SAND-BLASTING/PAINTING:

Alfa Engineering has gained experience in internal and external painting cycles according to the type of service and to the installation of the joints according to the specs.

We use the products of the main world-wide paint producers.

We paint our joints by following the specs. of the project and if customers needed advice on the choice of the most suitable product, we are also backed by experts who support us from a technical point of view.

TESTS

Our new testing area was designed in order to grant maximum efficiency and safety for our staff and for visitors such as inspectors and customers.
From a point outside the testing area, in a safe zone, the testing operations get started. Inside the testing area there are cameras that allow to remotely watch the tests from the inspectors’ room.

PACKING AND SHIPPING

We pack our joints in wooden crates which are fumigated according to international standards.
The joints inside the crates are packed and protected to be even seaworthy.
