English to Russian Tech/Engineering Petroleum Eng/Sci wet sour gas pipeline

Контекст:
The delivery of the water is the result of the fluid flow inside the pipeline. Flow patterns can create conditions conducive to corrosion initiation and growth. Flow patterns can also lead to conditions where corrosion reduction due to formation of a protective scale or an oil film is very significant. In a wet sour system, it is not unusual for a pipeline to suffer severe corrosion, up to 50 mm/y, when the flow regime switches to stratified or slug flow from wave or annular mist (practically no corrosion) due to production decline.

Ну и заодно "stratified or slug flow"
Я перевел (из Мультитрана) "расслоенный и снарядный режимы потока".
Может у кого-нибудь есть first-hand knowledge - правильно ли это?!
