Construction and maintenance of piping, pressure vessels and boilers for the most part requires flanged joints. The latter are highly advantageous as they enable fast assembly and disassembly, and facilitate installation. However, inappropriate installation may entail potential joint tightness problems and consequent risks of liquid or gas leakage.

Due to the importance of such joints, the assembly personnel is expected to be appropriately trained and certified, which is governed by the European standard EN 1591-4 and by the requirements of the Pressure Equipment Directive.

The program is intended for the assembly personnel, inspectors, work supervisors and anyone who may, one way or another, handle flanged joints.
