Steinzeug Keramo N.V. products

For the safety, reliability and economic viability in waste water treatment we produce Cradle to Cradle certified vitrified clay pipes and fittings in excellent quality using the latest processing technology. Our system solutions meet the most demanding requirements for environmental responsibility, sustainability and service life: from the extraction of natural raw material clay through efficient processing in high-tech production plant, professional installation, more than one hundred-year-long operating life up to one hundred percent recycling potential.

Dimensions b1 and b2 are standard gauges. Bends of 90° are only used for the connection of downpipes. They are not permissible within drainage system lines Other dimensions and compressive forces such as pipes. Larger sizes on request. Vitrified clay pipes and fittings are standardised in EN 295-1. Supplementary Requirements defines the certification program ZP WN 295.  All measurements - especially when connecting to third-party products - must be checked and depend on the specifications of EN 295 and on the certification program ZP WN 295. Subject to technical changes.

The dimensions z, a and e are reference values. Other dimensions and crushing strengths: see pipes. The strength class of the branch piece is always normal strength.

Please note: The maximum permissible jacking force must be calculated in each case according to the applicable regulations, e.g. DWA-A 161 of March 2014 . - Values given here serve only as a guide for planning. This is subject to the condition that the effective jacking forces are continuously monitored and logged during the jacking process. The maximum pressure of the jacking device must be limited to the permissible jacking force. Our smaller-diameter KERA.Drive jacking pipes have proven themselves over many years of use, both for house connections and for main sewers up to DIN 200. DN 150: Glazed both inside and outside, guide ring made of glass-fiber-reinforced polypropylene.

Manhole connector part A DN 250 - 300. Manhole connector part B DN 250 - 300. Manhole connector part C DN 250 - 300.

For sizes DN 800 to DN 1000, concrete cover slabs are produced. These are reinforced to the requirements of traffic load D 400. Up to DN 1000, the cover slabs are finished with corresponding recesses on the underside to secure them against displacement.

Standard manholes are equipped with a one-piece PU channel element with integrated manhole connections from DN 150 to DN 400 in the smooth pipe cylinder, as well as internal integrated buoyancy protection.

PLAY – our new universal coupling lives up to its name, allowing  you to connect pipes with ease even if they are different sizes. Everyone knows that pipes know no standards. Different materials with different surfaces and different outside diameters often turn up in the same stretch of pipeline. And this is exactly where PLAY comes in!
