METHOD OF CONNECTING CONNECTING ELEMENTS WITH PP-R POLYPROPYLENE PIPE

摘要

The method of connecting the connecting elements with a polypropylene pipe (5) (PP-R) containing an intermediate layer (2) of aluminum foil, implying working steps: cutting the pipe (5) perpendicular to its axis, placing the die (12) and the die of the connecting part in the welding machine and waiting for the welding machine to heat up to 260 ° C, which is different in that it involves working steps: marking the length of the welding; and after heating the welding machine to 260 ° C, push the polypropylene tube (5) (PP-R) over the marked length of the weld containing the intermediate foil layer (2) into the die (12) at the same time and with the same force as connecting piece, which is slowly pushed into the die connecting piece to a certain mark; melting the outer layer of PP-R (3) by contacting it with the melting surface (9) of the outer layer with a rounded end that guides the said outer layer (3); when PP-R heats up the pipe (5), which is pushed into the plate (12), melts the inner layer (1) of the PP-R by contacting it with the melting surface (10) of the inner layer with a rounded end, which directs said inner layer (1) ; when PP-R heats up the pipe (5), which is pushed into the plate (12) when the pipe (5) approaches the end, the molten parts and materials that make up the molten parts of the outer layer PP-R (3) and the inner layer PP-R ( 1) flow into the guide cavity (7) in the die (12) through the PP-R frontal section of the pipe (5), closing the specified foil layer (2) by connecting the outer and inner PP-R layer (1, 3) with each other .
