Tape duct tape over one end of the steel tube. Fill the tube completely full of sand and duct tape the end shut.
Tighten the tube vertically into a bench vise, just below where you want the bend in your tube to start.
Use a torch to heat 3 inches of the tube, starting at where it is tightened into the vise. Heat the tube until it is glowing red hot.
Slide the larger steel tube or pipe about 6 to 12 inches onto the top of the tube you heated with the torch. This tube will be used as a leverage device to bend the square tube.
Bend the tube slowly by pulling the leverage tube toward yourself. Reheating with the torch may be needed to complete the bend you desire.
