Kev Siv Cov Kav Hlau

Kev Siv Cov Kav Hlau
Cov kav hlau hlau yog ib hom hlau nrog cov kab hla hollow-seem, uas nws muaj ntau dua li ntawm txoj kab uas hla lossis ib ncig ntawm cov teb. Cov hauv qab no yog lub ntsiab siv ntawm cov kav hlau:

1. Kev lag luam kev tsim kho
Cov kav hlau hlau feem ntau siv hauv cov ncej, kab teeb, kab, kab ntawv thiab lwm yam ntawm kev teeb tsa tsev, thiab tuaj yeem tiv thaiv loj loj.
Hauv cov vaj tse qauv, cov kav hlau steel yog cov khoom siv tsis tau, vim yog lawv lub zog siab thiab cov seismic tsis zoo, lawv tsim nyog rau cov tsev loj thiab qhov chaw loj.
Lawv kuj tau siv nyob rau hauv Daim Ntawv Thov Tshwj Xeeb Tshwj Xeeb xws li qhob cij xa pipelines thiab cov dej ntws tawm.

2. Kev lag luam roj av
Cov khoom siv hlau steel yog cov khoom tseem ceeb hauv cov roj thiab cov pa roj pipeline tshuab, muaj kev kub siab tiv taus thiab corrosion ua thiab txias tsis kam.
Lawv kuj siv nyob rau hauv cov roj kab ke, cov kav dej roj thiab lwm cov roj teeb cov roj thiab cov roj tawm.

3. Tshuaj Kev Lag Luam
Cov kav dej steel tau siv coj los thauj ntau yam tshuaj lom neeg siv tshuaj, xws li cov kua qaub thiab alkalis, vim tias lawv cov tshuaj corrosion, kub tsis kam thiab kub tiv taus.
Lawv kuj tau siv los ua cov khoom siv tshuaj lom xws li reactors thiab distillation yees.

4. Tsheb thauj mus los
Cov neeg tiv thaiv hlau yog siv dav hauv kev tiv thaiv kev nyab xeeb, cov choj, kev sib txuas thiab lwm yam khoom muaj zog thiab muaj kev nyab xeeb.
Lawv kuj tau siv nyob rau hauv tsheb tsim khoom, aerospace thiab lwm hom teb.

5. Fais Fab Kev Lag Luam
Cov kav hlau hlau siv tau cov hlua hlau siv cov kab thiab kev hloov chaw ua cov ntaub ntawv siv tau thiab ruaj khov. Lawv muaj cov yam ntxwv ntawm kev ua ruaj khov thiab muaj zog dua li dag zog.

6. Ua liaj / teb
Cov kav dej steel yog siv rau hauv cov vaj tse ntawm cov greenhouses thiab Farration ua haujlwm, siab tsis kam, siab tsis kam thiab hnav tsis kam.

7. Kev tiv thaiv ib puag ncig
Cov khoom siv tshuaj tiv thaiv ib puag ncig xws li cov raj xa dej hluav taws xob kho cov nroj tsuag thiab cov roj fleefission roj teeb.

8. Kev tsim khoom
Cov kav dej hlau yog siv los tsim cov tshuab siv cov tshuab hluav taws xob thiab xws li cov kav dej aviation tswv yim, thiab lwm yam.

9. GOTIVE DRILLING
Cov kav dej hlau siv tau siv hauv cov cuab yeej xws li roj drilling kav thiab geological kav dej.

10. Lwm cov kev siv
Cov kav hlau hlau kuj siv los tsim cov choj loj, ntim khoom, ntsuas, thiab lwm yam, nrog cov hlau txo qis thiab txuag cov hlau.
Ntsiab lus: Cov kav dej hlau muaj ntau yam kev siv, kev tsim kho cov roj av, hluav taws xob, kev lag luam ib puag ncig, tshuab nqus khoom, geological drilling thiab lwm hom teb. Lawv yog qhov tsis tseem ceeb thiab cov khoom tseem ceeb hauv kev lag luam niaj hnub.
