Cov ntawv thov feem ntau suav nrog - siab reactors, boilers, heat exchangers, LNG cia tanks, thiab separators. Nws yog qhov zoo tagnrho rau cov roj, roj, thiab cov chaw petrochemical uas yuav tsum muaj kev ua haujlwm siab thiab qis - qhov kub thiab txias.
Dab tsi vuam consumables pom zoo rau P690QL1?
Tsawg- hydrogen vuam consumables uas txuam los yog me ntsis undermatching zog yog feem ntau pom zoo. Consumables yuav tsum muaj kev cuam tshuam zoo toughness ntawm qis kub kom phim cov khoom siv hauv paus. Kev xaiv yog nyob ntawm cov txheej txheem vuam, kev sib koom ua ke, thiab cov qauv ntawm cov hlab ntsha uas siv tau.
P690QL1 puas tuaj yeem siv rau kev qaug zog- khoom siv siab?
Yog lawm, P690QL1 tuaj yeem siv rau kev qaug zog -loaded applications thaum tsim kom raug. Siab zog thiab toughness pab tiv thaiv tawg pib. Txawm li cas los xij, weld zoo, kev sib koom ua ke, thiab kev tswj hwm kev ntxhov siab yog qhov tseem ceeb rau kev ua tiav kev ua haujlwm qaug zog.
Dab tsi yog cov ntawv thov tseem ceeb ntawm P690QL1?
P690QL1 feem ntau yog siv rau hauv cov hlab ntsha siab, boilers, kub exchangers, reactors, thiab cia tso tsheb hlau luam ua hauj lwm nyob rau hauv siab siab thiab qis - kub. Nws lub zog siab thiab zoo heev toughness ua rau nws haum rau lub zog, tshuaj lom neeg, petrochemical, thiab roj kev lag luam uas muaj kev nyab xeeb thiab kev ntseeg siab yog qhov tseem ceeb.
