Description
What is Zinc Plated/Coated Hydraulic Steel Tubing?
Zinc-plated/coated hydraulic steel tubing refers to steel tubes that have been coated with a layer of zinc through a process known as zinc plating or galvanization. This coating provides several benefits, especially in hydraulic systems.
1. Zinc Plated Steel Hydraulic Tubing Coating Standard:
- The standards for zinc-plated steel hydraulic tubing can vary based on the region and application. Common standards that might be applicable include:
- ASTM B633: Standard Specification for Electrodeposited Coatings of Zinc on Iron and Steel
- ISO 4042: Fasteners - Electroplated Coatings
- DIN 50961: Electrodeposited coatings of zinc on iron and steel
2. Zinc Plated Steel Hydraulic Tubing Material Grade:
- The base material for hydraulic tubing is typically carbon steel. Common material grades for the base steel may include:
- ASTM A513: Standard Specification for Electric-Resistance-Welded Carbon and Alloy Steel Mechanical Tubing
- DIN 2391: Seamless Precision Steel Tubes
- SAE J524: Seamless Low-Carbon Steel Tubing Annealed for Bending and Flaring

3. Zinc Plated Steel Hydraulic Tubing Size:
- The size specifications for zinc-plated steel hydraulic tubing can vary widely based on the application and standards. Common size parameters include:
- Outer Diameter (OD): Typically ranging from fractions of an inch to several inches, depending on the application.
- Wall Thickness: Varies based on the tubings intended use and the pressure requirements of the hydraulic system.
- Length: Customarily available in standard lengths or cut to specific requirements.
4. Zinc Plated Steel Hydraulic Tubing Advantages:
- Corrosion Resistance:Zinc plating provides a protective layer that enhances the tubings resistance to corrosion, a critical factor in hydraulic systems.
- Durability:The zinc coating improves the tubings durability, making it more resilient to wear and tear associated with hydraulic applications.
- Extended Lifespan:The corrosion resistance and enhanced durability contribute to a longer lifespan, reducing the need for frequent replacements.
- Aesthetic Improvement:Zinc plating enhances the tubings appearance, making it more visually appealing.
- Identification:The distinctive appearance of zinc-plated tubing facilitates easy identification in manufacturing, installation, and maintenance processes.
- Cost-Effectiveness:Zinc-plated steel tubing is often more cost-effective than alternatives like stainless steel, providing a balance between performance and cost.
- Compatibility:Zinc plating is generally compatible with various hydraulic fluids, ensuring versatility in different hydraulic system applications.
5. Zinc Plated Hydraulic Steel Tubing Color:
Hydraulic galvanized tubes typically exhibit a silver-white or bright silver color. This is due to the zinc coating on the surface of the hydraulic galvanized pipes, which reflects light and gives the pipes a bright appearance. This bright silver color is commonly seen in many applications, especially in industrial settings for pipelines, hydraulic systems, and more. In some cases, depending on the galvanization method and the specific process used, hydraulic galvanized pipes may have a slight bluish-gray tint.
Additionally, if a specific color is desired for hydraulic pipes, such as red, blue, green, etc., it can be achieved by applying a colored coating or dye to the surface of the galvanized pipes. These colored hydraulic galvanized pipes not only offer decorative appeal but also retain the corrosion-resistant properties of the galvanized layer, making them practical for various applications with special decorative or identification requirements.
