By Muthuramalingam Ganapathy, WS Engineering & Fabrication, Singapore, Harikrishnan Lakshminarayanan, Prashanth Sundarraj and Chandragupthan Bahubali, Wood India Engineering & Projects, Chennai, India   Oil and gas facilities handle multiphase fluids with sand or without sand. According to industrial experts, many causes for erosion include multiphase flow with sand or without sand, droplet impingement, slurry flow, cavitation and droplet flash.    Droplet impingement (water droplet erosion/liquid impingement erosion) is usually encountered by the impact of high-speed water droplets in gas lines. Cavitation erosion occurs in liquid lines wh
