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:DN1800 can the length of ductile iron pipes be several meters? What is the total weight?
Ductile cast iron pipe after annealing, the microstructure is ferrite and pearlite, good mechanical properties, excellent corrosion resistance, good ductility, good sealing effect, simple installation, mainly for municipal, industrial and mining enterprises, water supply, gas, oil etc..
Q:Does the cast iron have size 250? What's the performance?
You should be the casting grade or material, if it is ductile iron, said generally between QT400-15 or QT700-2 different indicators, said in front of the tensile strength, the elongation rate refers to the back, China is now the lowest grade of nodular cast iron material is QT400-15, such as QT250.In addition, the number 250 you refer to may also be a code name for ductile iron parts, such as 200, 300, etc., which are manufactured by the factory as required by the project.Gray iron, which has a 250 brand, is generally referred to as HT250, but it is not ductile iron.The machine on the ductile iron and gray iron are used, but generally not made of grey cast iron gear
Q:How can the connection of ductile iron pipe elbow be convenient for connecting?
Ductile cast iron pipe in the groove pipe connection technology is also called the lathedog connection technology, has become the most liquid and gas pipeline connection technology, although this technology is later than foreign in domestic development time, but because of its advanced technology, domestic market quickly received. Since 1998, it has been developed and applied in just a few years. It has gradually replaced two traditional ways of pipe connection, such as flange and welding. Not only technically more mature, the market is generally recognized, but also by the national laws and regulations actively guide the policy. The application of grooved pipe connection technology makes the complex pipe connection procedure simple, fast and convenient. Took a big step forward in pipeline connection technology.
Q:The plug connection DN800 ductile iron pipe has been installed. "Shall I think so?"
The main components of ductile iron pipes are carbon, silicon, manganese, sulfur, phosphorus and magnesium. Perform standard [span]GB/T13295-2003 ISO2531/2003
Q:Do ductile iron pipes have inner enamel?
If the market supply is indeed difficult, can be done by the owners, Design Institute of supplier relationship; if the design institute requires it to provide products can persist in wilfully and arbitrarily, the available information (if the market can not supply, design a hair ah).
Q:What is the difference between a cast iron pipe and a ductile iron pipe?
Nodular cast iron has high strength and strong plasticity. The tensile strength of ductile iron is twice that of gray iron, and the yield strength even exceeds that of cast steel.
Q:Deep well spiral iron pipe, or ductile iron tube?
Ductile weakness: ductile cast iron pipes connected by human factors such as the operation level of responsibility, influence, construction not convenient. The advantages of PE PE PE pipe has good corrosion resistance and its anti inorganic performance than that of the metal pipe is much stronger in the buried without corrosion, construction convenient. Small diameter PE pipe in the price performance ratio is better than that of steel and ductile iron.PE tube have disadvantages: benzene, gasoline, carbon tetrachloride and other organic solvents have certain effect on pe. If the organic solvent is infiltrated into the polyethylene, the swelling will occur, and its physical properties will be decreased. Its pressure resistance and temperature resistance are poor.
Q:Can cast iron pipes not be used for domestic water supply and drainage?
Cast iron pipes are mostly used in fire fighting, fire hydrant water supply and indoor water supply. Plastic pipes are used in general and high water riser pipes are made of plastic steel composite pipes
Q:What is the relationship between the mechanical properties of spheroidal graphite cast iron and its spheroidization rate?
The spheroidization level reflects only the final shape of graphite. The higher the spheroidization level of ductile iron is, the better its performance is, but this is not entirely the level of spheroidization to determine.The mechanical properties of nodular cast iron are closely related to its microstructure. Different grades of ductile iron require different mechanical properties such as tensile, yield, elongation, impact and hardness.
Q:What are the requirements for the hydrostatic test of ductile iron pipes?
The pipe work pressure P is less than 0.5MPa, the test pressure is 2P, the pipe work pressure is greater than 0.5MPa, the test pressure is P+0.5. After the water pressure rises to the test pressure, the pressure is fixed for 10 minutes, and the pipe joint and the pipe body are not damaged and leaked.
