Winter pressure testing
Thread Content
Dear colleagues, for our projects in the Northeast, construction takes place in winter, and during pipeline pressure testing and water testing, freezing can occur. As for gas testing, it relates to the brittle transition temperature of carbon steel. How do you carry out pressure testing in winter? ? ?
During winter construction, when temperatures are too low, we use methanol, but it is necessary to ensure its proper recovery and protection.
The fifth floor is the correct answer. In the winters of the northeast, carbon steel pipes are very likely to burst due to pressure tests
People underestimate the winters in the Northeast too much; just look at the severity of the cold – here’s a GIF to show you. Antifreeze is still recommended.
Back in my hometown, I used to often play with ice lanterns. Take a tin bucket, fill it with water, place it outside, sleep for a while, then take it back to the room and melt it – and you’ll end up with an ice lamp.
