I need few clarifications regarding Pipelines

1) Why is it economical to transport gas at the lowest temperature possible?
2) Why Stress problems in low temp gas pipelines are less severe than that in an oil line?

Any thoughts regarding above clarifications.

It varies from case to case. Not always the transportation of gas at lower temperature is economical. It primarily depends upon the climatic conditions of the area where gas is being transported.
Stresses in pipelines are mainly due to the internal pressure and temperature conditions. Explain a bit what are you asking for?
