Q:How much water seepage is allowed in the water pressure test for water hose DN300?
Test method: metal composite pipe and water pipe system 10min observed in the test pressure, the pressure drop should be no more than 0.02MPa, and then reduced to working pressure check should be no leakage of plastic pipe; water supply system should be in the test pressure regulator 1H, pressure drop shall not exceed 0.05MPa, then stabilized at 1.15 times the working pressure of the state under 2h, the pressure drop shall not exceed 0.03MPa, and check each connection must not leak.
Q:How can the cast iron pipe of the ductile iron pipe be repaired?
If it is ductile cast iron pipe, then use the plugging device can be used in the mouth of the big head plugging device, then use ordinary plugging device, if it is bent, we need on-site survey to do plugging device
Q:Why does the construction wastewater system use ductile iron pipes instead of galvanized steel tubes?
Then answer your question: first, the strength of ductile iron is much higher than that of ordinary low carbon steel, such as Q235. Corrosion resistance is much higher than that of ordinary steel pipe and the cost is lower than that of ordinary steel pipe. Second, large diameter steel pipe can only be made of spiral welded pipe, seamless steel pipe is particularly expensive, will not be used. The welded pipe is welded, easy to corrosion water leakage. Third, galvanizing is also a life and very expensive, the pipe has a fluid will wear on the inner wall, zinc plating is meaningless. Galvanized pipe is generally used as a water supply pipe, large caliber water pipes, such as more than 250, and now do not use steel pipes, mostly plastic pipes
Q:Is the crankshaft material forged or ductile iron?
Other crankshafts are not clear about the car crankshaft. These two materials are useful, but the trend is to use ductile iron
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:General cast iron prices now
Hubei, Suizhou, in 2010, normally 5000-7000 tons of iron, if required to join copper and other metals, the price is calculated. The price is very low, because the market price in Suizhou is the lowest in the whole country. Under normal circumstances, it should be 8000 tons a ton
Q:Which direction should the spigot of the K9 ductile iron pipe be installed?
Ductile iron pipes mainly called centrifugal ductile iron pipe, it has the properties of nature, iron and steel, excellent corrosion resistance, good ductility, good sealing effect, simple installation, mainly for municipal, industrial and mining enterprises, water supply, gas, oil etc.. Water supply pipe is the first choice, with high cost performance.
Q:What's the function of the cement mortar lining of ductile iron pipes?
In brief, the cement mortar lining system has the following advantages:1. provide active protection better than barrier coating2. meet both national and international standards for contact with potable water3. can be used in the strict requirements of the occasion4. strong and shock resistant5. suitable for a wide range of applications6. easy to repair7. over 100 years of service life
Q:Ductile iron pipe length is generally much
The spheroidal graphite tube of hot film casting process is generally a single branch with a length of 8 meters. The ductile iron pipes produced by this process are usually large caliber pipes. For example, DN1000 or more.
Q:Method for joining cast iron pipes
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. It is easy and quick to install than rigid interface. It has little labor intensity according to the casting method.
