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:It's not easy to drill ductile iron with cobalt high speed steel bit. Please help to point it out
Choose carbide or whole carbide drill, about 90HRC in hardness. But it requires a high number of drills, around 3000.
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:Which is good for water polo cast iron pipe steel pipe?
Flexible seamless steel pipe is good toughness, good processing, better than ductile iron corrosion resistance, the price is slightly higher;
Q:How can the ductile iron pipes be treated with corrosion protection?
Epoxy coal tar coatingThe epoxy coal tar coating is not only suitable for gas pipelines, but also for sewage pipes. It is a two component coating with a high adhesion and a very smooth surface
Q:Advantages and disadvantages of ductile iron pipes
The ductile iron pipe is widely used not only in foreign countries, and has also been in the country to promote the use of good, in many areas of our country, ductile iron pipe has been widely used in medium and small diameter water supply pipe; compare the performance of ductile iron pipe and steel pipe: steel pipe can be divided into seamed steel pipe and seamless in the water supply pipe, commonly used in welded tube. Compared with ductile iron pipes, the steel tube has the advantages of good toughness, high tensile strength, thin tube wall, high pressure resistance, long pipes and less interfaces. The biggest drawback is that the corrosion resistance is poor and the price is high. So, in general, except for small bore pipes and special projects (such as pipe jacking works);
Q:How can the cast iron pipe be connected?
Depends on what type of, A type with flange connection, W type stainless steel band clamp connection
Q:The difference between cast iron pipe and ductile iron pipe
I don't understand your question! Both have spigot and socket connection type pipe material, also have flange,
Q:Ductile iron pipe is flexible pipe or rigid pipe
The flexible tube and you say should refer to the common steel pipe and seamless steel pipe, because the two are by the simple method according to the needs and the deformation, in other words, ductile iron is cast out without deformation.
Q:Will the quality of ductile iron shrink?
Fool you. It is normal that the surface shrinks and goes down, but it can not be said to be good.
Q:What is the difference between a PE fire hose and a ductile iron pipe?
Galvanized steel pipe: divided into cold galvanized steel pipe, hot galvanized steel pipe, cold galvanized steel pipe has been banned, and the latter is also advocated by the state for the time being. In 60s and 70s, developed countries began to develop new types of pipes, and galvanized pipes were banned. China's Ministry of construction and other four ministries also issued a civilization, indeed from two, 000 years since the galvanized pipe as a water supply pipe, the New District cold water pipe has rarely used galvanized pipe, and some of the hot water pipe is galvanized pipe. Hot dip galvanized steel pipe is widely used in fire, power and highway.
