GB5310 12Cr1MoVG boiler steel pipe Chemical Composition and Mechanical Property

Testings
(1)Hydraulic test
The steel pipe shall be hydraulically tested one by one, and the eddy current testing can instead of the hydraulic test.
(2)Flattening test
Steel pipes with an outer diameter greater than 22 mm to 400 mm and a wall thickness not greater than 40 mm shall be subjected to a flattening test.
(3)Bending test
Steel pipes with an outer diameter greater than 400 mm or a wall
(4)Flaring test
The steel pipe with an outer diameter of not more than 76 mm and a wall thickness of not more than 8 mm can be used for the flare test.
(5)Low-power test
Steel pipes should be tested at low magnification. Visually visible white spots, inclusions, subcutaneous bubbles, tumbling and delamination are not allowed on the cross-section acid immersion test piece.
(6) Non-metallic inclusions
Steel pipes shall be tested for non-metallic inclusions.
(7)grain size
The finished steel pipe should be tested for grain size.
(8)Microstructure
The finished steel pipe will be ferrite plus pearlite, allowing the presence of granular bainite, and no phase change at critical temperature between AC1 and AC3 is allowed.
(9)Decarburization layer
Cold drawn (rolled) finished steel pipes with an outer diameter of not more than 76 mm shall be inspected for the total decarburization layer.
(10)Non-destructive testing
The steel pipe shall be ultrasonically inspected and tested in accordance with the provisions of GB/T 5777.
