Superior Thermal Resistance and Stability
The inner tube is crafted from high-purity EPDM, designed to resist
long-term exposure to saturated and superheated steam. Its
molecular structure retains elasticity at temperatures exceeding
180°C, preventing micro-cracking and deformation under pressure.
The material also resists scaling and chemical interaction with
condensates, ensuring smooth flow and minimal maintenance.
Long-term thermal stability reduces downtime and improves
operational reliability, especially in high-cycle environments.
Double Spiral Steel Reinforcement for Maximum Burst Strength
The hose features dual spiral steel reinforcement, providing high
tensile strength and improved resistance to internal pressure
fluctuations. The spiral arrangement distributes stress evenly
along the hose length, reducing fatigue from repeated
pressurization and preventing kinking during installation or
operation. This structure ensures predictable performance under
continuous high-pressure steam applications and minimizes the risk
of sudden rupture.
High Performance Outer Cover
The outer cover is engineered from a heat- and ozone-resistant
synthetic rubber compound that protects the reinforcement layers
from mechanical abrasion, environmental exposure, and ultraviolet
degradation. Its flexible yet tough nature allows the hose to
maintain bend radius requirements without compromising pressure
capacity. The cover also acts as a thermal barrier, reducing heat
transfer to the reinforcement layers and prolonging hose lifespan.
Reinforced Interlayer Bonding
A high-strength bonding compound secures the inner tube to the
reinforcement layers, preventing delamination under thermal
expansion or cyclic pressure loading. This enhanced adhesion
maintains dimensional stability at coupling ends, ensures safe
clamping, and prevents internal separation that could lead to
leaks. The bonding technology enhances both safety and durability,
making the hose suitable for long-term industrial and marine
applications.
Applications
Marine Auxiliary Boiler Systems
Steam hoses with high-pressure and thermal resistance capabilities
are essential for marine boilers, where consistent steam delivery
is critical for power generation and auxiliary systems. These hoses
withstand both high temperatures and the vibration typical in
shipboard environments.
Industrial Sterilization and Heat Treatment
In manufacturing and food processing industries, steam hoses
provide safe, high-temperature steam transfer for sterilization and
heat treatment processes. The hoses maintain stable flow and resist
chemical and thermal degradation during repeated cycles.
Temporary and Flexible Steam Routing
During maintenance, shutdowns, or purging procedures, steam hoses
provide flexible temporary connections. Their resistance to thermal
shock, internal pressure, and abrasion allows safe and reliable use
in dynamic operational scenarios.
