Stainless Steel Rectangular Hollow Section (RHS)
Alloy grade 304 stainless steel square pipe is formed from coils after which it is then run through a series of dies. These squared SS 304 sections are welded from inside the pipe in order to form their shape. Generally, a SS 304 box pipe is used for maintenance as well as for structural purposes. Some examples of applications for the Stainless Steel Square Pipe would include railings, building construction, and sign posts.
The ASTM A554 specified grade 304 Stainless Steel box pipe is usually measured by their outside dimensions along with their wall thickness as well. According to specification ASTM A554, the standard covers piping in various shapes such as the Stainless Steel Square Pipe, which are typically meant in those mechanical applications where mechanical properties, appearance, or resistance to corrosion are considered to be the primary requirement of that particular application. This guide covers standard specification for welded ss 304 square hollow section furnished in shapes like round, rectangular, or any special manufactured pipes.
Several industries value SS 304 hollow section for both its tensile strength and its ability to withstand extreme temperature, pressure as well as destructive elements. Additionally Food Grade Stainless Steel Square Pipe undergoes less processing in comparison to that of other kinds of mechanical tubing. Hence, the low cost of these squared pipes can prove to be a cost effective solution for less demanding applications, especially in the food industry. The specified ASTM A554 Seamless Square Stainless Steel Pipe produced in our factory has been made from flat-rolled steel with the help of an automatic welding process with no addition of any filler metal used during welding. Additionally, at our factory, we conduct a heat analysis on several grades of steel for e.g. S 304 square pipe, in order to check its conformance to the required chemical composition as mentioned in specification ASTM A554.
