PP-HT Sitech Plus pipe 75x1000 sanitary, for low-noise internal drainage, black color 3091157

Drainage Systems – Efficiency and Comfort

Wavin Sitech Plus PP-HT pipes are an advanced solution for constructing internal drainage systems, especially those where noise reduction is important. This system, produced by WAVIN, combines durability, chemical resistance and sound-dampening properties, making it an ideal choice for both installers and end-users. The pipe with a diameter of 75 mm and a length of 1000 mm is made of polypropylene (PP), which guarantees its light weight and ease of installation.

Construction and Properties

Sitech Plus pipes are characterized by a three-layer construction. The outer and inner layers are made of PP copolymer, while the core is made of PP copolymer or PP recyclate with the addition of a mineral filler. This construction provides high ring stiffness (SN4 class) and resistance to mechanical damage. The pipe wall thickness is 2.6 mm, and the outer diameter is 75 mm. Additionally, the pipe has a chamfered edge to facilitate connections. This system is designed to operate at temperatures from -10°C to 90°C (continuous flow) and short-term exposure to temperatures up to 95°C. The coefficient of thermal expansion is 0.12 mm/(m·K).

Application and Benefits

Wavin Sitech Plus pipes are widely used in residential, commercial and public utility construction. They are ideal for sanitary installations where noise reduction from flowing wastewater is required. This ensures user comfort in apartments, hotels, hospitals and other facilities sensitive to sound. Connections are made using push-fit fittings, which simplifies and speeds up installation. The black color of the pipe (RAL 9005) facilitates identification of the system in the installation. The maximum working pressure at maximum temperature is 0.5 bar. The pipe wall roughness is 0.02 mm, which reduces flow resistance and limits the deposition of contaminants.
