Product Description:

1. Ductile Iron Pipe Description :
It has high strength & hardnes as steel and better corrosin resistance than steerl and grey iron, I ductile iron pipe is the ideal substute for gray cast iron pipe and common steel pipe. In addition, our DI pipes are produced with good straightness, identical wall thickness, high dimension accuracy, smooth surface finished, remarkable mechanical properties and firmly sticking internal & external coating layer as well. Flexible Push-in joint and rubber gasket are used for more convenient installation of pipelines.

Q:How is the weight of nodular cast iron pipe calculated?
In the ferrite and pearlite matrix on the distribution of a certain number of spheroidal graphite, according to the nominal diameter and the elongation of different microstructure of ferrite and pearlite in different proportions of small caliber pearlite percentage is generally not more than 20%, large diameter of the general control in about 25%.
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: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:How can the ductile iron pipe be connected to the PE pipe?
Through the conversion of fittings, because different PE pipes and ductile pipe diameter pipe, so name is needed for the step coupling, called Chinese stepped rod joints
Q:How can the ductile iron pipe be punched?
Main points: manual hydraulic drilling machine and drilling machine, drilling machine is to rely on human features manually through the drill holes in the pipeline: the need for manpower and time, simple operation and economic benefits; characteristics of the hydraulic drilling machine is through the electric pump or gasoline pump driven drill holes: human, mechanical opening. The need for daily maintenance, high cost. General aperture 300mm can be done by hand drilling machine
Q:How to improve the quality of nodular cast iron pipe fittings
When the molten iron temperature is too low and the inner wall temperature of the tube is low, heavy skin defects will occur. When the molten iron temperature is high and the molten iron gas increases, porosity defects can be generated. In the medium frequency furnace, the hot metal should be provided according to the process specification, and the temperature of the inlet and outlet and the cooling rate can be controlled reasonably in the process of production.
Q:Comparison of C and K grades of ductile iron pipes
The nominal pressure ratio of the C class pipe is lower than that of the K grade tube, and the applied pressure is low.
Q:How many kinds of elbow of ductile iron pipe?
You can measure the big money to camber, can call to the manufacturers to build. Seems to have 12.5 and 22.5 degrees, in the first two months we used 22.5 degrees elbow, the drawback is not good pull
Q:Connecting process of ductile iron pipe spigot and socket rubber ring
The material is made of metal rubber. It is a kind of homogeneous elastic porous material. It not only has the elasticity of rubber, but also has excellent characteristics of metal, it can work at -150~800 centigrade temperature. At the same time, it can also bear pressure and within a certain range has dual functions of pressure and seal.
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
