Polyurethane casing centralizer, also known as polyurethane drilling centralizers, is the cable accessory used during the installation of pipes (casing) in oil or natural gas Wells. its primary function is to ensure that the casing is in the correct position in the wellbore and to keep it in the desired position in order to successfully complete the casing sinking process.
The polyurethane casing cntraliser is made of advanced composite materials with a low coefficient of friction, heat resistance and is extremely durable. The composite works dependable even under extreme borehole conditions. The polyurethane material, in contrast to many plastic centralizers, is more extremely wear-resistant and able to sustain high impact loads.
