Key Features of Phosphated Tubes
Phosphated tubes, specifically DIN/EN black phosphated precision seamless steel tubes, offer a host of advantages that make them invaluable in various industries. Here are some key features:
1. Black Phosphated Coating
These tubes are coated with black phosphate on both sides, providing a layer of protection that enhances their durability.
2. Delicate Coating
The phosphated coating is delicate, with high lubricity and uniform color. This ensures a smooth surface that meets the highest quality standards.
3. Aesthetic Appeal
Phosphated tubes are not only functional but also visually appealing. Their good-looking appearance adds an element of sophistication to the end product.
4. Corrosion Resistance
One of the standout features of phosphated tubes is their high resistance to corrosion and rust. This makes them ideal for applications in harsh environments.
5. Paint-Friendly
Phosphated tubes have excellent paint adhesion properties, allowing for strong bonding when painted or spray-treated.
Technical Characteristics of Phosphated Tubes
Understanding the technical aspects of these tubes is crucial for their successful integration into various applications:
1. Standard
Phosphated tubes adhere to international standards, including DIN2391/C (EN10305-1), EN10305-4 (DIN2445), and SAE J524.
2. Grade
They are available in various grades, such as E235 (ST35, ST37.4), E255 (ST45), and E355 (ST52).
3. Heat Treatment
Phosphated tubes undergo NBK (+N) normalization to ensure consistent quality.
4. Surface Treatment
They feature a bright surface finish, achieved through cold drawing.
5. Straightness
Phosphated tubes maintain a high level of straightness, with a deviation of 10μm per meter.
6. Delivery Conditions and Packaging
To meet the diverse needs of customers, phosphated tubes are delivered in various conditions:
a. Goods: NBK (+N)
b. Packaging: Both ends are sealed with plastic caps, bundled with plastic film, and wrapped in woven bags. Each bundle can weigh up to 1000 kg.
c. Length: Tubes are typically supplied in fixed 6-meter lengths or as per customer requirements.
Applications of Phosphated Tubes
These versatile tubes find applications in a wide range of industries, including:
1. Engineering Machinery: Phosphated tubes offer durability and corrosion resistance, making them suitable for various components in engineering machinery.
2. Ships: Their resistance to rust and corrosion makes phosphated tubes essential for marine applications.
3. Precision Machinery: These tubes play a vital role in precision machinery due to their high-quality surface finish and corrosion resistance.
4. Hydraulic and Pneumatic Systems: The consistent quality and resilience of phosphated tubes make them a preferred choice in hydraulic and pneumatic systems.
Furthermore, the surface of phosphated precision steel tubes is especially well-suited for painting or spray treatment. The strong adhesion of paint enhances the appearance and significantly improves rust prevention.
