Product Application
Excellent Performance

The insulated pipe is made of NBR and PVC. It doesn't contain fibrous dust, benzaldehyde and chlorofluorocarbons. Moreover, it has low conductivity & heat conductivity, good moisture resistance, and fireproof.

Widely Used

The insulated pipe can be widely used in cooling units and equipment of central air conditioning, freezing water pipes, condensing water pipes, air ducts, hot-water pipes and so on.

Easy Installation

The insulated pipe not only can be easily installed with the new pipeline, but also can be used in the existing pipeline. The only thing you need to do is to cut it, then glue it. It does not negatively influence the performance of the insulated pipe.

Frequently Asked Questions
1. What materials are the insulated pipes made of?
The insulated pipes are made of high-quality NBR (Nitrile Butadiene Rubber) and PVC (Polyvinyl Chloride). They are free from fibrous dust, benzaldehyde, and chlorofluorocarbons, ensuring a safe and clean installation.
2. What are the key performance benefits of these insulation pipes?
They offer low thermal conductivity, excellent moisture resistance, high fire protection ratings (Class 0 & Class 1), and stable performance across a wide temperature range from -50°C to 110°C.
3. What applications are these insulated pipes suitable for?
They are widely used in air ducts, freezing water pipes, condensing water pipes, hot-water pipes, and cooling units or equipment of central air conditioning systems.
4. How are the pipes installed on existing pipelines?
Installation is highly flexible. For existing systems, you simply cut the insulated pipe, wrap it around the pipeline, and glue it. This process is quick and does not affect the overall insulation performance.
5. What size options and configurations are available?
The wall thickness ranges from 6.25mm to 50mm, and the inside diameter ranges from 6mm to 89mm. They are supplied in standard lengths of 6ft (1.83m) or 6.2ft (2m).
6. How resistant are the pipes to environmental factors like UV and ozone?
According to standardized testing methods (such as ASTM G23 and GB/T 7762-1987), the insulation material offers good resistance to UV rays, weathering, fungi, and ozone.
