Heat Exchanger Tube as per SA213-TP304

Heat exchanger tube SA213-TP304 mean the tubes manufacture as per standard ASME SA213, in material grade TP304, which used in heat exchager as heat transfer elemets.

ASME SA213 TP304 is a grade that covers standard heat exchanger or high-pressure tubes that are designed with 304 austenitic stainless steel. The ASTM A213 TP304 Tube is designed with a superior composition consisting of chromium and nickel. This gives the tubes enhanced resistance against corrosive and oxidative media across an array of stress-induced environments.

ASTM A213/ASME SA213 is Standard Specification for Seamless Ferritic and Austenitic Alloy-Steel Boiler, Superheater, and Heat-Exchanger Tubes.

As per SA-213/SA-213M: All austenitic tubes shall be furnished in the heat-treated condition. It shall consist of heating the material to a minimum temperature of 1040℃ and quenching in water or other rapid cool.

The Heat exchanger tube SA213-TP304 surface shall not have defects such as scale, crack，bubble，overlap，fold and inclusion etc.

Heat exchanger tube SA213-TP304 Mechanical Properties

One tension tensile test shall be made on a specimens for on tube for lots of not more than 50 tubes, or on specimens form two tubes for lots more than 50 tubes.

One flattening test shall be made on specimens form each end of one finished tube, not the one used for the flaring test, from each lot.

One flaring test shall be made on specimens form each end of one finished tube, not the one used for the flattening test, from each lot.

Each tube shall be subjected to the nondestructive electric test or the hydrostatic test. The tests could refer to SA-1016/ SA-1016M
