STOP/SYSTEM® H1 PE 63÷125 - STEEL 2"÷4"
The evolution of the STOP/SYSTEM® concept has today led to the introduction of hybrid equipment mod. H1–H2–H3-H4-H5, capable of operating indifferently on steel, cast iron and polyethylene pipelines.
The modularity and compatibility of the system components with the various pipe materials allows a significant reduction in the investments required in equipment, consumables and operator training.
Safety, lightness and ease in both use and maintenance have always decreed the international success of STOP/SYSTEM® equipment in the gas, water and oil industries.
The new STOP/SYSTEM® equipment mod. H1-H2-H3-H4-H5 allows line stop operations on steel, cast iron and polyethylene pipes with 12 bar maximum pressure (mod. H1-H2-H4-H5) and 8 bar (mod. H3).
They are the result of fifty years of Ravetti® experience in the construction of flow stop equipment and set a new reference standard in terms of safety and versatility.
The construction involves the massive use of aluminum alloys, in order to make handling as easy as possible.
Among the most significant innovations, it is worth mentioning the system present on the pipe drilling machines which avoids perforating the polyethylene pipes from side to side, the housing bells with viewer with increased visibility and equipped with a knob for compressing the sealing gasket on the rod, the innovative construction of the nozzle for the by-pass with which the stopper bell of the H3 model is equipped.
