Description

BMI (Black Malleable Iron) fittings are commonly used in plumbing, fire protection, and industrial applications. They offer a balance of strength, durability, and cost-effectiveness.

Here’s a breakdown of common BMI fittings:

1. Hex Nipples: Short, straight fittings with male threads on both ends for connecting pipes.
   
2. Long Nipples: Similar to hex nipples but with a longer length for increased pipe separation.
   
3. Elbows: Used to change the direction of a pipe at a 90-degree angle.
   
4. Tees: Create a branch in a pipe, allowing for additional connections.
   
5. Crosses: Create a four-way branch in a pipe.
   
6. Reducer Bush: Connects two pipes of different diameters.
   
7. Reducer Couplings: Connect pipes of different diameters with a coupling.
   
8. Plugs: Seal the end of a pipe.
   
9. Caps: Close the end of a pipe with a threaded cap.

Benefits

1. Strength and durability: Able to withstand moderate pressures and temperatures.
   
2. Corrosion resistance: Offer good resistance to corrosion in many environments.
   
3. Threaded connections: Easy to install and disassemble.
   
4. Cost-effective: Generally more affordable than other materials like stainless steel or brass.
   
5. Wide availability: Easily found in various sizes and configurations.
