The
term
nominal
wall

has
been
assigned
for
the
purpose
of
convenient
designation,
existing

as
given
in
ASME
B36.10.
It
shall
be
permissible
to
furnish
pipe
having
other

provided
such
pipe
complies
with
all
other
requirements
of
this
specification.
Pipe
ordered
under
this
specification
shall
be
suitable
for
bending,
flanging,
and
similar
forming
operations,
and
for
welding.
When
the
steel
is

it
is
presupposed
that
a
welding
procedure
suitable
to
the
grade
of
steel and intended use or service will be utilized.
Note 1:
It is suggested, consideration be given to possible graphitization.
Note

:
The

has
been
substituted
in
this
standard
for
such

Supplementary
requirements
of
an
optional
nature
are
provided
for
seamless
pipe
intended
for
use
in
applications
where
a

pipe
is
required.
These
supplementary
requirements
call
for
additional
tests
to
be
made
and
when
desired
shall
be
so
stated
in
the
order.1.3
The
values
stated
in
either
SI
units
or
inch-pound
units
are
to
be
regarded
separately
as
standard.
The
values
stated
in
each
system
may
not
be
exact
equivalents.
Therefore,
each
system
is
to
be
used
independently
of
the
other.1.4

To answer the question “Why Stainless Steel?
these and other beneficial properties of the Mo containing stainless
steels are summarized as follows:
Excellent
corrosion
resistance
-
SS
are
significantly
more
resistant
to
oxidation
by
water
and
biocides
than
carbon
steel
and
cast
or
ductile
iron. This results in longer life time for pipelines.
Corrosion
protection
–
an
internal
and
external
coating
is
not
required
for
SS,
nor
is
cathodic
protection.
This
reduces
system
cost
and
makes
stainless steels more compatible with environment.
Hygienic
materials
-
due
to
their
very
high
passive
film
stability,
SS
are
basically
inert
in
waters.
Leaching
of
alloying
elements
(Cr
and
Ni)
is
within
safe
limits.
As
a
result,
they
provide
a
better
quality
of
drinking
water.
