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 (30C), and their associated tools. The valve and machine are more lightweight and faster and easier to use than the prior art.

Disclosed is a fluid diverting device which comprises a saddle unit, a water dividing unit and a leakproof tube unit. The saddle unit includes a saddle body, a water inlet through hole and a main pipe accommodating portion. The water dividing unit includes a water dividing main portion, an inlet tube portion and an outlet tube portion. The inlet tube portion is inserted into the water inlet through hole. A screw thread is provided on an external tube wall of the inlet tube portion or on an internal tube wall of the inlet tube portion. The leakproof tube unit includes a sleeve portion, a connecting portion and a leakproof pad. The connecting portion is provided on one end of the sleeve portion and the leakproof pad is in tight contact with the connecting portion. A corresponding screw thread is provided on an external tube wall of the sleeve portion or on an internal tube wall of the sleeve portion. The sleeve portion is screwed with the inlet tube portion in a manner that the external tube wall of the sleeve portion is screwed with the internal tube wall of the inlet tube portion or the internal tube wall of the sleeve portion is screwed with the external tube wall of the inlet tube portion.
