## Summary description

Armacell K-36/20 is a polyurethane elbow fitting designed for pipe insulation with dimensions 36/20. The component provides a shaped connection piece for insulating bends in piping systems, matching insulation thickness and maintaining thermal continuity. Suitable for use in HVAC, plumbing and industrial installations where polyurethane insulation is required to reduce heat loss and protect pipework.

## Long description

Armacell elbow K-36/20 polyurethane 36/20 for pipe insulation is a molded elbow fitting designed to provide continuous thermal insulation at pipe bends. Manufactured from closed-cell polyurethane foam, this elbow matches the dimensions 36/20 to fit insulation jackets of corresponding thickness and diameter, ensuring a smooth transition around angled sections of piping. It is suitable for use in HVAC, plumbing and industrial piping systems where maintaining thermal continuity and minimizing heat loss are important.
Advantages
The polyurethane construction offers low thermal conductivity, good mechanical stability and resistance to compression, helping preserve insulation performance at elbows. Its molded shape ensures a precise fit with minimal gaps, reducing thermal bridging at joints. The material is lightweight and easy to handle, and the component is compatible with common installation methods for pipe insulation systems.
Suitable for
Insulating 36/20 pipe bends in HVAC systems
Plumbing installations requiring thermal continuity at elbows
Industrial piping where polyurethane insulation is specified
Applications aiming to reduce energy loss and prevent condensation
Key specifications
Material: closed-cell polyurethane foam
Shape: molded elbow fitting for pipe insulation
Design dimensions: 36/20 profile to match corresponding insulation jackets
Thermal performance: low thermal conductivity characteristic of polyurethane insulation
Physical: lightweight with good compressive strength for handling and installation
How to use
Position the elbow fitting over the pipe bend so that it aligns with adjacent straight insulation sections. Ensure mating surfaces of the elbow and straight insulation are clean and dry before joining. Where necessary, secure seams with appropriate adhesive tapes, contact adhesives or mechanical fasteners recommended for polyurethane insulation to maintain continuity and prevent moisture ingress. Trim edges carefully if slight adjustment is required for a snug fit.
Usage recommendations
For optimal performance, verify compatibility with the existing insulation thickness and use recommended joining materials for polyurethane foam. Inspect installed elbows periodically for compression or damage and replace if the insulation integrity is compromised. Avoid prolonged exposure to direct UV light; if external exposure is expected, provide an appropriate protective covering.
