Pipe Expansion Joint Insulation Jackets
1. Product Overview
Pipe expansion joint insulation jackets are custom-fabricated removable thermal covers engineered specifically to fit flexible pipe expansion joints, bellows, and thermal compensators in high-temperature piping networks. Because expansion joints must absorb continuous thermal expansion, contraction, and mechanical vibration, traditional rigid stay-in-place insulation cannot be used, often leaving these critical joints uninsulated and causing massive energy waste. Constructed from high-temperature resistant coated fiberglass outer fabrics and filled with flexible, high-efficiency thermal insulation blankets, these removable jackets accommodate movement while eliminating radiant heat loss and protecting system integrity.
2. Core Technical Parameters
-
Outer Fabric: 0.4 mm grey single-sided PTFE-coated fiberglass
-
Insulation Core: Fiberglass wool, thickness to suit the operating temperature
-
Operating Temperature: Designed to the equipment surface temperature; we have built jackets for surfaces up to about 350°C. Please ask us about higher temperatures.
-
Fastening System: Heavy-duty Velcro flaps, retention straps, and flexible bellows-compatible attachment systems
-
Key Characteristics: Accommodates axial/lateral pipe movement and vibration, removable and reusable, rapid installation, excellent thermal efficiency, weather and chemical resistant
3. Common Applications
-
Industrial steam systems, power generation plants, and volatile temperature piping networks featuring expansion joints
-
Chemical processing facilities, oil refineries, and district heating lines requiring flexible thermal insulation
-
Maintenance-heavy piping environments where frequent inspection of pipe expansion compensators and joints is required
