　　How to define a rectangular cast iron drain pipe?

　　There are two main definitions for rectangular cast iron drain pipes, which will be explained to you one by one.

　　Definition of rectangular cast iron drain pipe 1: It is mainly used for railway bridge drainage, bridge guardrail supports on both sides of highways, and engineering and chemical sewage systems.

　　Definition of rectangular cast iron drain pipe 2: a. The construction of the drain pipe should be carried out according to the design requirements, and the drain pipe should protrude from the bottom of the structure by not less than 30mm, with a longitudinal spacing of not more than 4m. b. For bridges on overpasses and highways, the drain pipe should not be directly hung under the slab, and can be directly led to the ground through longitudinal and vertical drainage pipes.

　　Rectangular cast iron drainage pipes are mainly responsible for rainwater and highway drainage tasks. Rectangular cast iron drain pipe, suitable for paving structures with waterproof layers. The inner diameter of the drainage pipe is generally 0.10-0.15m, and the lower end of the pipe should extend at least 0.15-0.20m below the bottom of the roadway slab to prevent moisture from seeping into the surface of the main beam rib. The pipe body is smooth, free of sand holes, and has a long service life. It is an ideal product for drainage systems on highways and railways.

　　Compared to the domestic PVC pipe market situation, domestic plastic pipe products have price advantages in the international market, are increasingly valued, and have relatively high profits. According to a research report by a German research company, the global market value of plastic pipes is expected to reach 80 billion US dollars by 2019. In 2011, plastic pipes made from PVC accounted for over 55% of the total production Next is PE, especially HDPE, which accounts for 28% of the remaining 45% Experts say that although traditional materials are still popular among the public, the proportion of materials such as ABS, PB, PA, etc. in future pipe production will continue to increase.

　　In recent years, with the rapid development of urbanization in China, the "Western Development", "West East Gas Pipeline", "South to North Water Diversion", as well as the construction of the national highway network, railway network, residential construction, etc., have all opened up unprecedented markets for PE pipes; The increasing demand for various agricultural plastic water-saving irrigation equipment has provided historical opportunities for the development of PE pipes in China.

　　Since entering 2013, the demand for plastic pipes in China has continued to grow slightly, and the overall performance has been better than in 2012. On the one hand, it is driven by the investment and construction of infrastructure projects; On the other hand, the speed of industry integration is accelerating, and some smaller enterprises without resource advantages and innovation are being eliminated at an accelerated pace. Some PE pipe manufacturers with good product quality and large scale are constantly introducing new technologies and innovating for development; In addition, since entering 2013, the price of raw material PE has continued to consolidate at a low level, and the production cost of PE pipes is controllable and profitable. In special times, plastic pipe companies across the country must have a sense of social responsibility and not only pursue immediate benefits. To improve overall standards, they must reject counterfeit and inferior pipes.
