ASTM A511 TP316 304 Thick Wall Seamless Stainless Steel Tube for
Mechanical
covers seamless stainless tubing foruse in mechanical applications
where corrosion-resistant orhigh-temperature strength is needed.
covers seamless cold-finished me-chanical tubing and seamless
hot-finis hed mech anical tubing insizes up to 123/4 in.[ 325 mm]
in outside nominal diameter (forround tubing) with wall thicknesses
as required.
Permissible Variations in Dimensions of Round Tubing
1)Diameter and Wall Thickness (Cold Finished)-
Variations in outside diameter and wall thickness shall notexceed the amounts prescribed in Table 5.
2)Diameter and Wall Thickness (Hot Finished)
Variations in outside diameter and wall thickness shall notexceed the amounts prescribed in Table 6.
3)Lengths (Cold Finished or Hot Finished) Mechanicaltubing is commonly furnished in mill lengths 5 ft [1.5 m] andover. When random lengths are ordered, tube lengths may varyby an amount up to 7 ft [2.1 m]. Definite cut lengths arefurnished, when specified, to the length tolerances shown inTable 5 or Table 6. For tubing ordered in multiple lengths, it iscommon practice to allow a definite amount over for eachmultiple for the purchaser s cutting operations. This amountdepends on the type of purchaser s cutting and varies withdiffering wall thickness. The cutting allowance should bespecified on the purchase order.
4)Straightness Tolerances (Cold Finished or HotFinished) The deviation from straightness shall not exceedthe amounts shown in Table 7 when measured with a 3-ft [1-m]straightedge and feeler gage. If determined by the dial indicatormethod, the values obtained will be approximately twice thosedetermined by the straightedge feeler gage method.

Length:
The length or general steel tube:
Hot Rolling(Extrusion) tube: 3~12 m
Cold Drawn(Cold Rolled) tube: 3~8 m
The length for water pipe & boiler steel pipe:
Hot Rolling(Extrusion) tube: 4~12 m
Cold Drawn(Cold Rolled) tube: 4~8 m
Bending tolerance:
WT≤15mm, Bending≤1.5mm/m
WT＞15mm, Bending≤2.0mm/m
End shape:

burrs
Mechanical property
Heat treatment of longitudinal mechanical properties of steel pipe
shall according to the standard.

Hardness:
For the tubes which W.T. ≥2 mm, Rockwell hardness tests should be
taken.
Tests of the seamless boiler tubes:
1.Bending Test:
The tubes should take the bending test when OD ≤22mm. The bending
angle is 90 degrees, and the bending radius is 6 times the outer
diameter of the steel tube.
2. Hydraulic test;
Eddy current testing, ultrasonic testing can be used instead of
hydraulic tests. When eddy current testing, GB/T 7735-1995 Gr. A
should be followed; when ultrasonic testing, GB/T 5777-1996 Gr. C8
should be followed.
3. Flattening test
4. Flanging test
5. Expand test
