NHFLEX-D
High-temperature rubber expansion joints are specialized solutions designed to endure extreme thermal environments exceeding 150°C. Utilizing advanced elastomers like peroxide-cured silicone and FKM (Viton®), these joints maintain structural integrity and sealing efficiency in applications such as exhaust systems, industrial furnaces, and high-pressure steam lines. The proprietary multi-ply construction incorporates aramid fiber reinforcement and high-temperature adhesives, enabling continuous operation at 200°C (silicone) or 230°C (FKM) without delamination. Certified to ASME B31.3 process piping standards, they are indispensable in industries requiring resistance to thermal fatigue and aggressive media.
1. Exceptional Heat Resistance: Silicone models withstand intermittent peaks up to 250°C, while FKM joints resist thermal degradation from hot oils and hydrocarbons.
2. Multi-Axial Compensation: Accommodates combined thermal growth and mechanical vibration in three planes.
3. Flange Options: ANSI Class 150/300 flanges in 304/316 stainless steel or carbon steel with high-temperature coatings.
4. Vacuum Stability: Internal stainless steel anti-collapse rings prevent buckling under negative pressure conditions.
5. Fire Safety Compliance: FM Approved and IMO-certified designs available for hazardous areas.
· Energy Sector: Manages steam turbine exhaust expansion in combined-cycle power plants.
· Petrochemical Industry: Connects catalytic cracking units and flare gas recovery systems.
· Aerospace Testing Facilities: Absorbs thermal shocks in jet engine test rig exhaust ducts.
· Glass Manufacturing: Compensates for thermal movement in furnace feed systems and annealing lehrs.
Q: Can these joints withstand rapid thermal cycling?
A: Yes, our silicone-FKM hybrid designs are optimized for >500 cycles between 50°C and 200°C.
Q: What is the shelf life of unused joints?
A: Properly stored in original packaging, they retain performance characteristics for 8 years.
Q: Are custom profiles available for tight spaces?
A: Compact “pancake” or rectangular profiles can be engineered to fit spatial constraints.
