In what fields are ductile iron pipes used?

Ductile iron pipes have become the core pipes in urban water supply, drainage, gas transmission and industrial fields with their excellent sealing, corrosion resistance and high strength, ensuring safe and stable operation. During installation, the pipe mouth must be strictly cleaned, the rubber ring must be processed and the lubricant must be evenly applied, and seamless connection must be achieved through precise jacking and insertion.
Application fields of ductile iron pipes
Water supply field: In urban water supply systems, ductile iron pipes are everywhere, from water plants to urban trunk water supply networks, and then to branch pipes entering communities. Its good sealing, corrosion resistance and high strength can ensure the safe and stable delivery of drinking water, and prevent water quality from being polluted during the transmission process. It is the core pipe material to ensure urban water supply.
Drainage field: Whether it is urban domestic sewage discharge or rainwater collection and discharge, ductile iron pipes can play an important role. It can withstand the erosion of sewage and the impact of water flow during drainage, ensure the smooth operation of the drainage system, and reduce the risk of urban waterlogging.
Gas transmission: Gas is flammable and explosive, and the safety requirements for the transmission pipeline are extremely high. Ductile iron pipes, with their high strength and reliable sealing performance, can withstand pressure fluctuations in gas transportation, prevent gas leakage, and provide safety for urban gas supply.

Industrial field: In chemical, metallurgical, petroleum, pharmaceutical and other industrial production, it is often necessary to transport various corrosive media or materials with pressure requirements. The corrosion resistance and high strength of ductile iron pipes make them widely used in these industrial pipeline systems.

How to connect and install ductile iron pipes?

Cleaning the pipe mouth: Carefully remove all debris in the socket and scrub it clean to ensure that there are no impurities at the interface to ensure the tightness of the connection.

Handling the rubber ring: Clean the adhesive on the rubber ring, bend the rubber ring into a "plum blossom" or "8" shape, install it into the socket groove, and then press along the entire rubber ring with your hand, or use a rubber hammer to compact it, so that the rubber ring is evenly stuck in the groove without warping or twisting.

Apply lubricant: Apply lubricant evenly on the inner surface of the rubber ring installed on the socket, and at the same time, apply lubricant evenly on the outer surface of the socket, except for the socket line, to reduce the friction during insertion and make the installation smoother.

Pipe lowering: According to the actual situation on site, use the manual pipe lowering method or the mechanical pipe lowering method to lower the pipe to the bottom of the groove as required.

Installation of machinery and equipment: Install the machinery and equipment required for installation in place. Be careful not to contaminate the cleaned pipe parts again during the installation process.

Push insertion: First put the socket into the socket, and press the socket onto the rubber ring in the socket, connect the wire rope and the fall chain, tighten the fall chain, and slowly insert the socket into the socket until it is fully in place. At this time, there should be a gap of about 2mm between the socket and the socket, and the distance from the outer edge of the socket to the rubber ring should be consistent.

Ductile iron pipes play an irreplaceable role in urban construction and industrial production with their unique performance advantages. With the continuous advancement of technology and the expansion of application areas, it is believed that ductile iron pipes will continue to shine in future infrastructure construction.
