PP-HT reducer

PP-HT indoor sewage fittings comply with standard EN 1451

The pipes and fittings are made of copolymer polypropylene (PP-c).
Advantages compared to other plastics:

• Withstands both high temperatures (up to 110 °C for short periods) and low temperatures (including freezing), making it well-suited for Nordic conditions
• High chemical resistance
• Four times greater impact resistance compared to PVC - Does not release substances harmful to health

Stiffness classes:
According to EN 1451, pipes are divided into three classes based on wall thickness and ring stiffness:
S20 – ring stiffness ≥ 2 kN/m²
Permitted for indoor installation only; must not be embedded in concrete.
S16 – ring stiffness ≥ 4 kN/m²
Permitted for both indoor and underground installation; may be embedded in concrete.
S14 – ring stiffness ≥ 6.3 kN/m²
Permitted for both indoor and underground installation; may be embedded in concrete.
Color coding by diameter:
Pipes and fittings Ø 32, 40, and 50 mm – white
Pipes and fittings Ø 50, 75, and 110 mm – grey
