We have organized several common questions for our clients,may help you sincerely:
1.Q: Why would you choose ductile iron pipe fittings rather than other pipe fittings materials?
 A:The reasons are obvious for that not only ductile iron pipe fittings 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 fittings, improving resistance to erosion of the sewage components.

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 can ductile iron pipes be connected to steel tubes?
First insert a flange plate on the ductile iron pipe and then screw it with the flange on the weld 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 many kinds of elbow of ductile iron pipe?
Speaking from the elbow interface double disc, three double socket, socketEach interface elbow from speaking with 90 camber 45 22.5 11.25 four anglesSo a total of 3*4 =12 elbow
Q:How much is the installation of a two degree elbow for ductile iron pipe fittings at 11.25 degrees?
Ductile iron pipe, executive standard, GB/T13295-2008ISO2531/2008, national GB/T13295-91 standard, ISO2531-K9 class.
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: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:Could you tell me how to weld ductile iron parts and steel tubes?
Disk or disk plug connection, it is best to use flange connection. First insert a flange plate on the ductile iron pipe and then screw it with the flange on the weld pipe. But note, because ductile iron pipe material is crisp, and the two connecting flange sealing surface is best all the plane, in order to prevent damage due to uneven iron flange.Material is different, ductile iron pipe is made of ductile iron, seamless steel pipe is made of structural steel. Such as No. 20 steel, No. 35 steel, 16Mn steel and so on. The two is the manufacturing process is also different, ductile iron pipe is generally sand casting molding; seamless steel pipe is made of billet through seamless steel tube mill hot rolling molding.
Q:How is the weight of nodular cast iron pipe calculated?
The use of cast iron by adding more than 18 nodularizer, after centrifugal ductile cast iron machine high speed centrifugal cast pipe, called "ductile" (Ductile Cast Iron Pipes), referred to as ball pipe, ductile iron pipe and ductile iron pipe etc.. The utility model is mainly used for conveying water, and is an ideal choice for tap water pipes.
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,
