1. Introduction
In the field of modern engineering, ductile iron has become the preferred material for many projects with its unique performance advantages. Among the many ductile iron products, dinsen ductile iron pipes have won the favor and recognition of customers from all over the world with their high quality and efficient production cycle. This article will explore the application areas and installation methods of ductile iron in depth, and at the same time demonstrate the excellent quality of dinsen ductile iron pipes.
2. Characteristics of ductile iron
Ductile iron is a high-strength cast iron material. Through a special treatment process, graphite is distributed in a spherical shape in the metal matrix. This structure gives ductile iron many excellent properties:
High strength: Ductile iron has high tensile strength and yield strength, and can withstand greater pressure and load.
Good toughness: Compared with ordinary cast iron, ductile iron has better toughness and is not prone to brittle fracture.
Corrosion resistance: It has good resistance to a variety of corrosive media and prolongs its service life.
Good machinability: It can be made into products of different shapes and sizes through various processing methods.
3. Application of ductile iron
3.1Water supply and drainage field
Ductile iron pipes have been widely used in water supply and drainage projects. Its corrosion resistance, high strength and good sealing ensure the safety and reliability of water supply and drainage. Dinsen ductile iron pipes have become the first choice for many urban water supply and drainage systems with its high quality.
In sewage treatment plants, ductile iron pipes are also used to transport sewage and sludge, and their corrosion resistance can effectively resist the erosion of chemicals in sewage.
3.2 Municipal engineering
In urban road and bridge construction, ductile iron manhole covers and rainwater grates are widely used. They have the characteristics of high strength, corrosion resistance and anti-slip, and can withstand the heavy pressure of vehicles and pedestrians.
Ductile iron is also used to make municipal facilities such as street light poles and traffic sign poles. Its good machinability and weather resistance make it perform well in outdoor environments.
3.3 Industrial field
In industrial fields such as petroleum, chemical industry, and electric power, ductile iron pipes are used to transport various media such as crude oil, natural gas, steam, etc. Its corrosion resistance and high strength characteristics can meet the strict requirements of industrial production.
Ductile iron is also used to manufacture mechanical parts, such as gears, crankshafts, connecting rods, etc. Its good mechanical properties and machinability make these parts play an important role in mechanical equipment.

5. Installation method of ductile iron pipes
Preparation work
Before installing ductile iron pipes, the construction site needs to be cleaned to ensure that the site is flat and free of obstacles.
According to the design requirements, determine the laying route and slope of the pipeline, and measure and lay out the lines.
Prepare the tools and materials required for installation, such as cranes, electric welders, rubber sealing rings, etc.
Pipeline connection
There are two main ways to connect ductile iron pipes: socket connection and flange connection. Socket connection is to insert the socket of one pipe into the socket of another pipe, and then seal it with a rubber sealing ring. Flange connection is to connect two pipes together through a flange, and then tighten them with bolts.
When connecting pipes, it is necessary to ensure that the center lines of the pipes are aligned, the gaps between the sockets and the sockets are uniform, and the rubber sealing rings are installed correctly.
Pipeline laying
When laying the pipeline, a crane is needed to slowly place the pipeline into the trench to avoid collision between the pipeline and the trench wall.
After the pipeline is laid, the pipeline needs to be adjusted to ensure that the slope and center line of the pipeline meet the design requirements.
Then, the pipeline is fixed to prevent displacement during use.
Pipeline pressure test
After the pipeline is installed, the pipeline needs to be pressure tested to check the tightness and strength of the pipeline. During the pressure test, the pipeline needs to be filled with water and then the pressure is gradually increased until it reaches 1.5 times the design pressure.
During the pressure test, the pipeline needs to be inspected to observe whether there is leakage and deformation. If problems
