Q:What are the differences between cast iron pipes W and A?
W cast iron pipe is subdivided into W cast iron pipe and W1 cast iron pipe, the difference between them is the difference between the wall thickness. Because of the cold weather, the requirements for pipes are higher. The W cast iron pipes are mainly used in the north, while the W1 cast iron pipes are mainly used in the south.
Q:What kind of valves are commonly used in ductile iron pipes?
You ask the ductile cast iron valves used on no special, because this interface in connection with the valve on the pipe flange is basically, as long as the flange of the valve should be can be used in milling pipe.
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:What's the difference between ductile iron pipe and cast iron pipe?
Ductile iron pipe is based on cast iron, changed 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:Ductile iron and gray iron is what are the advantages and disadvantages of it
Comparison of nodular cast iron and cast steelThe strength of nodular cast iron is comparable to that of cast steel. Ductile iron has higher yield strength, the lowest yield strength is 40K, while the yield strength of cast steel is only 36k. In most municipal applications, such as water, brine, steam, ductile iron has more corrosion resistance and oxidation resistance than cast steel. Because of the spheroidal graphite microstructure of nodular cast iron, nodular cast iron is superior to cast steel in reducing vibration ability, so it is more beneficial to reduce stress. An important reason for choosing ductile iron is that ductile iron costs less than cast steel. The low cost of ductile iron makes this material more popular, more efficient and less costly for ductile iron.
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:What is the difference between spheroidal graphite cast iron QT400-15 and QT400-15A? What does the A mean later?
This should be said in front of the material, and later add A, should refer to the grade
Q:What is the K9 standard pressure for ductile iron pipes?
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.
Q:Can centrifugal cast iron pipe be galvanized or coated with asphalt which is good for corrosion prevention?
The centrifugal ductile iron pipe has the advantages of zinc coating and asphalt coating, and it is used in combination with two. By spraying zinc and epoxy coal tar coating of ductile iron pipe wall (or epoxy resin paint, polyurethane, etc.) wall using Portland cement (or epoxy powder, epoxy, polyurethane, ceramics etc.) wall coating can effectively active substances in soil and the formation of an insoluble zinc salt protection tube, the internal coating can inhibit corrosion of pipe body fluid medium.
Q:Is ductile iron pipe breakable?
5, inferior wood surface is easy to produce cracks, because its billet is adobe, Adobe porous, Adobe in the process of cooling due to the role of thermal stress, cracks, after rolling, there are cracks;6, poor drainage tube appearance often pitted phenomenon. Pits is due to groove wear caused by defects in pipe surface irregular uneven. Because of the poor sewer pipe manufacturers to pursue profits, often rolling groove rolling most standard.Ductile iron pipes are broken because of the excessive heat treatment during casting or the lack of proper addition in casting to prevent a change in the proper brittleness and to cause cracking. It is recommended that you used to repair defects of cast iron machine, are currently on the market to sell, but also can ensure welding intact appearance, make your products by quality, but if it is in the use of performance can not meet the effect, especially the pipeline pressure quite big, what methods are of no use that must be re cast as the new.
