Q:A tube is used only in ductile iron pipes, isn't it?
Ductile weakness: ductile cast iron pipes connected by human factors such as the operation level of responsibility, influence, construction not convenient. The advantages of PE PE PE pipe has good corrosion resistance and its anti inorganic performance than that of the metal pipe is much stronger in the buried without corrosion, construction convenient. Small diameter PE pipe in the price performance ratio is better than that of steel and ductile iron.PE tube have disadvantages: benzene, gasoline, carbon tetrachloride and other organic solvents have certain effect on pe. If the organic solvent is infiltrated into the polyethylene, the swelling will occur, and its physical properties will be decreased. Its pressure resistance and temperature resistance are poor.
Q:How long does the cast iron pipe of indoor direct buried sewage need to be examined?
Indoor drainage of the majority of households are using cast iron pipe, if the distance from the sewage well is relatively close, and the above does not take the car, you can consider the U-PVC.
Q:How can the old water pipe ductile iron pipe be opened with three flanges?
There are finished products with flanges, but they are not easy to buy. They are basically useless. Now basically the adoption of the pipe, so it is recommended to use the tray flange, disk plug: one for the flange, one for the socket; socket: one for the mouth, one for the socket. According to the diameter of pipe fittings, there are usually equal diameter three pass, different diameter three pass and so on. According to the direction of branch pipe, there are three straight and oblique three. In accordance with the connection mode, there are three ordinary, threaded three pass, card sleeve three, and socket three. The connecting flange of the sleeve is connected with the connecting angle of the bearing mouth, and the telescopic device can also be used. The connection between the pipe and the pipe adopts the form of socket type or flange disk interface. According to the function, it can be divided into two kinds: flexible interface and rigid interface. The flexible interface is sealed with rubber ring, which allows a certain degree of corner and displacement, so it has good seismic resistance and tightness, and it is easy and quick to install than rigid interface.
Q:What are the differences between ductile cast iron pipes and centrifugal ductile iron pipes?
Small, thin pipe fittings are usually rolled or continuously cast, and large, thick pipes are usually centrifugally cast. Compared to sand casting, the tissue is compact and homogeneous.
Q:Advantages and disadvantages of ductile iron pipes?
Ductile iron pipes are commonly made of flexible sealing rings and slip through connections. The main mechanisms are W and B, clamps and mechanical connections, and inner gaskets.
Q:Advantages and disadvantages of ductile iron pipes
The ductile iron pipe is widely used not only in foreign countries, and has also been in the country to promote the use of good, in many areas of our country, ductile iron pipe has been widely used in medium and small diameter water supply pipe; compare the performance of ductile iron pipe and steel pipe: steel pipe can be divided into seamed steel pipe and seamless in the water supply pipe, commonly used in welded tube. Compared with ductile iron pipes, the steel tube has the advantages of good toughness, high tensile strength, thin tube wall, high pressure resistance, long pipes and less interfaces. The biggest drawback is that the corrosion resistance is poor and the price is high. So, in general, except for small bore pipes and special projects (such as pipe jacking works);
Q:DN1800 can the length of ductile iron pipes be several meters? What is the total weight?
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.
Q:How can stainless steel pipes and ductile iron pipes be joined?
The stainless steel pipe can be used as a socket or socket, so as to be directly connected with the connection mode of the ductile iron pipe
Q:How long is the service life of the cast iron pipe, and the time of use of ductile iron pipes?
Ductile iron is a new type of pipe, as long as we use it properly, the quality of its products, then the use of ductile iron pipes for 20-35 years, basically no problem. But whether it is ductile cast iron pipe, or some other things, the use of more years, and more or less, there will be some problems, ductile iron pipe can not escape the robbery. However, as long as we use the ductile iron pipe in the process of careful care, the service life of the problem is not to worry about.
Q:What kind of valves are commonly used in ductile iron pipes?
Gate valve, butterfly valve, globe valve, check valve flange of various valves, (but the pipeline used for water supply and some limitations of the transport medium may be prescribed valve type) now due to material improvements in the technology, in most cases, smaller pipe diameter is also large diameter pipe outlet valve, butterfly valve, because of the pipeline the large diameter pressure in the pipeline and water than the small caliber to open and close the valve, to human hard, efficiency is not high, so for butterfly valve,
