The original Ravetti fittings are made entirely of ASTM A105 or specific material for low temperatures (down to - 46 °C), and can therefore be used in a wide range of temperatures.
The material used is also characterised by a low carbon-equivalent value, such as to ensure greater ease of welding.
For
easy use, the first part of the internal thread is removed from the
fitting in order to allow an easier engagement of the completion plug
into the fitting.
