5. FAQ:

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:What's the function of the cement mortar lining of ductile iron pipes?
Active protection is superior to barrier coating, cement mortar lining, and a stable hydroxide film formed on the surface of ductile iron and steel pipe to form a protective layer. This kind of protective coating has excellent antiseptic properties because they spontaneously protect themselves even in discontinuous linings. A polymer in sharp contrast, such as an epoxy lining, is also barrier coating, but only if 100% is applied without leakage. Any interruption or leakage will cause corrosion.It has been documented that cement mortar and cement mortar have been applied to the field of water transportation and can meet the water quality standards for a long time. Some standards still apply to the world. Cement mortar does not support microbial growth. In the case of corrosive water or low flow rate (prolonged stagnation), it is better to use cement mortar lined pipes because it can maintain high pH values in the pipe. This does not cause health problems and can be prevented by very simple sealed coating methods. The natural characteristics of the sealing coating provide the best protection for the inner wall of the pipe, while ensuring that all the water quality indexes meet the quality requirements, low cost and high efficiency.
Q:What does "K8" mean in ductile iron pipe grades?
K9 is GB, K10 is specially customized, K8... Strictly speaking, it is not up to standard, standard length, wall thickness and so on.. Many workshops, grades of factory products, such as K9, standard length 6.15M, K8 is 6M, wall thickness from the beginning of DN100, are thin on the point.
Q:What is cast iron pipe, specification for cast iron pipe?
A cast pipe made of cast iron. Cast iron pipes are used for water supply, drainage and gas transmission lines. They include cast iron pipes and pipe fittings.
Q:What is the minimum pipe diameter of cast iron pipe?
Cast iron pipe: cast pipe made of cast iron. 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.
Q:Ductile iron gears are generally treated without heat treatment
The mechanical properties of ductile iron are equivalent to quenched and tempered steel. The gears made of ductile iron can be quenched or tempered by high temperature + surface quenching, that is, quenching and tempering treatment + surface hardening.
Q:Does the cast iron pipe for spheroidal graphite need corrosion protection when laying underground?
Ductile iron pipe is a kind of cast iron pipe.
Q:The difference between flexible joint cast iron pipe and flexible anti-seismic cast iron pipe
The appendix is selected so that readers can understand the design, construction and other contents of the ductile iron pipe. This book can be used for the manufacture and application of ductile iron pipe in the field of scientific research personnel, designers, production personnel, construction personnel, management personnel to read.
Q:What do ductile iron pipes need to connect with three? Can I contact it directly?
The new process adopted at present is groove connection. With groove parts, of course, your ductile iron tube should also be grooved!
Q:The difference between cast iron pipe and ductile iron pipe
Cast iron pipes, also known as pig iron pipes, ordinary gray iron. Often used in socket connection, the sealing material is usually cement rigid interface.
Q:Method for cutting large diameter ductile iron pipe
When the volume ratio of oxygen and acetylene is less than 1, a carbonized flame is obtained. Because of less oxygen and incomplete combustion, the flame is longer than the neutral flame and the temperature is lower. Acetylene in the carbide flame is suitable for welding high carbon steel, cast iron and cemented carbide materials. When welding other materials with a carbide flame, the weld metal becomes hard and brittle.
