GROUP FOR DEPOSITING AN EXTRUDED THERMOPLASTIC COATING ON WELDED PIPES

摘要

A group (10) for depositing an extruded thermoplastic coating on welded pipes (20) in rotation and forward movement comprising a main pipe fitting (11) provided with a first end (12) for connecting to an extruder (100) of extruded thermoplastic coating and with a second end (13) associated with an extruder head (15) facing said welded pipes in rotation and forward movement for depositing the extruded thermoplastic coating from said extruder (100) and passing in said main pipe fitting (11), characterised in that it comprises means for cyclic insertion of the extruded thermoplastic coating in said main pipe fitting (11) between said first end (12) for connecting to an extruder (100) and said extruder head (15).
