Kev Cuam Tshuam: Yuav tsum them Charpy V-Motch cuam tshuam kev ntsuas kom ntseeg tau tias tsis kam mus rau brittle lov, tshwj xeeb tshaj yog nyob rau hauv qhov chaw tsawg-.
Tsis Yog-kev sim ua txhaum (NDT): PSL2 yuav tsum muaj NDT dav, suav nrog Ultrasonic kev sim (tr) rau cov yeeb nkab lub cev thiab txawm yog siv lossis hluav taws xob rau Weld Seam hauv Weld Seam Hauv Weld
Tus nqi: Kim kim vim kev ua si sab thiab kev xeem.
- Cov Ntawv Thov:
Cov roj muaj txiaj ntsig siab thiab roj Kev Kis Roj Pipelines.
Ntev-righpelines.
Pipelines hauv cov huab cua txias (piv txwv li, Cheeb Tsam Arctic).
Offshore thiab subsea pipelines.
Cov khoom siv tseem ceeb rau kev nyab xeeb thiab kev ntseeg tau yog qhov tseem ceeb.
General-hom phiaj Pipelines qhov kev ua tau zoo tsis yog qhov tseem ceeb.
TSEEM sib txawv ntawm PSL1 thiab PSL2
| Yam zoo | API 5L PSL1 | API 5L PSL2 |
