Pressure Vessels – Non-Pressure Vessels - Storage Tanks – Filter Casings – Water Tanks – Food Silos – Cyclones – Discharge Silencer

Pressure Vessels

These pressure vessels are filled with activated carbon and are used to clean pollutants in sewage. Activated carbon is particularly suitable for absorbing organic substances. As an alternative, the vessels are also suitable for the treatment of turbidity filtration during beverage processing. The vessels are construed designed for a maximum operating pressure of 5 bar.

Project Information 
Material: stainless steel 1.4301
Medium: sewage, fluid group 2
Wall thickness: 6 mm
Sector: sewage technology, food industry
Location: throughout Europ

Discharge silencer in stainless steel

Silencers also fall within the scope of the Pressure Equipment Directive (PED) when the operating pressure is greater than 0,5 bar. Discharge silencers are designed in round form, typically 3 – 10 mm thick and ideally with dished ends. An air pressure test is recommended on account of the interior fittings. The acoustic interior fittings can be produced as a circumferential baffle with an absorptive core. Both pressure and temperature have to be taken into consideration when designing the silencer.

Material: 1.4301 pickled
Diameter: DN 1.250 mm
Type: absorption silencer
Sector: mechanical engineering
Location: Germany

Silencers for compressor units

Silencers are used in oxygen stations containing rotary blowers. Because of the alternating pressure loads, especially high demands are placed on the vessel and their noise protection devices. The vessels are ideally of round design; the interior fittings are a combination of absorbent filling with a special cover plate for the protection of the mineral wool. To reduce the low frequencies, the absorbers are combined with panel resonators.

Filter tank at the LBF-pickling facility

When designing filter tanks, not only pressure and temperature is considered, but also resistance to corrosion. Different types of stainless steel can be used for this, depending on the medium found in the exhaust air. First, stainless steel tanks are full-surface pickled – exterior and interior – by our experts in our own LBF-pickling facility. Next, passivation then ensures long-lasting corrosion resistance. For aggressive media, additional interior coatings can be applied.

Overpressure: 30.000 Pa
Weight: approx. 500 kg

Filter tank in carbon steel

The tank is used as a pulse filter. The upper and lower chambers are separated by a gastight welded shelf. The dust which accumulates when cleaning the pulse filter enters the dust collecting container through a cone. This is conveniently connected to the tank by a clamp. The filter cartridges can be checked and, if needed, exchanged through an inspection opening. Production is based on customer’s drawings.

Project Information 
Material: S235JR, exterior and interior painted
Diameter: DM 1.600 mm
Application: pulse filter
Sector: automotive engineering
Location: Europe

Filter vessels in stainless steel

The filter vessel is considered a pressure vessel due to its operating pressure and falls within the scope of the Pressure Equipment Directive (PED) 2014/68/EU. First the design is made in accordance to the AD-Merkblatt, then drafting and a TÜV design review follow. The casing is welded in accordance to the regulations of the AD-Merkblatt. Testing, done in the presence of the TÜV, includes X-ray, pressure tests and final inspections. Complete documentation is provided which includes operating instructions and hazard analysis.
