Abstract
Hot pipes are tempered in an oil bath contained in a tapered, covered pan; a flap is temporarily opened for feeding, but closed when oil vapor develops, to be sucked off without contaminating the environment. Pan and cover structure are supplemented to prevent uncontrolled escape of vapor during treatment. Different handling devices for pipes in the interior of the pan are described.
