Differences of ASTM A213 And ASTM A269

Standard	ASTM A213	ASTM A269
Basic Difference	Seamless Steel Tubing	Welded and Seamless Steel Tubing
Wall Thickness	Mostly minimum wall thickness (0, +20%), also accept average wall thickness (+/-10%)	Average wall thickness (+/-10%)
Applications	Heat exchangers and Superheaters to maintain the transmission temperature of the different substances.	Performs well in corrosion resistance and oxidation resistance required in elevated temperature.
