Q:Can cast iron pipes not be used for domestic water supply and drainage?
Cast iron pipes are mostly used in fire fighting, fire hydrant water supply and indoor water supply. Plastic pipes are used in general and high water riser pipes are made of plastic steel composite pipes
Q:How to properly maintain FRP pipes
Length of single pipe lengthReduce pipe connection, speed up installation, improve the quality of the whole pipeline.
Q:Qianwei County ductile iron pipe which tool to use cutting convenience?
The cutting of ductile iron pipes is usually done by mechanical cutting, and the working intensity of the machine is stronger than that of our normal workers. This cutting method can effectively reduce the labor intensity of workers, and ensure the quality of cutting. There are many different ways in mechanical cutting, such as sawing, grinding, cutting, and cutting with an electric wire cutter.
Q:The role of chromium in nodular cast iron
Chromium has better strengthening and toughening effect in nodular cast iron. Chromium containing cast iron has the characteristics of high strength, high elongation, high impact value and low hardness.
Q:What are the meanings of cast iron pipe wall thicknesses LA, A and B respectively?
According to its manufacturing methods can be divided into: sand, centrifugal pipe, straight pipe, continuous cast iron pipe and sand pipe.According to the material used, it can be divided into gray iron pipe, nodular cast iron pipe and high silicon iron pipe.1 、 water supply cast iron pipe:The use of cast iron cast iron water pipe of No. 18 above by adding nodulizer, after centrifugal ductile cast iron pipe by centrifugal casting machine, the performance of ductile iron pipe with nature, iron and steel, excellent corrosion resistance, good ductility, good sealing effect, simple installation, mainly for municipal, industrial and mining enterprises water, gas, oil etc.. Water supply pipe is the first choice, with high cost performance.2 、 sand casting centrifugal cast iron pipe:The sand casting centrifugal cast iron pipe is made of gray cast iron. It is suitable for the transportation of pressure water such as water and gas.
Q:Usage of ductile iron pipe expander
Ductile iron expansion is mainly provided with large flexible, easy installation, the product main material for nodular cast iron, nodular cast iron is mainly through spheroidization and inoculation by spherical graphite, effectively improve the mechanical properties of cast iron, especially the plasticity and toughness increased, resulting in higher than the strength of carbon steel. The material mainly has high strength of plasticity and toughness, and its development at home and abroad is very fast, the output has exceeded cast steel and malleable cast iron, become second only to gray cast iron casting alloy material. Spheroidal graphite is obtained by spheroidizing and inoculation of nodular cast iron. It can effectively improve the mechanical properties of cast iron, especially improve the plasticity and toughness, so as to obtain higher strength than carbon steel.
Q:Is the cast iron pipe buried in need of antiseptic treatment? What kind of anticorrosive materials are used?
It must be antiseptic. Usually hot asphalt brush painted two times, winding glass fiber cloth two road, cross construction.
Q:General cast iron prices now
Hubei, Suizhou, in 2010, normally 5000-7000 tons of iron, if required to join copper and other metals, the price is calculated. The price is very low, because the market price in Suizhou is the lowest in the whole country. Under normal circumstances, it should be 8000 tons a ton
Q:What is the wall thickness of K10 grade dn=400 ductile iron pipe?
Ductile iron pipe is a kind of cast iron. It is an alloy of iron, carbon and silicon. Graphite is exist in spherical form, usually graphite size is 6-7, casting spheroidization grade control requirements for 1-3 quality (spheroidization rate greater than 80%), so the mechanical properties of the material itself has been improved, has the essence of iron, steel performance. The annealed ductile iron pipe is composed of ferrite and pearlite. The mechanical properties of the ductile iron pipe are better.
Q:Is the crankshaft material forged or ductile iron?
Cast iron can not be forged, only steel, malleable iron can not be forged, only the crankshaft is particularly hot, can not meet the strength of the hardening when forging
