5.FAQ:
We have organized several common questions for our clients,may help you sincerely:
1.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.

2.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.

Q:Will the cast iron pipes rust?
Qualified ductile iron pipe requires lining standard cement. The outer wall of pipe needs spraying zinc treatment and asphalt paint coating, and other epoxy resin paint can also be selected.
Q:What is the disadvantage of nodular cast iron in excess of silicon?
Therefore, the increase of silicon content in nodular iron greatly improves the strength index and reduces toughness. Ductile iron has a greater crystalline undercooling and a tendency to chill when treated by spheroidizing, and silicon reduces this tendency.
Q:What quota can be used for the installation of DN300 ductile iron pipes?
Ductile iron quota, to see what works, such as the use of ductile cast iron bridge, to see the river length, through traffic, perennial water level to determine the ductile iron pipe length, diameter and number;
Q:How can the ductile iron pipe be tested?
In the hydraulic test, the ductile iron pipe can not be close to the back, support, pipe end and so on. The inspection must be carried out after all stops
Q:Can the underground cast iron pipes be connected with clamps to form buttress?
The hoop has the advantages of beautiful appearance, convenient operation, strong clamping force, good sealing performance, etc.. Mainly used for connecting and fastening vehicle, ship, diesel engine, gasoline engine, machine tools, fire, and other machinery and equipment, chemical equipment general nylon hose, plastic hose, hose cloth, water interface and seal etc..
Q:What are the differences between ductile cast iron pipes and centrifugal ductile iron pipes?
Small, thin pipe fittings are usually rolled or continuously cast, and large, thick pipes are usually centrifugally cast. Compared to sand casting, the tissue is compact and homogeneous.
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:What are the advantages of cast iron pipes?
The ductile iron pipe with flexible joint construction, convenient operation, can improve the efficiency of construction, improve the construction conditions, reduce the construction cost, and most of the rubber ring connection interface, simple operation, can shorten the construction period, reduce the construction cost.
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:What is the excavation width of ductile iron pipes with diameters greater than 1400?
When the condition does not allow enough slope, it is necessary to do wall protection and other means to ensure safetyRemind me, such a big pipe, dig deep in two ways. One is the depth diameter (range at the junction of 1.6 m in length and 500 for manholes and operation. The lower bolt assembly when) there is a depth diameter plus 500. and then in the trench laying branch the pier, installed after the fine stone tamped backfill.Can also be buried directly with the pipe diameter, and then put into the assembly. This method requires a large space on the ground, otherwise, the volume is too large after assembly, weight is too heavy, may cause damage to the pipeline and personnel injuries
