The applications of Rolled Grooved Galvanized Steel Pipe are extensive and include various pipeline systems, such as:

1. Fire Protection Systems:

   - These pipes are commonly used in fire sprinkler systems. The grooved design allows for quick connections, facilitating installation and maintenance, while the galvanized coating provides corrosion resistance.

 2. Water Supply Systems:

   - Rolled grooved galvanized steel pipes are frequently used in building water supply systems due to their corrosion resistance and high strength.

 3. HVAC (Heating, Ventilation, and Air Conditioning) Systems:

   - Used in heating and cooling water systems. The grooved design makes connection and disconnection easier, reducing installation time and costs.

 4. Natural Gas and Oil Transportation:

   - These pipes are suitable for transporting natural gas and oil because of their corrosion resistance and high strength.

 5. Industrial Pipeline Systems:

   - Widely used in various industrial fields, such as chemical, pharmaceutical, and food processing, for transporting various liquids and gases.

 6. Agricultural Irrigation Systems:

   - These pipes ensure long-term durability and reliability in agricultural irrigation.

 7. Sewage Treatment Systems:

   - Due to their corrosion resistance, these pipes are also suitable for sewage treatment plant pipeline systems.

 In summary, rolled grooved galvanized steel pipes are widely used in fields requiring durable and reliable pipeline systems because of their easy installation, strong corrosion resistance, and high strength.
