Application:

Drainage inside buildings as wastewater pipe, rainwater pipe, ventilation pipe
(see also areas of application: DIN 1986-4).

This pipe system can be easily inserted, installed, assembled, and laid through socket connections into the chamfered pipe end (spigot side).
During assembly, the pipe is pulled out one centimeter after complete insertion to create an effective length compensation.
When laying the pipes and fittings, it is important to ensure that the wastewater does not back up or solid parts accumulate, which could clog the pipe system.
A minimum slope of 2 cm per meter is required. HT branches and other fittings are therefore equipped with a maximum angle of 87 degrees (3 degrees slope) to the main pipe.

The diameter of the HT drainage pipe system should neither be too small nor too large. Too large diameters reduce the sufficient floating depth of solids. Deposits and blockages could result. Too small pipe diameters pose the risk of the pipe filling completely. The resulting air seal can suck out the odor trap. Odors from the downpipes could rise from the drain into living spaces.

HT pipes can be cut to any length with a metal or fine saw. A miter box can be used. Saw edges should be chamfered to achieve a proper connection between the HT pipe and subsequent parts. Burrs inside the pipe should also be removed to prevent damage to seals and accumulation of deposits.

Material properties

Pipes and fittings made of polypropylene with the ability to withstand hot water, manufactured according to DIN EN 1451-1.

• Temperature application areas: -20° to 90°
• High chemical resistance; pH 2-pH 12 (acidic-basic) stable against biogenic sulfuric acid corrosion
• High abrasion resistance of polypropylene, resulting in longevity and operational safety
• Excellent impact resistance and toughness
• Low tendency to crack formation and crack propagation
• Robust behavior under mechanical stress (e.g., high-pressure flushing)
• Smooth surfaces, optimal hydraulics
• No incrustation, deposits cannot settle
• Self-cleaning, resulting in long maintenance intervals
