ASTM A671 is a specification for electric fusion welded (EFW) carbon steel pipes with added filler metal. These pipes are made from pressure-grade plates, and are ideal for both atmospheric and low-temperature service. The ASTM A671 pipe range has grades like as A671 CC60, CC65 and CC70, which are known for their reliability to pressure, strength, and durability. The A671 pipe material includes 0.24% Carbon, 0.13% to 0.45% Silicon and 0.79% to 1.30% Manganese, which enhance its mechanical properties. The ASTM A671 pipe has a tensile strength of 450 MPa to 585 MPa and a yield strength of about 240 MPa. Each grade is tested for quality through hydrostatic, ultrasonic, and other non-destructive tests to ensure strength and reliability.
Multi Metals India is a trusted ASTM A671 pipe supplier that meets strict mechanical standards. These pipes are used in oil and gas, shipbuilding, fertilizers, and structural fabrication. It has coatings like FBE, PE, and black oil paint that are applied to prevent corrosion. Pipe ends come in bevelled, plain, or threaded finishes to suit different project needs. A671 CC65 pipe material is built for critical applications where pressure handling and toughness are required. These pipes offer a solid solution for transporting fluids and gases securely.

Application of ASTM A671 EFW Pipes
| ● Cryogenic services: such as liquefied natural gas (LNG) handling and transportation systems, require tubes capable of maintaining good mechanical properties at very low ambient temperatures. |
| ● City gas supply systems: In these systems, pipelines may need to operate at low winter temperatures, so specific grades of steel pipe are required to ensure safety and efficiency. |
| ● Chemical processing facilities: In chemical processing and cooling systems, certain fluids are handled at very low temperatures, requiring the use of ASTM A671 pipe to prevent pipe rupture due to brittleness at low temperatures. |
| ● Offshore platforms and oil drilling facilities: These facilities are often located in cold waters, and the use of A671 pipe ensures reliability and durability in cold marine environments. |
