Product description
Ductile pipes and tee fittings of the NATURAL program are suitable for transport and distribution pipelines in urban and rural areas. The NATURAL products are available in sizes between 60 and 2000 mm as well as in pressure classes C40 (DN60 - DN300), C30 (DN350 – DN600) and C25 (DN700 – DN2000).
The NATURAL type pipes combine the existing experience with future technologies:
- Robustness of pipes from ductile alloy
- Simple laying and quick installation
- operating reliability
- durability
The NATURAL joints consist of a pipe with STANDARD terminals linked to EXPRESS or STANDARD tee fittings.
External protection, typically recognizable by its blue color and (Bio)Zinalium® technology ensures long-term durability under earth conditions.
The BioZinalium® consists of 2 layers:
- copper enhanced ZnAl alloy at a ratio of 85-15 at 400 g/m2; in addition copper prevents local “bio corrosion” on the pipe walls
- protective layer for sealing pores, of typical blue color
The internal layer of the NATURAL program is represented by a centrifugally applied cement mortar as a standard feature. It offers good hydraulic properties, protects against the »aggressiveness« of water and maintains its quality. For extreme conditions there are also NATURAL PUR pipes available featuring an internal coating made of two-component polyurethane material free of any solvents.
