Application: The vertical HDPE/PP/PVC large-diameter double-wall corrugated pipe production line developed by Tongsu Company is mainly used in urban drainage and sewage systems.
Performance and advantages: 1. Fast production speed and high output: We creatively added a modular water mist cooling system to the vertical molding machine, which greatly improved the production speed. At the same time, our patented sizing sleeve design can make the bellows cool faster, and the production efficiency is greatly improved.
2. More optimized waveform design, bellows lighter in meter weight and higher ring rigidity.
3. High-quality components ensure the long-term stable production of the equipment.

Application: The horizontal HDPE/PP/PVC double-wall corrugated pipe production line developed by Tongsu Company is mainly used in urban drainage and sewage systems.
Performance and advantages: Professionally designed and well-manufactured TSBW horizontal series HDPE/PP/PVC double-wall corrugated pipe fully computerized extrusion production line has the advantages of high output, stable extrusion, high automation and low energy consumption Etc.

Application:Steel strip corrugated spiral winding pipe production line has the advantages of high-speed production, reliable winding welding (with patent), low energy consumption, and large production caliber range.
Features and Benefits:
● Safe and reliable, high ring rigidity, smooth inner wall, flow resistance 20-30% lower than cement pipe.
● Flexible or leak-free (electrofusion, stainless steel clamp) connections.
● Light weight, less joints, no need for large installation equipment, convenient and quick installation and laying.
● Corrosion resistant for over 50 years.

Product performance advantages:
● Excellent connection with zero leakage.
● The matching ability of pipes and fittings is strong.
