Q:How to control mortar proportioning in ductile iron pipe cement coating
The calculation steps are: first to calculate the amount of plastering engineering (area), and then check the "national construction basic quota" quota in the corresponding amount of mortar project, engineering quantity multiplied by the amount of mortar that fixed amount of mortar, the mortar amount multiplied by the corresponding mix ratio of mortar, the consumption of raw materials can be obtained.
Q:What is the relationship between the installation direction of the ductile iron pipe and the direction of flow?
The use of cast iron by adding more than 18 nodularizer, after centrifugal ductile cast iron machine high speed centrifugal cast pipe, called "ductile" (Ductile Cast Iron Pipes), referred to as ball pipe, ductile iron pipe and ductile iron pipe etc.. The utility model is mainly used for conveying water, and is an ideal choice for tap water pipes.
Q:What does ductile iron pipe "K" mean?
The higher the K level, the better the quality, and the national standard requires K9
Q:What is the exterior anticorrosion of nodular cast iron pipes?
According to the national standard GB/T13295-2008, external corrosion prevention technology of ductile cast iron pipe is coated with asphalt paint, spraying zinc, widely used in domestic manufacturers is spraying zinc spraying asphalt layers corrosion, zinc layer thickness: 130 grams / square meters, the thickness of asphalt 75Um.
Q:Ductile iron gears are generally treated without heat treatment
Heat treatment must be necessary, generally annealed first to machine, after quenching or nitriding treatment
Q:What is the relationship between the mechanical properties of spheroidal graphite cast iron and its spheroidization rate?
Poor balling and poor performance. Can do under tensile. General level three or four or more on it
Q:The difference between ductile cast iron pipe and machine-made cast iron pipe
Different appearance, ductile iron pipe single length of 6 meters, large wall thickness; mechanism cast iron pipe single length of 3 meters, the wall thickness is thin.
Q:The difference between spheroidal graphite cast iron pipe and HDPE water supply pipe
(4) HDPE pipes do not need corrosion protection. If the water supply pipeline is made of ductile iron pipe, the inner and outer walls of the ductile iron pipe shall be treated with corrosion protection.(5) the normal service life of the ductile iron pipe is 20~25 years after the pipe is treated by inner and outer walls. The HDPE tube has no corrosion, and the normal service life is 50 years.
Q:How can the ductile iron pipe be welded?
The nickel electrode cold welding, such as Z408
Q:Is the ambient temperature at minus 20 degrees better with grey cast iron or ductile iron?
Heavy thermal and mechanical shock, high temperature or low temperature, corrosion resistance and dimensional stability. To meet these changes in use conditions, ductile iron is available in many grades, providing a wide range of mechanical and physical properties.
