“The unstable soil conditions surrounding the pipe was the main cause of the explosion,” said Husdin Che Amat, department director for petroleum safety.
“The (gas) pipe met the technical standards used in the installation,” he told a news conference late on Monday (Jun 30).
“But the failure is due to cyclic loading … resulting in gas leakage and metal friction between pipes causing the ignition and explosion,” Husdin said.
The affected area is part of a 2,680km-long gas pipeline operated by state-run oil and gas firm Petronas.
Selangor state police chief Hussein Omar Khan said law enforcement found “no elements of negligence and sabotage” after probing the disaster.
