ALFA joints 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 II generation joints are universal, i.e. connects flange with any pipe of the same nominal diameter, with all the main features and advantages of the ALFA I generation joints.
Some of the basic advantages of using ALFA joints are:
- very simple and easy installation and deinstallation, with possibility of deep pipe insert, which enables secure connection;
- specially constructed massive gaskets which enable reliable sealing and absorb possible angular deviations of the pipe at the connection point;
- possibility of tightening the gasket in case that for any reason there is a leakage at the joint.
ALFA I generation joints 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.
As time-tested solution, ALFA I joints are still being produced in the range of DN350 upwards, especially since with the increase in nominal pipe diameter there is less importance in universality of the joint.
Second generation ALFA joints (ALFA II) are made mutually identical for all types of material and pipes which are covered by first generation joints. There is a difference in ALFA-PE II generation 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 pipe diameters which are covered by the single joint, i.e. they are completely universal and cover all pipe types of the same nominal diameter, even the non-calibrated diameter of asbestos-cement pipes, type D, which is a rarety.
ALFA II generation joints are part of ARMAS SYSTEM
