Description

Polypropylene waste pipes suitable for internal sewage systems where higher temperature or chemical stress occurs. The system is designed for the construction of connection, waste, ventilation and drainage piping inside buildings (area of use B) without requiring reduced flammability.

HT System PLUS – professional solution for internal sewage systems

Waste pipes and fittings HT-System PLUS (PP) represent a high-quality system for internal sewage systems, which is based on the needs of modern construction and architecture. During their development, emphasis was placed on high mechanical and hygienic requirements, long service life, reliable function and also environmentally friendly manufacturing. The entire system meets the requirements of the ČSN EN 1451-1 standard.

Why choose HT System Plus

Smooth surface = safe operation and minimal clogging

Thanks to advanced manufacturing technology, pipes and fittings have a perfectly smooth internal and external surface. This surface contributes to excellent hydraulic properties, prevents sediment accumulation and enables long-term stable operation without frequent repairs or cleaning.

Socket joints use multiple sealing, which together with the smooth pipe surface guarantee:

  • perfect tightness
  • long-term joint flexibility
  • reliable function even with temperature changes
  • resistance to pressure and deformation

This type of joint provides significantly higher safety compared to traditional solutions and minimizes the risk of leakage or failure.

For the production of HT System PLUS, high-quality polypropylene (PP) is used. This is a material that gives the piping:

  • exceptional toughness
  • temperature resistance
  • chemical resistance
  • long-term dimensional stability

Thanks to these properties, the system has an extremely long service life even under demanding conditions and regular loading.

Universal use and compatibility with old piping

HT-System PLUS is completely designed to be fully compatible with the requirements of domestic construction. Its major advantage is easy connectivity to existing and older types of sewage piping.

You will especially appreciate this during renovations, extensions, or expansion of existing sewage systems. You do not have to invest in a complete replacement of the original pipes – HT System PLUS can fully adapt to it.

Simple and quick installation

Connection using push-fit sockets with elastomeric sealing rings is not only fast but also extremely reliable. Compared to adhesive or welding systems:

  • requires no drying time
  • reduces installation time
  • allows immediate pressure testing
  • guarantees perfect sealing immediately after assembly

This installation method is ideal for both professional companies and users who want to perform part of the work themselves.

Ecology and recycling

The production of HT-System PLUS takes environmental protection into account. The material is:

  • 100% recyclable
  • during thermal decomposition does not produce toxic substances
  • can be processed repeatedly without loss of key properties

According to standards, the material lasts up to 100 years in operation and, thanks to its recyclability, represents a long-term sustainable solution for the future.

FAQ

Is it permitted to shorten fittings?
It is not permitted.
Use of HT-System (PP) pipes in central vacuum systems
For central vacuums, the Skolan SAFE dB sewage system meets the requirements.
May the dimensioning of the sewage / drainage system be reduced (narrowed) in the direction of flow?
No! Among other things, this provision serves to exclude the creation of (backflow) pressure and retained volume within the system.
Assignment of products to standards / certificates
Waste pipes HT-System PLUS (PP) (DN 32 - DN 160) are manufactured according to the ČSN EN 1451-1 standard.
What is the distance between brackets for horizontal installation of HT-System PLUS (PP)?
This information is contained in the installation manual for waste system HT-System PLUS (PP) p. 29.
Maximum operating temperatures of pipes, fittings and seals

Maximum operating temperatures can be found in the individual catalogs of waste and drainage systems and seals.

permanent temporary
90°C 100°C

Seals Areas of use - temperatures
SBR (at manufacturer/on site) approx. -50°C to +100°C
EPDM approx. -50°C to +150°C
NBR (can be ordered separately) approx. -30°C to +100°C

SBR Improved resistance to wear and aging, good resistance to operating fluids
EPDM Excellent resistance to wear, aging and most operating fluids
NBR Versatile material. Seals for contact with mineral oil or fuel. Poor resistance to ozone and weather conditions.
Which drainage system is suitable for wastewater containing grease (in canteens, commercial kitchens, industry, gastronomy, etc.)?
Can be recommended drainage system KG 2000 Polypropylene for the field of use "UD" – under the foundation plate and outside the building in the ground. For internal waste (field of use "B") HT-System PLUS (PP) and Skolan SAFE dB with sealing rings made of NBR.
Direction of installation of plastic pipes
Installation of waste pipes with socket pipes / couplings is generally carried out so that the tapered end is in the direction of flow. The tapered end is inserted into the socket / coupling.

Quote from the plastic pipes manual (4th edition, section 3.4.4 Construction of sewers and waste water pipes, page 463)

Based on this, the installation of pipes in the direction of flow is clearly defined.
Behavior of waste pipes in case of fire
Waste pipes HT-System PLUS (PP), Skolan SAFE dB a Ultra dB System are classified according to DIN 4102 in class B2 - normally flammable substances (see catalogue p. 31). Quote from the plastic pipes manual (4th edition, section 3.4.4 Construction of sewers and waste water pipes, page 463)

Based on this, the installation of pipes in the direction of flow is clearly defined.
What is the chemical resistance of M.O.L. seals against "swimming pool water"?
Seals of BL, DD and Euro L Spezial systems are resistant to water with a maximum chlorine content of 0.6 mg/l.

Based on this, the installation of pipes in the direction of flow is clearly defined.
Is gluing HT-System PLUS (PP) permitted?
Gluing is not permitted. Due to the properties of the primary material PP-MD, it is not possible to guarantee the tightness of the glued joint for the lifetime of the sewer system.
