Rubber and Plastic Insulation Pipe

This Class 1 Grade Rubber and Plastic Insulation Pipe is a high-performance thermal insulation piping product, crafted with nitrile rubber and polyvinyl chloride as the core raw materials through sophisticated production processes including mixing, intensive mixing, extrusion and foaming. The optimal combination and full fusion of the two raw materials give the pipe excellent comprehensive performance, laying a solid foundation for stable application in various scenarios. The product has obtained a number of authoritative environmental and quality certifications such as UL GREENGUARD Gold, China Green Product and ROHS, and is produced in strict compliance with the national standard GB/T 17794-2021, fully ensuring its environmental friendliness, safety and standardized production and use.

It features outstanding thermal insulation performance, with a thermal conductivity coefficient of ≤0.030W/(m·K) at 0℃ and ≤0.031W/(m·K) at -20℃, and the thermal conductivity ranges from 0.029 to 0.033W/(m·K) in the -20℃ to 25℃ range, effectively reducing heat transfer and achieving efficient and stable thermal insulation. The pipe has a wide applicable temperature range of -50℃ to 110℃, which can maintain reliable adiabatic performance even in extreme cold environments, adapting to the thermal insulation needs of piping systems under different temperature working conditions. In terms of safety and flame retardancy, it meets B1 grade combustion performance standards, with an oxygen index of ≥32% (actual tested up to 42.0%) and a smoke density of only 46 (≤75). It has the characteristics of self-extinguishing without dripping fire after leaving the fire source, with 0s continuous combustion time and low temperature rise in furnace tests, which can effectively reduce fire risks and facilitate personnel evacuation and rescue in case of fire accidents, providing strong safety protection for piping systems.

Adopting a closed-cell structure, the pipe has excellent and long-lasting moisture-proof performance: its moisture resistance factor is ≥10000, water vapor transmission coefficient ≤2.8×10⁻¹¹g/(m·s·pa) (actual tested 9.40×10⁻¹²g/(m·s·Pa)), and vacuum volume water absorption rate is only 0.23%. This structure can effectively block water vapor penetration, keep the interior of the pipe dry for a long time, avoid performance degradation caused by moisture erosion, and greatly extend the service life of the insulation pipe. It also has the advantages of good flexibility and easy construction: with excellent elasticity and shock absorption performance, it can perfectly fit curved or irregular pipe sections, and is easy to cut and splice according to actual construction needs. No additional vapor barrier is required during installation, which reduces construction cost and difficulty, and the pipe can be reused after maintenance, greatly improving material utilization rate.

In addition to the core thermal insulation and safety performance, the pipe has a variety of practical additional advantages: it has good sound insulation and noise reduction effect, which can effectively reduce the noise generated by fluid flow in the pipe and create a quiet use environment; it has excellent anti-aging performance, with no cracks or deformation after 150h anti-aging test, and is resistant to ozone, acid and alkali erosion, which can maintain stable performance in harsh industrial and outdoor environments; it has no skin irritation, can prevent mold growth, and can effectively protect the inner pipe from corrosion, ensuring the normal and long-term operation of the entire piping system. In terms of dimensional accuracy, the pipe surface is flat without defects, and the overall size deviation is strictly controlled, with a compressive rebound rate of 83%, showing excellent mechanical strength and durability, suitable for high-frequency use scenarios.

With diverse specifications, the pipe has an inner diameter of 6-108mm, a wall thickness of 10-50mm and a length of 1800-2000mm, which can meet the thermal insulation needs of different fluid transmission piping systems. It is widely used in core fields such as HVAC pipes in buildings, hotels, schools and transportation hubs, cold and hot medium transmission pipes, industrial equipment adiabatic piping, as well as insulation piping for ships, chemical industry and agricultural facilities. Its efficient thermal insulation performance can reduce energy consumption of piping systems, safe flame retardancy and corrosion resistance can improve the safety and stability of piping operation, and diverse specifications and easy construction characteristics make it a reliable insulation solution for various engineering and industrial piping insulation projects.
