Cast Iron Pipe is made of magnesium or rare earth magnesium combined with gold spheroidizing agent added to the molten iron before pouring, so that the pipe has the advantages of high strength, high elongation, impact resistance, corrosion resistance, and good sealing. The inner wall is lined with cement mortar. It improves the water transport environment of the pipeline, increases the water supply capacity, and reduces the energy consumption; the nozzle adopts a flexible interface, and the pipe itself has a larger elongation rate, which makes the pipeline flexible and can be compared with the surrounding pipeline in the buried pipeline. The soil works together to improve the stress state of the pipeline, thereby improving the reliability of the pipeline network operation. Therefore, the current water supply industry in my country usually uses ductile iron pipes as main pipes.
Iron Pipe
1. The inner and outer surfaces of cast iron pipe fittings must be smooth and clean, and no obvious defects such as cracks, cold partitions, wrong boxes, etc., which hinder use, are allowed. Local defects that reduce the wall thickness are allowed, but the depth shall not exceed (2+0.05T)mm Where T is the wall thickness of the tube.
2. The spare outline of the cast iron pipe fitting flange is clear, and no casting defects affecting the use are allowed.
3. With the consent of the purchaser, local defects that do not affect the use can be repaired, but the Repaired Pipe must be tested for water pressure or air tightness again.
Strong corrosion resistance, good compression and bending resistance, convenient joints, no peculiar smell and no harm to health, etc.
1. Since the cast iron pipe fittings use flexible joints, the construction operation is more convenient, which can improve construction efficiency, improve construction conditions, and reduce construction costs, and most of the interfaces are connected by aprons, which is easy to operate, can shorten the construction period and reduce the construction cost.
2. Cast iron pipe fittings have the advantages of withstanding high water supply pressure, resistance to external loads and adapting to changes in geological conditions. The pipe has the advantages of high strength, good toughness, corrosion resistance, easy installation of flexible interfaces, strong earthquake resistance, and low labor intensity. It can be applied to Sections with poor geology and crossing highways do not require additional processing of steel pipes, and with strong corrosion resistance, they can be applied to coastal and saline-alkali zones. It is widely used in underground pipeline engineering. Large-scale pipeline installation projects can better reflect its advantages of convenient installation and low labor intensity.
3 Cast iron pipe fittings have good sealing performance and are not easy to leak, which can reduce the leakage rate of the pipe network and reduce the daily maintenance cost of the pipe network.
