Process for making upsets for oilfield drill pipe
Pipe to be upset is conveyed via walking beam though a series of induction heating coils and one end is heated to a maximum temperature of 2350 degrees F. Thereafter, a robot transports the pipe into a forging machine where the pipe end is upset in one or more die pockets. For those types of pipes w...

| description | Pipe to be upset is conveyed via walking beam though a series of induction heating coils and one end is heated to a maximum temperature of 2350 degrees F. Thereafter, a robot transports the pipe into a forging machine where the pipe end is upset in one or more die pockets. For those types of pipes where the pipe end temperature falls below an acceptable temperature during upsetting, the robot delivers the pipe end to an auxiliary induction heating coil and is re-heated to an acceptable forging temperature. The robot then transports the pipe back into the forging machine where the pipe end is forged to its final upset dimensions. |
