Design

• Construction codes EN13445, ASME VIII div1, AD2000, Codap, BS5500
• Statical calculations (Microprotol)
• Complementary calculations : finite elements, wind, earthquake, cyclic stress...

Fabrication

• Thicknesses from 5 mm to 50 mm
• All grades of carbon steel, stainless steel including duplex and super duplex, nickel alloys (excl. Titanium), and cladding
• Internals : grids, trays, demisters, distributors...
