Q:Why does the cast iron pipe always run off when testing?
If the pipe is exposed for pressure test, you must add a pier, or else the fittings fly out. You are not surprised. At the same time, the pressure test before the ink tube to make full immersion bubble discharge clean, or a big easy gas pressure pipe explosion.
Q:Is it better to use steel tubes or ductile iron pipes for water supply?
Flexible seamless steel pipe is good toughness, good processing, better than ductile iron corrosion resistance, the price is slightly higher;
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:What does ductile iron pipe "K" mean?
The higher the K level, the better the quality, and the national standard requires K9
Q:How to analyze and judge the quality of ductile iron pipe
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, the so-called K8 class water mud proportion 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 no problem
Q:Is the fire hose capable of using rapid repair joints?
Clear。 Before installation, cleaning work should be carried out, the parts to be cleaned include: socket end, the mouth of the socket, the corner of the socket to the white line should be smooth, no sharp points, so as not to wear aprons when installation.
Q:What if the ductile iron pipe is broken?
Ductile iron pipe rupture can be repaired by using a cast iron defect repair machine, that is, a cast iron defect repair device. However, the general use of iron defects repair equipment can be repaired welding, and will not affect its use. Ductile iron pipes are used for water supply, so if it breaks, it will not be easy to handle. Make sure that the main valve is closed and repaired.
Q:Do rigid cement cast iron pipes need cement piers?
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 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:The difference between cast iron pipe and ductile iron pipe
I don't understand your question! Both have spigot and socket connection type pipe material, also have flange,
