What is a split tee fitting?
It is a pipeline fitting designed such that the inner diameter of the fitting is the same size as the outside diameter of the pipe that will be hot tapped. As a rule of thumb, a split tee is used when the branch connection is equal to or greater than half the diameter of the run direction.
What is a hot tap fitting?
The hot tap procedure involves attaching a branch connection and valve on the outside of an operating pipeline, and then cutting out the pipe-line wall within the branch and removing the wall section through the valve. Hot tapping avoids product loss, methane emissions, and disruption of service to customers.
What is a tapping tee used for?
The tap tee saves time and money for contractors. By using a hole saw to drill into the side wall of the main line of the pipe. A push and turn method is used to lock the tap tee in place. The contractor no longer has to worry about tap tees popping out once the SPI fitting is locked in place.
What is the advantage of hot tapping?
Hot tapping is a process that allows pipeline repairs or expansion to be completed without disrupting normal operations or depressurizing the system. The benefit of hot tapping is that sections of pipeline can be isolated and flow can be stopped with minimal downtime and without stopping production.
What does 10th tee mean in golf?
“Split tees” is a term that applies to the way some golf tournaments schedule golfers to tee off: When split tees are in use, groups of golfers start their rounds from both the No. 1 and No. 10 tees, simultaneously.

- Grab the two pieces and lay them on top of each other (graphic to graphic).
What is hot tapping and plugging?
Hot tapping and plugging (HT&P) creates safe work zones during pipeline maintenance and pipeline repair, without the time, risk or expense of shutting down the pipeline system. There’s no decommissioning, depressurization or significant impact on product flow.
Can you hot tap same size pipe?
Welding of Hot Tap Fitting The size of set-on branch shall be at least one pipe diameter smaller than the diameter of the run pipe. Full size hot tap connections are not recommended as there is a possibility for the hot tap cutter to cut into the run pipe.
What is hot tapping and line stopping?
A controlled method to isolate a section of pipeline through inserting a line stop plug into the pipeline while the system continues to operate normally allowing repairs and/or maintenance of critical components downstream.
What is hot tapping hazards?
Skin/eye burns, and electric shock are potential direct hazards. A hot surface or a spark can burn skin, either by contact or from radiated heat. The eyes are particularly sensitive to burning, including from light radiation – “arc eye”.
What can be installed into a line to stop the flow of hazardous materials?
Line Stops can be performed on almost any kind of pipe with pressures or product under pressure. The Line Stop operation consists of a special flanged Line Stop fitting, a temporary valve, and our actuator. The Line Stop fitting is installed and tested, the temporary valve is installed, and the hot tap is completed.
Why do some golfers start on the 10th hole?
TWO-TEE START (TANDEM START) This is when a tournament begins with competitors starting their rounds on the tenth hole as well as the first hole. It is used to squeeze competitors onto the course when there is concern about fitting in a large field with a limited amount of daylight.
What are the sizes of split tee fittings?

Can I Weld a split tee pipe?
If so, a split tee is unacceptable. The heat from welding can cause the coating to flake off and any protections made by the coatings will no longer be valid. During the hot tap process, the tool will damage the coating or cement lining. This, too, will remove the ability for coating to protect the pipe at the hot tap.
