ASTM A350 LF2 Socket Weld Elbows and Branch Outlet Fittings Supplied to Turkey for Sour Service Applications
Haihao Group recently completed the production and shipment of a batch of ASTM A350 LF2 branch outlet fittings for sour service and socket weld elbows for a customer in Turkey. Manufactured in accordance with ASME B16.11 and MSS SP-97, these low-temperature carbon steel fittings are designed for demanding oil and gas pipeline systems operating in corrosive environments.
The order included socket weld elbows, socket weld branch outlet fittings, and butt weld branch outlet fittings produced from ASTM A350 LF2 Class 1 material. All products were supplied with heat treatment and controlled sulfur content below 0.025%, meeting stringent project specifications for sour service applications.
The shipment consisted of several types of forged and branch connection fittings used in pipeline distribution systems.
Why ASTM A350 LF2 Is Ideal for Low-Temperature Pipeline Systems
One of the key requirements of this project was the use of ASTM A350 LF2 branch outlet fittings for sour service. ASTM A350 LF2 is a low-temperature carbon steel material specifically developed for applications where impact toughness and reliability are essential.
Key advantages include:
- Excellent low-temperature toughness
- High resistance to brittle fracture
- Good weldability
- Stable mechanical properties
- Suitable for critical pipeline systems
Because of these benefits, ASTM A350 LF2 branch outlet fittings for sour service are widely used in LNG facilities, natural gas projects, offshore platforms, and refinery applications.

MSS SP 97 ASTM A350 LF2 branch outlet fittings and socket weld elbows for sour service
Designed for Sour Service Environments
The fittings supplied for this project were manufactured for sour service conditions and complied with NACE MR0175 requirements.
Sour service systems often contain hydrogen sulfide (H₂S), which can increase the risk of:
- Sulfide stress cracking
- Hydrogen-induced cracking
- Corrosion-related failures
To improve performance in these environments, the fittings were produced using carefully controlled materials and heat treatment processes.
Additional project requirements included:
- Full heat treatment
- Sulfur content below 0.025%
- Material traceability
- Dimensional inspection
- Compliance with NACE requirements
These measures help ensure long-term reliability in challenging operating conditions.
Branch Outlet Fittings for Efficient Pipeline Connections
Branch outlet fittings play an important role in modern piping systems by providing a reinforced connection between the main pipeline and branch line.
Compared with fabricated branch connections, MSS SP-97 branch outlet fittings offer:
- Improved structural strength
- Reduced stress concentration
- Better flow characteristics
- Faster installation
- Enhanced safety and reliability
For this project, both socket weld and butt weld branch outlet fittings were supplied to accommodate different piping configurations.
Quality Assurance Throughout Production
Haihao Group applies strict quality control procedures to every order.
The supplied ASTM A350 LF2 branch outlet fittings for sour service underwent:
Inspection Procedures
- Raw material verification
- Chemical composition testing
- Dimensional inspection
- Heat treatment verification
- Surface examination
- Marking inspection
- Final packing inspection
Each fitting was checked to ensure full compliance with customer specifications before shipment.
Applications of ASTM A350 LF2 Branch Outlet Fittings
These products are commonly used in:
Oil and Gas Pipelines
Reliable branch connections for transmission and gathering systems.
LNG Facilities
