Nrog rau txoj kev loj hlob ntawm kev lag luam niaj hnub no, qhov kev thov rau high-temperature thiab high-pressure resistant hlau hose kuj nce. Cov hlau hose yog qhov tseem ceeb ntawm cov kabmob uas tau muab tso rau hauv lub raj xa dej siab, thiab ua lub luag haujlwm ntawm cov sheath rau kev sib kis ntawm cov kua thiab kab tib lub sijhawm. Hlau hose yog ib qho tseem ceeb hauv kev lag luam niaj hnub no. Hlau hose yog siv los ua hlau, cable, xaim thiab cable tu Tube rau kev siv lub teeb pom kev zoo thiab cov kav dej hauv dej. Nrog rau kev vam meej ntawm niaj hnub haiv neeg thiab kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis, cov khoom no tau raug coj los siv hauv peb lub neej.
Raws li cov khoom tseem ceeb hauv kev lag luam niaj hnub no, hlau hose tuaj yeem siv los ua cov xaim thiab cable, pej xeem da dej hose thiab tsis siv neeg pom cov teeb liab xaim thiab cable tiv thaiv yeeb nkab. Yog vim li cas vim li cas nws tuaj yeem siv rau hauv ntau qhov chaw yog sib cais los ntawm qhov zoo ntawm cov hlau hose nws tus kheej. Nws muaj yim qhov zoo hauv qab no:
1. Ua tau zoo ntawm cov hlau hose pitches.
2. Cov hlau hose muaj qhov hloov tau zoo yam tsis muaj kev cuam tshuam thiab nruj.
3. Cov hlau hose muaj lub teeb yuag thiab zoo caliber sib xws.
4. Cov hlau hose muaj qhov ua tau zoo, rov ua dua thiab hloov tau yooj yim.
5. Cov hlau hose muaj corrosion kuj zoo thiab kub ua hauj.
6. Cov hlau hose yog cov pov thawj nas thiab hnav-tiv taus, uas tuaj yeem tiv thaiv cov xov hlau sab hauv kom tsis txhob hnav.
7. Cov hlau hose muaj zog khoov tsis kam, tensile muaj nuj nqi thiab sab siab tsis kam.
8. Cov hlau hose yog mos thiab du, yooj yim rau xov thiab nrhiav cov cuab yeej.
