Chemically Resistant High Temperature Inner Tube
The inner tube is formulated from high-grade EPDM, engineered to resist thermal degradation and chemical interaction with condensates or corrosive vapors. Its molecular stability ensures dimensional consistency and prevents micro-cracking or blister formation under sustained high-temperature steam exposure. The tube’s smooth internal surface reduces frictional losses, improving flow efficiency and minimizing energy loss.
Double Braided Stainless Steel Reinforcement
The hose incorporates dual stainless steel braids with optimized braid angles to maximize tensile strength and pressure endurance. This configuration ensures uniform load distribution along the hose, reducing stress concentration points that may lead to fatigue or bursting. The stainless steel reinforcement also improves torsional rigidity, preventing kinking and maintaining operational flexibility in confined or curved piping systems.
Durable Outer Cover for Environmental Protection
The outer cover is a high-strength synthetic rubber compound, resistant to abrasion, UV radiation, and ozone exposure. It protects the reinforcement and inner tube from mechanical damage, environmental degradation, and chemical contamination. The cover’s elasticity allows the hose to maintain bend radius requirements while absorbing minor mechanical shocks without compromising structural integrity.
Enhanced Layer Bonding for Delamination Prevention
A proprietary bonding compound secures the inner tube to reinforcement layers, providing exceptional adhesion and preventing delamination under cyclic thermal or pressure loading. The bonding ensures dimensional stability at coupling points, supports consistent pressure handling, and enhances overall hose durability. This feature is especially critical in chemical or industrial environments with repeated operational cycles.
Applications
