For a customer from the Netherlands Winkel Schweisstechnik delivered 2 Cartridge filters made of Duplex 1.4462 material.

The specification was very demanding, so our project manager had a lot of work during the design and manufacturing time. The filters were made to the new standard for pressure vessels, the EN 13445. However, the customer requirements concerning tests for the base materials and approvals for the welding process went far beyond those required by the standard. Several interim inspections were carried out by independent expediters. Thanks to the efforts of all departments the customer was very happy with the delivered filters. Discussions on further deliveries of duplex materials are currently underway.
