TEES PRODUCT OVERVIEW
High-integrity flow-branching solutions engineered to ensure structural continuity and reliable performance across process piping systems and high-pressure transmission networks.
1. PRODUCT RANGE
Standard & Specialty Branch Fittings
• Equal & Reducing Tees
Manufactured via advanced hydraulic cold forming or heavy-duty forging processes, ensuring uniform grain flow and high mechanical strength at critical stress concentration zones.
• Barred Tees
Designed for piggable pipeline systems, featuring internal guide bars precisely welded into the branch outlet, allowing safe passage of pipeline pigs without disrupting flow efficiency.
• Split Tees
Reinforced branch fittings engineered for hot-tapping applications, enabling safe pipeline branching under live, pressurized operating conditions without system shutdown.
• Lateral & Angled Tees
Designed for specialized pipeline configurations where fluid direction must be introduced at controlled angles to minimize turbulence, erosion, and pressure loss.
DIMENSIONAL CONFIGURATIONS
Size Range: 1/2″ to 60″ NPS, with capability for larger custom-engineered diameters.
Wall Thickness: Schedule 10S to XXS, including heavy-wall custom designs based on project design pressure requirements.
METALLURGY & MATERIAL SPECIFICATIONS
• Carbon Steel
ASTM A234 WPB / WPC for general process piping systems.
• Low-Temperature Carbon Steel
ASTM A420 WPL6 certified for cryogenic and sub-zero temperature service.
• High-Yield Pipeline Steel
MSS SP-75 WPHY 42 to WPHY 70 for high-pressure oil & gas transmission pipelines.
• Stainless & Alloy Steel
ASTM A403 WP304/L, WP316/L; ASTM A234 WP11, WP22, WP91 for high-temperature and corrosion-resistant applications.
2. MANUFACTURING & QUALITY CONTROLS
Stress Engineering & Finite Element Analysis (FEA)
For critical branch fittings subjected to complex mechanical and pressure loads, detailed engineering validation is performed in compliance with ASME B31.3 and ASME B31.8 codes.
Finite Element Analysis (FEA) is used to simulate stress distribution, hydrodynamic forces, and structural integrity, ensuring safe performance under extreme operating conditions.
Hydrostatic Proof Testing
- 100% of custom-fabricated tees and critical service components undergo hydrostatic pressure testing in accordance with ASME B16.9 and project specifications.
- Testing ensures full pressure containment capability and confirms structural integrity under maximum allowable operating conditions.
Global Supply Chain Auditing & Quality Assurance
- Sourcing Integrity: Raw materials including plates, billets, and forged bars are sourced exclusively from globally approved mills in Europe, Japan, and South Korea.
- Material Certification: Full traceability provided in compliance with EN 10204 Type 3.1 and 3.2 certification standards.
- Third-Party Inspection: All manufacturing stages, heat treatment processes, and NDT examinations (RT, UT, MT, PT) are independently verified by leading inspection bodies including DNV, Bureau Veritas, and Lloyd’s Register.
