Q:How much is a ductile iron pipe dn400?
Ductile iron pipe nominal diameter is 80 ~ 2200 mm, compared with grey cast iron, high strength, good toughness, thin wall metal, less dosage, and can withstand high pressure, effective length of 5 meters, 6 meters and 8 meters; according to the different thickness of P, G two. It is the development direction of cast iron pipe.
Q:What is the relationship between continuous cast iron pipe and ductile iron pipe?
In general, the continuous cast iron pipe is the continuous casting of gray cast iron pipe, while the centrifugal cast iron pipe is centrifugal ductile iron pipe. Of course, you have to be hard, just to make continuous ductile iron pipes, that's what you want.
Q:The difference between HDPE pipe and ductile iron pipe
Production process is different, ductile iron pipe mainly through intermediate frequency furnace heating, annealing, and then do cement lining cement lining production, the mechanism of cast iron pipe does not make cement lining.
Q:How much is the working pressure of ductile iron pipe used in water supply pipe and how is MPa determined?
Upstairs are positive solutions, but now outdoor buried water pipes are using steel wire mesh skeleton, plastic composite pipe instead of ductile iron pipeThe general pressure grades used for water supply pipes are 1.0MPa and 1.6Mpa
Q:What does "K8" mean in ductile iron pipe grades?
1 ductile iron pipe grade K8, on behalf of the ductile iron 8 grades, K refers to the wall thickness coefficient, the higher the grade, the greater the pressure, the lower the level, the less pressure to bear.2 wall thickness calculation formula: e=K (0.5+0.001DN).
Q:What is the relationship between the mechanical properties of spheroidal graphite cast iron and its spheroidization rate?
The spheroidization level reflects only the final shape of graphite. The higher the spheroidization level of ductile iron is, the better its performance is, but this is not entirely the level of spheroidization to determine.The mechanical properties of nodular cast iron are closely related to its microstructure. Different grades of ductile iron require different mechanical properties such as tensile, yield, elongation, impact and hardness.
Q:Is the spigot and socket connection of the ductile iron tube reversed?
The three pass joint is formed by flattening a tube blank larger than three through diameter to approximately three through the diameter and opening a hole at the point of the branch pipe;
Q:Can ductile iron pipes be made into clear tubes?
Of course, you can also use as a pipe, but because of the appearance of cast iron pipe is not very beautiful, but relatively brittle, by external impact or bad insulation cold winter break, so according to your use of the environment to determine.
Q:Nodular cast iron, heat treatment process and so on
White cast iron is one of the defects. Firstly, control of carbon equivalent, carbon equivalent is not too high. The second inoculation is reasonable, the step of determining whether carbon in cast iron with graphite precipitation. Ensure adding good inoculant humectant and sufficient time. Once again, the problem of cooling. The cooling can not be too fast, easy fast cooling to produce white tissue.
Q:What is the use of ductile iron?
As far as the tonnage is concerned, the automotive industry is the second largest producer of ductile iron castings, with the largest number of them. Ductile iron is used in three main parts of automobiles: (1) power source, engine parts; (2) power transmission of a gear train, gears and bushings; (3) vehicle suspension, brakes and steering gear. The power source is subjected to continuous change of the crankshaft bending, torsion and shear load, and in its service life, to one billion cycles of car design engineers early in the 19152 years that the processing method for magnesium found in four years later, immediately consider the possibility of using ductile iron. Almost all crankshafts of Ford motor are made of this material. Most gasoline engines in the world are fitted with ductile iron crankshafts instead of forged steel crankshafts, which are considered a typical example of value engineering.
