... and 90° bend pipe sections. Erosion test is performed with duration of 425 hours for bend pipe and 1275 hours for straight pipe. Thickness loss is obtained by measuring the carcass sections with a metallographic microscope. The results show the higher erosion rates appear at the leading edge of the inner...

..., elastic support can significantly reduce the impact response of the single-span straight pipe, but it is not obvious for the tee pipe. The result indicates that only the satisfactory arrangement of elasticity support can achieve the purpose of vibration attenuation and shock absorbing. NUMERICAL...
