Length of the anti-freezing steam

In the north, preventing freezing and condensation in winter is the most troublesome issue. It turns out that our factory does not have specific requirements regarding the volume of steam released; it only requires that the steam be released without pressure, and the amount to be released can be determined at our own discretion, as long as it satisfies the satisfaction of the workshop or factory management. Generally, during the day when the temperature is relatively high, strict compliance is required; since there are more people around during the day. At night, when the temperature is lower, it’s okay to increase the setting a bit.

It depends on what type of line is used for anti-freezing and anti-condensation purposes. If it’s heavy crude oil, the vent size should be larger; if it’s light oil, then freezing of the steam isn’t a problem!

Generally, it depends on your own feeling; if the engine is turned up too high, there will be noise and the supervisor won’t like it. If it’s turned down too low, the engine will lose power after a while, and it may even freeze.

Our company requires that the steam injection length not exceed 10 centimeters. However, there is a difference between light oil and heavy oil: with light oil, heat tracing exhausts water rather than steam, while for heavy oil the maximum length should be 15 centimeters. To ensure prevention of freezing, employees increase the flow for 1–2 minutes during their hourly inspections and then restore it to its original setting. The steam used for fire suppression is released from the top at a moderate level, with the steam output being controlled at 10 centimeters

As long as it is vented without pressure, you can decide on the scale yourself – as long as it satisfies the workshop or factory management.

The steam length should not exceed 10 centimeters, and that of heavy oil should not be more than 20 centimeters.

Freezing and condensation prevention in the north during winter is the most troublesome issue, and it also constitutes a major part of outdoor inspections. If the degassing volume is too small, condensation lines will form; in mild cases this can damage the equipment and pipelines, while in severe cases it can disrupt normal production. We require that steam tracing drains be equipped with traps, that end-backflow valves be installed on the fire-fighting steam lines, and that exhaust steam not be discharged under pressure. After 8 p.m., the ambient temperature is too low, so the operators open the drain valves wider; they close these valves again at 8 a.m. It is important to save steam, but safe production is even more important, and all managers understand this. At night, it’s better for the freezing points of each row to be higher, as long as this does not affect the steam pressure of the system. The length of the steam is required to be no more than 10 centimeters, but this is quite difficult to control.

Our plant has no strict requirements; during the day, the operation level is kept very low, and it’s even possible to stop operation when the weather is good. At night, as the temperature drops, the operation level needs to be increased appropriately, but the heavy oil pipeline can be operated at a higher level
