Q:What is the excavation width of ductile iron pipes with diameters greater than 1400?
Then, according to the soil characteristics, different slopes are calculated, and the width of the excavation is calculated according to the depth and slopeIf the soil is soft, high water content and easy to collapse, the excavation width will be wide, otherwise the slope will be steep and the excavation width will be narrow
Q:Method for cutting large diameter ductile iron pipe
When the ratio of oxygen to acetylene is 1 to 1.2, the flame produced is called neutral flame, also known as normal flame. It consists of flame core, inner and outer flame: near the welding nozzle at the flame core, a bright white; followed by the flame, a blue purple, the highest temperature, about 3150 DEG C, from the front cone at 2 ~ 4mm, and the application of welding wire to the workpiece; the outer flame is orange red. Neutral flame is a flame commonly used in welding. It is used to weld low carbon steel, medium carbon steel, alloy steel, copper and aluminum alloy.
Q:What's the difference between grey cast iron pipe and ductile iron pipe?
Ductile iron is close to medium carbon steel and is much cheaper. Vermicular graphite iron is the best, but grey iron is worse and white iron is the worst. Therefore, the quality of ductile iron pipe with better quality and price is superior to other cast iron pipe fittings.
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:Ductile iron pipe joint damage, water leakage, want to see the connection with other pipe fittings, how to operate?!
The ink tube is really not good. Oh, have you tried blocking it with cement or plugging it with putty?Just pick up PE haha
Q:What does ductile iron pipe "ND200" mean?
The nominal pipe diameter and the inner diameter and the outer diameter were not equal, for example: the nominal diameter of 100MM seamless steel pipe 102*5, 108*5 several, 108 for the outer diameter of pipes, 5 said that the wall thickness of the tube, therefore, the pipe diameter (108-5-5 = 98MM), but it is not completely equal to pipe diameter minus two times the wall thickness difference, it can be said that the nominal diameter is close to the diameter, but not equal to the diameter of a pipe diameter specifications on the design drawings, so we use the nominal diameter, the purpose is to determine according to the nominal diameter pipe, flange and gasket structure and size connecting dimensions, nominal diameter is represented by the symbol DN, if the diameter of said in the design drawings, piping specifications should also make the table, show that the nominal diameter of a pipe wall thickness.
Q:What is a slide in type T flexible interface?
There are many kinds of cast iron pipe interface. The commonly used interfaces include sliding type (T type) flexible interface, mechanical type (K type) flexible interface, mechanical type (NII type, SII type) flexible interface, flange type interface and special interfaceSliding type (T type) flexible interfaceSlide type (T type) flexible interface as shown below. The ductile interface is widely used in the DN I000mm following the cast iron pipe, has the advantages of simple structure, convenient installation, good sealing characteristics. In the socket structure considering the location of the rubber ring and the deflection angle, this interface can adapt to deformation a certain foundation, has certain anti vibration ability, at the same time using the deflection angle of the long distance pipeline to achieve steering.
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?
The cement lining protects the water quality, reduces the head loss and improves the service life of the spheroidal graphite pipe. As long as the water delivery hose is used, the cement lining must be used. There is no lining cement for conveying air.
Q:What's the difference between cast iron pipe and steel pipe?
Steel pipe is not only used to transport fluid and powder solid, exchange heat energy, and manufacture mechanical parts and containers, but also is an economic steel. It can reduce weight and save 20 to 40% of metal by using steel pipe to make building structure, network frame, prop and mechanical support. Moreover, it can realize factory mechanization construction. Using steel pipe to manufacture road bridge can not only save steel, simplify construction, but also greatly reduce the area of coating protective layer, save investment and maintenance cost.
Q:Will the quality of ductile iron shrink?
Fool you. It is normal that the surface shrinks and goes down, but it can not be said to be good.
