Application:
High pressure, low & medium pressure boiler steel pipestubes
are suitable for making
super-heaters, re-heaters, water wall, and economizer in
large-scale power plant.
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.
Hydrostatic or Nondestructive Electric Test – 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.
Materials and Manufacture:
The Steel shall be killed.
The Tubes shall be made by the seamless process and shall be either
hot-finished or cold finished, as specified.
Heat Treatment – Ferritic Alloy and Ferritic Stainless Steels – The
ferritic alloy and ferritic stainless steels shall be reheated for
heat treatment in accordance with the requirements of Standard.
Heat treatment shall be carried out separately and in addition to
heating for hot forming.
