The inlet and outlet pipes are axial, the body is made of steel with a cylindrical shape closed by conical, flat or pumped bottoms, depending on the application. PROTECTION Silencer treatment by high-temperature finish paint. The silencer is not provided to resist temperatures and pressures due to fuel explosions. ACCESSORIES Silencers can be provided with the following optional accessories: • Flanges and counter flanges. • Set of gaskets and screws. • Supports. • Spark extinction chamber. For special equipment or special situations such as: temperatures above 500 ºC, diameters above 800 mm., Special steels, etc ... please contact us.
