    Product Detail

    Hot-dip galvanized pipes are manufactured by cleaning and pickling steel pipes, dipping them in molten zinc at around 450°C, and then cooling and inspecting them for coating quality. This process forms a strong, uniform zinc layer that protects the steel from corrosion, enhances durability, and ensures long service life, making the pipes ideal for construction, scaffolding, water, and gas applications.

    Galvanized pipes have a wide range of applications in construction, industry and other fields. It is very important that the packaging of galvanized pipes and the handling during transportation be adequate to deliver the products safely to prevent coming of rust, deformation or damage due to the nature of environment during shipment. The packing requirements, ways and precautions are summarized as following.

    1.Packaging Demands

    Clean and dry surface: the pipes should be clean without oil and dust.

    Protective Wrapping: Apply double packaging, inner packaging transparent polyethylene film(≥0.02 mm), outer packaging is plastic coated paper or sheet(≥0.5 mm).

    Labeling: Each package should be labeled with type, specification, batch number and production date clearly.

    Classification: Pipe off by spec, size, length for loading/unloading, storing in a convenient way.

    2.Packaging Method

    Surface treatment: Pipes are cleaned and dried prior to packaging to prevent corrosion.

    End Protection: End protection: Cork splints or equivalent supports at both ends to protect against distortion in transit.

    Moisture & Rust Proof: The over wrapping and container lining material must be moisture, water and rust resistant.

    Protection in storage: Don’t expose to sun light or damp places for long time after packaging.
    Cautions Unify: The size and length of the tubes in the package to avoid the mismatch and waste. Make sure the modules are properly labeled and classified so that the warehouse can easily manage in the warehouse. Maintain stable stacking, no tilting or too high stacking to prevent the fall and the damage. Following these instructions, galvanized pipes can be well protected in transport and the delivery can be assured safe and sound in the destination.
