Fiber reinforced plastic (FRP) pipeline has better anti-corrosion and anti-scaling performances than traditional steel pipeline. It has been widely used in the areas of liquid transmission. In view of the water hammer phenomenon in liquid pipeline with entrapped gas, water hammer analysis model for the FRP pipeline is built. The solve methods are discussed based on homogeneous flow model and method of characteristic (MOC). A computer program is developed to research the pressures response. Ultimately, this paper simulates the water hammer pressures response on the conditions which include different initial void fraction in liquid, a constant liquid level at upstream end and sudden closure of valve at downstream end of pipeline. The study results are benefit to guide safe operation and management of FRP liquid pipeline.
