Haihao Group is proud to announce the successful production and shipment of an additional batch of ASME B16.11 45° socket weld elbows, manufactured from ASTM A350 GR. LF2 CL1 material, for a valued customer in Singapore.
This supplementary order includes 35 pieces, which have been completed with strict adherence to international standards and customer-specific material requirements.
Product Details
Product Type: 45° Socket Weld Elbow
Size: 1 inch
Standard: ASME B16.11
Material: ASTM A350 Grade LF2 Class 1
Pressure Class: 6000#
Additional Quantity: 35 pieces 
Material Requirements: Sulfur and Phosphorus Control
For this project, the chemical composition of ASTM A350 GR. LF2 CL1 material was specifically controlled to meet stringent requirements:
Sulfur (S) content less than 0.01%
Phosphorus (P) content less than 0.03%
Controlling the sulfur and phosphorus content is crucial to enhance the toughness, improve weldability, and minimize the risk of brittle fracture at low temperatures. This ensures the elbows are ideal for critical applications such as oil and gas pipelines, offshore structures, and other low-temperature service environments.
