Abstract
A high pressure pipe of high density polyethylene material includes an internal lining (3), an intermediate reinforcement layer (2) and an outer cover layer (1). The high density polyethylene material of the internal lining (3) is filled with a filling material (5). As a result, the mixture of high density polyethylene and filling material provides resistance against higher temperatures, allowing the pipe to be able to transport fluids at elevated temperatures.
Claims18
