  • Pipe connection structure
    Patent number: 5863081
    Abstract: An oil strainer head is attached to an oil suction pipe using a machined bulge flange in the pipe. A connection flange on the oil strainer head is fitted over the lower end of the pipe below the bulge flange. The bulge flange is then crimped in an outward curve to deform the connection flange into a corresponding outward curve captured within the crimped lower end. This structure eliminates the need for reinforcement and welding and produces a strong, non-leaking joint that reduces the number of parts and manufacturing operations.
