Plymouth Tube
Company Trent
SANI-FLOW®
is the ideal
stainless steel
tubing for the
hygienic services
industry
including: dairy, food and beverage, pharmaceutical, and bio-tech. SANI-FLOW® is
welded stainless
steel tubing
made from
316(L), UNS #
S31603, which is
mechanically
polished and
passivated
before being
packed, in order
to maintain the
interior finish. SANI-FLOW®
is manufactured
in accordance
with ASTM A249,
SA249, A269, and
A270-S2 as well
as additional
restrictions and
criteria as
outline in
internal
Plymouth Tube
specifications.
Manufacturing
Process SANI-FLOW®
mechanically
polished
tubing is made
from cold rolled
2B stainless
steel strip
whose chemical
elements are
specifically
controlled to
enhance
weldability.
Manufacturing
includes a
Tungsten Insert
Gas (TIG or
GTAW) method of
welding. The
weld bead is
then cold worked
to full finished
condition. The
internal surface
of the tubing is
longitudinally
belt polished
and then
mechanically
polished
to a 15 microinch Ra or
smoother. The
external surface
of the tubing is
then
mechanically
polished via
Plymouth Tube's
state-of-the-art
process. After
polishing, each
tube is cleaned
by a nitric acid
passivation and
then a deionized
water rinse,
then dried with
filtered
compressed air.

Testing
Plymouth Tube
Co's Trent Mill
maintains
rigorous quality
control
inspection and
testing
procedures to
ensure all high
purity
processing
requirements are
met and
maintained.
Tubing must be
capable of
passing the
flatten, flange,
and reverse bend
requirements of
ASTM A1016. Each
length is also
eddy current
rested to the
requirements of
ASTM A1016.
Additional
inspection and
testing such as
auger, SEM,
ultrasonic,
ESCA,
borescoping,
liquid penetrant,
and corrosion
resistance
inspections are
available when
specified.
