Expansion joints - Import export

Certain specialised areas of various industries require at times applications which cannot be adequately realised by the use of standard components. Specially designed expansion joints are used in these cases. The following specific design types are offered in addition to the standard series: pressure balanced expansion joints for axial and lateral movement elbow-conected pressure balanced expansion joints chamber expansion joints expansion joints, pressure applied externally expansion joints with PTFE single used expansion joints expansion joints for food industrie chamber expansion joints DN50 / DN150 / DN200 DP inside 6 bar DP outside 4,5 bar DT 155° C ax. mov. +/-15 mm lat. mov. +/-10 mm

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

Universal expansion joints absorb axial, lateral and angular movement simultaneously. Installation is primarily in the low pressure area. Using a guide tube protects the metal bellows from abrasive media or flow-induced oscillations. The reaction forces caused by the internal pressure must be absorbed by sufficiently dimensioned anchor points.

The term metal bellows refers to a structure that is composed of one or more stainless steel sleeves fitted into one another and is rendered elastic by the introduction of parallel corrugations. Metal bellows can be arranged to complete combinations of metal bellows (expansion joints). Thus, every specific requirement can be met. As raw material for the sleeve production, stainless steel strips or sheets with a thickness of 0.15 - 3 mm in the standard grades are used: 1.4541 / AISI 321 1.4571 / AISI 316Ti 1.4404 / AISI 316L 1.4307 / AISI 304L                                                              material with high chemical resistance and temperature resistance:   1.4435 / AISI 316L 1.4539 / AL 904L 1.4878 / AISI 321H 1.4828 / AISI 309 1.4462 / AISI 318 LN 1.4410 / AISI F53 or additional special materials:      1.4876 / Incoloy 800HT 2.4858 / Incoloy 825 2.4856 / Inconel 625 2.4816 / Inconel 600 2.4610 / Hastelloy C-4 2.4819 / Hastelloy C-276 2.4602 / Hastelloy C-22 3.7035 / Tit
