We need seamless stainless steel pipe samples( 45meters to
100 meters in total length) right away to go with our manufacturing
process for product testing, detail information is as following:
If you have any of these following dimension pipes in hand (and
must fit our standard, please read it carefully) , you may contact us
right away as we will test it in our manufacturing process immediately
and from there to see if we have the potential to cooperate with each
other( you will get direct feedback from us within about three to
four weeks)

Dimension: 20mm x1 mm /20mmx1.5mm
Material: TP304 Stainless steel
Production standard: A 213/A 213M 07 and Designation:
A 1016/A 1016M 04a

We will require the Hydrostatic Test according to
ASTM A 1016/ A 1016M Section 26( please check out the standard
listed at the end of this message)

The completed pipe must be able to handle/endure at least
1600 PSI or 11 MPa

If you are a manufacture with sincere desire to team up your capability
with our demand for long term cooperation with acknowledgment and
execution of following four key points throughout operation:
Please contact us immediately.
We are filtering our current list of suppliers for better choices,
let us know you are there as we like to go a long way with a
honest partner.
Serious inquiry Only.
Sincerely Yours

26. Hydrostatic Test
26.1 In lieu of nondestructive electric examination, and
when specified by the purchaser, and, except as provided in
26.2 and 26.3, each tube shall be tested by the manufacturer to
a minimum hydrostatic test pressure determined by the following
equation:
Inch2Pound Units: P 5 32000 t/D (3)
SI Units: P 5 220.6 t/D
where:
P = hydrostatic test pressure, psi or MPa,
t = specified wall thickness, in. or mm, and
D = specified outside diameter, in. or mm.
26.1.1 The hydrostatic test pressure determined by Equation 3
shall be rounded to the nearest 50 psi [0.5 MPa] for pressure
below 1000 psi [7 MPa], and to the nearest 100 psi [1 MPa]for
pressures 1000 psi [7 MPa] and above. The hydrostatic test
may be performed prior to cutting to final length, or prior to
upsetting, swaging, expanding, bending or other forming
operations, or both.

26.2 Regardless of the determination made by Equation 3, the
minimum hydrostatic test pressure required to satisfy these
requirements need not exceed 1000 psi [7 MPa]. This does not
prohibit testing at higher pressures at manufacturers option or
as provided in 26.3.

26.3 With concurrence of the manufacturer, a minimum
hydrostatic test pressure in excess of the requirements of 26.2
or 26.1, or both, may be stated on the order. The tube wall
stress shall be determined by the following equation:
S 5 PD/2t (4)

where:
S = tube wall stress, psi or MPa, and all other symbols as
defined in 24.1.
26.4 The test pressure shall be held for a minimum of 5 s.
26.5 If any tube shows leaks during the hydrostatic test, it
shall be rejected.
26.6 The hydrostatic test may not be capable of testing the
end portion of the pipe. The lengths of pipe that cannot be
tested shall be determined by the manufacturer and, when
specified in the purchase order, reported to the purchaser.
