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?
Ball milled cast iron pipes can be opened and the opening size depends on the main pipe. For example, the main pipeline is DN100, diameter 118 milling pipe, can open the 100mm maximum aperture (with aperture opening), commonly used manual opening now the minimum 20mm, maximum 600mm, maximum 800mm hydraulic hole, open hole drilling machine dedicated
Q:How can ductile iron pipes be connected to steel tubes?
Disk or disk plug connection, it is best to use flange connection.
Q:How can the ductile iron pipe be connected to the PE pipe?
Cast iron pipe and PE pipe is connected with a lot of what is the most secure connection, flange connection (PE flange head + anticorrosive steel flanges + rubber gasket).
Q:How much is the installation of a two degree elbow for ductile iron pipe fittings at 11.25 degrees?
The following is the ductile iron pipe specification and quotation: name of material specifications (KG weight / root unit note DN100 ductile cast iron ductile iron DN150 9552006 meters 14441006 meters 19440006 meters DN250 DN200 ductile cast iron ductile cast iron ductile iron DN300 25506 meters 32339506 meters 40306 meters DN400 DN350 ductile cast iron ductile iron ball 48239506 meters DN450 graphite cast iron ductile iron DN500 57740506 meters 66940506 meters 88241506 meters DN700 DN600 ductile cast iron ductile cast iron ductile iron DN800 112342506 meters 139443006 meters 169006 meters DN1000 DN900 ductile cast iron ductile cast iron ductile iron DN1200 201706 meters to 275806 meters
Q:Is the cast iron tube the same as the ductile iron pipe?
According to its manufacturing methods can be divided into: sand, centrifugal pipe, straight pipe, continuous cast iron pipe and sand pipe.According to the material used, it can be divided into gray iron pipe, nodular cast iron pipe and high silicon iron pipe.
Q:Is the ductile iron pipe metal pipe?
Ductile iron pipes are metal tubes, because ductile iron is also a kind of metal. See the classification of metalsGenerally, metal materials are classified into two major categories: ferrous and non-ferrous metals
Q:Could you tell me how to weld ductile iron parts and steel tubes?
Welding cast iron is mainly in three aspects: carbon control, stress elimination, structural adjustment. You can choose better welding materials, such as WE777 and other imported welding materials. Crack resistance is very good. In addition, the sewing process can be adopted in the structure to increase the stability of the welding effect. You can learn more about WE777 welding applications.
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 to inspect ductile iron pipe fittings?
While the proportion of the so-called K8 class cement pipe and some manufacturers terrifying 3/4 or 3/5, as the water supply pipe 3/5 or no personally think that two of the proportion of the tube is not the problem, the most intuitive way of judging the quality of ductile pipe is cement and iron thickness ratio of thicker tube wall thickness of cement the better the quality, some manufacturers of production pipe, thick wall pipe head cast iron part looks to be thick, but there is also a thin iron pipe, so the judge quality to cut inside, personally think that the highest price of the manufacturer is Jinan steel, Jinan Iron and steel because the pipe quality can reach the national standard K9, the price is also below new, Saint Gobain and other major brands, as the water supply pipe K8 is no problem, but the price and quality for the construction of what importance Stronger.
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.
