Compressed Air Piping Design

Compressed air piping systems michael frankel cipe utility systems consultants somerset nj introduction compressed air is an often used utility system found in facilities.

Compressed air piping design.

It is used to do work by producing linear motion and actuation through a piston and cylinder or adiaphragm forair actuated valves doors dampers brakes andso forth atomizing. Compressed air pipe size table. Pressure loss through piping. Along the way there is a risk of contamination and pressure drops.

Excessive velocity can be a root cause of backpressure erratic control signals turbulence and turbulence driven pressure drop. Pipe sizing by velocity. Air flow rate through piping. The british compressed air society suggests that a velocity of 20 fps or less prevents carrying moisture and debris past drain legs and into controls.

Now measure or calculate the total length of your compressed air pipes and look it up in the top row. Owners of compressed air piping systems tend to focus on the compressor and think of the piping as less of a concern. In a piping system where a feed line of compressed air is trying to feed into another air line the turbulence caused by a 90 entry can cause a 3 to 5 psi pressure loss which increases the operating costs. Inefficient compressed air distribution systems result in higher energy bills lower productivity and poor air tool performance.

Once air is compressed dried and filtered it is sent to an end use. Air velocity through piping. Air flow rate through a valve. Pipe diameters of 3.

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. Air flow rate through an orifice. Piping is a vital component in a compressed air system. Piping systems more than five years old have been shown to exhibit leaks of up to 25 percent yet many facilities are slow to upgrade equipment to the latest technology.

Now instead of giving you complicated formulas to calculate the pressure drop here is a simple table that will answer all your pipe sizing questions. The compressed air pipe routing design and dimensions are important factors for the efficiency reliability and cost of compressed air production. May 15th 2020 at. However just as hearts can fail due to clogged arteries compressors can fail due to poor piping.

Guide to compressed air piping systems last updated on. Condensate load from compressed air. Look up your compressors maximum flow rate in the left column. Ambient air s impact on compressed air system performance 2 part of the scope of this paper.

The most overlooked idea in piping layout and design is air velocity. One of the simplest fixes in a compressed air system is to replace tee connections with directional angle entry connections. Pipe sizing by pressure loss. Saturated humid air table.
