Safety Size Advisory - Safety Size Reaction Force Calculations

Tyco Valves & Controls has discovered an error in the calculation of reaction forces using the Safety Size program under certain conditions. We ask for your immediate attention to this matter and to follow the recommendations listed below. Failure to follow these recommendations could lead to serious bodily injury or property damage.

The reaction force calculation in Safety Size has a unit conversion error that results in a value that is approximately 22% of the correct value. This error only occurs on reaction force calculations set up with the following parameters regardless of the other settings:

A calculation using any other combination of these parameters, regardless of other settings, produces the correct value.

A copy of a typical Safety Size data sheet is included with this Advisory highlighting the pertinent inputs and the location of the erroneous reaction force output.

1. Customers who utilized Safety Size data sheets for pipe support designs using the above inputs should contact their local Tyco Valves & Controls sales office or authorized Tyco sales representative in order for us to provide a revised reaction force calculation.

2. All Safety Size users should immediately discontinue use of the reaction force values calculated under the above parameters. As an alternative procedure, reaction forces should be calculated using Newtons as the force unit. The resulting value can be converted to lbf by multiplying it by 0.2248 and added as a tag note to the data sheet.

While we realize most customers rely on the data presented in API RP 520 and/or ASME B31.1 to calculate reaction forces, this advisory is being sent as a precaution to alert those customers who may have used Safety Size to determine reaction force data under the above conditions as a precaution.

Safety Size will not be revised to correct this error since a new sizing and selection software program is presently under development and scheduled to be released later this year.

Tyco Valves & Controls regrets any inconvenience this may cause our customers, however, it is important that this Advisory’s recommendation be acted upon immediately.

Varec Sizing Beta Released to Public

The Varec Sizing Program [Beta] has been released for public download and testing.  We are very excited to bring this first preview of the program to our early Beta users. 

This program is still a work in progress so please provide us with feedback about things in the program that you like and dislike.  It is just as important for us to understand the things that this program does that helps you and makes your life easier as it is to know the things that cause you problems.  By understanding these issues we can better align our efforts to create a program that suits your needs.

Varec Sizing Beta Software

The Varec Sizing Program is currently being validated for Beta release. You can now read a little more information from the link to the Varec software. Once the program has been given the green light by our internal testing team we will make it available for those users who have signed up to be Varec Beta testers. If you would like to become a Varec Beta tester, please email Solution Development and request that you would like to be a Varec Beta tester.

Once the program is available an email will be distributed to those that have signed up with instructions on how to access the download. 

When it is determined that we will allow general downloads from the website, the download button will be enabled.  At that time we will also post an announcement on this page about the availablility.
