At Whittaker we design and manufacture vessels in carbon steel, duplex, stainless steel and aluminium. We can design to ASME VIII Division 1 and Division 2 (U & U2 Stamp), PD5500, BS EN 13445 (P.E.D. Cat I,II,III and IV under modules H & G). In addition to the manufacture of pressure vessels we are also authorised for vessel repairs on or off site under National Board ‘R’ stamp (ASME Vessels). By combining a machine shop and a fabrication shop under one roof, we can rebuild, refurbish and re-test heat exchangers and pressure vessels in a seamless cost-effective process.
