Q:What is the outer diameter and wall thickness of DN40 steel pipe?
DN40, refers to the diameter of 40mm, that is, an inch and a half, there are welded pipe and galvanized pipe,Ordinary wall thickness 3.5mm wt 3.84kg/mThicken 4.25mm weight 4.58kg/m
Q:Which is better, galvanized steel pipe or stainless steel?
Most of the use requirements are to maintain the original appearance of the building for a long time. In determining the type of stainless steel to be chosen, the main consideration is the aesthetic standards required, the corrosivity of the atmosphere in the area, and the cleaning system to be adopted. However, other applications increasingly seek only structural integrity or watertightness. For example, the roof and side walls of industrial buildings. In these applications, the construction cost of the owner may be more important than the aesthetic, the surface is not very clean can also. The use of 304 stainless steel in a dry indoor environment is quite effective.
Q:Can the KBG25 steel tube hold 4 six types of cables?
Over five types of cables, the outer cross section is about 24 square millimeters, over six types of network cable for the outer cross section of about 35 square millimeters, so 35*4/490=28.57%, far more than 20%. Therefore, according to the norm, only 3 super six categories can be worn. If the distance is short and the joint is not enough, it can be laid like this, but it does not conform to the construction standard
Q:The difference between 12Cr1MoVG alloy steel tube and 15CrMo
With this kind of steel manufacturing products, usually by heat treatment (normalizing and tempering); parts made before use, usually need to go through refining or chemical surface treatment (carburizing and nitriding), surface quenching or high-frequency quenching treatment. Therefore, according to the chemical composition (mainly carbon content), heat treatment process and use of different, such steel can be roughly divided into carburizing, quenching and tempering and nitriding steel three.
Q:What is the difference between galvanized iron pipe and galvanized steel pipe? Or called different, in fact, is referred to as galvanized pipe?
Different materials, cast iron, steel seamless steel pipe; the different production process, cast iron is hot metal casting, steel rolling mill of seamless steel tube is through processing, different performance indexes, ductile iron diameter, wall thickness, crisp texture, relatively heavy, can be made of seamless steel pipe diameter is very small, the wall is very thin, good toughness, light. Cast iron, cheap, but the bottom of the strength, can only be used in low pressure occasions.
Q:What is the theoretical weight per square meter of the steel pipe diameter of the outer frame and the thickness of the tube wall 3mm 48mm?
Dimensions of ordinary steel tubes (taken from GB/T 17395-1998)The theory of weight / (kg/m) | wall thickness (2.9 3.0mm: 3.33)
Q:What's the difference between hot-rolled seamless steel tube or cold-rolled seamless steel tube?
Cold rolled seamless steel pipe (DIAL) in general, steel pipe for low and medium pressure boiler tube, high-pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, oil cracking tube and other steel tube, including carbon thin-walled steel, alloy thin-walled steel, stainless steel, thin steel tube.
Q:How much is 4 inches steel tube MM?
Seamless root weight per meter: 1 mm (diameter - thickness) * wall thickness of *0.02466*1 meters is? Normal KG/M pipe length 8-11rice
Q:Where is the difference between seamless steel pipe and welded pipe?
In appearance, seamless steel pipe and welded steel pipe difference in the welded pipe wall welded tendons, and seamless No.
Q:What does "SC50" steel pipe mean in civil engineering?
The corrosion resistance of Ni is very strong in acidic environment. In the environment containing sulfuric acid or hydrochloric acid, the higher the content of Ni in the welded pipe is, the stronger corrosion resistance is. In general circumstances, the addition of Cr in a T-junction steel pipe prevents erosion. The marginal condition of the steel strip is another important cause of the wrong edges. The influence of mass flow rate, heat flux density and structural parameters (ratio of spiral curvature diameter and diameter of T-shape welded tube Dc/D) on heat transfer coefficient of saturated bubble boiling in vertical helical tubes.
