What is a Threaded Flange?

A threaded flange (also known as a screwed flange) is a type of flange that has internal threads, allowing it to be screwed directly onto a male-threaded pipe without welding.

• Ideal for low-pressure and non-toxic systems

• Commonly used in pipe sizes up to 4 inches (½”–4”)

• Designed for quick installation and dismantling

• Best suited for applications where welding is hazardous (e.g., explosive or flammable areas such as petroleum refineries, gas plants, chemical storage facilities)

Advantages:

• ✅ No welding required

• ✅ Quick installation & easy maintenance

• ✅ Suitable for hazardous/explosive environments

• ✅ Cost-effective for small bore piping
