Heat resistant, polypropylene effluent pipes, manufactured as per the CSN EN 1451-1 standard. Internal connection, effluent, ventilation and conductance piping in buildings (class "B" application) with higher thermal or chemical load, yet without requirements for reduced flammability.
Maximal operating temperatures can be found in individual catalogues of waste and sewage systems and sealing.
| constant | short-term |
|---|---|
| 90°C | 100°C |
| Sealing | Area of application- temperatures |
|---|---|
| SBR (at the producer /within the range of Work) | cca. -50°C up to +100°C |
| EPDM | cca. -50°C up to +150°C |
| NBR (can be ordered separately) | cca. -30°C up to +100°C |
| SBR | Improved abrasion resistance and age resistance, good resistance against operating liquids |
| EPDM | Excellent fastness to abrasion, ageing and fastness to most of operating liquids |
| NBR | Versatile material. Sealing for contact with mineral oil or fuels. Poor resistance against ozone and weather resistance. |
| HT-System (PP) PLUS® (DN 32 - DN 160) | according to the standard ČSN EN 1451-1 |
We can recommend KG 2000 Polypropylene®, or HT-System (PP) ® with sealing rings made of NBR as the case may be.
| HT-System (PP) PLUS® | DIN 4102, B 2 |
The sealing of systems BL, DD and Euro L Spezial are resistant against water with maximal volume of chlorine 0.6 mg/l.
See the Test record of MPA Darmstadt „K 04 1525" of 1st December 2004 (the pipes DN 40 + DN 50 were tested).
No, it cannot. Among other things, this provision serves for elimination of the backwater formation and formation of retained amount inside the system.
No, it's not.
These details can be found in the assembly instructions of HT-System (PP)® - Article 5 and assembly instructions of Skolan dB – Article 7.
„The pipes with slide-in sleeves / couplings are usually placed in such manner that the sharp end is in direction of flowing. The sharp end is sliding into the sleeve / coupling.
The quote from Manual of plastic pipes (4th issue, paragraph 3.4.4 Construction of the sewage water channels and piping, page 463):
Thus the piping placement in direction of flowing is clearly defined.
