Thank you Mariog for the response. I fully agree with you. I did tweak the cold load a little but not as much that my system will have high deflection in cold position. The maximum deflection in the system (spring hanger location) after I tweaked the cold load is around 1.2mm which is negligible.

Also as per L.C Peng, Industry standards [5] limit the load variation to no more than 25%. This means that, regardless of the pipe movement, the spring will carry no more than 125% and no less than 75% of the properly balanced portion of load. The unbalanced load will be shifted to the neighboring supports or equipment.
In actual applications, a smaller design load variation may be specified for critical piping systems,such as the ones operating at creep range or connected to rotating equipment.
