Cost efficiency is one of the pillars of any industry. While most stainless steel and alloy steel grades are expensive, the use of a Carbon Steel Spiral Welded Pipe considerably lowers the cost of the entire operation. This is because the breakdown of producing a carbon steel pipe yields lower cost. For instance, the cost for a simple carbon steel pipe is lower than alloy steel because the elements used to alloy the Carbon Steel EFW Pipe are only two, i.e. carbon and iron. Though, some of these alloys may include trace quantities of manganese, copper, and silicon. All of these may either be in the form of impurities or they may be added to the melt of the CS ERW Pipe by the manufacturer. An inexpensive method of constructing pipes includes using welded pipes. Manufacturers use a carbon steel sheet, with the width of the sheet matching the circumference of the Spiral Welded Steel Pipe.
The sheets are held together with a simple weld seam, thus ensuring a more permanent joint. In contrast to seamless pipes, which use billets for extrusion, the manufacture of a Carbon Steel Welded Pipe is simpler as well. Hence, the method of construction, and the chemical composition of the pipe, bring down the cost of using a carbon steel pipe in any application. Since the pipe has relatively no alloying content, the pipe won’t be able to demonstrate properties as good as low alloy steels. However, it does offer certain other advantages, including durability, shock resistance, and moderate to high strength, which of course depends on the grade of the Carbon Steel ERW Pipe.
