Galvanized Steel Pipe Couplings are high-quality pipe fittings designed for HVAC equipment and other piping systems, with excellent corrosion resistance and versatility. The following is a detailed description of the product: 

1. **Material and Production**

- Made of high-quality seamless pipe cutting to ensure high strength, pressure resistance and durability.

- The material is usually carbon steel, and the surface is electro-galvanized to improve corrosion resistance.

 2. **Production Process**

- **Cutting**: Seamless pipes are precisely cut to ensure accurate dimensions.

- **Electro-galvanizing**: The cut pipe fittings are electro-galvanized to form a uniform zinc layer, which effectively prevents rust and prolongs service life.

- **Thread Processing**: CNC machine tools process various standard pipe internal threads to ensure the accuracy and consistency of the threads.

 3. **Thread Standard**

- Supports a variety of international standard threads, including:

- **BSP**: International general pipe thread

- **ISO228-1**: Non-sealed pipe thread.

- **NPT, NPSC**: American standard pipe thread.

- **DIN2999 (German standard).

- **G (Russian standard)** and other countries' thread standards.

- Specific thread standards can be customized according to customer needs to meet the diverse needs of the global market.

 4. **Product standards**

- **BS EN10241**

- **ASTM A865**

- **DIN 2986**

- **GOST 8966**

 5. **Specifications and parameters**

- **Specifications**: DN6~DN150 (1/8"~6").

- **Steel pipe**: SCH40, SCH80, SCH160, XS, XXS, etc.

- **Process**: cutting, external treatment, machining, rust prevention, packaging.

 6. **Application scenarios**

- Electrogalvanized threaded pipe Couplings provide excellent rust resistance and are suitable for low-pressure and medium-pressure pipeline systems in humid or corrosive environments, as well as occasions that require corrosion resistance and high sealing.

 7. **Customized service**

- Pipe Couplings with different specifications, thread standards and electrogalvanized thickness can be customized according to customer needs to meet the needs of specific application scenarios.
