5.FAQ:
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:What are the categories of ductile iron pipe fittings?
But even if it is plastic and rotational, between the two in the process and the use of the effect also has the essential difference. Pipe fittings, usually coated with epoxy resin in ductile iron grooved pipe fittings. But this kind of pipe in the process without heat pipe trench because of rotational rotational adhesion as mature, its internal plastic heat pipe trench.
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?
There are 12.5 degrees and 22.5 degrees elbow, but manufacturers rarely produce. You can consult the manufacturer on the Internet
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?
MG289 electrode can be selected, welding electrodes and ductile iron into eighty degrees around the pipe around OK, and the intensity is higher than the strength of the cast iron. Direct cold, no heat treatment after welding.
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.
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: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.
