TP304 / 304L Precision Stainless Steel Seamless Tube, ASTM A269 / ASME SA269
1 . Annealing of mother tuber ensures :
A) Removal of stress induced during tube forming and cold drawing
B) Sufficient ductility and softness for cold drawing
C) Transformation of the weld zone to austenitic nature
D) Re crystallization of metallic grains to original form and thereby improving corrosion resistance
2 . The tubes are then coated with proper lubricant and then cold drawn over a drew bench
1) To vary the metallurgical structure and restore the properties
to the parent material
2) To achieve a tube having closer dimensional tolerances
3) To produce tubing of smaller size and wall thickness
4) To reorient the grain structure of weld portion with that of the
parent material
5) To remove/minimize the internal bead
Test :
1 . NTD ( Ultrasonic test , Eddy Current test )
2 . Mechanical Test ( Tension Test , Flaring Test , Flattening Test , Hardness Test , Hydraulic test )
3 . Metal Test ( Metallographic Analysis , Impact Test-High / low temperature )
4 . Chemical Analysis ( Photoelectric Emission Spectroscopic )
