Puddle Flange – Watertight up to 10 bar
Puddle Flanges are watertight up to 10 bar and easy to install, FRANK puddle flanges have been designed specifically for the pressure-tight installation of pipelines in concrete walls, tanks, shafts, foundation plates, manholes and basements.
Installed on the external pipe surface to act as a barrier, they diffuse gases and hydrocarbons and are suitable for all standard steel, plastic, clay, concrete and cast iron pipes from DN20 to DN3200 mm making them a perfect solution for any application.
Puddle flanges applications:
- To prevent water or gas getting into buildings via pipe penetrations
- Domestic and commercial developments
- Suitable for use with all smooth walled pipes provided that the pipe surface, at the point of installation, is clean, smooth and free of pores or surface imperfections
- Most pipe sizes can be accommodated from 20mm through to 3200mm diameter (Please email sales@arsstore.co.uk with your requirements)
- Installed on pipes during construction where water penetration has to be prevented
Notes:
- Puddle flanges are supplied with the ID smaller than the host pipe OD and are stretched over during installation.
- Concrete coverage should be at least 50mm against each surface of the puddle flange using waterproof concrete.
- Depending on the size, puddle flanges have an OD 75-100mm larger than the host pipe OD.
- The pipe must be fully supported to withstand the concrete pouring process as puddle flanges do not provide any axial restraint.
Benefits:
- Tested up to 10 bar water pressure.
- Easy to install and a cost effective solution.
- Can be installed in walls, floors and ceilings
- Good general chemical resistance.
