Q:How can the steel plastic composite pipe be connected with the cast iron pipe?
Use stainless steel clamps to connect.
Q:What is the acceptance of cast iron pipe material?
Specific acceptance, first of all in line with national standards, followed by the provisions of the contract, and then the project requirements. General contract and drawings will have the requirements and standards of pipe. I hope I can help you.
Q:Classification of cast iron pipes
Drainage cast iron pipe:Pipes and fittings for plain cast iron bearing. Flexible anti-seismic interface cast iron pipe, this kind of cast iron pipe is sealed by rubber ring and bolt fastened. It has good flexibility and flexibility under water pressure. The utility model can adapt to larger axial displacement and lateral deflection, and is suitable for indoor drainage pipes of high-rise buildings, and is particularly suitable for earthquake zones. From the interface form, can be divided into: W flexible cast iron drain pipe, B flexible cast iron drain pipe, A flexible cast iron drain pipe.
Q:What's the difference between ductile iron pipe and cast iron pipe?
We have to correct now basically all socket ductile iron pipes, because the socket type with a rubber ring, plus a ductile material, buried beneath it when the bearing has a certain flexibility, not because of the deformation and leakage phenomenon. To be used, not Unicom cast iron pipe socket, connection is used similar to the stainless steel hoop hoop sleeve closed.
Q:Disadvantages of ductile iron pipes
The strength of nodular cast iron is comparable to that of cast steel. Ductile iron has higher yield strength, the lowest yield strength is 40K, while the yield strength of cast steel is only 36k.
Q:How much is the installation fee of the 400 largest ductile iron pipe?
Compared with the PE pipe, from the installation time, ductile pipe PE pipe installation is simple and rapid, and after the installation of internal and external pressure bearing better tightness and corrosion resistance; from the point of view, ductile pipe sealing better after installation, but also can improve the corrosion resistance through various anti-corrosion methods;
Q:The design uses water supply ductile iron pipe, PE corrosion protection pipe, HDPE pipe, please ask that good? What's the price of the two?
Ductile iron pipes are difficult to make and do not make money, and even easy to lose money, it is not recommended to do, the price can be found on Baidu. DN100 6, about 400 yuan ~500 yuan, DN200,6 about 900 yuan ~1000 yuan, when the market to buy to ask a length. Difficult to do in ductile pipe easily affected by topography (when digging the trenching dug in front of the back of their repair, trouble), vulnerable to local soil effects (such as settlement). Parts connection is not fixed, easy to leak. The advantage is that once the installation is completed, the pressure test is successful and is used for life.
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 is the relationship between the installation direction of the ductile iron pipe and the direction of flow?
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:Ductile iron pipe length is generally much
6 meters, the bassoon is also 8 meters!
