Filiz Steel, a reputable supplier located in Istanbul, Turkey, proudly provides high-quality **Carbon Steel ASTM A671 Grade CC65 Pipes** designed for **high-pressure and low-temperature applications** in critical industrial settings. The ASTM A671 Grade CC65 specification covers **electric-fusion-welded (EFW) carbon steel pipes**, crafted from pressure vessel quality plates that boast **intermediate tensile strength** and are primarily intended for **atmospheric and lower-temperature environments**. These pipes are recognized for their **toughness, weld integrity, and reliable mechanical performance**, even in challenging service conditions.
The A671 Gr CC65 pipes are made from carbon steel plates that generally meet the standards of **ASTM A516 Grade 65**, providing a **minimum tensile strength of 485 MPa** and a **yield strength of 260 MPa**. They are **welded using fusion welding techniques**, followed by heat treatment and non-destructive testing to guarantee structural integrity. For critical applications, optional supplementary requirements such as **impact testing, ultrasonic examination, and hydrostatic testing** can be provided. The pipes come in a variety of diameters and wall thicknesses, with ends available in **beveled, plain, or threaded forms**.
