Benefit of Material to Systems Application

Carbon steel pipe has been a commonly used piping material on compressed air systems for many years.  It is accepted as a material for these systems in numerous codes, and it is the material of choice in common compressed air applications used for external pneumatic instrumentation with a relatively dry product air with a dew point between 40 and 50 °F.  Copper or stainless steel tubing and connections might be considered in smaller sizes due to the ease of installation.

System Application and Material Usage

In compressed air piping systems using oil-free compressors, corrosion-resistant piping should be used. A non-lubricated system may experience corrosion from the moisture in the warm air, contaminating products and control systems.   Depending on the system requirements, various grades of steel pipe can be specified.

The elongation properties of steel allow it to withstand stresses and strains without breaking under shocks from pressure spikes. In addition to long spools of pipe used in manufacturing facilities, shorter length and smaller size pre-fabricated nipples and fittings are also available for small systems or near equipment. This variation in configurations enables faster and more economical installations.  

Steel pipe is available in a variety of wall thicknesses with "light wall" or "standard wall" being the most common for use in compressed air systems. The system working pressure and pipe joining method will determine the required pipe wall thickness for each application.

Steel pipe may be installed using a variety of joining methods including grooved, welded, flanged, threaded and other mechanical joining methods.
