The stainless steel square tube is a kind of hollow steel, because the cross section is square, so it is called square tube. A large amount of pipelines for transporting fluids, such as oil, sky gas, water, gas, steam, etc. In addition, when the bending and twist resistance strength is the same, the weight is mild, so it is also widely used in manufacturing mechanical parts and engineering structures.
What is the difference between the craftsmanship of stainless steel tube?
In fact, there are basically no differences, but the gentleman produced a round tube, and then pressed the finished pipe with a mold.
The advantages of stainless steel square pipes are the same as other stainless steel products. They are mainly resistant to ordinary environmental corrosion and beautiful materials. Generally, 304 and 304L materials are relatively cheap. Of course, 316, 316L, 321 and other materials will be used in some special temperature environments. It's relatively slightly more expensive.
The square tube also has several surface processing status such as polishing, pickling, sandblasting and other surface processing status.
In addition, why does the square thickness of uneven wall thickness? This is due to the error of the cymbal tube that can not be the right circle, which means that there is a phenomenon of uneven wall thickness. As long as it is within the tolerance range, this unevenness is allowed.
In the final sales session, the square tube was delivered at the actual weight (that is, the price). Generally, customers need special specifications to buy molds and produce, so additional costs are required to buy molds, so the processing costs must be added.
