What is ASTM A672 steel pipe?
The ASTM A672 specification covers electrofusion welded (EFW) carbon steel pipe manufactured from pressure vessel grade steel plates, suitable for medium- and high-temperature environments.
What environments are ASTM A672 steel pipes suitable for?
ASTM A672 steel pipes are suitable for medium- and high-pressure, medium- and high-temperature environments in industries such as oil and gas, power plants, and chemicals.
Why does ASTM A672 steel pipe perform best in high-pressure applications?
The high yield strength and tensile strength of ASTM A672 steel pipes stem from the pressure vessel grade steel plates they use. Compared to seamless steel pipes such as ASTM A106, the ASTM A672 EFW process allows for thicker walls and more consistent weld quality. This ensures excellent load-bearing capacity and long-term reliability.
How does ASTM A672 steel pipe ensure long-term reliability?
To ensure structural integrity and safety, the ASTM A672 standard requires that internal and surface defects be inspected using various non-destructive testing (NDT) methods before pipes are put into service.
How to Prevent Defects in ASTM A672 Steel Pipe Manufacturing
Maintaining manufacturing precision is also crucial for ensuring defect-free pipes. To prevent defects in ASTM A672 steel pipe manufacturing, manufacturers must combine rigorous raw material inspection, process control, and stringent quality testing, including non-destructive testing (NDT), dimensional inspection, and pressure testing.
