Hangzhou Drain Pipe - Cast Iron Drain Pipe Casting Process

Description :

　　The casting process of cast iron drain pipe - review the drawings according to the drawings - make the model according to the drawings - check the model according to the drawings after making it - have a model master confirm whether it is correct - after confirming that it is correct and intact, dry it - after the model is dry, brush the coating for 3 to 5 times. The coating should be dried carefully every time to ensure the qualification rate of the finished product.

　　Cast iron drain pipe; The next step is to pack the goods, which will be completed by experienced craftsmen with many years of experience. When the waiting time is up, the casting can be completed. After casting, it also takes about 8 hours to come out. After the cast iron drain pipe comes out, it can be polished and sandblasted to see the finished cast iron drain pipe.

　　1. The appearance of the drainage pipe is beautiful, elegant, smooth, and has a small coefficient. The pipeline is corrosion-resistant, wear-resistant, and does not scale. It has high fluid resistance, fluid transport efficiency, and noise reduction. It has the advantages of high impact strength, high mechanical performance, good toughness, and strong bending ability. It is particularly suitable for the construction and use of drainage pipes for roads and railways. 2. It has a wide temperature range, good weather resistance, and good dimensional stability when the temperature changes. It is lightweight, low in price, easy to transport, install, maintain, and maintain. It is mainly used in railway bridge drainage, aquaculture, agricultural drainage, irrigation, electrical engineering, and chemical sewage systems. Cast iron drainage pipes have good low noise, high strength, and long life. Graphite in cast iron can buffer vibration. The transfer of vibrational energy between grains and the conversion of vibrational energy into thermal energy.

　　Product overview PVC drain pipe for bridge is a plastic product extruded or injection molded with resin as the main raw material, adding appropriate additives. The pipe has many characteristics, such as tasteless, anti-corrosion, aging resistance, good weather resistance, etc. It can be widely used in buried or surface water supply pipes. It has sufficient strength and ring stiffness to withstand various underground loads. It is easy to transport, lay and install. It is an ideal product to replace galvanized steel pipes, cast iron pipes, and cement pipes.

　　key technology

　　1. The construction of the drainage pipe should be carried out according to the design requirements. The drainage pipe should extend no less than 30mm from the bottom of the structure, and the longitudinal spacing should not exceed 4m.

　　2. For overpasses and bridges on highways, the drainage pipes should not be directly hung under the slab. The drainage pipes can be directly led to the ground through longitudinal and vertical drainage pipes, or executed according to design requirements, and the pipes should have good fixing devices, such as anchor rails and clamps and other embedded parts.

　　Innovation

　　1. The appearance is beautiful and elegant, smooth, with a small coefficient. The pipeline is corrosion-resistant, wear-resistant, and does not scale. It also reduces fluid resistance, fluid transport efficiency, and noise. It has the advantages of high impact strength, high mechanical properties, good toughness, and strong bending resistance, which solves the problem of crushing during construction and use. Especially suitable for drainage pipes on 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.
