Product information

Stainless Steel 347/ 347H TEE

TEE is a forged fitting used for splitting and changing flow direction of run pipe of 90° deg.
It is available in two categories:
EQUAL TEE is used if header and branch pipe have the same size
REDUCED TEE is used if header and branch pipe have the different size
Stainless Steel TEE can be manufactured with butt-weld extremities, socket extremities or threaded extremities.
Dimensions of Stainless Steel TEE can be in accordance with ASME B16.9, MSS SP-75.
Stainless Steel TEE can be manufactured on customer’s request with a special design.
