Identification or tagging of supports on piping system is important for Tracking of Supports for Design, MTO and procurement point of view. Generally support tags includes primary function code of support, other auxiliary codes and dimensions. Here is a example tagging system for supports on a typical project.
Sample Support Function Codes
- A : Anchor
- B : Rigid support like saddle or shoe.
- C : Rigid support except saddle and shoe.
- D: Adjustable Support
- E : Adjustable support with low friction sliding plates.
- F : Axial Stop
- G : Guide
- H : Hanger with tie rod.
- S : Spring Support
- P : Post, portal and bracket, connections on reinforced concrete beam.
- SS : Protecting Plate
- R : Rigid support for pipeline valves.
- U : Rigid of saddle or shoe type for pipelines.
Company Standard Supports
Example : X-NN where X is function code as above and NN is support number from support standard for the project.
Example : B-11 : Clamped shoe for pipes NPS 1/2″ to 24″

Company Standard Structural Member Support
E.g. Tee-Post, U Frame, L Frame etc.
Example : P-04B-1200-1000 where P stands for portal, 04 support number in support standard, B stands for structural member size, 1200 is height of T-post, 1000 width of T-Post top member.
Supports standardized for the Project
Some supports are standardized for the particular project if they are not present in company standard but needs to be repeatedly used. Example coding system can be as follows :
JX-NN where J indicates it is project standard support, X is function code, NN is number given to that support.
e.g. JB-26
Special Supports
Some supports are unique to particular line at particular location. They are not repeated anywhere else in project. Example coding can be :
SPS-X-NNN where SPS means special pipe support, X is a funciton code and NNN is number given to that support in support register.
E.g. SPS-E-2021
Reinforcement Plates / Protection Plates
Example tagging system can be :
SS-NN where SS means reinforcement plate, NN is number given in company support standard.
Special Items Supports e.g. Springs
Special support items like springs can be given special codes e.g.
XX-NNN where XX can be code as follows :
- VS : Variable Load Spring
- CS : Constant load Spring
- SA : Shock Absorber
- RS : Rigid Strut
E.g. VS-027
Support Foundations
Sample coding for support foundations can be as follows :
E-2-1050-200 where E : foundation type, 2 : Plinth Type, 1050 : Plinth height, 200 is height above ground foundation.
