As per clause 404.2.2 of ASME B31.4, the Field bends or cold bends are defined as the pipe bends made in the field during pipeline construction to allow the pipe to conform to the ditch contour. They include horizontal bends and vertical bends (sags and overbends) to accommodate direction changes in direction, and combination bends.5. Mechanical Bending Machine. Mechanical bending refers to the use of motors, wheels, gears, or levers to initiate a compressive or tensile force on the metal workpiece. These metal bending machines can have automatic or manual operation modes. Pipe bending and plate rolling machines are two popular examples of mechanical bending.

It covers essential units of competencies in the two key qualifications in the UEE Electrotechnology TrainingA sheet metal brake is a machine that bends metal sheets into desired shapes and sizes. The machine works by clamping the metal sheet between two dies shaped to produce the desired bend. The dies are then brought together at high speed, forcing the sheet to bend and form around them. This process is called ‘braking’. Follow the steps from the 90° Stub-Up section to create the ideal bend for the connection on the first side. From the back edge of the 90° stub-up bend, measure the distance found in step 1 and make your mark on the conduit. Place the bender on the conduit with the bender’s hook facing the free end of the tube to be. Two kick bends in opposite directions. A 30° kick has a hypotenuse of 10".
