Q:The difference between cast iron pipe and ductile iron pipe
Ductile iron is based on the cast iron to change some of the characteristics of the structure of iron, so that it has become a lot of toughness, than the cast iron pipe is too brittle shortcomings much better, the tensile strength of the pipe bending strength greatly improved. The sealing material used in the socket interface is rubber ring.
Q:Can ductile iron pipes be made into clear tubes?
Of course, the cast iron pipe is suitable for being buried in the ground because of its corrosion resistance, rust resistance and non deformation.
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.
Q:Can cast iron pipes not be used for domestic water supply and drainage?
Yes, the main use is, outdoor water supply pipe can be PE or ductile iron (socket connection). Indoor water is now used in general plastic pipes, but in the past seems to be able to use ductile iron, as for drainage, generally do pressure type drainage, when the choice is cast iron pipe. There are also indoor fire pipes using welded steel tubes or ductile iron.
Q:What are the differences between cast iron pipes W and A?
W type socket cast iron drainage pipe made of stainless steel flexible clamp connection in the construction of the installation; A type cast iron drainage pipe with flexible flange and sealing ring connection in the construction of the installation; B type cast iron drainage pipe comprehensive advantages of W type and A type cast iron drainage pipe, straight pipe part adopts W type bearing mouth of pipe, pipe fittings with double flange structure;
Q:Ductile cast iron can replace copper sleeve
Although the ductile cast iron with lubrication, but no lubrication or copper sleeve, Rongchang graphite copper sleeve, with self lubrication with high strength copper alloy (CuZn25Al5, CuZn24Al6Fe3Mn4) as the basic material, according to the use conditions according to a certain proportion in the work surface processing hole and fill in the solid lubricant, high strength copper alloy provide a high bearing capacity and solid lubricant can form low friction.
Q:What effect does magnesium play in nodular cast iron?
Magnesium is played by spheroidizing.Nodular cast iron is added a certain amount of spheroidizing agent (magnesium or rare earth magnesium alloy) to the paste before casting, so that all or most of the carbon is spherical graphite and is distributed on the base.
Q:What kind of valves are commonly used in ductile iron pipes?
Gate valve, butterfly valve, globe valve, check valve flange of various valves, (but the pipeline used for water supply and some limitations of the transport medium may be prescribed valve type) now due to material improvements in the technology, in most cases, smaller pipe diameter is also large diameter pipe outlet valve, butterfly valve, because of the pipeline the large diameter pressure in the pipeline and water than the small caliber to open and close the valve, to human hard, efficiency is not high, so for butterfly valve,
Q:What is the acceptance of cast iron pipe material?
Specific acceptance, first of all in line with national standards, followed by the provisions of the contract, and then the project requirements. General contract and drawings will have the requirements and standards of pipe. I hope I can help you.
Q:Some questions about the bearing capacity of nodular cast iron pipes!
The pipe diameter is D, the tube thickness is T, and the internal bearing pressure P is related to the yield limit [S] of the pipe:PD=2T[S]Or [S]=PD/ (2T)If the P=3MPa, D=300mm and T=6 mm are substituted, the pipe yield limit should be given[S]=3*300/ (2*6) = 75 MPaI think the ductile iron pipe's yield limit should be greater than this value. Factory production should be all right. Only ductile iron pipe production, low product specifications, prices are higher.
