Thin-walled pipe joint
Abstract:
Thin-walled pipe joints can include a first pipe and a second pipe. The first pipe includes a hollow pin member positioned at about an end of the first pipe. The second pipe includes a hollow box member positioned at about an end of the second pipe. The hollow box member is further configured to at least partially surround the pin member of the first pipe. The joint also includes a first ring placed adjacent an end of the hollow pin member and a second ring engaged with the box member. The second ring substantially axially abuts against the first ring and the first ring substantially axially abuts the box member. The second ring further generally extends from the first ring in a direction opposite to the end of the pin member adjacent to the box member.
