Q:What is the single length of galvanized steel pipe?
The single length of galvanized pipe is 6 meters. The length of galvanized seamless steel tube is uncertain, depending on the length of seamless steel tube.
Q:What's the difference between No. 20 steel pipe and 27SiMn Steel Pipe?
27SiMn =27 - steel pipe, which is a seamless steel tube material, the carbon content in 0.24 - 0.32%, SIMN single because it five elements (carbon manganese silicon Si, C, Mn, P P, S, guimeng sulfur) the high content of about 1.10 - 1.40%.
Q:Is steel pipe made of profiles?
According to the shape of the cross-section, the steel is generally divided into profiles, plates, pipes and metal products in four categories.Therefore, the steel pipe belongs to the pipe, not the profile.
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:Does seamless steel tube have a bend of 135 degrees?
In engineering, it is usually marked as "45 elbow" and has no "135" mark. The angle of the elbow is acute, so there will be no more than 90 degrees elbow.
Q:How to calculate the maximum bending stress of steel pipe? Is there a list of the maximum flexural normal stresses for steel pipes of different materials and diameters?
The maximum flexural normal stress is calculated as: Sigma =M/ (gamma x*Wnx).Of which: M is the maximum bending moment of the steel tube;Gamma X - the plastic development coefficient of the cross section; for the cross section of the steel tube, 1.15,
Q:How to make the steel pipe spray paint is not easy to fall off?
First you will rust steel, to clean, good quality alkyd rustproof paint, completely dry after brushing paint, color to see his kind of love.
Q:Can stainless steel pipes spray black paint?
Yes, after painting, I usually touch hands and paint off in 2 years or so
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:How seamless steel tube is formed?
Seamless steel tubes are formed by cold drawing and hot rolling.
