Tee Types

Equal Tee (Straight Tee)

All three outlets are the same bore size. The run pipe and branch pipe are of equal diameter. Used where the full flow is split or combined at 90°.

  • ✓ ASME B16.9 — e.g. 4" × 4" × 4"
  • ✓ EN 10253 Type A & Type B
  • ✓ Full bore — no flow restriction
⊤↓

Reducing Tee

The branch outlet is smaller than the run pipe. Designated as Run × Run × Branch (e.g. 6" × 6" × 4"). Used for take-off to smaller sub-headers.

  • ✓ ASME B16.9 — all standard reducing combinations
  • ✓ EN 10253 Type A & Type B
  • Note: specify run size × branch size

EN 10253 Type B Tees — PED Category III–IV

Type B tees have heavier nominal wall, tighter tolerances, orbital-weld bevel, and mandatory EN 10204 3.1 MTR. Specify "EN 10253 Type B" explicitly in your RFQ if PED Category III–IV applies. Arshya is one of very few Indian manufacturers certified for Type B across all material families.
