Q:How big is the seamless steel tube of DN50?
Domestic steel pipe diameter is generally divided into A series and B series, DN50 pipe diameter of 60mm and 57mm respectively, the wall thickness should be based on your design pressure, temperature, pipe material to calculate.
Q:Difference between seamless steel pipe and welded pipe
Welding pipes can be used in water pipelines, gas pipelines, heating pipes, electrical appliances, pipelines and so on.
Q:Is the steel frame on each floor supporting formwork (floor) called full scaffolding?
The use of scaffold as its height, when the ceiling height below 3.6M, no matter what the ceiling decoration, decorative scaffolding are calculated
Q:How to make the internal tooth of the steel pipe?
At present, in our country, 300MW or 600MW or more large capacity sub critical and supercritical thermal power boilers are designed or imported abroad. Membrane internal wall tubes are widely used in membrane water wall.
Q:What is ND steel pipe?
ND steel also has the ability to resist chloride ion corrosion. ND steel pipe, the main reference indicators (70 degrees Celsius, 50%H2SO4 solution immersion 24 hours), and carbon steel, Japan imported similar steel, stainless steel corrosion resistance compared to higher than these steel grades. Products by domestic refineries and manufacturing units after the use of widely acclaimed, and achieved good results.
Q:The plastic pipe and steel pipe difference
In the plastic coated galvanized steel pipe inside the plastic coated manufacturing method. The thickness of the internal plastic is thin, which is equal to a plastic skin.
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:What does GALV mean in a steel tube?
Steel tube (Steel pipe) production technology development began in the bicycle manufacturing industry, the rise of the early nineteenth Century during the oil development, the two world war ships, boilers, aircraft manufacturing, manufacturing of power boiler after the Second World War, the development of chemical industry of petroleum and natural gas drilling and transportation, will effectively promote the the yield and quality of varieties, the development of steel tube industry.
Q:What's the difference between round and round tubes?
Round steel is generally refers to steel, the surface is not threaded, different from round steel pipe, round tube is round tube.
Q:What kind of argon arc welding wire is used for 16Mn steel pipe?
16Mn steel weldability is very good, general use TIG with J50 welding wire, hand arc welding with J506, J507 and other welding rod
