Compression sleeves and fittings

the PPSU (polyphenylsulphone) fittings are robust and able to withstand many different loads. The large internal diameter gives the fitting optimum hydraulic properties. The appearance of corrosion, such as occurs with metals, is eliminated. PPSU has no tendency towards encrustation and is completely harmless in terms of hygiene.

Polymer specialist Rehau has launched a new generation of its tried and tested Rautitan installation system. Thanks to numerous innovations, the system will cover not only the application areas of drinking water and heater connection but also gas and sprinkler systems. The Rautitan PX polymer material fittings and compression sleeves, which Rehau has used to optimise the compression sleeve connecting technology, are the core of the new generation. Despite their low weight,

Rautitan PX compression sleeves and S S fittings

models can be put on from both sides. The elasticity of the material means that only low clamping forces are required. The stainless steel (Rautitan SX), brass (Rautitan MX) and red brass (Rautitan RX) fittings are also produced with the polymer compression sleeve for the applications of drinking water and heater connection.

Unlike the classic Rautitan brass compression sleeves, the polymer

Seamless steel pipe fittings and flanges

Unifit Boru Baglanti, Turkey, is a manufacturer and wholesaler of seamless steel pipe fittings and flanges. Sister company Burak Boru, a seamless carbon steel stockist, supplies all of Unifit’s product ranges.

In the hardness test: Rautitan PX S S compression sleeve stretch test

Rautitan PX compression sleeves are made of PVDF (polyvinylidene fluoride) and the fittings of PPSU. The qualities of both high performance plastics have been proved, for example, in aircraft construction and in clean room production. The materials stand out for their notched impact strengths, chemical and heat aging resistance. Rautitan PX elements are particularly light and can be processed safely even at extreme temperatures down to -10°C. Rautitan PX compression sleeve hard- ness tests have proved the loading capacityof thepolymer systemelements. At the lower processing temperature of -10°C, the compression sleeve is expanded. In this, the material absorbs a stretch that is in excess of the forces actually in effect from the compression.
