Heat Resistance Buckle Insulation Sleeve

No.LL-HRS-01

Heat Resistance Buckle Insulation Sleeve facilitates the wrapping of large objects. It is made by cutting cylindrical tubes and then stitching them. It has a key advantage: no need to disassemble equipment or cables when installing the protective sleeve. It allows for easy opening and inspection later, meeting the maintenance needs of various on-site equipment. Another benefit is that it can be installed on-site at the factory to ensure proper tightness and structural integrity.

Description

Specification
width: 15MM ~ 130MM
Length: 10-25M per roll
Note: Other inner diameters and lengths are customizable.

Core Features
· Innovative Buckle Design: Featuring a high-performance hook-and-loop (Velcro) design, installation can be completed without disconnecting hoses or cables, significantly reducing downtime during system maintenance.
· Superior Heat Resistance: The outer layer is coated with high-grade silicone rubber, enabling long-term operation at 260℃ and withstanding instantaneous exposure to metal droplets and spatter reaching up to 1650℃.
· High-purity Fiberglass Base: The inner layer is made of high-density alkali-free fiberglass weave, offering excellent thermal insulation and mechanical strength to prevent internal wiring from overheating and deteriorating.
· Multi-layer Protection: It combines flame-retardant (self-extinguishing) properties with moisture resistance, oil resistance, and excellent electrical insulation, making it suitable for extremely harsh industrial environments.

Technical Advantages
1）Retrofit-friendly
For complex pipeline systems already in operation, the snap-fit design eliminates costly dismantling and reconfiguration expenses, making it the preferred solution for equipment upgrades and optimization.
2）OEM/ODM Customization
We offer custom sizing based on different pipe diameters, along with a variety of wall thicknesses and surface finishes, to fully meet your specific industrial standards.
3）Strict Quality Control
Every batch of products undergoes rigorous laboratory testing for fire resistance and physical properties to ensure compliance with international safety standards.
4）Chemical Resistance
It effectively resists corrosion from industrial acids and alkalis, lubricants, and hydraulic fluids, thereby extending the service life of the internal precision hoses.

Common Applications
· Steel & Smelting： Protect electric arc furnace cables and hydraulic systems from damage caused by molten metal splashes and radiant heat.
· Petrochemical & Marine： For fireproofing, thermal insulation, and explosion protection in high-temperature engine rooms and pump room piping.
· Power & EV： For fireproofing, thermal insulation, and explosion protection in high-temperature engine rooms and pump room piping.
· Welding & Heavy Machinery： Protect welding robot cables and hydraulic hoses from damage caused by sparks.
