PHE has been performed pressure-leak test before taking for operation.
In case of hydrostatic test, Pressurize hot and cold side independently and/or both sides at the same time.
Actual test pressure shall not exceed the specified test pressure.
Over test pressure could result in heat transfer plate/frame deformation and/or leaking.
The test pressure is referred to Plate Arrangement Drawing.
