Expansion joints - non-ferrous metal - Import export

Each expansion joint is tailor made. Layers of material are assembled on a frame which conforms exactly to the required profile. Bellows type expansion joints incl. or without reinforcing rings/frames. Diaphragms Expansion joints for varying cross sections and transitions. Construction from round to rectangular Construction according to drawings Non-standard high temperature seals Compound movement

The number of patents awarded to KOREMA® such as SIMIFLON® reflects an ongoing commitment to long term development of specialty materials which have opened new horizons and perspectives for the future. SIMIFLON®, (light colored material) is designated foodstuff quality and certified according to § 177.2600/177.1550 CFR of US Food and Drug Administration (FDA) as well as to EU Regulations EU 2002/72/EG and EU 10/2011.

This is the most installed version of the fabric expansion joints (KOREMA® type A3 or AC3 as well as B3 or BC3). The name »flange-type« is used for expansion joints located between pipe or duct end flanges. For existing plants, the flange design varies according to customers’ requirements or depending on the constructed steel design. For innovative designs KOREMA® will identify the suitable technical and economical solution. Special design: supplied as »open« multilayer expansion joint. On-site service available exclusively from the KOREMA® service team. Insulation is incorporated to protect the expansion joint against abrasion as well as for thermal insulation. The choice of insulating material, either mineral wool or ceramic felt, depends on the design temperature. For operation at or below dew point, a vulcanized elastomeric layer is available. Pre-assembled units, complete with liners and clamp bars, are available.

The belt type is the preferred choice for large diameter ducts. Delivery available with insulation pre-installed for high temperature applications. Insulation depends on temperature level of the medium. Insulation is necessary to protect the expansion joint from abrasive media. Corners of rectangular expansion joint frames should be radiused. Delivered as open-end construction for site completion. The final splice will be made on site. The storage and installation instructions as well as the necessary adhesives are included with each shipment. Pre-assembled endless units are complete with appropriate steel components which may be in several parts depending on the size. KOREMA®’s “on-site service” is available for site supervision.

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.

The Ozdekan EX are waterproof expansion joints that allow absorption of the deck movements. These joints are manufactured with rubber elements and restrained to the structure with proper anchor bolts. The reinforcing metal profiles made of steel are completely inserted and vulcanized to the rubber. This process is a total guarantee against corrosion and allows a longer life to the product. The rubber compound, too, has been intentionally formulated to resist the oil, grease, petrol, salt and sand, without besides, suffering premature ageing phenomena due to sun rays, salt and snow. All the joints follow the deformations and movements of the structure (the movement can exist with every skew angle from 0° to 90°) by shear deformation of the rubber elements. Anchor bolts, made of steel and protected with anticorrosion treatments, absorb the elastic reactions and all the other kind of mechanical solicitations. www.ozdekan.com
