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:Seamed steel pipe seamless steel pipe, carbon steel pipe, galvanized pipe, four how to distinguish between
Welded and seamless steel pipe is divided according to the processing form, usually welded seam steel tube, seamless steel tube drawing and hot two ways, carbon steel is material, galvanized pipe is welded pipe production after the surface is galvanized
Q:What is lined pipe?
Pipe lining is a new technology in recent ten years of development, also called composite pipe conveying fluid with different needs, the use of different materials to make the durability of the pipeline inner wall and outer wall of pipeline, to ensure the purity of the fluid, pipeline adaptability, performance is greatly improved, more extensive use.
Q:What connections are there for concrete filled steel tubular column foundations?
Strengthening ring joint is a more common in the construction of steel pipe concrete column construction, it is to beam column connection through the upper and lower plate reinforcing ring bending force transmission way is through two to strengthen the uniform arrangement between the rings radial ribs and rib structure to connect with the ring the pipe wall at the top of the plate, so as to transfer the shear stress, so as to strengthen the thickness and improve the quality of connection engineering advantage. In the process of engineering construction, according to the construction principle of longitudinal reinforcement of Deng Qiang to control, so that the smaller width of not less than the replacement of the width of the connecting plate 70%, also need to be given due attention in the form of node selection
Q:Why seamless steel pipe called seamless steel pipe?
Seamless is relative to welded steel pipe, because welded steel pipe is welded with steel strip, seamless steel pipe is made of whole round steel empty, no welding seam.
Q:Where is the difference between seamless steel pipe and welded pipe?
Seamless steel tube is formed during rolling. Welded steel pipes need to be welded after coiling, and spiral welding and direct welding are generally used. Seamless performance is better, of course, the price is higher.
Q:What's the material of Q325 steel pipe?
Plain carbon structural steelIt's a kind of steel material. Q stands for the yield of this material, and the latter 325 means the yield value of this material, at around 325. And the yield value will decrease as the thickness of the material increases.
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:304 stainless steel tube with the diameter of 25*2-3 is what mean
This is according to the "water drawing standards" (GBT50106-2001) in 2.4.2-2 seamless steel pipe, welded steel pipe (straight or spiral seam), brass, stainless steel pipe, pipe diameter should be D diameter * thickness representation (such as D108 * 4 and D159 * 4.5); and the provisions of the habit of acting D with seamless pipe diameter.
Q:Galvanized steel pipe DN100 and SC100
DN is the meaning of "bore", also expressed in water supply and drainageSC is welded steel pipe, generally GB tube, that is, thick walled steel pipe, look at the design requirementsMT refers to the wire tube, usually thin-walled tube, there are KBG and JDG
