What Korema does

Korema GmbH & Co. KG is a privately held German manufacturer founded in 1968 and headquartered in Weiterstadt near Frankfurt/Main, with a registered general partner entity in St. Gallen, Switzerland. The company specializes in the design, production, and installation of fabric expansion joints (Weichstoffkompensatoren) used in industrial pipe systems to absorb thermal expansion, dampen vibration, and provide acoustic decoupling across plant engineering, power generation, chemical, mechanical engineering, ATEX-classified, and food/pharmaceutical applications. Its workforce is small (11-50 employees) and the firm positions itself as a global market and technology leader in its niche.

The product portfolio comprises five families: Band-type, U-type (flange-type), Sonderformen (custom shapes from CAD drawings), ELTROFLON® (electrically conductive, ATEX-certified for zones 1+2 and 21+22, surface conductivity below 10⁹ Ohm), and SIMIFLON® (FDA/EU-compliant composite for food and pharmaceutical process piping, supplied with traceable ID and FDA certificate per delivery). Core materials are glass-fiber-fabric-reinforced elastomers compounded in-house, with all stages of production (CAD, laser-cutting, assembly) carried out at the Weiterstadt facility to maintain full control of the value chain. Certifications include ISO 9001 and the RAL Gütezeichen quality mark, and the firm holds numerous national and international patents.

Korema operates a B2B direct-sales model: customers request consultation, receive a quote, and receive components custom-manufactured to their drawings with no size limitation and pricing driven by specifications, materials, and required certifications. The company sells globally through its own sales force and a worldwide partner network without resellers or channel intermediaries, and is managed by Managing Director Dipl.-Ing. Walther Merz.

Core offering

Korema designs, produces, and installs custom-made fabric expansion joints (Weichstoffkompensatoren) for industrial pipe systems. Made from glass fiber fabric-reinforced elastomers, the joints dampen vibrations, compensate for thermal expansion and length changes, and provide acoustic decoupling. The portfolio covers U-type, band-type, special-shape, plus proprietary ELTROFLON® (electrically conductive for ATEX zones) and SIMIFLON® (FDA-compliant for food/pharma) variants.

Product overview

KOREMA® is a leading manufacturer of fabric expansion joints (Weichstoffkompensatoren) made from glass fiber fabric-reinforced elastomers. The product portfolio consists of five main types: Band-Typ (belt expansion joints for large-scale plant construction), U-Typ (flange-type expansion joints for gaseous and liquid media), ELTROFLON® (electrically conductive ATEX-certified expansion joints), SIMIFLON® (FDA/EU-compliant expansion joints for food and pharmaceutical applications), and Sonderformen (custom-shaped expansion joints produced to customer specifications). All products provide vibration damping, thermal/acoustic decoupling, and compensation for temperature-induced length changes and wind-load twisting in industrial piping systems.

Direct peers

• BOA Group: German manufacturer specializing in metal and fabric expansion joints for industrial piping. Competes head-to-head with Korema in plant engineering, power, and chemical applications across Europe.
• UNIFLEX: German specialty manufacturer of fabric expansion joints and related compensators. Directly comparable mid-sized competitor serving similar plant engineering and OEM customers in Central Europe.
• Metraflex: US-based manufacturer of expansion joints and flexible pipe connectors. Comparable product range with overlap in industrial piping, HVAC, and power applications where Korema's band-type and U-type joints compete.
• Senior plc (Flexonics division): UK-listed industrial group with a Flexonics division producing fabric and metal expansion joints and flexible piping solutions. Overlaps directly with Korema's product offering in industrial and process industries.
• Mercer Rubber: US manufacturer of flexible piping products including fabric expansion joints for industrial applications. Overlaps with Korema's product category across HVAC, power, and process industries.
• Garlock (Inpro/Seal): US-based manufacturer of industrial sealing products including fabric and elastomeric expansion joints. Competes with Korema in chemical, power, and general industrial piping applications, especially in the Americas.
• Witzenmann: German-headquartered global leader in metallic and fabric expansion joints with a comparable product portfolio across industrial piping applications. Witzenmann is Korema's most direct and largest competitor in the fabric compensator segment.

Broad incumbents

• Trelleborg AB: Global Swedish industrial polymer group with an antivibration and sealing division that supplies expansion joint and damping solutions. A larger diversified player whose offering intersects with Korema's fabric compensator business.
• ContiTech (Continental): Industrial rubber products arm of Continental AG, offering fabric expansion joints as part of a much broader industrial portfolio. A scaled incumbent with overlapping capability but a wider product scope than Korema's focused offering.

Regional players

• Pacific Hoseflex: Australia-based manufacturer of expansion joints and flexible hose assemblies for industrial applications. Operates in a similar product category but primarily serves the Asia-Pacific region rather than competing head-to-head in Korema's core European market.
