A pipe threading machine is a mechanical or electric tool used to cut screw threads on the ends of metal pipes so they can be joined with fittings such as couplings, elbows, and tees. It typically consists of a motor, a rotating chuck to hold the pipe, cutting dies (threading tools), a carriage, and a lubrication system. These machines are commonly used in plumbing, construction, and industrial pipe installation to prepare pipes for secure and leak-proof connections.

Operation

When the machine is switched on, the motor rotates the pipe held firmly in the chuck. The operator positions the threading dies onto the pipe end using the carriage. As the pipe rotates, the cutting dies gradually cut spiral threads onto the outer surface of the pipe. Cutting oil is usually applied during the process to reduce friction, cool the dies, and improve thread quality. Once the required thread length is achieved, the dies are withdrawn, and the machine is stopped. The threaded pipe is then ready for fitting and installation.
