Q:What's the difference between a rectangular tube and a rectangular steel tube?
No difference, but your name is different, rectangular steel pipe, but can be divided into seamless rectangular steel pipe and welded rectangular, these two, in the material will also have a difference, I do not know how to help you
Q:What's the difference between steel pipe and pipe fittings?
Pipe classification: steel pipe seamless steel pipe and welded steel pipe (tube) two categories. It can be divided into round tube and special-shaped tube according to the sectional shape. The round steel tube is widely used, but there are some special-shaped steel tubes such as square, rectangle, semicircle, hexagon, equilateral triangle and octagon.
Q:Is steel pipe made of profiles?
Large steel: large steel, I-beam, channel steel, angle steel and flat steel are hot rolled, round bar, Fang Gang, six angle iron in addition to hot rolling, there are forging, cold drawn and so on.
Q:How to distinguish seamless pipe and welded pipe?
If there is a weld seam in the fracture surface, whether it is inside or outside the pipe, then it is the welded pipe
Q:How can galvanized steel tubes be painted on the surface?
Galvanized parts are nonferrous metals, ferrous metals are black, all metal adhesion is poor;
Q:What's wrong with the 3PP anticorrosive steel tube?
PP and PE are similar in processability, and the 3PE coating can be used to produce 3PP coatings without the need for a special 3PP coating line. However, the difference between PP and PE materials makes the 3PP and 3PE coatings show different properties, which can be applied to different environments. The advantages of 3PP coating on some properties make it possible to play an important role in the field of 3PE coating. Therefore, many foreign pipeline projects use 3PP anticorrosive coating.
Q:DN80 seamless steel tube, what is the standard thickness?
Commonly used DN80 seamless steel pipe caliber should be 89mm*4mm.
Q:How much is 4 inches steel tube MM?
1 inches =25.4 mm;4 inches =101.6 mm;The specification of steel pipe is usually nominal size;
Q:Can galvanized steel tubes simmer?
Galvanized pipe bending is one of the elbow, the surface of the pipe is coated with a layer of zinc material to improve the corrosion resistance of the elbow. Galvanized pipe bending hot galvanized and galvanized two kinds, hot galvanized, zinc coating thickness, zinc plating cost is low, the surface is not very smooth. Galvanized pipe bending cold tube, hot tube, the former has been banned, and the latter is also advocated by the state for the time being.
Q:Is the electric pipe used with steel pipe or PVC pipe?
Electric pipe laying is generally divided into the following circumstances:1) the explosion-proof area must be galvanized steel pipe and explosion proof flexible pipe (used for front end equipment connection);2) non explosion-proof area can use KBG pipe or PVC tube, the former is higher cost, but the installation is firm, the latter is low cost, easy to construction, and in the rain where it will not rust, but compared to the KBG pipe may be damaged.
