SEAMLESS PIPE AND WELDED PIPE FUNCTION

In general, welded pipes are considered to be more vulnerable when compared to seamless pipes because of the weld joints present in the body. Meanwhile, seamless pipes that have no joints or structural defects are felt to be stronger. It is true that theoretically welded pipes have welded joints which make them weaker because they are not resistant to high pressure or high temperature. However, in fact, by going through the proper production process and quality control, welded pipes are clearly more profitable than seamless pipes because the production is simpler and cheaper.

Although the seamless pipe proved to be more resistant to pressure, many protests were raised because of its inconsistent size. The seamless pipe rolling and rolling process tends to produce inconsistent wall thickness when compared to the wall thickness obtained from the welded process made of steel plate or strip. In addition, the complexity of the seamless pipe manufacturing process has made the price soar.

These two pipes have their respective functions and uses. For example, a seamless pipe, this pipe is very advantageous for high pressure and high temperature applications such as in the oil and gas industry, the pharmaceutical industry, and power generation. Meanwhile, welded pipes can be used in all industries as long as temperature, pressure, and other variables are measured and do not exceed the standards set by the manufacturer. Whereas in structural applications, both welded and seamless pipes work equally well.
