Q:Welded and seamless steel pipe how to distinguish?
Different processing technology:Seamless tubes are made of quality carbon steel or alloy steel. Processing technology of seamless pipe hot rolling and cold drawing is divided into two ways, and the tube is generally based on welded.
Q:How can galvanized steel pipe be connected with stainless steel pipe?
The method of non direct fusion is adopted, such as blue, silk head and movable joint
Q:Seamless steel pipe and welded pipe what is the difference?
The welded pipe is made directly from the stainless steel band by machine, and it is made of round steel or perforated by Guan Pi
Q:ASME seamless tube how to express, what is the form, I did not find on the ASME, thank God!
You can refer to the ASME B31.10, such as the requirements for the SA106GRB seamless steel tube outer diameter of 168.3 x 7.11, specifications can be marked as NPS6 SCH40 SMLS, the real mark should include pressure steel pipe factory name or trademark, and the material level, specifications, standards, wall number, batch number, pressure test (if any), NDE detection (if any)
Q:What is the difference between steel pipe and round steel?
Making ring parts with steel tubes can improve data application rate, simplify manufacturing process, save data and work hours, such as rolling bearings, rings, Jack sleeves, etc., and have been widely used in steel pipe manufacture.
Q:Which is cheaper, angle iron or steel pipe?
Angle iron and steel pipe, angle iron is cheap.
Q:Are galvanized steel tubes the same as degaussing steel tubes?
And the method of magnetic field created by means of electromagnets or permanent magnets. For analysis of residual magnetism, see table (1), select the demagnetizing method and system in combination with the conditions of the construction site (for example, given equipment, etc.). Table 1 magnetic remanence grade and welding conditions
Q:Is there a weld on the outer wall of seamless steel tube?
Seamless steel pipe's inner wall, outer wall, section, cross section can not see the weld seam. Because seamless steel pipe is a molding product, no late roll pressure, welding and other processes. No section, inner wall, outer wall or section, as long as there is weld, it is not seamless steel tube. The inner wall can not see the outer wall of welding seam, but it can be seen that the weld products are fake or polished goods. Some products can not be seen without friction and have weld seams on the outside wall. They are seamless treated steel tubes and are polished goods. The price is much different from the real seamless steel tube. Some bad wounding, confusing concepts, earn illegal profits.
Q:What is the difference between hot dip galvanized steel pipe and galvanized steel pipe?
1, the process is different, one is chemical treatment, one is physical treatment; hot-dip galvanized coating is reliable, not easy to fall off2, hot-dip galvanized coating thickness, so strong corrosion resistance. And zinc plating (electroplating) coating evenly, surface quality is better, coating thickness is generally between a few microns to more than ten microns.3 hot galvanizing is a chemical process, which belongs to electrochemical reaction. Zinc plating is a physical treatment, just brush a layer of zinc on the surface, there is no galvanizing inside, so the zinc layer is easy to fall off. Hot-dip galvanizing is used in building construction.4 、 hot galvanized pipe is to make molten metal and iron matrix reaction and produce alloy layer, so that the substrate and coating two combination.
Q:What materials are used in scaffolding pipes?
The bamboo scaffold board made of bamboo or bamboo.
