Finishes are directly related to the material stored, these can be only weld cleaning, weld bead removal or as specialized for the food or pharmaceutical industry with a roughness finish of Ra= 1.6µm to 0.8 µm.

As part of the quality assurance of welded joints, they are inspected by ASNT certified personnel in the following non-destructive tests:

Visual Inspection Level II (VT)

Liquid Penetrant Level II (PT)

Industrial Ultrasonic Level II (UT)

Level II X-Ray Testing (RT)
