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:How can the ductile iron pipe be tested?
Pipe in water pressure test, step by step step by step step up, and each time the boost value is 0.2 MPa, in each time after the boost, the heart must be determined after the voltage regulator can continue to step up
Q:The role of chromium in nodular cast iron
Chromium has better strengthening and toughening effect in nodular cast iron. Chromium containing cast iron has the characteristics of high strength, high elongation, high impact value and low hardness.
Q:Some questions about the bearing capacity of nodular cast iron pipes!
The pipe diameter is D, the tube thickness is T, and the internal bearing pressure P is related to the yield limit [S] of the pipe:PD=2T[S]Or [S]=PD/ (2T)If the P=3MPa, D=300mm and T=6 mm are substituted, the pipe yield limit should be given[S]=3*300/ (2*6) = 75 MPaI think the ductile iron pipe's yield limit should be greater than this value. Factory production should be all right. Only ductile iron pipe production, low product specifications, prices are higher.
Q:What is the use of ductile iron?
Ductile iron is used as a conduit at the beginning. Iron pipes and fittings are mostly produced by major industrial countries. Their manufacture, design and use are in line with national standards and international standards and procedures (I502531). As far as water and other liquids are concerned, it has long been proved that ductile iron pipes are superior to gray iron pipes. The main reason for this change is the combination of strength and toughness of Ferritic Ductile Iron, which makes the pipes made of this material subject to high operating pressures and can be readily loaded and laid during laying. A gas pipeline must be able to withstand multiple use requirements, which stand near the pipeline excavation and municipal engineering construction and transportation, where the ball iron pipes with high strength, high performance and simple installation and connection technology has proved that this material selection is decisive.
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:Water supply pipe is ductile iron, then it's fittings and valves and other parts must be ductile iron?
Not always。Valve material selection is mainly determined by the fluid medium.The medium can be divided into gas, liquid, corrosive gas, liquid and oil. According to different media, temperature, and pressure levels, choose different materials, plastic, cast iron, cast steel, stainless steel and so on.
Q:How do we handle the leaking of the ductile iron pipe?
If it is installed in the pipeline, test pressure leakage, glue can be repaired and then welded, usually with hoop.
Q:Which direction should the spigot of the K9 ductile iron pipe be installed?
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:What is the relationship between the installation direction of the ductile iron pipe and the direction of flow?
Suppose the water flows from east to west, then the pipe mouth is in the East socket at the West
