FLOW TEE

Scrapper / Flow Tees

Techfield flow tees are specialized design that facilitates the passage of pipeline past tee connections where flow bypass often leaves pigs stranded.Flow Tees are used to ensure a safe passage to Pipeline Pigs across branch connection.

Unrestricted flow

  • The flow in the flow tees are unrestricted due to slots in internal sleeve and annular cavity.
  • The provide area of flow in slots are higher than the branch area to avoid any pressure buildup in flow tee cavity.
  • The fluid flow in normal operation is through a flow tee branch towards flow direction and through launcher/receiver trap during pigging operation.

Unrestricted pig passage

The flow tee internal sleeve are provided with same inner diameter as connecting line pipe. This feature of flow tee allows easily pig passage.
