Q: What is carbon steel pipe?
A: Carbon steel pipe is a steel pipe mainly composed of iron and carbon, with a carbon content generally less than 2.11%, used widely in fluid transportation and structural applications.
Q: What are the main classifications of carbon steel pipe?
A: It can be classified by manufacturing process (seamless / ERW / LSAW), application (fluid pipe, boiler pipe, structural pipe), and steel grade (low, medium, high carbon steel).
Q: What is the difference between seamless pipe and welded pipe?
A: Seamless pipe has no weld seam, higher pressure resistance; welded pipe is formed by rolling and welding, lower cost and higher production efficiency.
Q: What are common ASTM standards for carbon steel pipe?
A: Common standards include ASTM A53, A106, A139, A252, A333, etc.
Q: What is ASTM A53 pipe used for?
A: ASTM A53 is used for general-purpose pressure piping, water, gas, steam, and structural applications.
