Natural gas pipeline crossing issues
Thread Content
Now, a gas pipeline needs to be laid across, and seamless steel pipes with a diameter of DN100 will be used for this purpose. I would like to ask what wall thickness is appropriate for such seamless steel pipes.
Select the wall thickness based on pressure, and also consider the spacing between support points during traversal
Consider the design pressure of the gas; for medium pressure, 108*5 is usually sufficient. A reinforced concrete sleeve can be used when passing under municipal roads
It mainly depends on the design pressure and the conditions at the construction site
When going through, one thing to consider is the wall thickness; another key factor is the anti-corrosion coating and the sacrificial sleeves at the joints
