ASME SA 387 GRAD 11 Classis 2

Sicut vas pressionis gradus ferri ad usum in servitio temperatura elevato, in variis industriis adhibetur et maxime efficax est, praesertim in oleo, gas et industria petrochemica, ubi liquores et vapores saepe in superioribus temperaturis reconduntur.
Superiora chromii gradus etiam optimam corrosionis et oxidationis praebent resistentiam, quae necesse est in applicationibus gas acidis. Quaeso referas ad technicas notiones nostras infra pro ASME SA387 Grade 11 Classis II.
