Final answer:
There are five types of pipe threading machine die heads: Universal, Circular, Hexagonal, Square, and Rectangular.
Step-by-step explanation:
In pipe threading machines, die heads are used to cut threads on pipes. There are several types of die heads available for different threading requirements:
- Universal: This type of die head is used for threading a wide range of pipe sizes.
- Circular: Circular die heads are used for threading pipes that require a smooth, continuous thread.
- Hexagonal: Hexagonal die heads are designed for creating hexagonal threads, which provide more grip and torque.
- Square: Square die heads are used to create square threads, which are often used in high-stress applications.
- Rectangular: Rectangular die heads are used for creating rectangular threads, which are commonly used in specialized applications.
