When selecting insulation materials (such as self-adhesive rubber insulation cotton) suitable for Huaneng air conditioning and solar energy according to your needs, it is necessary to comprehensively consider the inner diameter of the pipeline, budget, and the performance of the material itself. The following is a shopping guide compiled based on these key factors.

Select based on the inner diameter of the pipeline

The specifications of Huaneng insulation materials need to match the inner diameter of the pipeline to ensure tight wrapping and achieve the best insulation effect. Common pipe sizes (such as 4 minutes, 6 minutes, 1 inch, etc.) correspond to different inner diameter ranges. For example:

4 Responsibilities: Inner diameter of about 15mm, suitable for indoor pipelines of low-power hanging machines.

6 Responsibilities: Inner diameter of approximately 20mm, suitable for most household air conditioning ducts.

1-inch pipe: with an inner diameter of about 25-34mm, commonly used in solar hot water pipes or central air conditioning branch pipes.

Large diameter pipelines (such as those with an inner diameter of 120mm or more): Thickened or customized specifications, such as insulation cotton with a wall thickness of 50mm, need to be selected.

Material and performance recommendations

Rubber insulation cotton: closed cell structure, waterproof and moisture-proof, suitable for air conditioning refrigeration pipes and solar water pipes. Prioritize choosing B1 flame retardant grade to avoid gray inferior cotton (which may contain formaldehyde).

Aluminum foil composite type: Strong sun protection performance, suitable for outdoor exposure of solar pipes.

Thickness selection:

6mm: limited to indoor low-power air conditioners only.

9-13mm: Recommended thickness for household air conditioners.

Above 19mm: Thickening is required for commercial or low-temperature environments.

Installation precautions

To avoid the failure of self-adhesive adhesive: It is recommended to use zip ties to fix it, especially for outdoor parts.

The welding point must be wrapped to prevent condensation water from corroding the copper tube.

Outdoor protection: Wrap aluminum foil tape to prevent sunburn and rain.

Service and Support

Pay attention to platform services when making purchases, such as JD's 7-day no reason return and price guarantee for most products, and Jingxi's self operated store providing lightning refunds.

summary

When selecting, it is necessary to clarify the inner diameter and budget range of the pipeline, and give priority to rubber material (B1 flame retardant) and appropriate thickness. If the budget is limited, mid-range brands such as Huaneng Thermal Insulation can be selected; If long-term durability is required, it is recommended to use thickened or aluminum foil composite type. Pay attention to the fixing method and protective measures during installation to ensure long-lasting insulation effect.
