Sitech Plus PP-HT pipe 160x500 sanitary, for low-noise internal drainage, black color 3097807

Sitech Plus drainage pipe – a quiet and efficient installation

Sitech Plus PP-HT pipe is a three-layer solution designed for the construction of internal gravity drainage systems. It is characterized by high resistance to loads and effective noise reduction, making it an ideal choice for both professional installers and users who value comfort. Made of polypropylene (PP) with the addition of minerals, it ensures durability and reliable operation for years to come.

### Construction and properties

The Sitech Plus pipe is distinguished by its unique three-layer construction. The outer layers, made of PP copolymer, provide mechanical strength and chemical resistance, while the core made of PP copolymer or PP recyclate with mineral filler affects the stiffness and stability of the pipe. The black color of the pipe facilitates identification in the drainage system. The outer diameter of the pipe is 160 mm, and the wall thickness is 5 mm. The circumferential stiffness class SN4 guarantees adequate resistance to external loads. The standardized dimension ratio (SDR) is 33.

The Sitech Plus pipe is chamfered, which facilitates connections with the WAVIN SiTech+ system fittings. Push-fit sockets are the standard way of connecting system elements. This makes installation quick and easy, and the connections are tight and durable. The pipe 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 maximum working pressure at maximum temperature is 0.5 bar.

### Application and benefits

The WAVIN SiTech+ system with the Sitech Plus pipe is widely used in residential, commercial and industrial construction. It is ideal for:

* **Sanitary drainage:** draining domestic wastewater from apartments, houses, hotels or hospitals.

• Underfloor drainage: installation inside floors and ceilings, where minimizing noise is important.

• Rainwater drainage: draining rainwater from roofs and paved surfaces (up to a height of 40m when using heat-shrink sleeves).

• Technological drainage: draining industrial wastewater with appropriate chemical composition (chemical resistance must be checked).

Advantages of the Sitech Plus pipe:

* **Low noise emission:** thanks to its special three-layer construction, the pipe effectively dampens the sound of flowing water, providing acoustic comfort in the building – the weighted sound level of the material Lsc,A is 15 dB(A) at a flow rate of 4 l/s (according to PN-EN 14366:2006).

• High chemical resistance: PP material is resistant to many chemicals contained in domestic and industrial wastewater (check the ASTOLAN® chemical resistance list).

• Durability and reliability: high-quality materials and precise production technology guarantee the long service life of the system.

• Easy installation: the push-fit connection system allows for quick and trouble-free installation without the need for specialized tools (except for a chamfering tool).

• Wide range of diameters: the availability of different pipe diameters allows the system to be adapted to individual project needs.

• Compatibility with other systems: compatibility with other Wavin internal drainage systems through the use of appropriate transition fittings (ø 50/56 and ø 75/70).
