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.
