Rubber foam pipe can be used to insulate pipes and equipment. Due to the low thermal conductivity of the rubber-plastic insulation board, it is not easy to conduct energy, so it can be used for both heat insulation and cold insulation.

Rubber foam pipe can be used to protect pipes and equipment. The material of the rubber-plastic insulation pipe is soft and elastic, which can cushion and absorb shock. The rubber-plastic insulation pipe can also be waterproof, moisture-proof and corrosion-proof.

Rubber foam pipe can play a decorative role on pipes and equipment. The appearance of the rubber-plastic insulation pipe is smooth and flat, and the overall appearance is beautiful.

Rubber foam pipe has very good stability and can play a good role in preventing fire.

Rubber foam pipe is flexible, so it is easy to install when it needs to be bent.

Frequently Asked Questions

What are the primary uses of rubber foam pipes?

Rubber foam pipes are designed to insulate and protect pipes and equipment. Due to the material's low thermal conductivity, it prevents easy energy transfer, making it highly effective for both heat insulation and cold insulation.

How does rubber foam pipe protect pipes and equipment?

The rubber-plastic insulation material is soft and elastic, allowing it to cushion and absorb external shocks. Additionally, it offers waterproof, moisture-proof, and corrosion-resistant features to safeguard pipeline systems.

What is the fire rating of this insulation material?

The rubber foam insulation material has excellent stability and high fire safety performance. It meets the Class 0 & Class 1 standards when tested according to the BS 476 Part 6 & Part 7 methods.

Is rubber foam insulation easy to install around corners?

Yes, rubber foam pipe is highly flexible. This elasticity allows it to be bent easily, simplifying the installation process around complex bends, corners, and pipeline shapes.

What temperature range can the rubber foam insulation withstand?

According to standard technical tests (GB/T 17794-1999), this rubber-plastic insulation material functions reliably within a temperature range of -50°C to 110°C.

How does the material perform against weathering and fungi?

The material demonstrates excellent environmental resistance, earning "Good" ratings for fungi resistance (ASTM 21), ozone resistance (GB/T 7762-1987), and resistance to UV and weathering (ASTM G23).
