Hot Tapping Split Tee
Download PDF Catalogue

Namdaran Petrogas Industries manufactures the 6"-56” Split Tee with or without guide bars. These guide bars block the tapped hole, keeping the line piggable.
Natural gas transmission and distribution companies need to make new connections to pipeline many times a year to expand or modify their existing system. Historically, this has necessitated shutting down a portion of the system and purging the gas to the atmosphere to ensure a safe connection. This procedure, result in methane emissions, loss of product and sales, occasionally customer inconvenience, and costs associated with evacuating the existing piping system.
The Split Tee is an welded or extruded style. The fitting is furnished with a flange that is pressure rated to match ASME standard flanges. It is used with hot tapping and/or plugging machines to tap and temporarily plug the line for maintenance, without shutdown.
Namdaran Petrogas Industries is a leading company for split tee hot tapping systems, in Iran and no other manufacturer can claim a completion system that has proven so reliable
