METHOD OF FORMING METAL-TO-METAL SEAL Russian patent published in 2024 - IPC F16J15/08 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to a method of forming a metal-to-metal seal. Method of forming a metal-to-metal seal between two opposite metal surfaces using a metal sealing ring comprises a tubular metal housing and an inlet branch pipe extending from the housing for supplying internal pressure to the housing. Method comprises placing a metal sealing ring body between metal surfaces and using an inlet pipe to supply internal pressure to the body, to deform the housing relative to the metal surfaces to form a seal. Housing is plastically deformed so that the internal pressure in the housing can be removed without breaking the seal.

EFFECT: disclosed is a method of forming a metal-to-metal seal.
