Another common problem is pipe corrosion. Sčasoma se kanalizacijske cevi poslabšajo zaradi kemičnih reakcij z odpadno vodo, ki jo prenašajo. To še posebej velja za starejše cevi iz materialov, ki so manj trpežni kot sodobne alternative. To combat this problem, many municipalities and construction companies are turning to spiral-welded steel pipe, known for its strength and durability. These pipes form the backbone of efficient and reliable sewage and wastewater transport infrastructure, ensuring that the system will stand the test of time.

Za tiste, ki sodelujejo pri gradnji in vzdrževanju kanalizacijskih sistemov, je enako pomembno razumeti uporabljene materiale. This factory in Cangzhou, Hebei Province, has been a major player in the industry since its establishment in 1993. With a total area of ​​350,000 square meters, total assets of RMB 680 million and 680 skilled workers, the company is committed to producing high-quality spiral welded steel pipes. These pipes are not only strong, but also designed to withstand the harsh conditions commonly found in sewer systems.
