Product Description
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.
Condition:
1.Round seamless stain le ss mechanical tubing is generallysupplied in the cold-worked and annealed condition (see 5.2through 5.4). Square, rectangular, or other shapes of tubing aregenerally supplied annealed prior to final cold shaping. If someother condition is desired, details shall be included in the order.
2.The thermal treatment for ferritic and martensitic steelsshall be performed by a method and at a temperature se lectedby the manufacturer unless otherwise specified by the pur-chaser.
3.Unless otherwise specified. all austenitic tubes shall befurnished in the annealed condition. The anneal shall consist ofheating the material to a minimum temperature of 1900 F

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
