Zusammenfassung:•MHD pressure drops of PbLi flow in a double-bended pipe under B = 0.5T–3.0T, Re = 2,000–200,000 and Ha = 106–640 were measured.•MHD pressure gradient of PbLi flow in the double-bended pipe showed a linear relationship to the product of mean velocity and B2.•Effective load resistance Kp of PbLi MHD flow in the double-bended pipe was 25% larger than the theoretical value.•All the MHD friction loss coefficients fMHD were well correlated with the interaction parameters (N = Ha2⁄Re) in the range of 0.1
