8. FIELD ENGINEERING EVALUATION – SI58

Evaluator: Kevin Wilson – Field Engineer Date: 8/24/11
Unit: 2 Building: Turbine Elevation: Floor El. 649’
Location: Between Col. Rows “D” and “H” and Col. Rows “T9” and “T11”

Problem Description:
There is an 8” Pipe running from condenser at a location approx. 16’ West of Col. Row “E” to the south and
then parallel to Col Row “T11” then thru a penetration in the floor to El. 629’. The pipe has no permanent or
temporary supports installed. There are only cables and turnbuckles installed. There is also a 6” pipe that
runs parallel to the 8” pipe. The 6” pipe has some permanent supports installed, but it lacks about 3 of them. It
is also suspended by cables.
Evaluation Summary:
The piping is 8” Sch. 120 which weighs 60.63 lbs./lin. ft. The 6” piping is assumed to be Sch. 120 as well and
weighs 36.39 lbs/ lin. ft. The loads are calculated based on those assumptions. The loads calculated for each
support are shown on SI58_Sketch_1. New supports should be installed as shown on the attached sketches.
