MSS SP-97 A105 Outlet Fittings
MSS SP-97 A105 Outlet Fittings are ideal for high-pressure, high-temperature, non-corrosive systems in oil & gas, chemical, and power industries.
High Quality MSS SP-97 A105 Outlet Fittings
- Connection Types: Socket weld, buttweld, threaded.
- Pressure Ratings: Class 3000, 6000, 9000 (~750 psi, 1500 psi, 2250 psi).
- Reinforced Design: Forged construction provides extra thickness at the branch-to-header junction, eliminating the need for reinforcement pads

A105 Material Properties
- Composition: Carbon steel (C ≤0.35%), with minor manganese (Mn) and silicon (Si).
- Temperature Range: -29°C to +425°C (short-term up to +550°C).
- Advantages: High strength (tensile ≥485 MPa), oxidation resistance at high temperatures, and machinability.
Typical Applications
- Oil & Gas: Wellhead equipment, pipeline branch connections.
- Chemical Industry: Reactor and heat exchanger inlet/outlet branches.
- Power Systems: Boiler feedwater lines, steam trap branches.
- Advantages: Eliminates the need for reinforcement pads on the main pipe, reducing leakage risks and installation time.

Selection and Installation Guidelines
Selection Criteria:
- Branch Size: Branch diameter should typically be ≤½ of the header diameter.
- Pressure Rating: Must match system design pressure (e.g., Class 3000 ≈ PN50).
- Media Compatibility: A105 is suitable for non-corrosive media (e.g., water, oil, steam); stainless steel (e.g., SS 316) is required for corrosive environments.
Installation Requirements:
Welding:
- Buttwelding must follow ASME B31.3 for full-penetration welds.
- Socket welding requires a 1.6mm root gap.
Inspection: Visual testing (VT), liquid penetrant testing (PT), or radiographic testing (RT).
Comparison with Other Standards
| Parameter | MSS SP-97 A105 | ASME B16.11 | MSS SP-75 |
| Scope | Reinforced branch outlets | Socket weld/threaded fittings (general) | Buttweld branch fittings (non-reinforced) |
| Material | Forged carbon steel (A105) | Forged steel/stainless steel | Cast steel/stainless steel |
| Pressure Rating | Up to Class 9000 | Up to Class 6000 | Up to Class 300 |
| Applications | High-pressure/temperature systems | Medium/low-pressure systems | Low-pressure non-critical systems |
FAQ
- No. A105 is not resistant to H₂S or strong acids. Use stainless steel (e.g., F316) or nickel alloys instead.
MSS SP-97 fittings are integrally reinforced; no additional reinforcement pads are needed.
MSS SP-97 A105 Outlet Fittings are ideal for high-pressure, high-temperature, non-corrosive systems in oil & gas, chemical, and power industries. Their integrally reinforced design simplifies installation and enhances reliability, but material limitations for corrosive media must be considered. Selection should account for system pressure, temperature, and media properties—consult an engineer for critical applications.
