Full range of specifications for bridge longitudinal drainage pipes and steel drainage pipes

Steel drain pipes are made of high-density steel and other additives. The size of the pipe holes can range from 10mm x 1mm to 30mm x 3mm, available in 360-degree, 270-degree, and 180-degree configurations. Axial cast iron drain pipes are primarily made from resin, with appropriate additives, and then extruded or molded into plastic products.

Steel Drain Pipe

The bridge steel drainage pipes are composed of steel tube materials made from high-density steel and other additives; during the production of cast iron drainage pipes, the wall thickness of the castings must be uniform to avoid affecting the strength and hardness of the castings, and are suitable for paving layouts with waterproofing layers. The inner diameter of the drainage pipes is usually 0.10 to 0.15 meters, and the lower end of the pipe should extend below the surface of the carriageway slab by at least 0.15 to 0.20 meters to prevent moisture from seeping into the main beam rib surface. The pipe body is smooth, free of sand holes, and has a long service life, making it the primary choice for highway and railway drainage systems.

The advantages of steel drainage pipes: lightweight, easy to handle and transport; cast iron drainage pipes are also lightweight, making handling, loading, unloading, and construction more convenient, saving on labor costs. Excellent chemical resistance: cast iron drainage pipes possess excellent resistance to acids, alkalis, and corrosion, making them highly suitable for use in the chemical industry.
