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:Luo what effect of ductile cast iron
Chromium can improve the hardness, strength and wear resistance of nodular iron, and increase bainite in bainite ductile iron.
Q:How much is the working pressure of ductile iron pipe used in water supply pipe and how is MPa determined?
In general, building materials products are production standards, the production process and specifications are required, pipe work pressure is based on the use of coffins and other factors set standards, pipes with different purposes, the pressure level is different.
Q:How much pressure can the ductile iron pipe socket meet?
After all, he is not steel, strength is low, toughness is poor. But a short period of about 100kg, things should be no problem.
Q:Ductile iron pipe joint leakage
After cleaning the pipe mouth, the cf-2000 high efficiency composite waterproof agent is used to seal it, and it will not leak.
Q:What are the advantages and disadvantages of spheroidal graphite cast iron?
As a substitute for steel, man developed ductile iron in 1949. The carbon content of cast steel is less than 0.3%, while that of cast iron and ductile iron is at least 3%. The low carbon content in cast steels makes the carbon free of graphite free of structural flakes. The natural form of carbon in cast iron is the form of free graphite flakes. In ductile iron, the graphite flakes change into tiny spheres by special treatment. The improved sphere makes ductile iron more superior in physical properties than cast iron or steel. It is the globular microstructure of this kind of carbon that makes ductile iron more ductile and impact resistant, while the thin form of cast iron causes the cast iron to be free of ductility. The best ductility can be obtained by ferrite matrix.
Q:Ductile iron pipe connection mode
Jack painted on the outer surface and rubber lubricant: lubricant evenly installed ring inner surface, outer surface coating in the socket to socket socket parts lubricant line all the brush in the socket.
Q:What is the exterior anticorrosion of nodular cast iron pipes?
Spraying anti-corrosion paint, usually first spray a anticorrosive paint, and then primer 2, paint 2!
Q:How does the white iron appear in the case of ductile iron?
Casting cooling, surface and thin section at often produce white. White tissue hard and brittle, poor processing performance, easy peeling. So it is necessary to use the annealing (or normalizing) method to eliminate white tissue. The annealing process: heating to 2 DEG C 550950 ~ 5 h, then 500 to 550 DEG C Furnace cooling again followed by air cooling. During high temperature insulation, high travel cementite eutectic cementite decomposition of graphite and A in the subsequent two carburizing cooling process and eutectoid cementite decomposition, graphitization process. Due to the decomposition of cementite, resulting in the decrease in hardness, thereby improving machinability.Hope to help you.
Q:What is the difference between a cast iron pipe and a ductile iron pipe?
Nodular cast iron has high strength and strong plasticity. The tensile strength of ductile iron is twice that of gray iron, and the yield strength even exceeds that of cast steel.
