, Introduction
Metal corrugated pipes are made of different metal materials due to their different uses. Because of their different materials, the properties and uses of the processed metal bellows are also different.
, Prestressed metal corrugated pipe product performance:
, Anti-permeability test: There will be no water or slurry leakage for 3 minutes when filled with water or cement slurry with a water-cement ratio of .
Rigidity test: radial deformation when resisting concentrated load or uniform load.
Tensile test: There is no damage to the pipe wall under axial tension.
Bending resistance test: When the bending degree is 3 times the radius of curvature, there will be no water or slurry leakage. , Pull-out resistance test: The pull-out resistance buried in concrete is more than 3 times the design pull-out strength of the anchor bolts.
Technical advantages:
High strength: The strength of metal corrugated culverts is ~3 times that of cement pipes.
. Light weight: metal corrugated culverts are only /~/ of cement pipes of the same specifications.
Long life: The service life of metal corrugated culverts is more than 10 years.
Cost reduction: When the metal corrugated culvert spans (diameter), the larger the span, the more obvious the benefit.
Convenient and fast construction: Metal corrugated culverts do not require large machinery on site and only require a small amount of manual operations.
, Product Structure
Metal corrugated pipe is mainly composed of a corrugated pipe part and a matching connection part at both ends (it is processed and formed in one time).
The metal bellows are reasonably priced and sold to Shanghai, Beijing, Guangzhou, Shenzhen, Urumqi, Lanzhou and other places. They are also sold to Suzhou, Wuxi, Nanjing, Nantong, Changzhou, Xuzhou, Yancheng, Yangzhou, Taizhou, Zhenjiang, Wuhu, Tianjin, Hangzhou, Chongqing, Wuhan, Shenyang , Nanjing, Chengdu, Zhengzhou, Jinan, Changsha, Shijiazhuang, Harbin, Changchun, Fuzhou, Xi'an, Nanchang, Hefei, Kunming, Taiyuan, Nanning, Ma'anshan, Huaibei, Lu'an, Chaohu, Xuancheng, Bengbu, Anqing, Huainan, Tongling , Chuzhou, Fuyang and other places.
The metal corrugated pipes produced by Hengshui Hengguang Engineering Rubber and Plastic Co., Ltd. are divided into round pipes and flat pipes from the beginning. In terms of processing methods, they are galvanized and non-galvanized. In terms of caliber, there are There are two types: general caliber and large caliber pre-embedded. Due to different specifications and processing techniques, the uses are also different. Our company has more than ten years of production experience. The materials are all made of high-quality steel strips and are of high quality. The quality of the prestressed metal corrugated pipes (prestressed metal spiral pipes) produced by our company meets the requirements of the Ministry of Transportation industry standard "Metal Corrugated Pipes for Prestressed Concrete Bridges" and has been widely used in road bridges, railway bridges, construction water conservancy, and electric power and other national key projects.
