摘要:
Embodiments of a polyethylene (“PE”) pipe servicing system of this disclosure may include a fusible PE fitting (F) providing a branch connection to a PE pipeline section or run (P), a valve (10) connected to the fitting and including quick connect/disconnect means, and a machine connectable to the valve including complementary quick connect/disconnect means. The quick connect means provide for full scope of operation, including cleaning, fusion, cool down, hot tap, plugging, and completion. No squeezing is used. The quick connect/disconnect means may include a first portion 20 of a cam profile and a second portion 40 of the cam profile complementary to that of the first. The machine may be a drilling or hot tapping machine (30T), a plugging machine (30P), or a completion machine (30 C), and their associated tools. The valve and machine are more lightweight and faster and easier to use than the prior art.
