Q:What does ductile iron pipe "K" mean?
1 、 pipe fittings are K type, T type, etc.;2 wall thickness registration symbol. For example, according to the pipe quality standards GB/T13295-K9, which is the wall thickness ofK=9* (DN/1000+0.5)
Q:The difference between ductile cast iron pipe and machine-made cast iron pipe
Of different uses, ductile iron pipes are widely used for municipal water supply and drainage, rural drinking water and outdoor fire fighting works; mechanism cast iron pipes are mainly used in the city.
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:Is the spigot and socket connection of the ductile iron tube reversed?
The whole process is formed by the radial compression of the pipe blank and the stretching process of the branch pipe. Different from the hydraulic bulging three, the metal of the three way joint pipe is compensated by the radial movement of the tube blank, so it is also called radial compensation process.
Q:QT400-10 nodular cast iron requires hardness of HRC47~51. Why can't quench hardness be reached?
Because of the high tempering stability of the nodular iron, the tempering temperature is 400-450 degrees, and the tempering time is 1 hours.
Q:Does the cast iron pipe for spheroidal graphite need corrosion protection when laying underground?
Ductile iron pipe is a kind of cast iron pipe.
Q:Ductile iron pipe, socket connection, pipe length, you can cut open it?
The cutting length is 4 meters from the jack. Among them, DN300 below 100% can be cut, DN350 above shear ratio is 10%, cut the small head to do chamfering treatment.
Q:Fire water supply network adopts ductile iron pipe, the test pressure should be no more than MPa
To your selected fire pump highest lift 1.5 times to suppress, generally not more than 1.6MPa, if the use of ductile iron pipe, test pressure according to 2MPa to suppress.
Q:The difference between spheroidal graphite cast iron pipe and HDPE water supply pipe
(4) HDPE pipes do not need corrosion protection. If the water supply pipeline is made of ductile iron pipe, the inner and outer walls of the ductile iron pipe shall be treated with corrosion protection.(5) the normal service life of the ductile iron pipe is 20~25 years after the pipe is treated by inner and outer walls. The HDPE tube has no corrosion, and the normal service life is 50 years.
Q:Ductile iron pipe length is generally much
The water-cooled metal ductile iron pipe has a single length of 6 meters, and the current mainstream ductile tubes are water-cooled metal ductile iron pipes.
