Why Wiitta's pipe fittings are chosen?
Wiitta is a world-class expert in the manufacture of pipe fittings.
Our products are designed to withstand harsh conditions and meet exacting industry standards. We manufacture our pipe fittings with care and precision, ensuring their longevity and reliability.
Wiitta sewer pipe joints are made of polypropylene copolymer plastic (PP-C) in accordance with European standards EN 1451-1 and EN 1852-1. The products are intended for the drainage of normal waste and rainwater both inside and outside buildings. The joints are reliable, easy to install and quiet in use.
First class pipe fittings
We use only premium polypropylene as the raw material for our products. We work with Europe’s leading raw material manufacturers, so we are guaranteed to provide our customers with a high quality product.
We do not use fillers in our products, but their strength is based on the structure and the high strength of the raw material, to which we add only a small amount of dye.
Polypropylene has very good chemical resistance, making it ideal for industrial plants, laboratories and drains for fuel distribution points.
The standard products can also be installed in drainage systems with sewer pipes sized according to the same millimetre dimensions, also in other materials such as PP-MD (EN 14758, NPG/PS 102) and PVC (EN 1401, EN 1329).
Our company has ISO 9001:2015 certification as proof of an audited quality system. The pipe connections are Nordic Poly Mark certified. Our products are backed by decades of experience and reliability.
Excellent sound qualities
Top sound quality as standard! We tested the sound quality of our products at the prestigious German Fraunhofer laboratory. Why pay extra for a decibel drain when you can get a good one as standard?
- Wiita’s standard system sound level 14 dB (flow rate 2 l/s)
- The standard Wiita system has a sound level of 17 dB (flow rate 4 l/s) = well below the requirement of 20 dB
- Fire performance class B2
Specificities
- Wiitta products have strong walls and are sturdy to use and install.
- The sealing surface of the plug head is seamless and does not cut the seal.
- EPDM as sealing material: better temperature resistance than commonly used SBR seals
- Can be disinfected with low-pressure steam
- If necessary, drainage pipes and connections also with oil-resistant nitrile gaskets.
