A672 Pipe Introduction
ASTM A672 carbon steel EFW pipe is a carbon steel pipe produced in accordance with the ASTM A672 standard and manufactured using the electric arc welding (EFW) process. It is designed specifically for the transportation of high-pressure fluids and gases and is widely used in pipeline systems in the oil, natural gas, and chemical industries.
A672 Pipe Advantages
High Strength
ASTM A672 carbon steel EFW pipe boasts a tensile strength exceeding 70,000 psi, making it suitable for high-pressure pipelines such as those used in oil and natural gas transmission, ensuring it will not rupture or deform under high pressure.
Arc Welding Process
The longitudinal weld of the ASTM A672 carbon steel EFW pipe is produced using electric fusion welding, where the high-temperature arc melts the welding material, allowing the joint to fuse firmly with the pipe's metal structure, making it less prone to cracks at the weld.
High Dimensional Precision
ASTM A672 pipes have strictly controlled dimensional tolerances, with outer diameter tolerances within ±0.5 mm and wall thickness tolerances within ±10%, ensuring the pipes fit perfectly with other equipment during installation.
A672 Pipe Standards and Specifications
ASTM A672, Standard Specification for Electric-Fusion-Welded Steel Pipe for High-Pressure Service at Moderate Temperatures. Grades shall designate the type of plate used while class shall designate the type of heat treatment performed during pipe manufacture. Class shall be designated as to whether the weld is radiographically examined, and as to whether the pipe is pressure tested.
