In reply to the discussion: Multiple Suspected Gas Explosions In Lawrence, Andover And North Andover [View all]Xipe Totec
(43,866 posts)12. I worked for one of the gas transportation companies some decades ago
We had a line blow up in Katy, Tx. There was a pillar of fire coming from the site of the explosion that was 100s of feet high. There's so much gas on the lines, and at such high pressure, that almost an hour elapsed before the pipeline pressure monitors began to register a drop in pressure.
The gas is compressed to near the triple point for methane, meaning the gas is close to the solid, liquid, and gaseous state. Any water vapor in the line instantly combines with the gas to form a solid methane hydrate.
The pressure on those lines is mind boggling.
