ALFA joints are used as a replacement for certain types of fittings. They are used for connecting the specific pipe with the flange of shutter, fitting, cast iron or steel pipe.
ALFA joints are divided in two generations based on their constructive solution: first (I) and second (II). The main difference between these two generations is that ALFA second generation joints are universal, i.e. connects flange with any pipe of the same nominal diameter, with all the features and advantages of the first generation joints.
Some of the basic advantages of using ALFA joints are:
– very simple and easy installation and deinstallation, in contrast with usual fittings;
– possibility of using the joint as an assembly-disassembly flange during the installation of shutter;
– possibility of tightening the seal in case that for any reason there is a leakage at the joint.
First generation ALFA joints (ALFA I) are made separately for different types of material and pipes, as specified:
AC – for asbestos-cement pipes;
Č – for steel pipes;
LG – for cast iron pipes;
PE – for polyethylene pipes;
PES – for polyester pipes;
PVC – for PVC pipes.
Second generation ALFA joints (ALFA II) are made mutually identical for all types of material and pipes which are covered by ALFA I joints. There is a difference in second generation ALFA-PE joint which has a rubber gasket with toothed ring, which is also the case with the first generation. ALFA II joints have a much wider range of covered pipe diameters which are covered by the single joint.
ALFA II generation joints are part of ARMAS SYSTEM.
