Abstract

A method of sealing together in a gas pipeline, comprising the steps of connecting a valve conduit to an upstanding pipe that branches off a gas pipe and introducing a spray hose into the pipe through said valve conduit and spraying the interior of the pipe with a sealing product, in which the operations of the method are carried out under conditions in which the escape of gas is greatly reduced.
