Almost every processing facility needs cooling. If steam is coming in, or doing any kind of heating, you have to take the BTUs out at some point. A cooling tower is, in essence, a heat exchanger. It rejects waste heat to the atmosphere by using air and water in direct or indirect contact to remove process heat

Designing Compressed Air Systems - FluidFlow FluidFlow

Jun 19, 2018 · The compressed air pipe routing, design and dimensions are important factors for the efficiency, reliability and cost of compressed air production. Occasionally, a large pressure drop in the piping system is compensated by adjusting or increasing the working pressure of the compressor from for example, 7 bar to 8 bar. Expansion Loops on the Piping or Pipeline Systems What Piping expansion loops are widely used in long runs of pipes running over the pipe racks or sleepers. Pipeline expansion loops are usually provided at every 500m length as the design temperature of pipelines are normally less as compared to piping systems. Fig

Water hammer Be aware of potential water hammer problems. This is particularly serious for large piping systems such as are installed in municipal water supply distribution systems. These systems are characterized by long gradually upward sloping and then downward sloping pipes.

Improving Chilled Water Piping Distribution

Chilled water remains a popular cooling medium; however leaks in the piping systems are a threat to trench is sized depending on the diameter and quantity of the chilled water pipes running in it. to the infrastructure needed to route the piping and the difficulty to add an extra pipe line to the main header once the room is in operation. Modeling the Uniformity of Manifold with Various

  • AbstractIntroductionMethodologyResult and DiscussionsModel Validation Using Experimental DataConclusionsThe flow distribution in manifolds is highly dependent on inlet pressure, configuration, and total inlet flow to the manifold. The flow from a manifold has many applications and in various fields of engineering such as civil, mechanical, and chemical engineering. In this study, physical and numerical models were employed to study the uniformity of the flow distribution from manifold with various configurations. The physical model consists of main manifold with uniform longitudinal section having diameter of 10.16cSECTION 23 65 00 - COOLING TOWERS PART 1 - 1.

    Pipe Rack Design and Calculations - Make Piping Easy

    Feb 02, 2021 · Rack height is calculated considering branching from the bottom and top on both sides. The clearance below the first tier or lower pipe should be a minimum of 2.2 m as per the headroom. The standard Pipe rack height for the first tier is 4.5 m. The standard tier to tier height is 3 m (thumb rule) Plant Engineering Four causes of water hammer, and how Aug 04, 2016 · Solutions:Connecting into the condensate header All condensate system branch lines must be connected into the top of the main condensate header:there is no exception. The condensate connection is at the top on the horizontal condensate main header and never into a vertical condensate header.

    Steam Distribution System - an overview ScienceDirect Topics

    Stephen Hall, in Branan's Rules of Thumb for Chemical Engineers (Fifth Edition), 2012. Steam Traps. Steam traps inevitably fail. They fail open, blowing steam directly to the condensate system. They fail closed, potentially resulting in condensate backing into steam pipes and process equipment and causing mechanical damage or reduced heat transfer. Steam Mains and Drainage Spirax SarcoBranch Lines. Branch lines are normally much shorter than steam mains. As a general rule, therefore, provided the branch line is not more than 10 metres in length, and the pressure in the main is adequate, it is possible to size the pipe on a velocity of 25 to 40 m/s, and not to worry about the pressure drop.

    Steam Piping Best Practices CleanBoiler

    A general rule of thumb is that 1 psi of steam will raise water about 2 feet. For example, a 5 psi system should not have condensate lines higher than 10 feet above the steam trap. Properly Size Steam Trap Drip Leg Lines. Not only must steam traps be piped off the bottom of the steam lines, the pipe Underground Piping conceptsThe piping system is taken underground generally for the utility services like cooling water supply to various units and cooling water return to cooling tower for line sizes normally 18 inch NB and above, other water services with big pipeline sizes, big oil supply lines and various sewer systems in the process units of the chemical, petrochemical and refinery type of plants. The term underground applies to the

    Oct 02, 2017 · ily chilled water and condenser water system piping system design, it is important to understand the evolution from 1-pipe into the other three systems, all of which are used for heating as well as cooling. 1-Pipe Systems A 1-pipe water distribution system is a system that has a one main pipe looping around the building and then returning.Piping branch flow calculations - Pipelines, Piping and Dec 09, 2009 · A "rule of thumb" is for the cross-sectional area of the header to be equal to the sum of the cross-sectional areas of the in-coming or out-going branches. That would suggest 3" in your case, but be careful, it doesn't take the length of the header or flow variations in certain branches
