LIPP® Double-Seam

Flexible, safe and proven the world over – the LIPP® Double-Seam-System

Conventional systems are often unsuitable for the optimum, safe storage of solid or liquid substances and their use can result in premature corrosion, leaks and problems with safety. Flexibility is another important factor. Tanks must be flexible in terms of size and substrate and optimally adaptable to the local conditions.

  • Edgeless, smooth finish
  • Maximum leak-tightness
  • Automated, efficient production on site
  • Low installation and investment costs
  • Minimal installation space required
  • High static and dynamic stability
  • Available in stainless steel, VERINOX® stainless steel or galvanised/black steel
  • Substrate-flexible due to specific material selection
  • Low maintenance costs

LIPP Double-Seam process
LIPP Double-Seam process

The LIPP® Double-Seam-System has proven itself time and time again all over the world for more than 55 years: multi awarded.

The principle of the LIPP Double-Seam-System is as follows: the edges of steel strips are folded over together twice, connecting them together in such a way that even aggressive liquids inside the tank cannot find any surfaces to attack. The result: corrosion is prevented and maximum leak-tightness is achieved.

…for the optimum storage of solid, liquid and gaseous substances

Tanks and containers are manufactured from metallic materials which are matched to the chemical and physical properties of the respective media to be stored and processed in each case.

Characterised by outstanding quality, their extreme stability means that even the largest tanks are resistant to horizontal pressure so that maximum safety is guaranteed.

The effective way to prevent premature corrosion: an edgeless, smooth surface on the inside. Another specific benefit: the size of the tank is steplessly variable with available diameters of between five and more than 50 metres.

Easy installation – tried and tested in over 80 countries

The transportable assembly equipment also designed by LIPP enables steel strips to be made into tanks in the desired size and with a variable diameter on site, at any location. A tried and tested, optimally automated production method permits fast, flexible and efficient construction and requires minimal installation space.

The LIPP Double-Seam-System: the fastest, simplest and most flexible way to build reliable containers and tanks.
