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:Why does the cast iron pipe always run off when testing?
If the pipe is exposed for pressure test, you must add a pier, or else the fittings fly out. You are not surprised. At the same time, the pressure test before the ink tube to make full immersion bubble discharge clean, or a big easy gas pressure pipe explosion.
Q:Ductile iron pipes perennial bubbles in the water will rot it
From the hydraulic performance, because ductile pipe specifications generally refers to the inner diameter of PE pipe diameter specifications generally refers to the same specifications, because under the condition of ductile pipe can achieve greater runoff; from the installation and maintenance cost, ductile pipe have more favorable price. The inner wall of zinc spray, anti-corrosion materials such as cement mortar, ductile iron pipe perennial bubbles in the water will not be rotten.
Q:Advantages and disadvantages of ductile iron pipes?
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. So, the ball compressive strength of ductile iron pipe is much higher than that of cast iron pipes, buried in the ground, the car is not easy to be crushed.
Q:Can ductile iron pipes be installed outdoors?
Ductile iron pipes can be installed outdoors.
Q:How to analyze and judge the quality of ductile iron pipe
The most intuitive judgment ductile pipe quality is the ratio of the thickness of cement and iron, cement thick wall thicker tube quality is better, there are also some manufacturers of the pipe, thick wall pipe head cast iron part looks to be thick, but there is also a thin iron pipe, so the judge quality to open look inside, personally think that the highest price of the manufacturer is Jinan steel, Jinan Iron and steel because the pipe quality can reach the national standard K9, the price is also lower than the emerging, Saint Gobain and other major brands, as the water supply pipe K8 is no problem, but the price and quality aspects for the construction of which more importance.
Q:How can the ductile iron pipe elbow be fixed?
The utility model relates to a groove connecting pipe which has the function of sealing and sealing, and mainly comprises three parts: a sealing rubber ring, a clamping band and a locking bolt. The inner rubber sealing ring is arranged on the outer side of the connecting pipe and is matched with the pre rolling groove, and then the outer ring is buckled on the rubber ring, and then can be fastened with two bolts. Because of the special sealing structure design of the rubber sealing ring and the clamp hoop, the groove connecting piece has good sealing property, and the sealing property is enhanced correspondingly with the increase of the fluid pressure in the pipe.
Q:How can the old water pipe ductile iron pipe be opened with three flanges?
Cast iron pipe is not good then did not take the treatment is not good in the local search do you master plumbing to the scene to see the actual situation, some teachers have you unexpected strain interpretation way.
Q:The benefits of ductile iron castings
Nodular cast iron, is a kind of high strength cast iron material developed in 50s twentieth Century, its comprehensive performance is close to the steel, it is based on its excellent performance, has been successfully used in casting complex stress, strength, toughness and wear resistance requirements of the higher parts.
Q:Is there a kind of pipe called lined ductile iron pipe? Seeking manufacturers?
Yes, ductile pipe is divided into two kinds, one is the ductile cast iron pipe pipe socket (socket ductile pipe), which is mainly used for water supply system, namely the fire water, because of ductile iron pipe with pressure, 10kg, 12kg, 16kg. Pressure small price, a few cheaper, because pure in the production process of different, 1. sand mill 2. metal water cooling, like water, the basic is 16kg.
Q:Maximum pipe diameter of ductile iron pipe
Price even if it is not clear, you can consult the ball mill cast iron pipe manufacturers!
