The act of threading a pipe involves the forming of screw threads on its internal surface. Most commonly, this procedure is employed for securing pipes and fittings together or remedying broken threading.
When it comes to piping, there are two distinct threading types.
The threads of pipes and hydraulic components twist inwards progressively, creating an opposing resistance that tightens their seal when in place. Tapered threads are thus a mainstay in the plumbing and hydraulics industry due to their uniquely designed shape.
ANGULAR and unwavering, parallel threads have no tendency to constrict as they are manipulated – a fact that makes them ideal for use in low-pressure applications including water lines.
Working with pipes can be a tedious job but thanks to advancements in tools, it can be done both by hand and through power. Hand-operated methods are slow and limited to smaller pipes whereas power-threading is much more expedient and suited for larger ones. Threading by hand requires a die and handle, but with a power tool, the task can be easily achieved.
In order to begin the power-threading process, the tap must securely fasten to the machine. This cylindrical object, with edges embedded with precision-cut teeth, is tightly attached to the electricity-driven apparatus using a chuck.
To ease the process, lubrication is called for. Both the die and the pipe should be lightly oiled – this will ensure that no impediments arise in terms of the threading and also guarantee a seamless experience.
After securing the die and applying its helpful lubrication, it is time to put it into action. Turning the die slowly while it is pressed against the pipe will begin the threading process. As the die continues to rotate, its movement will result in perfect threads etched onto the surface of the tube.
To conclude the project, we must extract the die from the conduit. It can be achieved manually, or if more support is required, through the use of a powered device.
An uncomplicated technique, pipe threading can be carried out manually or with a powered device. Primarily employed for joining up pipes and their fixtures, or to fix deteriorating threads, this practice is in broad usage around the world.
