Production of industrial pipes To produce industrial pipes, first a cutting is done and the sheet strip is prepared as much as the pipe environment. The sheet is then turned into a tube and the pipe seam welded. The next step is to remove the welding surface and divide the steel pipe into equal branches. There is also the lateral straightening and framing of the pipe, and the final stage is the inspection and quality control of the product in question.

Estimation and calculation of industrial pipe purchases

Price fluctuations for industrial pipe diameter greater than one inch are reported and calculated as n = 1.5 in most references. According to news sources, the price of black steel was 4 rials a year in the domestic market, and because of the price of black steel pipe diameter, a linear relationship can be predicted for the purchase price of the pipe. There is also a relationship to the costs of operating operations including pipe preparation and welding that should be considered. In addition to the cost of operating and the price of the steel pipe, the cost of transporting the goods to the desired location and testing for the pipeline are also effective factors in calculating the price of the pipe.
