Ikram,

Few more information are required before your question can be answered.
1. What is the operating and design temperature of the pipeline?
2. What is the routing layout of the line?
3 What kind of support are used upstream of the nozzle?
4. Are you planning to take off the bellow permanently or temporarily? If it is a temporary arrangement it should not be much of an issue.

The tank nozzle can be reinforced to take the extra nozzle load. I believe that the expansion bellow is given to take care of the settling issue rather than the force. If the expansion bellow is taken off the line should be rerouted with better flexibility to take care of the settlement but expansion bellow is a better solution.
