A. Structure of Square Tube Description: 

    The square tubes are used in structural projects, shelves, racks, trailers and in ornamental purpose. The framework made by square steel tubes, is used for providing support to the roof. This framework is also used as roof top ventilation baffles. With compare to round steel tubes, square steel tubes are little more efficient. The reason is that the square column is more efficient than the solid circular column.

Q:What does the diameter of a steel pipe project mean?
Suppose we specify a standard that defines the nominal diameter of the same steel tube as G-1, then this G-1 is the same as DN50.I hope it doesn't make you any more confused, huh?. If you still don't understand, keep in mind that the nominal diameter is neither outside nor inside diameter.
Q:What is the difference between the stainless steel pipe welded pipe and seamless pipe?

Q:Stainless steel tube, also known as why tube?
Production methods can be divided into two categories: seamless pipe and welded pipeSeamless steel pipe can be divided into hot-rolled pipe, cold rolled tube, cold drawn tube and extruded tubeWelded pipe is divided into straight welded pipe and spiral welded pipe and so on
Q:What is lined pipe?
There are inner pipe jacket, such as day, tube, etc.; there are outside the pipe painted, such as large-diameter water pipes. An internally coated steel pipe for corrosive medium fluids replaces the expensive stainless steel pipe.
