The mechanical reducing socket joins two pipes of different diameter end to end, with no thread and no welding. Both ports are compression ends, but they are not the same size.
In a distribution network the diameter of the line steps down as it moves away from the source. Every step down needs a reducing fitting, and in threaded systems those are the most common places for a leak to appear.
In the TUPYPRES system both ends are made up the same way, simply by tightening the nut, so the reduction is not the weak point of the run.
The TUPYPRES reducing socket is supplied as figure 1932 in the combinations 1 1/2 x 1in, 2 x 1 1/2in and 2 x 1in; confirm current figure- and size-specific approvals before specifying.
The TUPYPRES Reducing Socket is supplied in the 1in to 2in range. To confirm what is in stock in a given size, ask our Dubai office.
An ordinary wrench. No press machine and no special tool is required. Cut the pipe square, deburr it, push it into the fitting up to the marked depth, then tighten the nut by hand and finish with a wrench to the torque and number of turns given in the TUPYPRES catalogue. If a joint is taken apart, replace the ring set before making it up again.
TUPYPRES is a mechanical compression joint. The pipe goes into the fitting and the nut is tightened — no threading, no welding, no flame and no press machine. A ring set already assembled inside the fitting (rubber sealing ring, compression ring and locking ring) makes the joint tight as the nut is drawn up. Installation is far quicker than threading and calls for less skill; the main uses are fire protection, water, gas and compressed air networks.
According to the TUPYPRES catalogue, on steel pipe: water up to 16 bar at 80 °C, liquid fuel up to 16 bar at 80 °C, compressed air up to 10 bar at 80 °C and gas up to 10 bar at 70 °C. Lower figures apply on PE80 and PE100 polyethylene pipe, and the system is not recommended for compressed air on polyethylene.
The TUPYPRES system can be installed on steel pipe to NBR 5580 and NBR 5590 (equivalent to EN 10255 and DIN 2440/2441) and on PE80 and PE100 polyethylene pipe. A transition fitting is also available for joining steel pipe to polyethylene pipe.
Where dimensions permit, genuine TUPY fittings carry cast markings such as the factory mark and nominal size. Check the figure-specific catalogue and packaging as well. The threads are clean and free of burrs, and the galvanised coating is even.
