EQUIPMENT FOR MANUFACTURING PIPE-COUPLINGS AND PIPE COUPLINGS

摘要

The invention relates to a method and equipment for producing pipe-couplings and a pipe-coupling with improved sealing made this way, with the help of said improved sealing of junctions of plastic pressure pipes (8) and plastic fitting bodies (1) is ensured by a closing flange (4) produced by a manual injection molding machine and where a cohesive bond is formed between the plastic pressure pipe (8) and the plastic fitting body (1) for ensuring closing. The invention relates to a method for a pipe-coupling with improved sealing, when a fitting (1) is housed in an end of a pipe (8) and a unit compiled this way is provided with a leak-proof closing. The method is characterized by that, after joining a pipe (8) and a fitting body (1), a junction formed this way is closed round by a sealing ring (4) made insite by injection molding.
