  • JOINING METAL PIPES
    Publication number: 20100314865
    Abstract: A metal pipe 10 is joined to another metal component 12 by shrinking the outer component onto the external circumference of the pipe. The internal diameter b of the outer component is initially smaller than the external diameter a of the pipe, but the outer component is heated so that it expands to a diameter at which it will fit over the pipe. When the outer component is fitted over the pipe and the temperature of the outer component allowed to drop, it will contract onto the surface of the pipe to make a permanent strong joint between the two parts.
