Frequently Asked Questions
How do I choose the correct PVC external protection model?
You should select the corresponding model from our reference tables based on your specific pipe diameter, insulation thickness, and bending radius in the field. For customized requirements, special models can be designed by contacting us directly.
What is the temperature limit for Aohuan composite PVC external protection materials?
Our protective materials are suitable for pipelines and equipment systems operating between -37 ℃ and 260 ℃. However, the outer surface temperature of the insulation layer must remain below 66 ℃ (with a national standard recommendation of under 50 ℃).
What fire safety standards do Aohuan PVC materials meet?
Aohuan composite PVC materials are highly flame-resistant. According to ASTM E84 testing, the flame index is ≤25 and the smog index is ≤50, meeting strict commercial and industrial safety standards.
In which industries can these PVC outer protection systems be applied?
They are widely used in microelectronics, photovoltaics, food & beverage, biopharmaceuticals, petroleum, chemical plants, oil drilling platforms, as well as commercial and civil building installations.
What is the expected service life of Aohuan PVC protective systems?
Thanks to their robust physical properties and aging resistance (ASTM E96 tested), our composite PVC materials offer a proven actual service life of more than 10 years.
