A213 Heat Exchanger Tube

A213 heat exchanger tube are widely used for heat system in many industries, there are many grades to select for seamless tubes as ASTM A213, grades contain 304/304L, 316/316L and other stainless steels, excellent performance in heating and high pressure environments.

Tube heat exchanger require high quality stainless steel tubes to meet harsh environment, excellent expanding and clear surface are important to install tubes for heat exchanger, straighten tubes and U bend tubes are available as ASTM A213 / SA213.
