Haihao Group is proud to announce the successful production and delivery of ASME B16.11 45° socket weld elbows made from ASTM A350 Grade LF2 Class 1 material for our valued customer in Singapore. These high-quality fittings are specifically designed for use in low-temperature service applications where toughness and reliability are critical.

ASME B16.11 ASTM A350 GR. LF2 CL1 45° socket weld elbows
The ASME B16.11 standard governs forged fittings, including socket weld elbows, ensuring strict dimensional tolerances, material properties, and pressure ratings. Our 45° socket weld elbows allow for a smooth directional change in piping systems with a strong, leak-proof welded joint, making them ideal for critical piping networks.
Material Specification:
The elbows are manufactured from ASTM A350 GR. LF2 CL1 carbon steel, a low-alloy material specially formulated to maintain mechanical properties at low temperatures. This ensures excellent notch toughness, resistance to brittle fracture, and durability under demanding service conditions.
Key Features:
Material Grade: ASTM A350 GR. LF2 CL1
Manufacturing Standard: ASME B16.11
Connection Type: Socket Weld
Angle: 45 Degrees
Application: Low-temperature pressure systems in industries such as oil & gas, petrochemical, and power generation.

Quality inspection of ASME B16.11 ASTM A350 GR. LF2 CL1 45° socket weld elbows
Quality Control and Inspection:
To guarantee the precision and quality of each fitting, Haihao Group conducts comprehensive inspections. As shown in the photos, our team carefully measures critical dimensions using professional instruments like vernier calipers, ensuring all fittings meet ASME B16.11 tolerances and customer specifications. Each elbow undergoes:
- Visual Inspection
- Dimensional Verification
- Material Traceability
- Marking Check
The surface of each fitting is clearly marked with essential information such as material grade and heat number, providing full traceability back to the material source.
At Haihao Group, we are committed to delivering products that exceed customer expectations. The 45° socket weld elbows provided to our Singaporean client demonstrate our ability to meet strict technical requirements, offer timely delivery, and maintain top-tier manufacturing quality.
