Engineered for Low-Temperature Applications

The ASTM A350 LF2 CL1 material offers excellent impact toughness and mechanical strength in cold environments. As Kazakhstan’s industrial projects often operate under low ambient temperatures, this grade is widely preferred for:

• Oil & gas transmission lines

• Petrochemical processing units

• High-pressure fluid distribution systems

• Mechanical connection reinforcement

The combination of LF2 material and MSS SP-97 dimensions ensures compatibility, durability and long-term reliability.

Quality Assurance and Surface Protection

To meet the client’s specification, all products were delivered with a protective painted coating, improving resistance to corrosion during shipping, storage and field installation.

Haihao Group follows stringent quality procedures, including:

• Dimensional inspection per MSS SP-97

• Material verification for LF2 CL1
