Corrosion protections of underground pipelines are performed by corrosion protective coatings and cathodic protection system at the same time. Polyethylene is the most common coating system to be used protection of water, oil and gas pipelines in Iran. APPOL product from abhar polymer compounds is based on high density polyethylene, which used in order to protect corrosion in the pipeline industries. APPOL features inglide:
-Excellent Strength and toughness in wide range of temperature (-30 to 85°C)
-High resistance to sunlight and weather conditions -Excellent resistance against chemical agents, water and oxygen -Very good mechanical properties and resistant to stresses caused by soil and environmental factors
-Very low consumption of electrical energy at cathodic protection due to good dielectric properties
