Previous attacks have disrupted gas deliveries to both destination countries several times
The blast occurred 40 kilometres (25 miles) west of the town of al-Arish in the north of the Sinai peninsula, a security source said.
The pipeline, which carries gas through the Sinai and on to Jordan and Israel, had already been attacked six times since former president Hosni Mubarak was toppled in February.
Witnesses said they had seen armed men at the scene, the source said. He did not know if there had been any victims.
Previous attacks have disrupted gas deliveries to both countries several times, but it was not immediately clear what impact the latest incident would have.
