A Pipe Threading Machine with Dies is a specialized tool used to cut threads into the ends of pipes, typically for joining two or more pipes together with fittings. It is commonly used in plumbing, construction, and manufacturing, particularly when working with GI (Galvanized Iron) pipes and conduit pipes (used for electrical wiring).

Key Features of a Pipe Threading Machine:

1. Thread Cutting Function:

   • The primary purpose of the machine is to cut precise threads on the ends of pipes, making it easier to connect them with threaded fittings (like elbows, tees, couplings).
   • The machine uses dies (special cutting tools) that are specifically designed to cut threads of a certain size and type, such as NPT (National Pipe Thread), BSPT (British Standard Pipe Thread), or other thread standards.

2. Dies for GI/Conduit Pipes:

   • GI Pipes: Galvanized Iron pipes are coated with zinc to resist corrosion. A pipe threading machine with dies for GI pipes ensures the proper cutting of threads on these pipes, which are commonly used in plumbing, gas, and industrial applications.
   • Conduit Pipes: Electrical conduit pipes, typically made of steel or aluminum, are used to protect electrical wiring. The threading machine can thread these pipes to create secure connections between sections of conduit in electrical installations.

3. Manual or Automatic Operation:

   • Manual Machines: These require the operator to manually rotate the pipe while the machine cuts the threads. This type of machine is generally used for small to medium-sized projects.
   • Automatic or Semi-Automatic Machines: These machines automate the threading process, making them faster and more efficient for large volumes of threading work. They may feature an electric motor to rotate the pipe and the dies, reducing the operator's physical effort.

4. Variable Dies and Thread Sizes:

   • The threading machine is equipped with a set of dies that can be swapped to create different pipe sizes and thread profiles.
   • Pipe Sizes: These machines can typically handle a range of pipe diameters, from small diameter pipes (like 1/4-inch) to larger ones (up to 4 inches or more), depending on the machine's capacity.

5. Built-In Lubrication:

   • Pipe threading machines typically feature a built-in lubrication system or oil bath to minimize friction during threading, which helps to achieve smoother, cleaner threads and prolongs the life of the dies and machine components.

6. Adjustable Speed:

   • Some advanced machines offer speed adjustments to suit different materials or threading requirements. Slower speeds may be used for tougher materials like GI pipes, while faster speeds may be appropriate for softer metals.

7. Portable or Stationary Designs:

   • Portable Machines: Some threading machines are compact and designed for use in the field, allowing the operator to thread pipes on-site.
   • Stationary Machines: Larger, industrial-grade machines are typically stationary and used in workshops for high-volume threading tasks.

Types of Dies for GI and Conduit Pipe Threading:

• GI Pipe Dies: These dies are specifically designed to cut threads into galvanized iron pipes. They are available in different thread profiles, including BSPT or NPT, depending on the region or application.
• Conduit Pipe Dies: These dies are designed for electrical conduit pipes, often in sizes that are standardized for electrical systems (like EMT – Electrical Metallic Tubing, Rigid, or IMC – Intermediate Metal Conduit). These dies ensure the threads are accurate and uniform for making electrical connections.

Applications:

1. Plumbing: GI pipes are frequently used in plumbing systems, and threading these pipes is essential for creating tight, secure connections.
2. Electrical: Conduit pipes are used to protect electrical wires. Threading the ends of the conduit allows fittings to be securely attached, ensuring the protection of the wiring.
3. Industrial Systems: Both GI and conduit pipes are commonly used in industrial applications for gas, water, or electrical systems. Threaded connections allow for easy assembly and disassembly of systems.
4. Gas and Oil Pipelines: Threading machines are also used in the gas and oil industry for joining metal pipes used in transporting gas or liquids.

Advantages of Using a Pipe Threading Machine:

1. Precision: The machine ensures consistent, accurate thread cutting, which is essential for creating secure pipe connections.
2. Time Efficiency: Automatic and semi-automatic machines can significantly reduce the time needed to cut threads on multiple pipes compared to manual threading methods.
3. Durability: A properly maintained threading machine with quality dies can handle the tough, durable materials of GI and conduit pipes, providing reliable service over time.
4. Consistency: Machines ensure that each thread is uniform in size and shape, which is critical for ensuring leak-proof connections in plumbing or electrical systems.https://store.unigulfsupply.com/product/gi-pipe-conduit-threading-machine/
