About Us

Dijkgraaf Support was founded by Peter Dijkgraaf in 2013. After initial specialisation in European standard EN 1591-4 and certification by TQ Cert as a European accredited training centre in accordance with EN 1591-4, Dijkgraaf Support began flange training. This in turn led to flange consultancy and flange competency testing in flange management.
