Q:Method for cutting large diameter ductile iron pipe
When the oxygen and acetylene volume ratio is greater than 1.2, is formed. As more oxygen, burning, the flame length is shortened obviously, cone tapered inner flame almost disappeared, and a strong desire. Making due to oxygen, the oxidation of metal, so are not widely used, only used for welding of brass, to prevent evaporation of zinc.
Q:Ductile iron pipe joint damage, water leakage, want to see the connection with other pipe fittings, how to operate?!
The ductile iron pipe can be used as the plugging device for the big part
Q:What is ductile iron pipe?
The main components of ductile iron pipes are carbon, silicon, manganese, sulfur, phosphorus and magnesium. Execution standard GB/T13295-2003ISO2531/2003
Q:Ways of connecting ductile iron pipes
In accordance with the wall thickness or pressure capacity, ductile iron pipe is divided into K8, K9, K10, K11, K12 four class, where the contract does not indicate, according to K9 supply.
Q:Is nodular cast iron pipe filled with Yau Ma Tei?
The main components of ductile iron pipes are carbon, silicon, manganese, sulfur, phosphorus and magnesium. Perform standard [span]GB/T13295-2003 ISO2531/2003
Q:Can ductile iron be welded? Is weldability comparable to gray iron?
Nodular cast iron welding can be determined, this should be in some high strength cast iron equipment used more, the tensile strength of normally ductile cast iron welding in welding is higher, is worse than the grey cast iron, it is actually very difficult to distinguish with the naked eye is ductile iron or cast iron the iron in the repair equipment, we usually use WE777 special cast iron electrode universal wide welding, but it is only for maintenance use, the effect is really good, reducing the risk of cracking and high strength welding rod matching to ensure the strength of welding.
Q:When the ductile iron pipe is pressed, the three links are always running out. What should be done?
If the conventional backfill soil pressure, pipe fittings installed properly, the phenomenon will not appear.
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:Method for cutting cast iron pipe
Generally cast iron pipe wall thickness, crisp texture, with traditional saw blade, saw blade cutting, very expensive cutting materials, and cutting accuracy is not high. Nowadays, the cutting tools and cutting machines on the market cut off these kinds of pipes, which are fast and cutting tools. Because the length of the pipe is not cut, the pipe can be continuously cut for a while after the equipment is loaded on the equipment. The worker can spare more time and can realize the operation of more than one machine, thus greatly improving the cutting efficiency. Rotary tool pipe cutting machine cutting cast iron pipe sawdust granular, easy chip removal, cutting section of vertical high, smooth surface without burr. The current equipment has been widely used in cast iron pipe cutting, especially iron pipe cutting, even cylinder car production.
Q:What is the K9 standard pressure for ductile iron pipes?
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.
