Hollow-Walled Spiral Wound Pipe: The "Underground Artery" of Industrial and Construction Fields

In the field of construction engineering, hollow-walled spiral wound pipes demonstrate extensive application value. They can be used in various scenarios such as building rainwater downpipes, underground drainage pipes, sewage pipes, and ventilation pipes. These pipes feature smooth inner and outer surfaces, connected by square spiral ribs between the walls, classifying them as flexible pipes. They offer good extensibility, strong pressure resistance, and high adaptability to uneven settlement, enhancing the seismic resistance and disaster mitigation capabilities of public utilities.

When used as building rainwater pipes, the smooth inner wall of hollow-walled wound pipes provides superior drainage performance, allowing for rapid rainwater discharge and preventing water accumulation issues. In applications for underground drainage and sewage pipelines, the pipes exhibit excellent sealing performance. Connection technologies such as electro-fusion bands or heat-shrink bands enable fast construction, high connection quality, and great joint strength, achieving zero leakage at the joints and effectively preventing groundwater contamination from sewage seepage.

In ventilation duct applications, hollow-walled wound pipes are lightweight and easy to install, weighing only about one-eighth of concrete pipes, which facilitates transportation and construction. The pipes can operate normally within a temperature range of -50°C to 60°C without freezing cracks or expansion leaks, offering wide adaptability and low constraints from seasonal or temperature variations during construction.

Connection Methods and Sealing: The predominant connection methods for these pipes in construction include electro-fusion band connection and heat-shrink band connection. These methods ensure the joint's material and structure are consistent with the pipe body itself, creating a robust, integral seal that is crucial for preventing leaks in drainage and sewage applications.
