Split tee plug device

A system for intervention in a pipe, comprising:

• a tee, comprising:
• a sleeve positioned around the pipe;
• and
• a branch portion extending outwardly from the sleeve, the branch portion comprising:
• a housing fluidly connected to the sleeve via a neck;
• and
• a flange connection provided at an end of the housing opposite from the neck;
• a plug in an interior of the housing;
• an O-ring between a side of the plug and an interior surface of the housing;
• a flow path network formed through a wall of the housing fluidly connecting an exterior of the housing to the interior of the housing, the flow path network comprising a grease injection port extending from an opening at the exterior of the housing into the wall;
• a pressure test point integrated into the wall of the housing, the pressure test point comprising:
• a pressure test port fluidly connecting the exterior of the housing to the interior of the housing;
• and
• a valve disposed within the pressure test port;
• and
• an interlocking mechanism extending between and interlocking the plug and the housing.

A method, comprising:

• installing a hot tap assembly around a pipe,
• wherein the hot tap assembly comprises a tee having a branch portion extending outwardly from a sleeve, and
• wherein the installing comprises connecting the sleeve around an outer surface of the pipe;
• locating a plug inside a housing in the branch portion of the tee;
• providing a seal between the plug and the housing via an O-ring in an annular groove formed around a side of the plug;
• securing the plug inside the housing via a locking pin extending through the housing and partially into the side of the plug;
• injecting a sealant around the plug via a grease injection port fluidly connected to the annular groove;
• and
• seal testing the seal between the plug and the housing, the seal testing comprising measuring a pressure change in an interior of the housing using a pressure test port extending from an exterior of the housing to the interior of the housing.
