1 EXPANSION JOINT & FLEXIBLE PRODUCT B. TERAL EXPANSION JOINT MEGAFLEXON standard lateral expansion joints are available in two designs. The light design, type MLW, MLF, has tie rods which are secured to the flanges by means of nuts and a specially designed spherical disk, allowing angular movement between bolt and flange. The number of tie rods is dependent on diameter and pressure. MEGAFLEXON standard lateral expansion joint with tie rods is available in a design with single or double tie rods. The design with tie rods can only be used within a limited pressure range and a temperature range(max. Deg. C). The heavy-duty design, type 3, (fig2) has flat iron hinges which are fitted through the flanges and welded onto them on the outside. A hinge, which allows lateral movements, is mounted on the fitting above the center line of the bellows. MEGAFLEXON standard lateral expansion joint with hinges is available as well in a design with a double bellows. Common to both models is the fact that tie rods and hinges alike have the task of absorbing the thrust forces arising from the operating pressure. The tie rods and hinges make axial expansion impossible. This means that a lateral expansion joint can only move sideways(laterally) on one or more planes, making it possible for those movements which are perpendicular to the longitudinal direction to be absorbed. Lateral expansion joints are therefore ideal for installation in pipe systems with bends. a) Advantage -Absorb thermal growth in all direction in one plane -A largely reduced load on fix point b)sadvantage -The changed flow direction 31
