FRANK puddle flanges. The original.
In the early 1980s, FRANK developed and patented the FRANK puddle flange, a sealing system in use today in millions of buildings and structures all over the world. The original.
The FRANK puddle flanges, suitable for all standard pipes in steel, plastic, stoneware, concrete and cast iron from d 20 to d 3200, have been specifically designed for the pressure-tight installation of pipelines in concrete walls, foundation plates and manholes. FRANK puddle flanges are
pressure-tight up to 10 bar, preventing the ingress of pressurised water, diffusing media such as gases (e.g. radon) and hydrocarbons (e.g. oil, petrol). The FRANK puddle flange is an extremely flexible
product available in a range of versions. A perfect solution for any application! Easy to install. Cost-effective alternative to conventional sealing systems.
FRANK puddle flanges: Protection against radioactive gas
Radon-resistant, gas-tight puddle flanges from FRANK
Radon is a naturally occurring radioactive gas and comes from the natural radioactive decay of uranium and thorium. These metals occur naturally in bedrock and the release of radon therefore depends on
the local geology. You cannot see, smell or taste radon. The gas diffuses through the soil and is released into the atmosphere where it is found in very small concentrations. Outside of buildings, radon is therefore not a problem. The gas can however enter buildings, for example through cracks and joints, defective foundation plates in the basement or the ground floor, or along cable and pipe ducts. In this case, the radon concentration builds up gradually, often exceeding the limit values recommended by the German Federal Office for Radiation Protection. Tight foundations, solid constructions and special ventilation measures help keep the radon concentration in buildings low. When installing pipes and cable ducts through building walls, we therefore recommend using the special orange FRANK puddle flanges which are tested for radon-tightness.
Pressure-tight up to 10 bar!
Safe and versatile
Externally tested and certified
The independent material testing institute MFPA Leipzig GmbH checked the FRANK puddle flange for
its sealing effect and, with professional installation with at least 50 mm coverage in waterproof concrete, confirmed - depending on diameter and design - a sealing effect of 5 bar to 10 bar.
Characteristics FRANK puddle flanges made in EPDM
EPDM is chemically resistant to a wide range of acids and bases. It also offers outstanding weather and ozone resistance. For applications in connection with oil and petrol, FRANK puddle flanges made in NBR are the preferred option.
