Threaded joint for pipes provided with seal |
摘要 |
A threaded joint for pipes comprising at least one seal of the metal-metal interference type arranged externally to the female thread. The joint has an extension of the box beyond the seal which produces an elastic tightening band effect on the seal so that excessive interference on the seal is not necessary, thus favoring correct making up. |
