Q:What material is RHS in the steel tube?
RHS is a rectangular hollow section steel. The RHS structure represents a rectangular hollow section steel.
Q:What kind of argon arc welding wire is used for 16Mn steel pipe?
JB/T4709 recommends H10MnSi, but H10MnSi allows a lower value of strength of 430MPa, which does not match the parent material. I think American Standard is selected according to the selection of welding wire ER70S-6 GB ER50-6 wire can guarantee the equivalent strength of parent materials, and Si, Mn content can also guarantee the deoxidation effect, the weld joint is not easy to produce pores.
Q:The difference between 12Cr1MoVG alloy steel tube and 15CrMo
12Cr1MoVG is a kind of material for alloy tubes. The main purpose is to make the steel structure in the boiler, the use temperature of 580 degrees, requiring high temperature resistance steel plate, durable strength, steel plate in the normalized and tempered state delivery. 12Cr1MoV alloy tube is based on high quality carbon structural steel. It is appropriate to add one or more alloy elements to improve the mechanical properties, toughness and hardenability of steel.
Q:How to distinguish seamless pipe and welded pipe?
If it is seamless pipe, the port can be seen inside and outside the pipe there is no welding meat exists, and even if the welding pipe welding processing, the pipe weld is very easy to observe.
Q:Outside diameter 60, thickness 3.5 seamless steel tube, how many kilograms per meter?
Other commonly used theoretical weight formulas per metre:Thread steel (Kg/m):W=0.00617 * D * D, D - sectional diameter (mm)Fang Gang (Kg/m):W=0.00785 * a * a, a - edge width (mm)Flat steel (kg/m):W= 0.00785 * b * D, B -- edge width (mm) d - thickness (mm)Round steel rod (kg/m),:W= 0.006165 * D * D, D - diameter (mm)
Q:What does GALV mean in a steel tube?
GALV is the abbreviation of English galvanized (Galvanized), which means galvanized steel pipe.
Q:Will the steel tube dance?
Pole dancer performing double pole dance performance is much higher than single pole dancing difficult, because not only refers to the double pole dance together the two pole dance, two people should pay attention to the dance and tube movement, if two people do not fit to dance moves and skills on the tube action, you jump you. I jump, that wasn't a real double pole dance, dance like a double tube. If the two dance movements and pipe movements are not good enough or not natural enough, they will destroy the effect of the whole dance and make the audience feel that the dance is chaotic and not beautiful, so it is better to see a single pole dance. But the dancer's double pole dance performance is good, more powerful than single pole dance, and more aesthetic and artistic.
Q:Are steel tubes and round steel in weight or length when purchased?
The price must be measured by weight, and the length, volume and other specifications should be entered
Q:Seamless steel tube DN15 specification phi 18*3 what do you mean?
Seamless steel pipe DN15 specification phi 18*3 refers to 3 outer diameter of 18mm B type DN15 seamless steel tube.
Q:What's the difference between a cracked carbon steel tube and a liquid carbon steel tube?
Test: cracking carbon steel pipe in addition to eddy current testing, but also to do ultrasonic testing, and liquid carbon steel tubes are generally only eddy current testing.
The company has successively passed ISO9000 quality system, the American Petroleum Institute API, and also earned the environment healthy license, national special equipment manufacturing license.
