ASME SA213 TP304 Stainless Steel Seamless U Bend Tube for Heat
Exchange application
After U bend (cold forming), heat treatment of bending portion may
be required. nitrogen generating machine (to protect stainless
steel tube surface during annealing). Temperature is controlled
through the entire heat-treated area by fixed and portable infrared
pyrometers.
