What are the advantages of the prestressed corrugated pipe production line under the same conditions
What are the advantages of the prestressed corrugated pipe production line under the same conditionsWhat are the advantages of the prestressed corrugated pipe production line under the same conditions, as well as some other basic knowledge, let’s take a look:
Chinese name: prestressed reinforced plastic corrugated pipe
English name: pre-stressedplasticcorrugatedpipe
Material: HDPE
Advantage: anti-corrosion
Function: resistance to electrical corrosion, good flexibility
Raw material advantage
When the raw material of the hole is damaged, the slurry is the final safety protection natural barrier for the prestressed steel stainless steel plate in the prestressed steel reinforced concrete. Plastic corrugated pipe is a new type of raw material for piling. Compared with corrugated hose, it has the following advantages:
1. The raw materials of pre-stressed steel metal bellows are mostly manufactured by extrusion of re-made HDPE particles. Its characteristics stipulate that the raw materials have high compressive strength and good flexibility, so that the manufactured pipe fittings can meet the national standards and specifications. The key production and manufacturing regions of steel reinforced plastic corrugated pipe raw materials are concentrated in "Miluo City, Yueyang, Hunan" and surrounding cities. Many companies that have been engaged in the development and design of manufacturing raw materials in China are: "Miluo Rixing Recycled Plastic Factory, Hunan Zhongjianri "Prosperous Pipe Industry", because of its early entry into the industry, it has promoted the relative improvement of technology, production capacity and service projects. Because of the early practice of the company, the company has occupied a key industry in the supply of raw materials for prestressed reinforced plastic corrugated pipes. The goods involve regions all over the country. The corrosion resistance of the prestressed steel metal bellows is far better than that of metal materials. It is not afraid of acid and alkali corrosion. It does not corrode itself and can reasonably maintain the prestressed steel bars from being corroded. Many pre-stressed steel structures bear more serious external hazards, such as melting ice salt or salt water. When post-tensioned prefabricated components are broken or ineffective due to ground waterproofing, micro-crevice water seepage, and drainage pipeline equipment blockage or ineffectiveness, the pre-stressed steel bars are likely to suffer from erosion. The "grouting of prestressed steel bars" in the "FIP Construction Guide (1990)" emphasizes that metal hoses do not have a long anti-corrosion ability to resist water leakage and reach the slurry and its prestressed steel bars. The pre-stressed reinforced plastic corrugated pipe can show a natural barrier maintenance effect for the pre-stressed steel bar, which is far better than that of the corrugated hose. It can avoid the environmental pollution of harmful substances through the pipeline, thereby ensuring the structure of the post-tensioned pre-stressed steel bar. Have stronger performance.
Prestressed corrugated pipe production line
2. Under the same conditions of the products of the prestressed corrugated pipe production line, the friction resistance of the embedded holes of the prestressed steel plastic corrugated pipe is significantly lower than the friction resistance of the embedded holes of the corrugated hose, which reduces the prestressed steel during the whole process of prestressing and stretching. The friction damage. Generally, the friction resistance of the plastic bellows is 0.14, and the friction resistance of the corrugated hose is 0.25; the compressive strength of the pre-stressed reinforced plastic bellows is high, it is not afraid of stepping on it, and it is not easy to be broken by vibrating force. The sealing performance and anti-leakage performance are higher than the corrugated hose, which is more suitable for vacuum pump grouting;
3. The main purpose of prestressed steel reinforced metal bellows, roads, railway lines, highway bridges, multi-storey buildings, large span prestressed tensioning.
4. The color tone will not be restricted, and various colors can be changed according to the construction regulations. The general color tone is mainly gray and black.
