ASTM A106 Vs A53

A53 tube and A106 tube
ASTM A53 is the standard specification for black and hot-dip, galvanized, welded, and seamless pipe.
ASTM A106 is the standard specification for seamless carbon steel pipe for high temperature applications.
A53 pipe vs. A106 pipe – pipe application types
A53 can be welded or seamless, depending on the circumstances of purchase. It is a general steel pipe specification covering galvanized pipes and black pipes. A106 is a chemically similar pipe but suitable for high temperature applications (up to 750 degrees Fahrenheit). It is a seamless tube.
A53 tube and A106 tube – chemical composition
When we compared A106-B and A53-B Seamless pipe from a chemical composition perspective, we found: A106-B contains the least silicon. 0.10%, of which A53-B is 0%. Silicon is an important element in improving heat resistance standards. A106-B contains 0.29-1.06% manganese, of which A53-B contains 1.2% manganese. A106-B has low sulfur and phosphorus content, with a maximum content of 0.035%, of which A53-B contains 0.05% and 0.045% respectively.
