Sphere and Bar Tees
Sphere and Bar Tees are utilized in a pig launcher/receiver system and/or at branches in the pipeline to ensure the safe passage of a pig or sphere past the open branch area.
To compliment our range of pigs and spheres pipeline engineering has the in-house engineering, manufacturing and testing capacity to produce piggable Pipeline Sphere and Bar Tees.
Piggable Bar Tees incorporate simple bar sections welded across the pipeline tee branch to allow a pig to negotiate the branch opening. Piggable Sphere Tees are more complex and involve a slotted liner tube encased in an oversize jacket tee, such an arrangement ensures the sphere remains in the pipeline and does not traverse into the branch pipe.
Piggable Tees are manufactured to specific customer project specifications and International Pressure Vessel and Piping Codes (ASME, PD5500 etc). Our capacity ranges from 2” NS to 54” NS, ANSI Ratings 150 to 2500 and API, using carbon, stainless and alloy steel materials.
Piggable Tee contracts are managed by our in-house Pressure Vessel Business Unit dedicated solely to the purpose of engineering, manufacturing and testing this type of equipment and Pig Launcher/Receiver Vessels. With over 15 years experience in this particular field the Business Unit Engineers have particular expertise in supplying Tees for Sour Service environments, which require NACE and Corrosion Tested (HIC/SSCC) materials.
