~Our products--- spiral seam welded perforated tubes 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.
