Latest Patents

Klopffer's latest patents include a method for testing the integrity of a flexible tubular pipe and a device for implementing the same. This method is specifically designed for pipes that carry hydrocarbons. The pipe features at least one internal sealing sheath made of polymer material, which incorporates elements of a reactive compound. These elements are capable of reacting with corrosive gases contained in the hydrocarbons that diffuse radially through the sheath. The reaction forms a first layer that extends radially from the internal surface, where the elements of the reactive compound have reacted with the gases. A second layer exists between the first layer and the external surface, where the elements of the reactive compound have not yet reacted with the gases. The method employs ultrasound technology to determine the position of the interface between the first and second layers, allowing for the measurement of gas diffusion progression through the sheath.
