Thick Wall Seamless Stainless Steel Pipe for Mechanical ASTM A511 TP316 304

Covering seamless stainless tubing foruse in mechanical applications where corrosion-resistant orhigh temperature strength is needed.

Covering 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.

Tolerance for seamless stainless tube:

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:
Both ends of the pipe should be cut at right angles, and remove 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
