Double-membrane roof

Double-membrane roofs consist of an outer foil for weather protection and an inner foil for gas storage. The weather protection foil, which protects the gas storage membrane against weather effects, has its form maintained by a supporting air blower. The belt substructure prevents the gas depot from being submerged in the substrate. Operating pressures of up to 20 mbar are possible depending on the film quality, and the various configurations of the membrane facilitate high storage volumes.

Sight glass

Lateral sight glasses allow visual inspection of the surface of the medium. Lateral sight glasses are supplied as double sight glasses with water connection. Sight glasses may optionally be equipped with a wiper, external lamp or camera.

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. 

Hydraulic pressure protection

We build our DEKRA-approved overpressure and underpressure protection systems for a wide variety of installation sites. These can be integrated – so as to be impervious to frost – or externally mounted on the tank. An externally positioned design is also possible. The response pressure, maximum pressure and maximum volume flow are considered according to your requirements; the pressure protection is designed and built accordingly. On request, we can examine the system on our test bench and prepare a corresponding report. We can also carry out an individual acceptance test in cooperation with DEKRA.

Tank jacket staircase

With a tank jacket staircase, various operating points on your tank can be easily reached. The standard material is hot-dip galvanised steel; on request, however, stainless steel versions are also available. We supply winding staircase in widths of 800 mm and 1,000 mm. Alternative access options such as ladders, spiral staircases or staircase towers are available. 

Platform

We offer walkways in various designs. Polygonal walkways on the jacket or straight/sloping roof walkways are designed in accordance with EN 14122. We use standard widths of 800 mm or 1,000 mm. Walkways and platforms have gratings according to R12. They are connected to the tank wall via the substructure.

Jacket and roof insulation

We supply jacket and roof insulation in different insulation thicknesses and with steel or aluminium trapezoidal sheet metal. The roofs are clad with smooth sheet metal. Trapezoidal sheet manufacturers offer a wide choice of standard colours. Special colours can be achieved through powder coating, for example. The manhole is fitted with a removable manhole cap as standard.

We offer submersible agitators in various performance classes up to 22 KW.
Sinking and floating layers are stirred quickly and thoroughly.
The unit operates in a submerged setting and thus produces only a low-level of emissions.
