Spiral welded pipe in the Indonesian market so-called spiral pipe, there is also a call pipe casing. Despite its name, it does not mean this pipe-shaped spiral, but rather refers to the raw materials of manufacture which is a strip steel plate that is formed into a spiral and then spliced to form a pipe. In piping systems, pipe types is very restricted for use only for pipes with low pressure for thinness.
Even in the oil and gas industry, the pipeline is not used in pressurized pipe system, mostly used as a casing for the foundation, or as a pipe support. The advantage of this pipeline is very large can be made with ease. But this pipeline has the disadvantage of which thickness to be able to make the spiral is fairly limited, so the pipe is relatively thin. In addition, the number of connections per unit long enough to make an inspection of welding becomes more far-more than the straight welded pipe- when will be used as a pressure pipe.
