Q:What is the manufacturing process of ductile iron pipes? Thank you
Ductile iron pipe is a pipe dream of urban water supply, gas pipelines, sets of high strength, good ductility and corrosion resistance strong strength, has the essence of iron, steel, cast iron pipe and steel pipe is a traditional popular replacement products, is a kind of widely used pressure water supply, gas and send pipes. Has the advantages of high strength, good toughness, corrosion resistance and easy device and other excellent characteristics, is the traditional grey iron and steel pipe replacement products popular, has become the preferred data of water supply, gas industry, set high strength, good ductility and corrosion resistance strong strength, has the essence of iron, steel, is the traditional cast iron pipe and steel pipe replacement products under the popular small as you introduce the ductile iron pipe is how to make the.
Q:How much is the working pressure of ductile iron pipe used in water supply pipe and how is MPa determined?
No, the work pressure is generally 0.4~1.6MPa, but the ultimate test pressure of ductile iron pipes is about 4.0MPa.
Q:What does "K8" mean in ductile iron pipe grades?
K9 is GB, K10 is specially customized, K8... Strictly speaking, it is not up to standard, standard length, wall thickness and so on.. Many workshops, grades of factory products, such as K9, standard length 6.15M, K8 is 6M, wall thickness from the beginning of DN100, are thin on the point.
Q:What does ductile iron pipe "K" mean?
The higher the K level, the better the quality, and the national standard requires K9
Q:How many casting methods are there in ductile iron casting? A 60*6 discus can not have sand holes. Its surface is smooth. What process can be used to make it?
The metal mould is ok! The surface quality of the casting is better than that of the sand mold. But later heat treatment is needed.
Q:What if the ductile iron pipe is broken?
Ductile iron pipes can be broken with a large piece of repair sectionIn the medium and low pressure pipe network, nodular cast iron pipe has the advantages of safe operation, low breakage rate, convenient construction and maintenance, excellent corrosion resistance, etc..
Q:How to properly maintain FRP pipes
It has excellent corrosion resistanceDo not use cathodic protection and other anti-corrosion measures to produce two contamination of water and other media. Long service life of products.
Q:Ductile cast iron can replace copper sleeve
The tensile and compressive capacity of the ball milled cast iron is not as good as that of copper. The hardness of Rongchang graphite copper sheath can reach HB210
Q:What is the excavation width of ductile iron pipes with diameters greater than 1400?
When the condition does not allow enough slope, it is necessary to do wall protection and other means to ensure safetyRemind me, such a big pipe, dig deep in two ways. One is the depth diameter (range at the junction of 1.6 m in length and 500 for manholes and operation. The lower bolt assembly when) there is a depth diameter plus 500. and then in the trench laying branch the pier, installed after the fine stone tamped backfill.Can also be buried directly with the pipe diameter, and then put into the assembly. This method requires a large space on the ground, otherwise, the volume is too large after assembly, weight is too heavy, may cause damage to the pipeline and personnel injuries
Q:Ductile iron pipe converter, steel transition DN100 turn 100, what is the specific accessories name? Can you supply photos?
Strong toughness: the pipe can be stretched to 5 times the original length without fracture, which is suitable for uneven geological conditions without affecting its link performance. In the case of a breach, there is no extension of the mouth due to the breach.
