That's questionable. From wiki [0]:
"A report in the Moscow Times quoted KGB veteran Vasily Pchelintsev as saying that there was a natural gas pipeline explosion in 1982, but it was near Tobolsk on a pipeline connecting the Urengoy gas field to the city of Chelyabinsk, and it was caused by poor construction rather than sabotage; according to Pchelintsev's account, no one was killed in the explosion and the damage was repaired within one day. Reed's account has also not been corroborated by intelligence agencies in the United States.
Another point of criticism of the sabotage allegations is that, according to Prof. V. D. Zakhmatov, an explosion safety expert who has overseen the safety measures on many of the Soviet oil and gas pipelines built in the 1980s, at the described timeframe Soviet Union simply didn't practice digital control of its pipeline system. Most of the control was manual, and whatever automation was used utilized the analog control systems, most of which worked through pneumatics."
