Tip shape

The end faces of the steel pipe should be perpendicular to the axis of the steel pipe and the burrs are removed.

 

 

Items of Testing

Hydraulic test:

The steel pipe shall be hydraulically tested one by one. 

Flattening test:

Steel tubes with a wall thickness of not more than 10 mm shall be subjected to a flattening test

Flaring test:

A steel pipe having a wall thickness of less than or equal to 10 mm can be subjected to a flare test. 

Intergranular corrosion test:

Austenitic and austenitic-ferritic steel tubes can be tested for intergranular corrosion.

 

Use:

Used in mechanical structures, fluid pipes, boiler superheaters, heat exchangers, condensers, catalytic tubes, etc.
