Self-stressing drainage pipe molds are concrete pipes that generate prestress without tension. Their construction involves arranging ring-shaped prestressed steel bars within the pipe wall, followed by pouring self-expanding concrete. As the concrete hardens and expands, it pushes the ring-shaped prestressed steel bars outwards, and the reaction force of the prestressed steel bars on the concrete generates prestress.

Before purchasing and using the equipment, relevant operators should understand the mold and be familiar with the operating instructions. If any questions arise during use, consult a professional promptly. For more detailed information on purchasing equipment and molds, please feel free to contact us by phone.
