Gulf Perlite Pipe Sections are a pre-formed, high-temperature, corrosion resistant, water repellent, pipe and block insulation section, uniformly reinforced with a high strength fiber for use on systems operating up to 1200°F (650°C) as per ASTM C-610 suitable for high-temperature pipe insulation, e.g. Sulfur Conveying Lines. Gulf Perlite Pipe Sections are an inorganic, non-combustible section which meet and exceed the physical property requirements of ASTM C-610.
Gulf Perlite Pre-Formed Insulating Pipes inhibit corrosion and are rigidly strong resisting damage.
Gulf Perlite Pre-Formed Pipes prevent the accumulation of Chloride Ions that may penetrate and corrode the pipes. They also resist against formation of acid and alkalis attacks.
Day 1, Installation of Gulf Perlite Molded Pipe Insulation
Day 84, Subjected to cycle conditions(e.g.:temperature, weathering and saline water) to accelerate corroding
Perlite Insulated segments displays minimal corrosion
