Metal expansion joints - Import export

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.

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.

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.

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
