Lightweight roofs are supplied in the stainless steel grades V2A, 1.4301 (AISI 304) and V4A, 1.4404 (AISI 316L). The construction is selected to fit the diameter, static loads and openings. stainless steel lightweight roofs are used, for example, in wastewater tanks, thick sludge depots and leachate depots. Alternative roof systems are also available, such as double-membrane roofs, tarpaulin covers or special solutions.

Nozzles

For connection of the pipeline, we use nozzles with external loose flange or internal fixed flange. The surfaces in contact with the medium are made of V4A, 1.4404 (AISI 316L).
We also design and install special customer-specific solutions.

Pipeline construction

To ensure an optimal construction process, we offer our customers delivery and installation of piping construction on and in the tank during assembly.
The pipelines are designed according to customer’s desires and specifications.

Manhole / roof hatch

For inspection and maintenance work on the tank or technical installations, we recommend installing a manhole in the lower ring. In accordance with DIN EN ISO 28765, covered tanks must have a manhole DN 800. Manholes can be epoxy-coated or made of V4A stainless steel. In addition to lateral manholes, roofs can be supplied with various hatches. For gas depots, doors are also available.
