Q:It's not easy to drill ductile iron with cobalt high speed steel bit. Please help to point it out
Choose carbide or whole carbide drill, about 90HRC in hardness. But it requires a high number of drills, around 3000.
Q:Can ductile iron be welded? Is weldability comparable to gray iron?
Nodular cast iron welding can be determined, this should be in some high strength cast iron equipment used more, the tensile strength of normally ductile cast iron welding in welding is higher, is worse than the grey cast iron, it is actually very difficult to distinguish with the naked eye is ductile iron or cast iron the iron in the repair equipment, we usually use WE777 special cast iron electrode universal wide welding, but it is only for maintenance use, the effect is really good, reducing the risk of cracking and high strength welding rod matching to ensure the strength of welding.
Q:Qianwei County ductile iron pipe which tool to use cutting convenience?
Cutting the ductile iron pipe by grinding is grinding and cutting the ductile iron tube continuously by grinding wheel until it breaks. To cut ductile iron pipes by grinding cutting method, the cutting parts should be crossed at first so as to avoid deviation during cutting. Place the drawn ductile iron tube in the cutting machine and fix the ductile iron tube and clamp it with a built-in clamp. Next, start the cutting machine and gradually press the handle of the cutting machine. The grinding wheel cuts into the ductile iron tube until the ductile iron pipe is cut off. When exerting pressure on the handle, do not force too hard at once, otherwise it will cause the grinding wheel to break. In the operation of the machine, the operator must not stand on the side of the grinding wheel, so as to avoid accidents. When the wheel appears in cutting, vibration, shaking, uneven phenomenon, should immediately stop the operation, check whether there is the wheel gap, if damaged, must be promptly replaced, to ensure safety and normal. Good cutting ductile cast iron pipe section, if there is to prevent the use of burrs, can be removed by grinding or machining file.
Q:What are the specifications for the installation of water ball iron pipes?
Trench excavation: the width of the groove should be pressed by the meter: B=D1+2 (b1+b2). Type B: the width of excavation at the bottom of the pipe groove (mm) D1 the width of the outer edge of the pipe structure (mm) B1 - the width of the face of the pipe side (mm) B2 - the support width of the side of the pipe (mm).
Q:What does "K8" mean in ductile iron pipe grades?
1 ductile iron pipe grade K8, on behalf of the ductile iron 8 grades, K refers to the wall thickness coefficient, the higher the grade, the greater the pressure, the lower the level, the less pressure to bear.2 wall thickness calculation formula: e=K (0.5+0.001DN).
Q:What are the interface forms of ductile iron pipes? The best drawings are available. Thank you
Because of this interface and the corresponding T sealing aprons can withstand greater deflection angle and greater tolerances, especially suitable for unstable formations and corners.
Q:How can the ductile iron pipes be treated with corrosion protection?
Cement mortar lining + special coatingThe internal corrosion prevention measures are suitable for pipes conveying sewage, and the corrosion resistance of lining can be improved.
Q:Classification of cast iron pipes
Continuous cast iron straight pipe:Continuous cast iron pipe, namely continuous casting gray cast iron pipe, suitable for water and gas pressure fluid delivery.
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:Method for cutting large diameter ductile iron pipe
When the volume ratio of oxygen and acetylene is less than 1, a carbonized flame is obtained. Because of less oxygen and incomplete combustion, the flame is longer than the neutral flame and the temperature is lower. Acetylene in the carbide flame is suitable for welding high carbon steel, cast iron and cemented carbide materials. When welding other materials with a carbide flame, the weld metal becomes hard and brittle.
