Q:How long are the seamless tubes? Are they six meters long?
The length of the seamless tube is 3000~12000mm, including 6 meters.
Q:Seamless steel tube with the tube with what is the difference?
Seamless pipe can withstand ultra-high pressure, of course, its wall thickness will increase, which needs to be designed according to pressure requirements. It is generally used in high-pressure oil pipes, boiler tubes and other high temperature and high pressure equipment. There are also seamless tubes for structural purposes, depending on the design requirements.
Q:What's the actual size of the DN25?
Steel pipe production technology development began in the bicycle manufacturing industry rise, 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, petroleum and natural gas drilling and mining and transportation, are promoted in production the quality and variety, the development of steel tube industry.
Q:Why can't stainless steel be put together with carbon steel tube?
Stainless steel can not be put together with carbon steel because of galvanic corrosion
Q:Difference between cold rolled steel pipe and common steel pipe
From the above point of view, the hot rolled steel pipe used in fluid transport, mechanical structure and other requirements of the size of the situation is not high, cold-rolled steel pipe used in precision instruments, hydraulic systems, pneumatic and other places demanding.
Q:How to make the magnetic steel, can be like a magnet?
Magnetization. Winding the insulated wire on the object, passing in the direct current, and taking it down after a period of time.
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:How long is the seamless tube?
Welded pipe is generally 6912 meters fixed length, seamless pipe on the market in general non fixed foot, but usually more than 6 meters
Q:What is the weight of hot galvanized steel tubes? DN150 4mm wall thickness
GB/T3091-2008: DN150 welded steel pipe, wall thickness of 6mm, the theory of the weight of welded steel pipe 24.02kg/m, galvanized steel pipe should be multiplied by the weight coefficient after galvanizing, C, DN150, wall thickness of 6mm, C=1.02, DN150, theoretical weight and wall thickness of 6mm galvanized steel 1.02*24.02= 24.5kg/m.
Q:DN150 welded steel tubes one meter multiple
DN150 welded steel pipe according to the thickness of two specifications: outer diameter 165mm, wall thickness 4.5mm, 17.81Kg per meter weight, wall thickness of 5.5mm, 21.63Kg. per meter weight
