Flexible joints for gas GMM GFL STFB
Metal antivibration joints suitable for the installation of blown air gas burners are widely used to eliminate the transmission of vibrations, to facilitate and compensate for the installation of pipes that are not perfectly aligned. The core of the vibration-damping joint is the metal bellows made without helical winding, but with parallel corrugations on a stainless steel tube. Antivibration joints can receive axial [h], angular [∂] and lateral [e] movements and above all vibrations. As a matter of principle, the joints should not be subjected to torsional loads in order not to damage the bellows. GMM vibration damping couplings with male-male threaded connections and GFL and St.FB couplings with flanged connections have a bellows made of AISI 321 stainless steel. The carbon steel flanges are sliding, which allows the holes in the flanges to be aligned with those in the counterflanges, thus avoiding damaging tensions and greatly facilitating their assembly.

AF and GIF metal flexible hoses
The flexible metal hoses of the AF and GIF series are manufactured in accordance with DIN 3384 and are particularly used in industrial combustion plants to supply burners with natural gas or other combustible gases of the first, second and third family and air. Flexibility and strength are guaranteed and optimised by the specially designed corrugation of the tubes. Their remarkably robust, all-metal construction makes them particularly suitable for use in harsh industrial environments, both in terms of temperature and extreme operating pressures.
