The API RP-14E describes an approach to Calculate API RP 14E maximum allowable erosional velocity for platform piping systems. The API RP 14E equation The most known empirical model is presented in the API Standard RP 14E, or its modified version proposed by Salama et al. Find the most up-to-date version of API RP 14E at GlobalSpec. e m C V ρ (1) where V e is fluid erosional velocity, ft/s; C (100 for continuous service, 125 for intermittent service for both solid-free flowing fluid, and reduced value if solid particles are present) is an empirical constant; ρ Calculate API RP 14E fluid velocity and flowrate for single phase gas, single phase liquid, two phase gas liquid, and three phase gas, oil and water (black oil). Erosion velocity Basis of the API RP 14E Erosional Velocity Equation The basis and the source of this API RP 14E equation 关1,2兴 have been the subject of speculation in several papers and reports. The American Petroleum Institute Recommended Practice 14E (API RP 14E) describes a method for calculating an "erosional" velocity, a threshold velocity at which it is presumably safe to operate. δ. For applications outside these pressures and According to the American Petroleum Institute's (API) RP 14E standard for erosional velocity limits, the maximum allowable gas velocity limit suggested by the API is calculated using the following The current practice for eliminating erosional problems in piping systems is to limit the flow velocity Ve to that established by the recommended practice API RP 14E based on an empirical constant (C-factor) and the fluid mixture density ρm as follows: Ve=C/ρm. The widespread use of the API RP 14E erosional velocity equation is a result of it being simple to apply and requiring little in the way of inputs [26], [27]. The American Petroleum Institute Recommended Practice 14E (API RP 14E) guide describes a method for calculating an erosional velocity for clean service. The API criterion is specified for clean service (noncorrosive and sand-free), and it is noted that the C clear guidelines on how to determine the maximum operating velocity when corrosive fluids are present. The widespread use of API RP 14E is a result of it being simple to apply and requiring little in the way of inputs.
