Refractory Lined Expansion joints
A refractory lined expansion joint is a metal bellows assembly lined with high-grade refractory material, designed to protect the joint from direct heat, erosion, and chemical attack in harsh operating environments. This makes them ideal for high-temperature systems such as FCCU units, refineries, power plants, and chemical processing facilities.
trusted refractory brands custom-built to your needs LSI-MECH manufactures refractory lined bellows that meet stringent technical standards and client specifications, incorporating premium refractory materials.
We offer several application methods for installing refractory and insulation linings, including:
• Casting
• Gunning (pneumatic application)
• Hand-placing
• Pneumatic ramming
All linings are installed in strict accordance with project requirements and industry best practices.
Anchoring Systems & Durability
To ensure maximum service life and structural integrity, we design and install high-quality anchoring systems such as hex-mesh. These systems keep the refractory lining stable under intense thermal cycling and mechanical stress.
