ASTM A213 / ASME SA213 Seamless Precision Stainless Steel Tubing S30400 /30403 For Food Industry

Product Description

ASTM A213 / ASME SA213 Stainless Steel Precision Seamless Tube, S30400 /30403 For Food Industry

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 )

MTSCO has the most advanced technology — The floating plug drawing technology which are used in Korea , and equipped with the most environmentally process — Bright annealing process . So our bright annealed precision tube produce technology make us can produce 300 tons high precision tubes every months .
