5.FAQ:
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:How many kinds of elbow of ductile iron pipe?
There are 12.5 degrees and 22.5 degrees elbow, but manufacturers rarely produce. You can consult the manufacturer on the Internet
Q:Comparison of C and K grades of ductile iron pipes
C grade tube is the latest international standard for ductile iron pipes. The product standard is ISO2531:2009, which is compared with the original standard ISO2531:2003 class K pipe code. Pipe usage remains unchanged. But the new standard (C pipe) classification is based on the allowable work pressure grade of the pipe, while the original standard (grade K tube) is classified according to the pipe wall thickness grade.
Q:Is the ductile iron pipe metal pipe?
Ferrous, manganese, chromium, or a substance with a metallic property based on them is called ferrous metal. Ferrous metals are carbon steel, alloy steel, cast iron, etc.
Q:How can the ductile iron pipe be punched?
Ductile iron should be drilled, the key is to see how big holes. If it is a small hole, you can consider using a small drill around 5mm to slowly wear the pipe, and then gradually reaming. If the fight is relatively large hole, may according to the aperture required first hit a circle hole, and then use a small chisel chisel down, slowly put the plate again to be trimmed. When drilling, add a little oil to cool the drill bit.
Q:How to inspect ductile iron pipe fittings?
On the quality of single pipe can analyze it from the surface is sand type and water cooled pipes, K8 pipe is different from Shanxi root nature is that the proportion of grade K9 cement and cast iron pipe and the K8 pipe are different, there is no national standard and non standard, no K8 tube, only is the production plant in order to obtain more profits, the dealer is not up to the national standard K9 grade pipe called K8 grade ductile pipe, K9 pipe cement weighs about 1/5 weight of the pipe, but is played in the role of anti-corrosion,
Q:Connecting process of ductile iron pipe spigot and socket rubber ring
Rubber seal ring is formed by one or several parts of the cover, fixed in a ring or a washer bearing and another ring or gasket contact or the formation of the labyrinth of narrow gap, to prevent leakage of lubricating oil and foreign matter.
Q:Is the cast iron tube the same as the ductile 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. Divided into gray cast iron pipe and nodular cast iron pipe according to different material. According to the interface form, it is divided into flexible interface, flange interface, self anchored interface, rigid interface and so on. Among them, the flexible iron pipes rubber sealing ring; flange interface cast iron pipe flange fixed in the rubber pad, the flange gasket sealing; rigid interface cast iron pipe socket is large, straight pipe is inserted, sealed with cement, this technology has been basically eliminated
Q:What are the categories of ductile iron pipe fittings?
The heat pipe trench is in rotational groove tube internal high temperature composite cold water general PE, cohesive force is very strong and do the destructive test will be found with a knife, the pipe made by hot plastic process, lined with PE layer inside the hard to cut down. The injection pipe is a kind of composite pipe formed by injection of PP into the inner part of the groove pipe.
Q:How can the ductile iron pipe be connected to the PE pipe?
Other ways of connecting steel and plastic excessive, one end is PE, and the other end is iron pipe fittings, but not as reliable as flange pressure, different systems pipe connection, it is recommended to use flange connection.
Q:How to improve the quality of nodular cast iron pipe fittings
To avoid the iron pipe inner wall of mold management lean reduce iron pipe pipe mould run speed, can make a dense and uniform pitting; avoid mold wall cast iron pipe pipe packed too shallow, increase the pressure, wear a good play to nod, can ensure the suitable depth of pitting.For pipes with grease and debris on the inner surface, especially the new cast iron pipe fittings, the grease and sundries on the surface of the cast iron pipe can be removed before use. For the cast iron pipe mould with a crack of a turtle, it is slight to use. When in use, the amount of mould powder should be increased; if the crack of the turtle is serious, the cast iron pipe mould must be replaced in time.
