Application:
For high-temperature services that up to 750°F, A106 could substitute ASTM A53 pipe in most of the cases. In some countries, usually, ASTM A53 is for welded pipe while ASTM A106 is for seamless pipe. And if the client asked for ASTM A53 they will also offer A106. We will offer the pipe that complies with three standards ASTM A53 B / ASTM A106 B / API 5L B.
