Beldam Crossley engineers advanced industrial braid materials for sealing solutions that operate in some of the most demanding environments on earth. From aerospace engines and gas turbines to marine tanker hatches and industrial packing systems, our woven products are built on carefully selected fibres and metallic braids that deliver strength, resilience and long-term sealing integrity.
Across product lines including Lidpack®, Cordseal® and Pilot® packing and overbraid, material selection is critical. Each braid, core and reinforcement is chosen to withstand extreme temperatures, pressure cycling, vibration and chemical exposure—ensuring reliable sealing performance where failure is not an option.
Industrial braid materials are engineered fibre and metallic constructions woven into ropes, packings and seals. Unlike conventional sealing materials, they are designed to maintain integrity under thermal expansion, mechanical movement and fluctuating operating conditions.
In high-performance applications such as turbine sealing, these materials must not only resist heat but also accommodate movement between components, preventing leakage while maintaining structural stability over repeated cycles.
As highlighted in the Pilot Cord Seal data sheet, these seals are specifically developed to reduce hot gas leakage and operate continuously at temperatures up to 1200°C while accommodating expansion between dissimilar materials.
Beldam Crossley combines high-performance fibres with advanced metallic braids to create robust sealing systems.
| Material Type | Material | Key Properties | Used In Products | Typical Applications |
|---|---|---|---|---|
| Core Fibres | Amorphous Silica | Exceptional high-temperature resistance, thermal stability | Cordseal®, Pilot® packing | Aerospace engines, gas turbines, exhaust systems |
| Metallic Braids | Inconel® 600 | High strength, oxidation resistance, extreme temperature capability | Cordseal®, Pilot® overbraid | Turbine sealing, aerospace, high-pressure environments |
| Metallic Braids | Haynes® C214 | Enhanced corrosion and heat resistance | Cordseal®, Pilot® overbraid | High temperature and chemically aggressive environments |
| Glass / High Temp Fibres | Specialist glass-based yarns | Thermal insulation, structural integrity | Packing and overbraid systems | Industrial sealing and thermal barriers |
| Aramid Fibres | High strength synthetic fibres | Mechanical strength, abrasion resistance | Pilot® packing | Dynamic sealing and high-load applications |
| Carbon-based Fibres | Engineered carbon yarns | Thermal stability, low creep | Specialist packing solutions | High temperature sealing |
| PTFE-based Yarns | Lubricated or treated fibres | Low friction, chemical resistance | Packing and sealing systems | Chemical processing, valves, pumps |
| Hybrid Constructions | Multi-material braids | Balanced thermal, mechanical and chemical performance | Across all woven product lines | Complex, multi-condition environments |
The combination of these materials allows Beldam Crossley to engineer sealing solutions that maintain performance across wide operating ranges rather than relying on a single material approach.
Cordseal® products are constructed using high-temperature core fibres such as amorphous silica, protected by metallic outer braids including Inconel® and Haynes® alloys. This combination enables operation in extreme thermal environments, including aerospace and gas turbine systems.
These seals are designed to accommodate thermal expansion, resist vibration and maintain sealing integrity across repeated cycles. Their braided construction allows flexibility while maintaining strength, making them suitable for both static and dynamic sealing interfaces.
Lidpack® products are engineered for marine tanker applications, where exposure to fuels, chemicals and environmental conditions is constant. The braid materials used prioritise durability, chemical resistance and long-term sealing performance.
The woven construction ensures consistent compression and recovery, allowing hatch seals to maintain integrity during loading, transport and discharge cycles. Material selection also considers resistance to hydrocarbons and aggressive cargoes, ensuring compliance and safety in marine environments.
Pilot® packing solutions utilise a combination of high-performance fibres and engineered braid structures to deliver reliable sealing in pumps, valves and rotating equipment.
Overbraid systems provide reinforcement and protection, enhancing resistance to abrasion, extrusion and mechanical wear. Material combinations are selected based on duty—whether prioritising strength, flexibility, thermal resistance or chemical compatibility.
The performance of a woven sealing product is defined by its materials. By selecting and combining advanced fibres and metallic braids, Beldam Crossley delivers:
These benefits are particularly critical in safety-led industries such as aerospace, marine transport and energy, where sealing failure can have significant operational and environmental consequences.
Beldam Crossley industrial braid materials are used wherever sealing performance must be maintained under demanding conditions.
In aerospace and power generation, they support turbine efficiency by reducing hot gas leakage and maintaining sealing integrity at elevated temperatures. In marine environments, they ensure secure containment of fuels and chemicals within tanker hatch systems.
Across industrial processing and heavy engineering, braided packing materials provide reliable sealing in pumps, valves and rotating equipment, where wear, pressure and chemical exposure are constant challenges.
No single material delivers optimal performance across all conditions. The strength of Beldam Crossley’s approach lies in combining materials—pairing high-temperature fibres with metallic braids, or integrating lubricating elements into structural yarns.
This ensures each product is engineered for its specific environment, balancing flexibility, strength, thermal resistance and durability.
With decades of expertise in woven sealing technologies, Beldam Crossley has developed a deep understanding of how industrial braid materials perform in real-world applications. Our products are trusted in environments where temperature, pressure and safety requirements push materials to their limits.
Manufactured in the UK and supported by recognised quality standards, our woven solutions are designed not just to meet specification, but to perform consistently over time.
If you are specifying sealing solutions using industrial braid materials, our team can support with material selection, product design and application guidance. Share your requirements and we will provide a technically informed recommendation aligned to your operating conditions.
