Our products**- spiral seam welded perforated tubes and shroud of sand control screen can be used for filtration and separation fields.

Although Spiral Weld is a more challenging process compared to longitudinal welded, the following advantages are exhibited:

●More Flexibility over a wide range of sizes, thus able to produce at unconventional diameters and tolerances.

●An increased safety factor due to the internal stress on the Spiral Weld being less than on a longitudinal weld

●The use of strip instead of plate permits more uniform wall thickness due to the close dimensional tolerance

●Due to the continuous process, any length of tube can be produced as opposed to the length limitation of a plate mill.

●The tube is straighter and rounder than one produced on a longitudinal mill.

●Spiral Weld provides greater strength and rigidity at reduced wall thicknesses.
