Subject: нефтепроводы gen. The results showed that the uniform corrosion rates of TP140 in both 120 _0C fresh acid and 170 _0C spent acid environments were within the range of the first grade of standard. The acidizing corrosion inhibitor was adsorbed on the specimens to form films which largely reduced the uniform corrosion rates of TP140 in fresh acid and spent acid environments, ff adsorbed films were imperfect during the acidification, it would result in more serious localized corrosion.Sorry! Весь текст переводить не надо. Просто никогда не встречал оборота - "first grade of standard" (2-я строка сверху). Наверно, чисто американское выражение.
Как вар. "прекрасно выдержали (коррозионные) испытания" или "в пределах стандартных значений".
Заранее, спасибо.
