Frequently Asked Questions
How do I choose the correct PVC external protection model?
You should select the matching model from our specification tables based on your pipe diameter, insulation thickness, and the specific bending radius in the field. For customized or special-shaped structures, please contact us directly via email.
What is the temperature limit for these PVC cladding materials?
Our composite PVC external protection system is suitable for 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 are the fire safety ratings of Aohuan PVC materials?
According to ASTM E84 testing standards, our material achieves a flame spread index of ≤25 and a smoke developed index of ≤50, ensuring high safety and flame retardancy.
How long is the service life of the PVC external protective cladding?
Under normal field application conditions, the actual service life of our composite PVC-based external protection material exceeds 10 years.
What industries are suitable for Aohuan PVC protective systems?
They are widely applied in microelectronics, photovoltaics, food & beverage, biopharmaceuticals, petroleum, chemical processing, commercial and civil buildings, and offshore oil drilling platforms.
Does Aohuan provide custom designs and technical support?
Yes, we provide full technical support including choosing systems for specific working conditions, technical reforms of existing insulation, custom tailored structures, and product maintenance training.
