High Purity EPDM Inner Tube for Thermal and Chemical Resistance
The inner tube is formulated from premium EPDM designed to
withstand prolonged exposure to saturated and superheated steam.
Its enhanced thermal stability prevents microcracking and maintains
elasticity under cyclic heating and cooling. The material also
resists scaling, condensate-induced chemical reactions, and
oxidation, ensuring consistent internal flow and minimal energy
loss over extended service periods.
Triple Layer Braided Steel Reinforcement for Maximum Pressure Endurance
The hose incorporates three layers of high-strength steel braiding,
engineered to evenly distribute internal stress and resist
elongation under pressure. This reinforcement provides superior
burst strength and fatigue resistance, allowing the hose to perform
reliably under continuous high-pressure steam operations. The
triple-braid design also enhances torsional rigidity, preventing
kinking and maintaining hose geometry during installation and
service.
Abrasion and Environmental-Resistant Outer Cover
The outer cover is formulated from a reinforced synthetic rubber
compound resistant to mechanical abrasion, UV radiation, and ozone
exposure. This protective layer safeguards the inner tube and
reinforcement from environmental degradation and mechanical wear.
Its flexible design allows the hose to maintain required bend radii
without compromising structural integrity, ensuring safe handling
and long-term durability.
Enhanced Interlayer Bonding for Delamination Prevention
A proprietary bonding system securely binds the inner tube to
reinforcement layers, preventing delamination under thermal
expansion or cyclic pressure fluctuations. This feature maintains
structural stability at coupling ends, supports secure clamp
engagement, and ensures reliable pressure handling throughout the
hose's service life. Enhanced bonding is critical for preventing
leaks, maintaining safety, and ensuring operational reliability in
demanding industrial environments.
Applications
Pharmaceutical Sterilization Systems
The hose is ideal for delivering high-temperature steam in
sterilization processes, maintaining dimensional stability and
chemical resistance to ensure safe and consistent operation.
Industrial Heat Transfer
Suitable for high-pressure heat transfer lines where temperature
stability and pressure tolerance are critical. The hose provides
efficient steam delivery and minimal thermal degradation over long
service cycles.
Temporary and Flexible Steam Connections
During maintenance, purging, or plant shutdowns, the hose offers
flexible routing while sustaining pressure and thermal performance.
Its durability and flexibility make it suitable for temporary
installations in confined or complex systems.
