We have organized several common questions for our clients,may help you sincerely:

1.Q: Why would you choose ductile iron pipe rather than other pipe materials?
   A:The reasons are obvious for that not only ductile iron pipe possesses the inherent strength and flexibility of ductile iron, combined with proven corrosion protection systems, but also the cost savings can be achieved from design to installation and commissioning.
2.Q:Why can you guarantee the inner of pipes can’t be corroded?
   A: High alumina cement mortar lining and sulphate-resistant cement mortar lining. These two special linings are applicable to inner anti-corrosion for sewage pipes, improving resistance to erosion of the sewage components.

Q:Is the fire hose capable of using rapid repair joints?
Installation joint. Insert the socket into the socket to coincide with the central axis of the pipe or pipe to be joined. Use a guide chain to tighten the pipe member until the pipe mouth enters between the two white lines.
Q:Can the sealing ring of ductile iron pipe be reused?
It is better not to have used things, easy aging, sealed, the best to use new
Q:What pipe can be used to replace the cast iron pipe in the water supply? Thank you
You are mistaken in concept. The cast iron pipe is the sort of connection method. The ductile iron pipe is classified according to the material.
Q:What is cast iron pipe?
According to its manufacturing methods can be divided into: sand, centrifugal pipe, straight pipe, continuous cast iron pipe and sand pipe.According to the material used, it can be divided into gray iron pipe, nodular cast iron pipe and high silicon iron pipe.
Q:What is the relationship between the direction of the spigot and the direction of the flow in the ductile iron pipe?
The utility model is mainly used for conveying water, and is an ideal choice for tap water pipes.
Q:What are the specifications of cast iron pipes?
To be divided into: cast cast pipe. Cast iron pipes are used for water supply, drainage and gas transmission lines. They include cast iron pipes and pipe fittings. Labor intensity is small. According to the casting method, it is divided into continuous cast iron pipe and centrifugal cast iron pipe, in which the centrifugal cast iron pipe is divided into sand mould and metal type two kinds. Divided into gray cast iron pipe and nodular cast iron pipe according to different material. Rubber ring seals for flexible interfaces,
Q:How do we handle the leaking of the ductile iron pipe?
A hoop is a component that holds or ties another material with one material. It belongs to the fastener. The hoop holding device is composed of a hoop plate, a wing plate, a tension tie plate, a bolt and an inner liner. There are many kinds of hoop, hoop cable, wire rod hoop, hoop cable, wire hoop, stainless steel hoop are commonly used.
Q:Ductile iron pipe is flexible pipe or rigid pipe
The flexible tube and you say should refer to the common steel pipe and seamless steel pipe, because the two are by the simple method according to the needs and the deformation, in other words, ductile iron is cast out without deformation.
Q:QT400-10 nodular cast iron requires hardness of HRC47~51. Why can't quench hardness be reached?
Quenching temperature: when the silicon content of nodular cast iron is 2.0-3.0%, the quenching temperature is 860-900 DEG C, the silicon content is low, and the upper limit is taken when the lower limit is high.2. holding time: because of the consideration of diffusion graphite cast iron, alloy steel is therefore the holding time, holding time longer than carbon steel.3. oil quenching.
Q:What's the difference between cast iron pipe and steel pipe?
Steel pipe is not only used to transport fluid and powder solid, exchange heat energy, and manufacture mechanical parts and containers, but also is an economic steel. It can reduce weight and save 20 to 40% of metal by using steel pipe to make building structure, network frame, prop and mechanical support. Moreover, it can realize factory mechanization construction. Using steel pipe to manufacture road bridge can not only save steel, simplify construction, but also greatly reduce the area of coating protective layer, save investment and maintenance cost.
