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 is the disadvantage of nodular cast iron in excess of silicon?
Silicon has a great influence on the performance of nodular cast iron. It mainly shows that silicon can refine graphite and improve the roundness of graphite ball.
Q:The role of chromium in nodular cast iron
In the bending fatigue test of crankshaft, it is also found that the chromium containing cast nodular iron crankshaft has the characteristics of large ultimate bending moment, high safety factor, overload duration, high strength and small deformation.
Q:Is it better to use steel tubes or ductile iron pipes for water supply?
Flexible seamless steel pipe is good toughness, good processing, better than ductile iron corrosion resistance, the price is slightly higher;
Q:Qianwei County ductile iron pipe which tool to use cutting convenience?
Cutting method for cutting ductile iron pipes, in order to obtain neat kerf, we should start with a direction of play saw saw to end. If the requirement of the section is not high, the direction of sawing can be changed gradually to reduce the resistance and facilitate cutting in.
Q:The difference between ductile iron pipe and UPVC drain pipe
Centrifugal ductile iron pipe is ideal for urban water supply, gas pipelines, sets of high strength, good ductility and corrosion resistance advantages, performance with nature, iron and steel, is the replacement of the traditional cast iron pipe and common steel pipe renewal;
Q:What does "K8" mean in ductile iron pipe grades?
1 ductile iron pipe grade K8, on behalf of the ductile iron 8 grades, K refers to the wall thickness coefficient, the higher the grade, the greater the pressure, the lower the level, the less pressure to bear.2 wall thickness calculation formula: e=K (0.5+0.001DN).
Q:What is cast iron pipe?
Cast iron pipes (Cast, Iron, Pipe), 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.
Q:Is nodular cast iron pipe filled with Yau Ma Tei?
The main components of ductile iron pipes are carbon, silicon, manganese, sulfur, phosphorus and magnesium. Perform standard [span]GB/T13295-2003 ISO2531/2003
Q:What's the difference between ductile iron pipe and cast iron pipe?
Ductile iron pipe is based on cast iron, changed some of the characteristics of the structure of iron, so that it has become a lot of toughness, than the cast iron pipe is too brittle shortcomings much better, the tensile strength of the pipe bending strength greatly improved. The sealing material used in the socket interface is rubber ring.
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!
