Expansion - Import export

Expansion joints serve a crucial role in industrial ductwork by facilitating the controlled expansion and contraction of ducts. Their primary function is to accommodate thermal movements within the ductwork system. They mitigate thermally induced stresses by allowing thermal movements in a relatively unrestricted manner. Expansion joints contribute to the overall flexibility and structural integrity of the system which is essential in preventing the build-up of stress that could otherwise lead to damage in equipment, ductwork, and supporting structures.

LIPP® Tank Refurbishing Quantities change and existing tanks become too small – these are also problems that frequently arise. In such cases, the mobile machine technology from Lipp using the LIPP® DoubleSeam System or the LIPP® welding technique offers a solution that is as simple as it is costeffective, while being extraordinarily stable. Tanks can be installed on site in any size required and can be placed in an existing steel or reinforced concrete basin using a mobile crane. The existing tank volume is utilised, eliminating the need for expensive demolition work. There is also a range of materials to choose from for the tank itself so that it can be optimally matched to the intended application. VERINOX®, the combination material developed by LIPP® consisting of galvanised steel (for the outside of steel containers) and stainless steel (for the inside of containers), is characterised in particular by the excellent costbenefit ratio that it offers.

Penstocks are used to discharge the headwater from a reservoir. Due to thermal and dynamic effects on the pipelines which are usually run underground in the mountain, compensation for expansion is necessary. By fitting an expansion joint, slow creep movements, eccentricity, dilation and also pipe misalignment can be reliably absorbed. The MANOY® system seal WP, type 436, was specially developed for leakagefree operation of an expansion joint.

Dampers play a crucial role in the functionality of industrial ductwork as they are designed to control the flow of air or flue-gas within the ducts. The primary purpose of most dampers is to act as shut-off dampers. This means they are either fully open or fully closed depending on the operational requirements. However, some dampers are specifically installed to modulate the gas flow, allowing them to function in various partially open positions. The variability in damper functionality caters to different operating scenarios and provides flexibility in managing the flow of air or flue-gas through the duct system.

Cellular rubber made by KOPP is the ideal material for sealing, insulating, insulating, dampening and as rattle protection. Cellular rubber is a porous, closed-cell rubber quality that is available in various strengths and densities. It is manufactured using the so-called expansion process - based on natural and/or synthetic rubbers, such as EPDM and other synthetic elastomers. Cellular rubber is airtight and waterproof and therefore (unlike foam rubber) does not require an outer skin to be used as a seal. From our KOEPPcell® range you can get the following cellular rubber or elastomer types in our usual high quality at extremely interesting prices: • Natural rubber (NR-L, NR-S) • EPDM (EPDM-L*, EPDM-S*, EPDM- SUW*, EPDM-W*) * all also peroxidically cross-linked • Chloroprene rubber (CR-L, CR-S) • EPDM-PE blend • EPDM-CR blend (EPDM-CR-L, EPDM-CR-S ) • mixed-cell (semi-closed) EPDM (EPDM-SC) Technical properties Can withstand a wide range of requirements

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

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...

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.

Axial expansion joints compensate assembly tolerances and thermal longitudinal expansion in the direction of the tube axis. Depending on the design, they can be impinged with pressure internally and externally. Using a guide sleeve 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.

Like oxides and nitrides, Silicon Carbide (SiC) is a very hard-wearing material, again requiring diamond-grinding methods to process once fired. Although not exclusively, carbides are used mainly for applications in which physical wear is a major consideration. They are amongst the hardest materials available.
