Packing and transport:

Customer case：

    Australian customer purchase powder coating pre galvanized steel square tube. After customers receives the goods for the first time . Customer tests adhesive strength between the powder and the surface of the square tube .Customers test powder and square surface adhesion is small . We have meetings with customers to discuss this problem and we do tests all the time . we polished the surface of the square tube . Send the polished square tube to the heating furnace for heating . We tests all the time and discuss with customer all the time . We keep finding ways . After many tests, the final customer is very satisfied with the products. Now customer purchase a large number of products from factory every month .

Black steel pipe, named for its black surface, is a type of steel pipe without any anti-corrosive coating. It has a wide range of applications across various fields, including:

1. Transporting Natural Gas and Liquids:

   - Black steel pipes are commonly used for transporting natural gas, liquids, oil, and other non-corrosive fluids due to their high strength and pressure resistance, which allows them to withstand high working pressures and temperatures.

2. Construction and Structural Engineering:

   - In construction and structural engineering, black steel pipes are used to make frameworks, supports, beams, and columns. Their high strength and durability make them essential for building large-span structures and high-rise buildings.

3. Mechanical Manufacturing:

   - Black steel pipes are widely used in the mechanical manufacturing industry for making frames, supports, shafts, rollers, and other components of machinery and equipment.

4. Fire Protection Systems:

   - Black steel pipes are often used in fire protection systems for sprinkler systems and water supply pipes because they can withstand high temperatures and pressures, ensuring normal water supply during a fire.

5. Boilers and High-Pressure Equipment:

   - In boilers, heat exchangers, and high-pressure vessels, black steel pipes are used to transfer high-temperature, high-pressure fluids, maintaining stability and safety under extreme conditions.

6. Electrical Engineering:

   - In electrical engineering, black steel pipes are used for laying power transmission pipelines and cable protection pipes, protecting cables from mechanical damage and environmental influences.

7. Automotive Industry:

   - In the automotive industry, black steel pipes are used to manufacture exhaust pipes, frames, chassis, and other structural components of vehicles.

8. Agriculture and Irrigation:

   - Black steel pipes are used in agricultural irrigation systems due to their durability and corrosion resistance, ensuring long-term stable water supply for irrigation needs.

### Advantages of Black Steel Pipes

- Low Cost: The manufacturing cost of black steel pipes is relatively low because they do not require complex anti-corrosion treatments.

- High Strength: Black steel pipes have high strength and load-bearing capacity, allowing them to withstand significant external forces and internal pressures.

- Ease of Connection and Installation: Black steel pipes are relatively easy to connect and install, with common methods including threaded connections, welding, and flanges.

### Considerations

- Anti-Corrosion Treatment: Since black steel pipes are not anti-corrosive, additional anti-corrosion measures are needed in corrosive environments, such as applying rust-proof paint or using anti-corrosion agents.

- Not Suitable for Drinking Water: Black steel pipes are typically not used for transporting drinking water because they can rust internally, potentially affecting water quality.

Overall, black steel pipes are indispensable in various industries due to their excellent mechanical properties and wide range of applications.
