Ultra-high temperature Polyketone lining tubing
In order to solve the anti-corrosionand anti-wear problem in the high temperature section of oil & water wells,the company has developed a new type of eco-friendly high-temperature lining tubing ,the lining material is Polyketone which is madeof carbon monoxide and olefin.
Material Characteristics：
∙Excellent chemical resistance, oilresistance and hydrolysis resistance
∙Excellent abrasion resistance
∙Low water permeability and low gasbarrier properties
∙Vicat softening temperature reaches205 ℃, and the working temperature can reach 130 ℃ -140 ℃.
∙Excellent impact resistance at wideapplication temperatures
∙Green and eco-friendly, Withoutharmful substances
