Barred Tee Manufacturers for Critical Pipeline Applications
In modern oil & gas and energy infrastructures, maintaining pipeline integrity during pigging operations is critical. Barred tees prevent the pig from entering branch lines, ensuring continuous flow and operational safety.
Not all manufacturers can guarantee mechanical integrity, custom geometry, and full code compliance under extreme pressure and temperature. Failures often arise from improper welding, lack of FEA validation, or substandard materials.
M.E.G.A. S.p.A. stands among the leading barred tee manufacturers, offering engineered fittings produced entirely in-house — from forging to final inspection — and compliant with the world’s most demanding industry standards.
Why choose M.E.G.A. for barred tee manufacturing
1. Certified design and engineering excellence
All M.E.G.A. barred tee fittings are designed according to:
- ASME B31.3, ASME BPVC Section VIII Div. 1 & 2
- DNV OS-F101 for subsea pipelines
- MSS SP-97, EN 13480-3, and other applicable codes
Design validation includes Finite Element Analysis (FEA) to simulate stress loads, ensuring safety under cyclic fatigue and flow-induced vibration (FIV).
2. Full In-House Production Capability
M.E.G.A.’s vertically integrated process covers:
- Closed-die forging up to 6 inches and machining up to 80 inches
- Heat treatment and mechanical finishing
- Non-destructive testing (PT, UT, MT, RX) in its Accredia 17025-certified laboratory
- Hydrostatic testing and complete documentation package
This internal control guarantees consistent quality and full traceability for every fitting.
3. Material flexibility and weld overlay solutions
Barred tees are available in:
- Carbon, Low-Temp Carbon, and Cr-Mo Steels
- Stainless Steels, Duplex & Super Duplex, SMO F44
- Nickel Alloys (Inconel 625®, Hastelloy C276®)
When required, internal surfaces can be protected using weld overlay cladding with corrosion-resistant alloys to extend service life in subsea or corrosive environments.
Technical overview – what defines a barred tee
Function and design
A barred tee is a T-shaped forged fitting with restriction bars welded internally to prevent a pig from entering a branch connection during cleaning or inspection operations.
Key technical features:
- Bars are flush with the internal pipe diameter, ensuring smooth pig passage
- Constructed from the same or compatible alloy as the main pipeline
- Available in equal or reducing configurations, designed for minimal flow restriction
Typical applications
M.E.G.A. barred tees are engineered for:
- Piggable subsea pipelines
- Offshore manifolds and riser systems
- High-pressure onshore lines
- LNG and petrochemical facilities
- Hydrogen and carbon-capture projects
