Working according to a test and inspection plan is a standard and established method at GPI. Before production begins, our engineering department determines all tests and inspections required under the construction standard, and supplements them with any tests required by the client.

Our quality department carries out checks and subtests during the production process. Both the client and our quality department are present at the final acquisition.

GPI has the systems and equipment to carry out riboflavin tests, roughness tests and pressure tests. Our clients can also make use of this if so desired.

Some examples:

- Riboflavin tests

- X-rays and welding work assessments

- Welding work penetration tests

- Visual welding inspections

- Drain tests

- Pressure tests/ full of water tests

- Roughness tests

- Vacuum box texts

- Thickness tests
