los txog rau kev xaiv cov khoom siv zoo rau cov kav dej, cov pa roj carbon steel thiab cov kav hlau dub yog cov feem ntau siv hauv kev lag luam thiab kev tsim kho. Thaum ob qho tib si yog tsim los ntawm cov hlau zoo sib xws, lawv cov khoom, kev siv, thiab cov yam ntxwv sib txawv. Kab lus no delves rau hauv plaub qhov sib txawv ntawm cov pa roj carbon steel piping thiab dub steel piping, tshawb txog lawv cov kev siv, muaj pes tsawg leeg, lub zog, thiab kev saib xyuas. Peb tseem yuav muab lub rooj sib piv los pab koj nkag siab zoo dua qhov sib txawv no.
1. Cov khoom sib xyaw thiab txheej txheej
Ib qho ntawm qhov sib txawv tshaj plaws ntawm cov pa roj carbon steel piping thiab dub steel piping yog nyob rau hauv cov khoom ntawm cov khoom thiab kev kho deg.
Carbon Steel Piping
Carbon steel kav feem ntau yog tsim los ntawm hlau thiab carbon, nrog rau lwm yam xws li manganese thiab cov kab ntawm silicon. Cov ntsiab lus carbon ntawm cov kav dej no feem ntau yog li ntawm 0.05% txog 2.0%. Qhov sib txawv ntawm cov ntsiab lus carbon tuaj yeem cuam tshuam rau cov yeeb nkab lub zog, hardness, thiab yooj. Qhov siab dua cov ntsiab lus ntawm cov pa roj carbon monoxide, cov yeeb nkab muaj zog thiab nkig ntau dua, uas yog qhov tseem ceeb rau kev siv tshwj xeeb.
Dub Steel Piping
Cov yeeb nkab dub yog qhov tseem ceeb ntawm cov yeeb nkab carbon steel. Qhov sib txawv tseem ceeb nyob hauv qhov tsis muaj txheej txheej lossis galvanization. Cov kav hlau dub feem ntau siv yam tsis muaj txheej txheej tiv thaiv sab nraud, txhais tau tias lawv feem ntau npog hauv txheej txheej ntawm cov hlau oxide dub lossis tsaus nti - xim hlau oxide txheej. Qhov "dub" zoo li no los ntawm cov txheej txheem oxidation uas tshwm sim thaum lub sij hawm tsim cov yeeb nkab. Cov kav dej no tsis muaj kev tiv thaiv zinc txheej zoo li cov kav dej galvanized, uas ua rau lawv yooj yim dua rau corrosion thaum raug ya raws.
2. Lub zog thiab kav ntev
Cov pa roj carbon steel thiab cov kav dej dub yog cov kav ntev thiab siv ntau yam kev siv. Txawm li cas los xij, lawv cov khoom muaj zog sib txawv vim lawv cov khoom sib xws.
Carbon Steel Piping
Carbon steel kavmuaj nyob rau hauv ntau qib, xws li me me mus rau siab - cov ntsiab lus carbon. Lub zog ntawm cov kav dej no nce nrog cov ntsiab lus carbon, tab sis qhov no kuj ua rau lawv tsis yooj yim dua. Cov pa roj carbon me me, piv txwv li, yog cov kav dej ntau dua thiab hloov tau yooj yim, thaum siab - carbon steel kav yuav muaj zog dua tab sis nkig ntau dua. Cov yeeb nkab carbon steel muaj kev tiv thaiv zoo rau cov neeg kho tshuab kev ntxhov siab, ua rau lawv zoo tagnrho rau kev siv siab -.
Dub Steel Piping
Cov kav hlau dub, txawm hais tias yog ib feem ntawm tsev neeg carbon steel, feem ntau tsis muaj zog dua li lwm cov pa roj carbon steel kav vim tsis muaj cov txheej txheem tiv thaiv thiab cov ntsiab lus carbon tsawg hauv kev sib piv. Txawm li cas los xij, lawv tseem suav hais tias muaj zog thiab zoo -tsim nyog rau cov ntawv thov uas muaj cov txheej txheem siab tsawg -. Cov hlau dub feem ntau yog siv rau cov roj thiab cov kab dej, qhov twg lub zog yog qhov tseem ceeb tab sis huab cua tsis zoo tsis yog qhov tseem ceeb.
3. Daim ntawv thov thiab kev siv
Nkag siab txog cov ntawv thov tshwj xeeb rau txhua hom yeeb nkab yog qhov tseem ceeb thaum xaiv cov khoom siv rau koj qhov project.
Carbon Steel Piping
Cov pa roj carbon steel kav yog dav siv nyob rau hauv ntau yam lag luam, xws li petrochemical, kev tsim kho, thiab kev tsim khoom. Lawv lub zog ua rau lawv zoo tagnrho rau kev nqa siab -kua kua, roj, thiab roj. Qee qhov kev siv rau cov yeeb nkab carbon steel muaj xws li:
- Cov nroj tsuag muaj zog: Siv rau kev thauj khoom siab -siab zog.
- Petroleum kev lag luam: Zoo tagnrho rau kev thauj cov roj av thiab cov nkev.
- Kev tsim kho: Kev tsim cov kav dej thiab kev txhawb nqa rau lub tsev ua haujlwm.
- Automotive kev lag luam: Siv los ua chassis thiab tso pa tawm.

Dub Steel Piping
Cov kav hlau dub, ntawm qhov tod tes, feem ntau yog siv rau hauv cov ntawv thov uas tseem tsim nyog, tab sis tsis tas yuav muaj siab - siab ua haujlwm. Cov kav hlau dub feem ntau yog siv rau hauv cov ntawv hauv qab no:
- Gas cov kab: Feem ntau siv rau hauv kev teeb tsa ntawm cov kab hluav taws xob, vim lawv muaj zog txaus los tswj lub siab ntawm cov roj ntws.
- Hluav taws kub sprinkler systems: Cov kav dej dub yog siv rau kev txhim kho cov hluav taws kub hnyiab hauv cov tsev vim lawv qhov zoo heev tiv taus cua sov.
- Cov kab dej: Siv nyob rau hauv cov dej faib tshuab qhov twg cov kav dej tsis tas yuav tiv taus rau sab nraud corrosion.
- Cua sov tshuab: Siv rau cov tshuab uas faib cov chav dej los yog dej kub hauv chaw tsim khoom.
4. Kev tu thiab corrosion kuj
Kev saib xyuas thiab kev tiv thaiv corrosion ntawm cov pa roj carbon steel thiab cov kav hlau dub yog qhov tseem ceeb uas yuav tsum tau xav txog, tshwj xeeb tshaj yog thaum cov kav dej siv hauv qhov chaw hnyav.
Carbon Steel Piping
Thaum cov pa roj carbon steel yeeb nkab paub txog lawv lub zog, lawv kuj ua rau corrosion nyob rau lub sijhawm, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas muaj av noo, huab cua kub, los yog raug tshuaj lom neeg. Kev tiv thaiv corrosion tuaj yeem txhim kho los ntawm ntau txoj hauv kev, xws li siv cov txheej txheem (xws li, epoxy lossis enamel), galvanization, lossis siv cov hlau tsis muaj hlau. Kev tshuaj xyuas thiab kev saib xyuas tsis tu ncua yog qhov tseem ceeb los xyuas kom meej tias cov kav dej nyob hauv qhov zoo thiab tiv thaiv kev ua tsis tiav, tshwj xeeb tshaj yog nyob rau hauv siab - siab lossis qhov chaw muaj kev phom sij.
Dub Steel Piping
Cov kav hlau dub, tsis muaj coated, muaj kev tiv thaiv corrosion ntau dua li lwm hom steel kav, tshwj xeeb tshaj yog thaum raug dej. Sij hawm dhau mus, txheej txheej hlau oxide tuaj yeem ua kom tuab, ua rau cov yeeb nkab tsis zoo. Txhawm rau tiv thaiv qhov no, cov kav hlau dub feem ntau pleev xim los yog coated nrog cov tshuaj tiv thaiv -corrosive. Txawm li cas los xij, lawv feem ntau tsis haum rau kev siv sab nraum zoov tshwj tsis yog lawv tau coated kom zoo thiab tiv thaiv los ntawm ib puag ncig.
Txawm hais tias cov kev cov nyom no, cov kav hlau dub tseem yog ib qho kev xaiv nrov rau cov kab hauv av thiab dej, vim lawv yooj yim rau nruab thiab tswj, tshwj xeeb tshaj yog nyob rau hauv qhov chaw qhuav hauv tsev.
