Lateral expansion joints absorb movements vertical to the bracing plane. The reaction forces caused by the internal pressure are absorbed by the joint mounting. Under internal pressure expansion joints generated pressure reaction forces. For a better understanding, the following considerations with different diamaters, pressures and resulting from it the forces: DN 150 -> 25 bar ~ 80 kN = 8 t DN 300 -> 10 bar ~ 100 kN = 10 t DN 1000 -> 1.5 bar ~ 130 kN = 13 t Due to high forces, movements in pipelines of higher nominal size and higher pressure can only be absorbed with braced expansion joints. Applying braced expansion joints pressure stress can be absorbed, while fixed bearings can be dimensioned smaller. In case a 3-hinge-system cannot be applied due to missing space, special-purpose solutions like pressure-balanced expansion joints can be installed. Types of design for lateral expansion joints: ball bearing types with tie rods for all-side movements cross hinged types for...

Angular expansion joints absorb movements perpendicular to the bracing lane. The reaction forces caused by the internal pressure are absorbed by the hinge frame. In pipelines of larger nominal size and high pressure only tensioned angular expansion joints in the form of hinge-systems are able to absorb the expansion. Thus, for pipelines expansion joints are only installed as hinge-systems (combination of either 2 or 3 expansion joints). Those are L-, U- or Z-shaped. This requires additionally a 90 ° redirection of the pipeline. Thereby, stress due to inner pressure will be absorbed by the hinge tensioning. In case those systems cannot be applied due to missing space, special-purpose solutions like pressure-balanced expansion joints can be installed.. Types of design for angular expansion joints: Single hinge angular expansion joint for movements in one plane gimbal hinge angular expansion joint for omnidirectional movement

Flexomat know-how is the customer specific manufacturing of stainless steel corrugated hoses in various formats and dimensions. Flexomat stainless steel corrugated hoses are universally applicable and suitable for various media such as e.g. steam, water, oil, gas or chemical media. Corrugated hoses are applied to absorb movement and vibration or to compensate assembly inaccuracy. type SE: corrugated metal hoses, single-wall, medium wall thickness, standard pitch, one braid Typ SZ: corrugated metal hoses, single-wall, medium wall thickness, standard pitch, double braid Typ SEF: corrugated metal hoses, single-wall, medium wall thickness, low pitch, one braid Diameter DN6 up to DN300 Materials 1.4404 / AISI 316L oder 1.4541 / AISI 321 for the hose and 1.4301 / AISI 304 for the braid delivery length as standard length from stock or customer-specific-length after sprcification all common connectors according customer-specification DIN EN ISO 10380 DIN 3384 (DIN DVGW)

Our highly flexible vacuum hoses are produced from longitudinal seam-welded, thin-walled stainless steel tubes, which are hydraulically formed in special-purpose machines. Our vacuum hoses are specifically cleaned after metal forming, during processing protected from uncleanness and prior to dispatch shrink-wrapped. Furthermore, all vacuum hoses will be leak tested prior to dispatch, by means of helium leak testing with up to 10E-8 mbar*l/s.
