Quzhou Drainage Pipe Manufacturer - Advantages of Cast Iron Drainage Pipes

Description :

　　Quzhou Drain Pipe Manufacturer - Advantages of Cast Iron Drain Pipe - Circular Drain Pipe with a horn mouth diameter of 215mm, inner diameter of 161mm, lower mouth inner diameter of 100mm, total length of 420mm, pipe length of 320mm, steel sleeve and grille cover totaling 10mm. The individual weight ranges from 8kg to 18kg, so the price of circular drain pipe varies between 60-80 yuan; The commonly used rectangular drain pipe has an outer diameter of 170mm and an inner diameter of 140mm. The lower outlet has an inner diameter of 100mm and a total length of 600mm. It is a manufacturer of cast iron drain pipes and bridge drain pipes.

　　Our company's products have been successively used in railway, highway, highway, bridge, and water conservancy engineering projects. We have achieved good evaluations in cooperation with multiple engineering units. The waterproof layer paving structure of cast iron drain pipe. Cast iron drain pipe is suitable for paving structures with waterproof layer The inner diameter of the drain 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 purpose of the cast iron drain pipe is to prevent seepage.

　　The annealing process for cast iron drain pipes is: heating to 550-950 ℃ for 2-5 hours, followed by furnace cooling to 500-550 ℃ and then air cooling out of the furnace. During the high-temperature insulation period, the high permeability carbon body and eutectic secondary carbide and eutectoid carbide also decompose and undergo graphitization process. Because infiltration improves the mechanical properties of castings. Sometimes normalizing is also a preparation for surface quenching of ductile iron in the structure. Normalization can be divided into high temperature normalizing and low temperature normalizing.

　　1. The appearance is beautiful and elegant, the inner wall is smooth, the friction coefficient is small, the inner wall of the pipeline is corrosion-resistant, wear-resistant, and does not scale, reducing the frictional resistance of the fluid, improving the efficiency of fluid transportation, and reducing noise It has the advantages of high impact strength, high mechanical properties, good toughness, and strong bending resistance, reducing the problem of breakage during construction and use Especially suitable for drainage pipes in airports, roads, and railways.

　　2. It has a wide temperature range, good weather resistance, and good dimensional stability when the temperature changes Lightweight, low price, easy to transport, install, maintain and upkeep Mainly used in railway bridge drainage, aquaculture, agricultural irrigation and drainage, electrical engineering, and chemical wastewater discharge systems Mainly used for railway bridge drainage, guardrail supports on both sides of highways, engineering and chemical sewage systems.
