Abstract
This patent document discloses an improved series of nozzles and completion plugs for use in installing linestops in pressurized pipes. The improved nozzles are capable of accommodating two different types of completion plugs, including a threaded completion plug and a push-in type completion plug that is held in place within the nozzle by pins that extend through a flange of the nozzle. Lower edges of the nozzles are designed to facilitate the welding of the nozzle to an upper clamp or upper saddle member. Specifically, the lower or proximal beveled edge includes an inner lip that acts as a dam to prevent seepage of welding material between the proximal edge of the nozzle and the upper saddle member during the welding of the former to the latter.
