When you see your regulator and valves freezing over, it is easy to blame the weather. In many natural gas applications, though, pressure drop, cold gas, and moisture usually create the freeze-up. Natural gas can cool quickly when it moves from high pressure to lower pressure. If moisture is present, that temperature drop can create frost, ice buildup, or hydrates around regulators, valves, pilots, chokes, and pipeline equipment. Cold weather can make the problem worse, but it is not the only cause. Large pressure drops can create freezing conditions even during warmer months. With the right heating solution, operators can manage

A quiet night in the field turned into a frozen nightmare by morning. A single regulator froze solid, halting flow and production — a reminder that in the oil and gas world, freeze-ups don’t wait for tomorrow.
