Q:It's not easy to drill ductile iron with cobalt high speed steel bit. Please help to point it out
Choose carbide or whole carbide drill, about 90HRC in hardness. But it requires a high number of drills, around 3000.
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 much water seepage is allowed in the water pressure test for water hose DN300?
For water polo hose DN300, hydraulic pressure test allows water penetration to be 17.60 m3 / (24h km).The water pressure test of the indoor water supply pipeline must meet the design requirements. When the design is not specified, the test pressure of all kinds of material supply piping system is 1.5 times of the work pressure, but not less than 0.6MPa.
Q:What is a graphite cast iron pipe?
Ductile iron pipes are pipes made of ductile iron.
Q:Maximum pipe diameter of ductile iron pipe
What I know is that the new ductile iron pipes can reach 2400MM, which can be checked by the official website
Q:The difference between ductile cast iron pipe and machine-made cast iron pipe
Different appearance, ductile iron pipe single length of 6 meters, large wall thickness; mechanism cast iron pipe single length of 3 meters, the wall thickness is thin.
Q:Can ductile iron pipes be installed outdoors?
Ductile iron pipes can be installed outdoors.
Q:Ductile iron pipe, socket connection, pipe length, you can cut open it?
Yes, but the pipe that needs cutting is a cut off pipe with a scissors mark.
Q:Is there any cast iron pipe used in the fire hose?
No, I think so. In theory, you can.See if the specifications have any requirements for the material.
Q:Will the quality of ductile iron shrink?
I am a professional casting, I can certainly tell you what he said, there is no basis, you see, the concave is due to do not have a good time, where the hot metal supplement
