Die heads, doughnut-shaped tools, are attached to pipe threading machines used in plumbing construction and similar applications. They can be easily affixed to both automatic and manual threading machines.
Equipped with threading blades (known as chasers), die heads are fastened to threading machines for cutting threads on pipes.
The advantage of using die heads is the versatility they offer: a single threading machine can handle various pipe diameters simply by swapping out the die head.
When using a die head, ensure it is securely attached to the pipe, aligning the chaser according to the required diameter and direction.
Once the die head with the chaser is affixed to the threading machine, double-check the fixation to ensure it's properly secured.
For manual feed-off die heads, unlike automatic ones, the operator must closely monitor and control the feed-off timing.
To select the appropriate die head, consider four key factors:
It's important to use a die head that is specifically designed for the chosen automatic threading machine.
For pipe threading, "A" designations are used in the millimeter system, and "B" designations in the inch system. For instance, a 34 mm outer diameter pipe is nominally referred to as 25A (or 1B), and a corresponding die head should be selected. In the inch series, common names are also used.
Many die heads are adjustable to fit various pipe diameters, with a wide range available, from the smallest (8A to 10A) to the largest (65A to 100A). Additionally, the pipe material, especially stainless steel, may necessitate different types of die heads.
