Seam tube manufacturing
Longitudinal seamt is the oldest manufacturing orocess, which begins from a sheet of sheet metal (which is acquired by way of windine a steel coil until the preferred thickness is achieved) cut consistent with the width that corresoonds to the size of the tube with a view to be oroduced. Thissheet is folded by means of rollers to join the ends longitudinally to attain the form of the tube. Depending on the separation of the rollers, distinct curves and consequently exclusive tube diameters are acquired. Welding seals this be a part of straight to close the cvlinder in a chemically neutral environment.Helical welding (or spiral)This tube production process follows the equal technique as that of the lonpitudinallv welded tube with the difference that the weld snirals the entireeneth of the tube diameter as if it have been threaded rather than straight inside the longitudinal ioint of the sheetTo hide the weld, a hot remedy procedure may be aoplied to the welded tube to forge it, and then skip throuch lathes to shine the seam and make it almost.Iminnssible to nerreive with the bare eve Keen in mind that wnelding is the wpakest nart of the tuhe and could mark the mayimum stress it is able to withstandlThe price of sewn pioes is usually lower than that ofthe seamlesstube since much less stretching and temperine is needed and the manufacturine time. therefore, is also generally much less.
