Q:Is there any cast iron pipe used in the fire hose?
I don't know, I only know that the fire pipes produced by our company is the base tube is a pipe, and then coated with a corrosion and non-toxic, long service life, we are Suzhou Yuyao Pipe Industry Co. Ltd. is a professional production of the manufacturers, oh
Q:Can the sealing ring of ductile iron pipe be reused?
The sealing ring is hard to install and take off. I have been in this line for six years. I haven't seen it removed. The rubber ring itself is not expensive. It is not necessary to reuse it.
Q:What is ductile iron pipe?
Ductile iron pipe is a kind of cast iron pipe. In quality, the spheroidization of cast iron pipes is controlled to be 1-3 (spheroidization rate 80%), so the mechanical properties of the material have been better improved, with the nature of iron and the properties of steel. Ductile cast iron pipe after annealing, the microstructure is ferrite and pearlite, good mechanical properties, excellent corrosion resistance, good ductility, good sealing effect, simple installation, mainly for municipal, industrial and mining enterprises, water supply, gas, oil etc..
Q:How much is the manual installation fee of ductile iron pipes from 100 to 150 per metre?
DN150 ductile iron water supply pipe installation interface is not the same way, the installation of labor costs will be somewhat different
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 disadvantage of nodular cast iron in excess of silicon?
Excessive silicon control results in the formation of nodular graphite in large cross section ductile iron and reduces the mechanical properties of castings.
Q:Which direction should the spigot of the K9 ductile iron pipe be installed?
Ductile iron pipes mainly called centrifugal ductile iron pipe, it has the properties of nature, iron and steel, excellent corrosion resistance, good ductility, good sealing effect, simple installation, mainly for municipal, industrial and mining enterprises, water supply, gas, oil etc.. Water supply pipe is the first choice, with high cost performance.
Q:How can 4 inch ductile iron pipe be connected with 2 inch galvanized pipe?
The hot dip galvanized welded steel pipe galvanized pipe, galvanized pipe by welding without taking anti rusting measures (furnace welding and welding) steel pipe, seamless steel pipe or other metal pipe of the clarinet, process of hot dip galvanizing, the outer coating and galvanized layer to long-term corrosion of the steel pipe after processing.
Q:Why is the cast iron tube lined with cement? Under what circumstances are ductile iron pipes lined with cement, and under what circumstances do not have to be lined with cement?
Cement lining to protect water quality, reduce loss, improve the service life of the pipeline ductile, ductile iron pipes are generally lined, which the en545 standard specifies the quality of what kind of what kind of cement.
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.
