Wavin PVC External Sewer Inspection Chamber

External sewer inspection

PVC - Unplasticized PVC is a rigid material. It is characterized by high resistance to the effects of acidic and alkaline solutions, as well as high hardness and shape retention at elevated temperatures. Unplasticized PVC is chemically resistant to alcohols, oils, aliphatic hydrocarbons, gasoline, and many other chemically aggressive substances and compounds.

Structurally, each pipe has a socket with a rubber sealing ring inserted into the inner surface groove at one end. The smooth end of the pipe is marked up to which the pipe must be inserted into the socket during installation. Thus, a 10 mm compensation gap is created during installation, which accommodates the expansion of the pipeline if the temperature of the wastewater increases.

N and S class PVC pipes are used for the collection and disposal of wastewater if the constant temperature does not exceed +60°C. Temporary (up to 2 minutes) increase in wastewater temperature up to +100°C is permissible (at a flow rate of up to 30 l/min or 8 m/s).
