  • Facilitating high resistance to loadings, pressure and vacuum with high tensile strength,

  • Enabling high resistance to corrosion,

  • Not requiring cathodic protection,

  • Less operating cost since cast pipes have larger nominal diameter than polyethylene pipes.

  • Being the best pipe in case of an earthquake, with its ability of resilience and resistance to impacts without deformation,

  • Long product life, exceeding 50 years,

  • Preserving the quality of water with healthy interior coating.

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?
But pay attention, because ductile iron pipe material is crisp, and the two connecting flange sealing surface is best all the plane, in order to prevent the uneven force and damage to cast iron flange.
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:Is the cast iron tube the same as the ductile iron pipe?
You are mistaken in concept. The cast iron pipe is the sort of connection method. The ductile iron pipe is classified according to the material.
Q:Is the ductile iron pipe metal pipe?
Ductile iron is an alloy of ironDuctile iron pipes are alloy tubes of iron
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
For cast iron pipe chute taphole bent or improper chute taphole distance socket distance, easy to form a skin defect in cast iron pipe socket parts, equipment manufacturing inspection of cast iron pipe fittings must be in production, replacing the cast iron pipe chute taphole elbow when necessary, and adjust the host making iron centrifuge when the pipe in the lower limit, shorten the chute taphole socket from the distance.
Q:How is the weight of nodular cast iron pipe calculated?
Ductile iron pipe is a kind of cast iron pipe. In quality, the spheroidization of cast iron pipes is controlled to be 1-3 (spheroidization rate 80%), so the mechanical properties of the cast iron pipes, ductile iron pipes and finished product libraries can be better improved, with the nature of iron and the properties of steel. Ductile cast iron pipe after annealing, the microstructure is ferrite and pearlite, good mechanical properties, excellent corrosion resistance, good ductility, good sealing effect, simple installation, mainly for municipal, industrial and mining enterprises, water supply, gas, oil etc..
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.
