Standards: ASTM A213, ASME SA213, ASTM B163, ASME SB163, EN10216-5, JIS G3463, DIN17458

Specification: OD 6mm to 1016mm; WT 0.5mm to 30mm; Length Max 25m.

Tests: all tubes should be hydro static tested, non-destructive tested (ET and/or UT).

The mechanical properties of part materials are as following. And other materials would be listed in other products’ introduction.

Hardness Requirements:

The material shall conform to the hardness requirements given in Table 4. Brinell, Vickers, or Rockwell hardness
tests shall be made on specimens from two tubes from each lot.

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

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

Mechanical property requirements do not apply to tubing smaller than 1⁄8 in. [3.2 mm] in inside diameter or thinner than 0.015 in. [0.4 mm] in thickness.

Each tube shall be subjected to the nondestructive electric test or the hydrostatic test. The type of test to be used shall be at the option of the manufacturer, unless otherwise specified in the purchase order.

Tubes, when inserted in a boiler or tube sheet, shall stand expanding and beading without showing cracks or flaws. Superheater tubes when properly manipulated shall stand all forging, welding, and bending operations necessary for application without developing defects.
