Low Thermal Conductivity Foam Glass Pipe Elbow For High Temperature Lines

Low Thermal Conductivity Non-Combustible Foam Glass Pipe Elbow

This low thermal conductivity foam glass pipe elbow is a pre-formed 90 degree section that insulates pipe bends and changes of direction in thermal systems. The closed-cell cellular glass structure limits both conduction and convection, so the elbow keeps a low, stable conductivity of roughly 0.040 to 0.058 W/(m·K) and does not lose performance when the surrounding pipe is exposed to moisture or repeated thermal cycling.

Because the elbow is made from inorganic cellular glass, it is non-combustible to A1 class and will not feed a fire or release the dense smoke associated with foam plastics. It matches the straight pipe sections to give a continuous, uninterrupted insulation layer right through the bends, which removes the cold spots and condensation that appear when bends are left uninsulated or poorly covered.

Technical Specifications

Key Advantages

• Pre-formed 90 degree elbow to match straight pipe sections
• Low conductivity of 0.040 to 0.058 W/(m·K) at 25 °C
• A1 non-combustible inorganic cellular glass
• Continuous insulation through bends with no cold spots
• Near-zero water absorption and vapour tight
• Rigid, dimensionally stable and easy to fit on site

Typical Applications

• Insulated pipe bends and direction changes
• Chilled water and brine piping
• Steam and hot process piping
• Cryogenic and low-temperature piping
• District heating and cooling networks

Supply and Installation

The sections are supplied as pre-formed pieces in standard pipe sizes and can be cut, fitted and bonded on site with conventional tools. Every batch is produced from recycled glass under a controlled kiln process and inspected against the relevant standards before dispatch. The material is lightweight yet tough, easily handled by a single installer, and it is fully recyclable at the end of its long service life; it is produced without CFC or HCFC blowing agents. If you would like the full technical data sheet, the applicable test report or a project specific quotation, our team will gladly assist and advise on the most suitable size, thickness and grade for your piping system.

Frequently Asked Questions

Q: Why use a pre-formed elbow?

A: A pre-formed elbow gives the same thickness and conductivity as the pipe section through the bend, so there is no gap, no cold spot and no condensation at the direction change.

Q: Is the elbow non-combustible?

A: Yes. It is inorganic cellular glass classified A1 non-combustible, so it does not contribute fuel to a fire.

Q: Which angles are available?

A: The standard piece is a 90 degree elbow; other angles can be produced to order to match the pipe routing.
