How much is one meter of Changzhi Jincheng Shandong corrugated pipe [Plastic Corrugated Pipe] Price
Prestressed plastic corrugated pipe is a raw material and a new type of hole-forming material. It is mainly used in post-tensioned prestressed cement structures and hole forming of tie rods. It has good sealing performance, no water leakage, high ring stiffness, small friction parameters, aging resistance, resistance to electrical erosion, good flexibility and elasticity, and not easy to be damaged. The advantages of tamping and new connection methods make construction connection more convenient. When the hole-forming material is damaged, the paddle is the last protective barrier for the prestressed steel plate in the prestressed cement structure.

The slurry is the last step of the prestressed steel in the prestressed concrete structure. A protective barrier. Plastic corrugated pipe is a new type of hole-forming material. Compared with metal corrugated pipe, it has the following advantages: 1. The raw material of prestressed plastic corrugated pipe is. Its corrosion resistance is far better than that of metal. It is not afraid of acid and alkali corrosion. It does not corrode itself and can effectively protect the prestressed tendons from corrosion
. Many prestressed structures are exposed to severe external influences, such as de-icing salts or brine. Prestressed tendons may be subject to corrosion when post-tensioned members fail due to collapse of the waterproofing layer, leakage from microcracks, and blockage or failure of drainage facilities. The Grouting of Prestressed Tendons in the "Construction Guidelines ()" states that metal pipes do not have permanent anti-corrosion capabilities and are not sufficient to resist water leakage and reach the grout and prestressed tendons. Prestressed plastic corrugated pipes can provide a barrier protection function for prestressed tendons that is far superior to metal corrugated pipes, and can prevent harmful substances from penetrating the pipeline and contaminating it, thereby ensuring better durability of the post-tensioned prestressed structure.

Prestressed plastic corrugated pipe reserved
The friction coefficient of the hole is significantly smaller than that of the metal bellows pre-stressed pipe The friction coefficient of the holes is left to reduce the friction loss of the prestress during the tensioning process. Generally, the friction coefficient of plastic corrugated pipes is taken and that of metal bellows is taken. Prestressed plastic corrugated pipes have high strength, are not afraid of being stepped on, and are not easily broken by vibrators. Their sealing performance and anti-leakage performance are higher than Metal corrugated pipes are more suitable for vacuum grouting
3. Prestressed plastic corrugated pipes are not conductive and can prevent stray current corrosion, while metal is a good conductor of electricity
4. Prestressed plastic corrugated pipes are more Good fatigue resistance can greatly improve the fatigue resistance of components.
Prestressed corrugated pipes are mainly divided into metal corrugated pipes and plastic corrugated pipes. Metal corrugated pipes are mainly composed of two materials, one is black steel strip and the other is galvanized steel strip.
The processing technology mainly uses the machine processing of corrugated pipes. The wavy ports are interlocked with each other and made in circles.
