Horizontal directional drilling involves drilling a pilot hole underground and then pulling the pipe through the hole. Jacking is a method where the pipe is pushed into the ground using hydraulic jacks.

Q: What is the exterior anticorrosion of nodular cast iron pipes?: First clean the impurity on the surface of the pipe or fitting, and then sprayed zinc treatment (130g/m and asphalt paint coating fand) not less than 70 m

Q: Principles for the antiseptic treatment of ductile iron pipes: 4. epoxy ceramic liningEpoxy ceramic lining is suitable for sewage pipes and gas pipelines, but because of its difficult manufacturing process and high cost, it has some limitations in its use. Epoxy ceramic lining has a high adhesion and finish. It is an excellent anti-corrosion coating.5. aluminate cement coating or sulphate cement coatingThese two special cement coatings are suitable for internal corrosion protection of nodular iron pipes used in sewage pipes to improve the corrosion resistance of acid and alkali components in sewage.

Q: Can ductile iron pipes be used in areas with high soil salinity?: Yes, ductile iron pipes can be used in areas with high soil salinity. Ductile iron pipes have excellent corrosion resistance and are often used for underground applications, including in areas with high soil salinity. The pipes are specially coated to prevent corrosion and are known for their durability and long service life, making them suitable for such environments.

Q: How does ductile iron pipe resist internal corrosion?: Ductile iron pipe resists internal corrosion due to the protective barrier formed by its cement lining. This lining acts as a barrier between the iron pipe and the transported fluid, preventing direct contact and minimizing the chances of corrosion. Additionally, the high carbon content in ductile iron enhances its corrosion resistance compared to other types of iron pipes.

Q: How does ductile iron pipe perform in high-velocity flow conditions?: Ductile iron pipe performs exceptionally well in high-velocity flow conditions. Due to its unique properties, including high tensile strength and impact resistance, ductile iron pipe can withstand the forces exerted by high-velocity flows without experiencing significant damage or failure. One of the key advantages of ductile iron pipe is its ability to resist the effects of water hammer, which is a sudden increase in pressure caused by the rapid deceleration or change in direction of water flow. This is particularly important in high-velocity flow conditions where the velocity of water is significantly higher than normal. Ductile iron pipes are designed to absorb and dissipate the energy generated by water hammer, preventing potential damage to the pipe and the surrounding infrastructure. Additionally, ductile iron pipe has excellent flow characteristics, allowing for smooth and efficient water transport even at high velocities. This is crucial in applications where a large volume of water needs to be transported quickly, such as in industrial processes or fire protection systems. The smooth interior surface of ductile iron pipe minimizes friction and pressure losses, ensuring that the water can flow freely and efficiently, reducing energy consumption and operating costs. Moreover, ductile iron pipe is highly resistant to corrosion, which is a common issue in high-velocity flow conditions where the water may contain aggressive chemicals or particulates. The protective lining and coating systems used in ductile iron pipes provide a barrier against corrosion, extending the lifespan of the pipe and maintaining its structural integrity. In summary, ductile iron pipe is well-suited for high-velocity flow conditions due to its ability to withstand water hammer, its excellent flow characteristics, and its resistance to corrosion. Its strength, durability, and reliable performance make it a preferred choice for various applications, ensuring efficient water transport even in demanding environments.
