Quality Assurance

HPO certification and EN 729 / TRD 201 are a prerequisite for manufacturing tanks that are subject to acceptance tests. That includes welding and procedure qualifications, which are constantly monitored. In addition, we have a quality assurance system with a supervised manual that has been reviewed and evaluated by a notified body according to the requirements of Appendix III Module D & D1 of the Pressure Equipment Directive 2014/68/EU.

A few planning steps are required before we start the manufacturing process. These include:

  • Designing the components using modern calculation programs
  • Creating drawings with up-to-date CAD systems
  • Compiling parts lists
  • Creating internal and external testing steps
  • Preliminary tests by the inspection company
  • Choosing the suppliers
