Abstract (en)
The invention provides, for silencing the blowing of galvanized pipes, the inventive combination of a mobile element for gradual expansion of the steam with pressurization of the chamber for receiving the partially-expanded steam. In this manner the operating noise level can be reduced from over 130 db to less than 100 db. <IMAGE>
