Pre-stressed plastic corrugated pipe equipment is mainly used in the formation of holes in pre-stressed projects such as post-tensioned pre-stressed tendons and slope anchor cables. Product overview Prestressed plastic corrugated pipe is a single-wall corrugated pipe extruded from high-density polyethylene through a plastic extruder. It is used as a perforated pipe for prestressed steel reinforcement in post-tensioned concrete structures.
It is an ideal product to replace the original metal bellows in bridge and building construction. Plastic corrugated pipes are divided into round pipes and flat pipes, which are connected by various plastic connectors in actual use. The raw material of the prestressed plastic corrugated pipe is high-density polyethylene. Its corrosion resistance is far better than that of metals, and it is not afraid of acid and alkali corrosion. It will not corrode itself and can effectively protect the prestressed tendons from corrosion. Many prestressed structures are subject to severe external influences, such as deicing salt or salt water. When post-tensioned components collapse due to waterproof layer, micro-crack leakage, and blockage or failure of drainage facilities, the pre-stressed steel bars may be corroded.
