Yibin supplies cast iron drainage pipes for bridges, with a full range of specifications for drainage pipes

Description :

　　Drainage pipes are generally divided into cast iron drainage pipes, PVC drainage pipes, bridge drainage pipes, and bridge deck drainage pipes; Mostly used for vertical and horizontal drainage on the back of various retaining walls and side ditches on highways; Municipal engineering, water treatment plants, sewage treatment plants, garbage dumps, and other water supply and drainage systems are easy to install, with guaranteed quality, beautiful and elegant appearance, smooth inner walls, low friction coefficient, corrosion-resistant and wear-resistant inner walls of pipelines, no scaling, reducing fluid friction resistance, improving fluid transportation efficiency, and reducing noise.

　　And with a wide temperature range, compared to other drainage pipes of the same diameter, its price is lower; The orifice is located in the valley, and due to the bidirectional interaction between the wave crest and the filtering fabric, the orifice is not easily blocked, ensuring the smooth flow of the permeable system.

　　The weight of a bridge drain pipe depends on its diameter and length. Generally, a drain pipe with an inner diameter of 10cm and a wall thickness of 2mm weighs 5kg per linear meter. Commonly used bridge drain pipes have a wall thickness of 5-7 and varying diameters,

　　The upper diameter ranges from 265mm, 215mm, and 200mm, while the lower diameter ranges from 150mm, 100mm, and 90mm; The bidirectional effect of the filter fabric ensures that the holes are not easily blocked, ensuring the smooth flow of the permeable system.Compared with other drainage pipes of the same diameter, it has a lower price and corrosion resistance. Bridge drainage pipes, soft permeable pipes, and plastic blind ditches have become the three main products in China's civil engineering construction (seepage and drainage). Cast iron drain pipes are suitable for paving structures with waterproof layers. The pipe body should be lubricated, free of sand holes, and have a long service life, making it a good choice for drainage systems. Compared to soft spring drainage pipes, plastic is less prone to rusting.

　　Drainage pipe: English name: drainage pipe. Common types include PVC drainage pipe, bridge drainage pipe, cast iron drainage pipe, etc. Below, let me analyze the comparison between cast iron drain pipes and bridge drain pipes:

　　Cast iron drain pipe is an external steel pipe formed by adding other additives to high-density steel. According to different drainage requirements, the size of the pipe hole can be 10mm × 1mm-30mm × 3mm, and it can be evenly distributed in the range of 360 degrees, 270 degrees, 180 degrees, 90 degrees, etc; The bridge drain pipe is a plastic product that is extruded or molded with resin as the main raw material, added with appropriate additives. The pipe has many characteristics such as non-toxic, tasteless, anti-corrosion, anti-aging, and good weather resistance.

　　Cast iron drainage pipes are widely used in drainage fields such as highways, railway subgrades, subway engineering, waste landfills, tunnels, green belts, sports fields, and slope protection caused by high water content, as well as underground irrigation and drainage systems in agriculture and horticulture. It has become one of the three main products in China's civil engineering construction (seepage and drainage) along with soft permeable pipes and plastic blind ditches; Bridge drainage pipes can be widely used in bridge drainage, buried or surface water supply pipelines. They have sufficient strength and ring stiffness to withstand various underground loads, and are easy to transport, lay and install. They are an ideal product to replace galvanized steel pipes, cast iron pipes and cement pipes.
