Abstract:
A centralizer for tubular elements is provided which includes an inner part formed by a first material having high mechanical performance and chemical stability and an outer part arranged on said inner part, formed by a second material. The second material may be an autolubricating material. The second material may further possess a low coefficient of friction. The second material may additionally possess lower mechanical performance and chemical stability than the first material.A method of manufacturing the centralizer is also provided, including steps of injecting the first material on a tubular element to form the inner part on the tubular element and injecting the second material to form the outer part on the formed inner part.
