Q:How much is the tube?
The theoretical weight calculation formula of ordinary carbon steel tube is:The weight of each meter is kg/m= (outer diameter mm-, wall thickness mm) * wall thickness mm*0.02466For example: inventory 20# pipe diameter of 108*4.5 weight per meter:Kg/m= (108-4.5) *4.5*0.02466=11.485In accordance with the diameter of 108*4.5 steel pipe market price is 4500 yuan / ton as an example, we can know the diameter of 108*4.5 steel pipe per meter price: 11.485*4.5=51.68 yuan.
Q:How can galvanized steel pipe be connected with stainless steel pipe?
Welding methods are used to connect. Because galvanized pipe is in fact carbon steel pipe, so galvanized pipe and stainless steel pipe welding, in fact, carbon steel and stainless steel welding, welding of dissimilar materials.
Q:25 of the steel pipe with 6 in charge of what is the difference?
25 of the steel pipe with 6 in charge of the difference:25 of the steel pipe refers to the DN25 tube, the outer diameter of 25mm; 6, in charge of refers to DN20 steel pipe, the outer diameter is 20mm.
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:How to descaling galvanized steel pipe?
If the substrate is rusty, rust removal can be removed by acid leaching. If the coating is rusted, it can also be dipped in acid, but this will also remove the coating and make the base material more susceptible to rust, preferably by re plating and passivation
Q:Which is cheaper, angle iron or steel pipe?
Angle called angle, the steel strip is perpendicular to each other on both sides into the corner. There are equal angles and unequal angles. The two sides of an equal angle steel are equal in width. The specifications are expressed in millimeters of edge width * edge width * edge thickness. Such as "/ 30 x 30 x 3", that is 30 mm width equal angle, edge thickness of 3 mm. Also available models that model is the number of centimeters wide, such as angle 3#.
Q:Which is more load-bearing, the same thickness of steel pipe and steel bar?
The same length, the same pipe diameter, the same material strength is hollow, the ratio of area of steel (solid), and the cyclical and slender radius smaller than the larger, so the longitudinal stability coefficient is smaller, three factors, two factors are weak in steel reinforced, another factor: strength, they are the same, no doubt, steel reinforced bearing less than.
Q:What quota should be installed for heating seamless steel pipe?
Seamless steel pipe having a hollow cross section, used as a conduit for conveying fluids, such as pipelines for transporting petroleum, natural gas, gas, water, and certain solid materials.
Q:What do you mean by "SC" in welded pipe SC200? What's the diameter of 200?
SC in principle, it should be called water gas pipe, also called thick wall steel pipe;
Q:Seamless steel pipe 8162 and 8163 what is the difference?
8163 GB is fluid delivery tube, need to use eddy current detection, fluid transport, liquid, gas, solid, such as natural gas, water, gas, coal and stone, 8162 and 8163 of the popular point that is 8163 more than 8162 senior, 8163 inspection, 8162 inspection. I hope you understand!
