Prestressed corrugated pipe manufacturer
Hengshui Sitong Engineering Rubber & Plastic Co., Ltd. is a well-known manufacturer of prestressed corrugated pipes in China. Since its establishment, it has not only its own factory, but also 150 production staff and 40 professional technicians. Over the past few years, we have been adhering to the principle of leading technology and quality first, and provided high-quality products for many new and old customers. Our projects are not only prestressed plastic corrugated pipe, but also plastic blind ditch, metal corrugated pipe, acoustic pipe, soft permeable pipe and so on.
In addition, Chengdu Yilin Pipe Industry Co., Ltd. is also a prestressed corrugated pipe manufacturer favored by Sichuan consumers and merchants. In recent years, Chengdu Yilin Pipe Industry Co., Ltd. has introduced a number of automatic plastic extrusion production lines. Not only that, but also it is equipped with advanced high-tech equipment, which greatly improves the overall production efficiency and product quality. The types and specifications of products provided are also increasing. Including: PVC single-wall corrugated pipe, HDPE single-wall corrugated pipe, PVC double-wall corrugated pipe, CPVC high-voltage power pipe, FRP cable protection pipe, HDPE double-wall corrugated pipe, PVC porous communication pipe and other related plastic pipes.
Installation of prestressed corrugated pipe
First, when corrugated pipe is buried in trench, it must be operated in accordance with the specified design requirements and standard construction steps. It must be placed as straight as possible. If the bottom of the ditch is uneven, it can be paved with fine sand. Moreover, all kinds of hard objects in the ditch should be removed before burying the pipe to avoid the deformation of the corrugated pipe due to hard objects in the later use process.
Secondly, during the installation and construction of prestressed corrugated pipes, each prestressed corrugated pipe may have a different length. At this time, it is necessary to measure the exact length of the pipe according to the length required by the actual environment and then saw it off. When sawing, you must pay attention to the smoothness of the incision, so as to have better sealing when connecting.
Third, when installing and laying the first section prestressed corrugated pipe, try not to fill the soil first. Try to use the cable perforator, and the subsequent pipeline laying project can only be continued after the successful perforation, which is more conducive to the later laying.
Four, after the installation and laying of prestressed corrugated pipe, it must be covered with fine soil or fine soil to reach the standard height. Remember not to let the bellows be suspended. In addition, if external force causes pipeline or other damage. At this time, cover the hole with cement to further ensure the safety of use.
Fifth, after the corrugated pipe is installed, the relevant staff should dismantle all kinds of auxiliary positioning components and related fasteners on the corrugated pipe as soon as possible. Moreover, it is necessary to adjust the limit device to a position that meets the requirements according to the specified design requirements, so as to help the pipeline play a better compensation ability under environmental conditions.
Editor's summary: Prestressed corrugated pipe is a new type of pore-forming material, which has good sealing and waterless permeability and is mainly used in cement structures. It can be seen that the prestressed corrugated pipe has a wide range of applications, and naturally many people buy it. However, the quality of prestressed corrugated pipe products on the market is uneven, and the prices are also different, so it is difficult for people to choose a product with high cost performance.
