Q: How to control mortar proportioning in ductile iron pipe cement coating: The mix ratio of cement coated mortar for ductile iron pipes refers to the weight ratio of various raw materials consisting of ductile iron pipes and cement coated mortars.

Q: Can the underground cast iron pipes be connected with clamps to form buttress?: Best not to, because the use of clamp connection way to connect the poor integrity of the pipeline, the base treatment is not in place or uneven settlement, it is easy to produce deformation, resulting in pipe bending deformation, easily leaked from the junction.

Q: Are ductile iron pipes resistant to hydrogen sulfide corrosion?: Generally, ductile iron pipes exhibit resistance to hydrogen sulfide corrosion. Ductile iron, a form of cast iron treated with magnesium, results in a material that is both flexible and durable. This treatment considerably improves its resistance to corrosion, including corrosion caused by hydrogen sulfide. The magnesium within the ductile iron creates a protective layer on the surface, preventing the infiltration of hydrogen sulfide and other corrosive substances. Nonetheless, it is important to acknowledge that the resistance of ductile iron pipes to hydrogen sulfide corrosion can still be affected by factors such as the concentration and duration of exposure to the corrosive environment. Hence, it is crucial to implement proper maintenance, regular inspection, and appropriate protective measures to ensure the long-term durability and performance of ductile iron pipes in the presence of hydrogen sulfide.

Q: How do we handle the leaking of the ductile iron pipe?: If it is installed in the pipeline, test pressure leakage, glue can be repaired and then welded, usually with hoop.

Q: How can the old water pipe ductile iron pipe be opened with three flanges?: There are finished products with flanges, but they are not easy to buy. They are basically useless. Now basically the adoption of the pipe, so it is recommended to use the tray flange, disk plug: one for the flange, one for the socket; socket: one for the mouth, one for the socket. According to the diameter of pipe fittings, there are usually equal diameter three pass, different diameter three pass and so on. According to the direction of branch pipe, there are three straight and oblique three. In accordance with the connection mode, there are three ordinary, threaded three pass, card sleeve three, and socket three. The connecting flange of the sleeve is connected with the connecting angle of the bearing mouth, and the telescopic device can also be used. The connection between the pipe and the pipe adopts the form of socket type or flange disk interface. According to the function, it can be divided into two kinds: flexible interface and rigid interface. The flexible interface is sealed with rubber ring, which allows a certain degree of corner and displacement, so it has good seismic resistance and tightness, and it is easy and quick to install than rigid interface.

Q: Can ductile iron pipes be used for bridge crossings?: Ductile iron pipes are indeed suitable for bridge crossings. This material is widely used in various applications, such as water and wastewater systems, due to its strength and durability. When it comes to bridge crossings, ductile iron pipes offer numerous advantages. They possess high tensile strength, enabling them to handle the load and stress imposed by the bridge structure. In addition, they are highly resistant to corrosion, making them well-suited for environments where bridges may be exposed to moisture and other harsh conditions. Moreover, ductile iron pipes have the capability to withstand seismic activity, making them a dependable choice for areas prone to earthquakes. Overall, ductile iron pipes are a reliable and appropriate option for bridge crossings due to their strength, durability, resistance to corrosion, and ability to withstand seismic activity.

Q: How can stainless steel pipes and ductile iron pipes be joined?: Or with a gland type expansion joint, by tightening the pressure plate bolts, sealing pipe fittings and pipe wall, so as to achieve sealing, while retractable function

Q: Can ductile iron pipes be used for underground river crossings?: Yes, ductile iron pipes can be used for underground river crossings. Ductile iron pipes are known for their strength and durability, making them suitable for various applications including underground river crossings. These pipes have a high tensile strength and can withstand the external loads and pressures exerted by the surrounding soil and water. Additionally, they have excellent corrosion resistance, which is crucial when dealing with underground water sources like rivers. Ductile iron pipes are also capable of withstanding ground movements, settling, and other geological challenges that may occur during the installation and operation of underground river crossings. Therefore, they are a reliable choice for ensuring the safe and efficient transportation of water across rivers while maintaining the integrity of the underground infrastructure.

Q: The plug connection DN800 ductile iron pipe has been installed. "Shall I think so?": Ductile iron pipes are defined as pipes made by casting more than 18 of casting molten iron by adding a spheroidal agent and then centrifugally centrifugally cast by a centrifugal nodular cast iron machineDuctile iron pipe ([span]Ductile Cast Iron Pipes), referred to as ball pipe, ductile iron pipe and ductile iron pipe etc..

Q: Advantages and disadvantages of ductile iron pipes?: Ductile iron pipes are widely used for municipal water supply and drainage, rural drinking water and outdoor fire fighting works; mechanisms; cast iron pipes; main use; municipal high water drainage.
