ASTM A671 CC65 Pipes

ASTM A671 CC65 Pipes are engineered for high-pressure and low-to-moderate temperature applications where superior mechanical strength and structural reliability are required. Manufactured from electric-fusion-welded (EFW) carbon steel plates, these pipes are extensively used in oil & gas, petrochemical, power generation, and heavy engineering industries.

What are ASTM A671 CC65 Pipes?

ASTM A671 is a specification that covers electric-fusion-welded steel pipes designed for pressure service at atmospheric and lower temperatures. The CC65 grade offers higher tensile strength compared to CC60, making it suitable for more demanding pressure and structural applications.

Key Features of ASTM A671 CC65 Pipes

Higher tensile strength than CC60 grade
Excellent pressure-handling capability
Uniform wall thickness and superior weld integrity
Good impact resistance at lower temperatures
Long service life with consistent performance

Chemical Composition (Typical)

Carbon (C): Max 0.30%
Manganese (Mn): 0.29 – 1.06%
Phosphorus (P): Max 0.035%
Sulfur (S): Max 0.035%
Silicon (Si): Max 0.40%
