Welded Tee FAQ Section
FAQ 1: What are the main advantages of using Welded Tee fittings?
Welded Tee fittings offer several significant advantages over other connection methods. They provide superior strength and leak-proof performance in high-pressure systems. The welded construction eliminates potential leak points found in threaded or flanged connections. Welded Tees maintain full-bore flow characteristics with minimal turbulence, making them ideal for critical applications in oil & gas, chemical processing, and power generation industries. Additionally, they require less maintenance over time compared to mechanical joining methods.
FAQ 2: How do I select the right Welded Tee for my application?
Selecting the appropriate Welded Tee involves considering several factors. First, determine the material compatibility with your process media - consider corrosion resistance and temperature requirements. Next, match the pressure rating (class) to your system's operating conditions. Ensure the dimensional specifications (size and wall thickness) align with your existing piping. For specialized applications, consider additional requirements like impact testing, NACE MR0175 compliance for sour service, or enhanced radiography examination. Our technical team can assist with material selection and specification verification.
Comparison of Welded Tee Types
| Type | Features | Applications |
|---|---|---|
| Equal Tee | All three openings same size | General flow division applications |
| Reducing Tee | Branch smaller than run | Connecting smaller lines to main headers |
| Barred Tee | Internal bar across main run | Pigging operations in pipelines |
| Reinforced Tee | Additional reinforcement at branch | High stress applications |
FAQ 3: What quality certifications are available for Welded Tee products?
Our Welded Tee fittings come with comprehensive quality documentation including Material Test Reports (MTRs) that verify chemical composition and mechanical properties. We offer products certified to various international standards such as PED 2014/68/EU for European markets, ASME B16.9 for North American applications, and GOST certification for CIS countries. Additional certifications available include NACE MR0175/ISO 15156 for sour service, NORSOK M-630 for offshore applications, and various client-specific approvals. All products undergo rigorous testing including hydrostatic testing, dimensional verification, and visual inspection to ensure compliance with specification requirements.
Surface Treatment Options for Welded Tee
- Sandblasting (SA 2.5 or SA 3 finish available)
- Galvanizing (hot-dip or electroplated)
- Passivation for stainless steel products
- Painting (epoxy, FBE, or client-specified coatings)
- PE/PP wrapping for corrosion protection
Applications of Welded Tee Fittings

Welded Tee Installation Guidelines
Proper installation ensures optimal performance of Welded Tee fittings:
- Verify material compatibility and specification before installation
- Ensure proper alignment with existing piping (check run and branch orientations)
- Use appropriate welding procedures (WPS/PQR) qualified for the material
- For critical services, consider pre-heat and post-weld heat treatment
- Implement proper weld inspection methods (VT, PT, RT as required)
- Pressure test the completed system according to applicable codes
