Frequently Asked Questions
How much does a 100-foot steel pipe expand per 100°F temperature rise?
A 100-foot carbon steel pipe expands approximately 0.78 inches (20 mm) for every 100°F (55.6°C) rise in operating temperature.
What is the purpose of pipe guides near an expansion loop?
Pipe alignment guides ensure the straight pipe expands purely in a straight axial direction into the expansion loop, preventing lateral buckling or column bowing.
How far should the first pipe guide be placed from an expansion loop elbow?
Under standard piping practices, the first guide (G1) should be placed no further than 4 times the nominal pipe diameter from the loop elbow to allow free cantilever flexing.
Can expansion joints be used instead of expansion loops?
Yes, bellows or slip-type mechanical expansion joints can be used where ceiling space is too cramped for loops. However, pipe loops use standard pipe and elbows with zero packing seals, making them virtually maintenance-free.
