PP Reducing Coupling /PP Compression Fittings

PP Reducing Coupling /PP Compression Fittings

FIELDS OF APPLICATION

PP compression fittings and clamp saddles are designed specifically for cinnecting polyethylene pipes with an outside diameter of 16-110mm (135mm for clamp saddles). They are fully compatible with all PELD,PEHD,PE40,PE80 and PE100 pipes complying with EN12201,ISO4427,ISO14236,ISO13460,DIN8074. They are normally used to convey drinking water and fluids at pressure up to 16 bar for generic applications.The quality of the material used makes these fittings resistant to etching by numerous chemical substances and to UV-rays. The PP universal fitting can b e used to connect systems using PE metric piping with existing pipes made of any material,with external diameters of 15-34mm.

OPERATING TEMPERATURES

PP Fittings and clamp saddles are not suitable for use with hot water for the limits dictated by the use of polyethylene pipes.

Maximum operating temperatures refer to the use of polyethylene pipes; it is therfore necessary to refer to the regulations applicable in the country of use. The fittings and clamp saddles can with stand temperatures below 0ºC. The table below shows the maximum operating pressure during continuous operation (PFA) with changes in temperature if the liquid converyed is water,in compliance with EN 805,EN 12201 and ISO 13761. For values falling within the set range,alinear interpolation can be obtained.

TESSILE STRENGTH

All fittings under go tensile strength tests with the loads shown in the table blow,in compliance with the strictest standards and regulations.
