Product Uses

1. Fire Protection Systems

In fire protection pipelines, sockets are used to connect and extend water pipes, ensuring the system's sealing and stability. They are widely used in fire extinguishing and sprinkler systems to connect fire-fighting equipment and pipes, ensuring a stable water supply for firefighting.

2. Industrial Pipelines

In industries like oil, chemical, and natural gas, sockets are used to securely connect pipelines, ensuring stable fluid transport under high pressure and temperature. They are commonly used in oil drilling platforms, chemical plants, and other industrial applications, helping maintain the efficiency of pipeline systems.

3. Building Water Supply and Drainage Systems

In building water supply and drainage systems, sockets are used to connect different pipelines, ensuring smooth water flow. They are commonly used in residential and commercial buildings for water supply and drainage connections, providing stable water sources and drainage functions.

4. HVAC (Heating, Ventilation, and Air Conditioning) Systems

In HVAC systems, sockets are used to connect hot and cold water pipes or air ducts, ensuring that fluids do not leak during system operation. They help connect pipelines between different equipment, ensuring the efficient operation of temperature control systems.

5. Municipal Pipeline Systems

In municipal water supply, drainage, and wastewater treatment systems, sockets are used to connect and secure different pipe sections, ensuring stable water flow. They play an important role in municipal infrastructure and are widely used in urban water supply, wastewater treatment, and other areas.

6. Agricultural Irrigation Systems

In agricultural irrigation systems, sockets are used to connect irrigation pipes, ensuring even distribution of water to various irrigation areas. They are widely used in various farmland irrigation systems, helping improve irrigation efficiency and ensuring stable agricultural production.
