We have decided to produce these sleeves with an innovative patented system of sheet metal moulding, using FE DD13 materials to improve welding, thus distinguishing from the commercially available products
At present we produce:
Variants for pipes ø20 – ø22 – ø24 – ø25 – ø26
Variants for square and rectangular pipes and 10 mm narrow parts.
Example of a pipe with central couplers with a diaphragm provided in the central part between the two sleeves.
