A section of a tube will be flared with a tool to form a 60o wide in the opening of the tube. If after flaring, the tubes did not show any signs of cracks, dents and imperfections, then the set of tubes had passed the test. Such method is done to check the strength of welding line.

A hydrostatic test is performed by using water as the test medium. Performed under controlled conditions, a tube will be internally pressurized with air while submerged in water and is observed for leakage. Welded fabrications are frequently hydrotested for pressure tightness.

A standard test piece is gripped at either end by a suitable apparatus. A machine slowly exerts an axial pull so that the steel is stretched until it breaks. The test provides information on proof stress, yield point, tensile strength, elongation and reduction of area.
