Economical & Optimized Procedure Of Process Pipe Sizing For Industries Based On Fluid Velocity
Pipe lines are generally used in various industries i.e. Refinery, Power Plant, Textile, Food Processing industries etc. for Power, Process, Utility, HVAC, Cross Country Transmission of Gases, Liquid & Dual phase fluids as per their requirements. Pipes are designed on the basis of various parameters such as pressure, temperature and velocity of fluid flowing through it. This paper examines unmethodical procedure for line sizing with critical thickness method, assessing an experimental approach over a steam line, having a material of construction ANSI B-36.10, A106 Gr-B, seamless pipe, operating at temperature of 200⁰C, by following the velocity based line sizing method with a trial and error approach. Many cases are considered in this trial and error approach, where their resultant velocities are compared with an optimal velocity, which is selected based on fluid characteristics and pressure, to find out a proper pipe line size. Pipe sizing in industries is mostly done on the basis of past experiences rather than a standard procedure. Due to which immense amount of capital has to be invested in the initial phase of plant installation or during future expansion when the revenue from the industry is inconsiderable. Even after overdesigning, the corrosion of pipe occurs and due to which life of pipe reduces. That is why pipe designers sometime provides factor of safety more than what is required. The overall objective of this paper is to standardized a methodological procedure for line sizing based on velocity and thereby providing a supplementary tool for pipe designing.
