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
