DESTRUCTIVE TESTS

FLARING TEST

The flaring test serves to establish the forming behavior of tubes or pipes which is expanded to specific degree. This flaring test is carried out in conformity with the code requirements. The specimen to be tested is expanded in a press to the degree specified. Defects which occurs as result of this process are not permissible.

HARDNESS TEST

Samples from each lots are tested to ensure that the hardness of the tube is within permissible limits.

THE TENSILE TEST

The tensile test specimen serves to determine the strength and ductility characteristics i.e. yield strength, tensile strength and elongation. Tensile tests are normally carried out at the room temperature according to DIN, ASTM, BS standards etc.

REVERSE TEST

This test in done to check the welding strength of the tube.

FLATTENING TEST

Flattening test mainly serves to detect microscopic internal and external flaws. It involves compressing a tubular ring between two planes parallel placed to a predetermined distance. Incipient cracks and internal or external defects which occur as result of this process are not permissible. The flattening test is conducted as described in ASTM A450 / SDYM S530.etc.

LABORATORY TEST

The modern chemical laboratory of Maven Stainless is fully equipped to handle all chemical tests which are used in pickling process and also equipped for testing of chemical elements like C, Ni, Si, Mo, Mn P, etc.
