The system in place must be described in a clearly-visible posting.

This format was in place in the previous revision of the guideline, so many engineers are already familiar with it. After all, the last revision of the IIAR guideline was inand technology has changed here and there over the last 23 years!

The same system must blletin across the entire facility. View Our Full Product Index. Directional arrow tape may also be applied around the full circumference of the pipe.

Since these requirements were also part of the old standard, your facility is probably already in the safe zone. Naturally, anhydrous ammonia pipes were considered hazardous, and got yellow labels. Printed in black Physical State Section: All Brimar products are manufactured in the USA. That standard, created by the American National Standards Institute ANSIrecommended a color code for pipe labels that indicated the type of contents with a color.

The revision contains 28 abbreviations versus 17 contained in the Guidelines.

Revised Guidelines for Ammonia Systems. Component markers will bear the name of the equipment they identify, e.


IIAR Bulletin #114

Over 8″ Legend Size: Pressure equal to or bulltin than 70 psig will be considered to be low pressure and printed in black on a green band. If not, now is a great time to iir it!

A reference chart that fully explains the ammonia refrigeration piping and component identification markers, including the approved abbreviations, should be placed in areas that are conspicuous to operating personnel. Pipe markers in accordance with Bulletinare designed to identify the refrigerant contained within that piping segment i. Over 10″ Legend Size: Inthough, the standard was revised.

There are two requirements for these alternate schemes: Therefore, on-site decisions will be necessary to provide the optimum pipe marking system. The color schemes may also be applied to portions of the refrigeration system beyond machinery rooms. The reference chart, legend, or key should be made of durable material that will remain legible. The following chart shows the recommended pipe marker letter height and marker size based on the outside pipe diameter of the pipe to be identified and the distance between the viewer and the pipe.

In addition to the abbreviation, the use of a temperature or a pressure commonly associated with a particular line may further assist the operator. Standardized abbreviations are used, and each section is printed in a specific way.

In addition, component markers will be provided with a pressure level designation. Wrap-around, strap-on, and EZ stick-on markers for piping and components. Yellow pipe labels were used to mark any pipe containing a hazardous material. In either case, the directional bulltin or arrowhead will be BLACK in color and proportionate in size to the marker.


Ammonia refrigeration is a powerful technology, but these large systems are complicated and can be dangerous. In those areas where state codes and government regulations iia not conflicted, ammonia refrigerated facilities have the option to implement a company documented piping color scheme.

Do the changes to the standard mean that you need to replace all of your existing labels? The guideline specifically allows alternative color schemes, such as the one used in the older version of the IIAR standard — or any other color scheme that works well for your facility. Directional arrows will be printed on the marker body. The “self-adhesive” type of marker will be printed with one directional detachable arrows.

As a whole, though, the recommended label format has kept its shape. Abbreviating the names given to pipes in the ammonia refrigeration system will assist the operator in identifying and tracing the system. Track Order Sign In. Detachable arrow printed in black. Wafer Seals and Mailing Seals.
