Description
Summary:Analysis of the patent for a wear-resistant knuckle bend in a gas–oil pipeline shows that one of the claims presented there is incorrect. Theoretically, it is established that the introduction of a protective vane within the knuckle bend improves the gas dynamics close to the problematic wear zone at its wall. Manufacture of the vane from steel strip by complex deformation is shown to be economically viable.
