Appls rubber expansion bellows are designed tto take care of reactional forces like thermal expansion, contraction, vibrations, etc, which otherwise break piplines, appls rubber expansion bellows are designed. Appls expertise in designing provides perfect balance between movements [axial, radial, torsional and angular] and pressure bearing capacity. Depending upon application, it is being made up of neoprene, epdm, sililcone viton natural rubber, etc, it is reinforced with specially treated, nylon, rayon, glass, fibre, steel cord, etc. Appls expertise in designing provides perfect balance between movements [axial, radial, torsional and angular] and pressure bearing capacity. Appls rubber expansion bellows are available in sizes which ranges ranging form 1" to 72" nb with hydro testing up to 24-bar pressure. These rubber expansion bellows have either integrated flange [metallic flanges are bonded with rubber] or split back-up flange. These bellows are made as per customer`s design, drawing and specification.
