Thermal expansion refers to the tendency of matter to change in volume in response to a change in temperature. Stainless steel pipes has a thermal expansion of 4.6 inches/100 feet at 400 degrees Fahrenheit.
Materials expand cold shrink when heated. Pipeline is not immune to these natural laws, so they will also vary with temperature expansion and contraction.

thermal expansion depends on Temperature and material of steel
For thermal expansion of the pipe, avoiding damage/clash to adjoining pipes.
Low resistance to fire, and high thermal expansion.
Yes. The expansion loop is only there to take up the thermal expansion of the pipe run, installing a valve will not impede the action of the loop.
The answer depends on what causes the elongation: a stretching force (tension) or thermal expansion.
high thermal expansion
This increase of volume is called expansion
The coeifficent of expansion per degree can be found in the manufacturers charts
As current passes through steel, it heats up from resistive heating. As it heats up, it expands. A typical coefficient of thermal expansion for steel is 13x10-6 m/m K but the exact coefficient of thermal expansion of steel depends on the type of steel. For example:Coefficient of Linear Thermal Expansion for:(10-6 m/m K)(10-6 in/in oF)Steel13.07.3Steel Stainless Austenitic (304)17.39.6Steel Stainless Austenitic (310)14.48.0Steel Stainless Austenitic (316)16.08.9Steel Stainless Ferritic (410)9.95.5
In a pipeline system, expansion loops, which may actually be ahorseshoe or w-shape besides a loop, provide a tolerance for the pipe when it experiences a thermal expansion or contraction.
6.3 in/in.°F or 11.3 µm/m.°K
To save the piping from breaking during thermal expansion (day/night, summer/winter). They provide the needed space to expand withought breaking the system.
