The welded tubes from hot rolled coils can be realized
with a diameter up to 323,9 mm and with a thickness
up to 16 mm.
They are produced through the cold forming of a tape
in hot laminated steel with a sequence of rollers that lead
to the finished dimension of the product ready to be weld in H.F.
These pipes are used in different fields: from mechanic
to structure, from exchangers to cold drawing transformation.
