Q:What's the difference between a rectangular tube and a rectangular steel tube?
Rectangular tube is a kind of hollow long strip steel, also known as flat tube, flat square tube or square flat tube (Gu Mingsiyi). A large amount of pipe used to transport fluids, such as petroleum,Natural gas, water, gas, steam, etc., in addition to bending and torsional strength of the same weight is lighter, so it is also widely used in the manufacture of machinery parts and engineering structures. It is also used to produce all kinds of conventional weapons, guns, shells and so on.
Q:What kind of argon arc welding wire is used for 16Mn steel pipe?
16Mn steel belongs to carbon manganese steel, the content of carbon is about 0.16%, and the yield point is equal to 343MPa (strength grade is 343MPa). 16Mn steel alloy content is less, good weldability, welding generally without preheating. But because the 16Mn steel hardened tendency is slightly larger than the low carbon steel, so at low temperatures (such as winter outdoor operations) or welding in high rigidity, large thickness of the structure, in order to prevent the cold crack, need to take measures to preheat.
Q:Can the KBG25 steel tube hold 4 six types of cables?
The specification specifies that the duty ratio of multiple conductors through the pipe laying shall not exceed 20%, and the straight-line distance shall not exceed 30 meters. The distance shall be shortened by the elbow, and the specifications or handbooks can be checked in detail
Q:Outside diameter 60, thickness 3.5 seamless steel tube, how many kilograms per meter?
Steel tube Kg/m (including seamless steel tubes and welded tubes) theoretical formula per meter weight: W=0.02466 * S * (D-S)Of which: S - wall thickness (mm), D - steel tube diameter (mm), W - kg / M
Q:Fastener type steel pipe scaffold external parts name
Steel pipeScaffold steel pipe should adopt outer diameter 48mm and wall thickness 3.5mm welded steel pipe, also can use outer diameter 51mm and wall thickness 3.1mm welded steel pipe. For horizontal horizontal rods, the maximum length of steel pipe shall not be greater than 2m; other poles shall not be greater than 6.5m, and the maximum mass of each steel tube shall not exceed 25kg, so as to be suitable for manual handling.
Q:What is the single length of galvanized steel pipe?
Galvanized steel pipe is divided into cold galvanized steel pipe, hot galvanized steel pipe, cold galvanized steel pipe has been banned, and the latter is also advocated by the state for the moment, can be used. In 60s and 70s, developed countries began to develop new types of pipes, and galvanized pipes were banned.
Q:How can two smooth steel pipes be joined? The size of the two pipe is different (except for welding)
Fastener type steel pipe scaffold, fastener is the connection between steel pipe and steel pipe, and its form has three kinds, namely right angle fastener, rotating fastener, butt fastener
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:What is the process of spiral steel tube production?
1. open panel inspection: after the steel plate is opened, the product line is entered, and the ultrasonic examination of the whole plate is carried out first.2., flat milling: through the anvil machine to make the original coiled steel flat, and then through the milling machine on the edge of the steel plate two sides milling, so as to achieve the required plate width, plate edge parallelism and groove shape.
Q:Who knows what is the difference between double submerged arc welded pipe and longitudinal submerged arc welding?
Double submerged arc welding should be for spot welding and single side welding, they are straight line welds, but double submerged arc welding seam is more beautiful and fine.
