DIN Black Phosphated Hydraulic Tube in High Precision

Introduction

In the world of hydraulic systems and machinery, precision and reliability are of utmost importance. Our DIN Black Phosphated Hydraulic Tube is engineered to meet the highest industry standards, ensuring exceptional performance and longevity in various applications. Designed for global markets, our products stand out due to their remarkable quality, meticulous manufacturing processes, and advanced material characteristics.

Overview of Manufacturing Process

The foundation of our DIN Black Phosphated Hydraulic Tube lies in the use of cold drawn and bright NBK seamless steel tubes. These tubes undergo a phosphating process using imported chemical fluids, which create a black film on the surface. This film not only enhances the corrosion resistance of the tube but also promotes the absorption of antirust oil through micro-pores, effectively protecting the tube from rust formation. To maintain optimal hygiene during transit, both ends of the tube are securely capped to prevent dust contamination.

Key Features

• Bright Black Appearance: The uniform black coloration ensures an aesthetically pleasing finish while also serving a functional purpose in corrosion resistance.

• Superior Antirust Properties: The phosphated layer provides a robust defense against oxidation, significantly extending the product's lifespan in challenging environments.

• High Precision Manufacturing: Our tubes are manufactured under stringent quality control measures to achieve high precision and dimensional accuracy, making them reliable components in hydraulic systems.

Applications

Our DIN Black Phosphated Hydraulic Tube is primarily utilized in:

• Hydraulic Systems: These tubes are vital components in hydraulic machinery, providing the necessary strength and durability to withstand challenging operating conditions.

• Card Connectors and Pipe Joints: Our hydraulic tubes serve as nested card connectors, ensuring secure and efficient connections in various applications.

Material and Mechanical Properties

We source the raw materials for our tubes from reputable suppliers, with steel grades including ST35, ST37.4, ST45, ST55, CK45, and ST52.4, primarily produced by Shanghai Baosteel Group. The mechanical properties of our steel tubes are exceptional:

• High Pressure and Impact Resistance: Our tubes can withstand high pressures and impacts, making them ideal for demanding hydraulic applications.

• Flexibility in Processing: The tubes can be cold bent at any angle without structural failure, allowing for flexibility in design and installation.

• Durability during Fabrication: No cracking occurs during flaring and flattening processes essential for industry requirements, ensuring seamless integration into final products.

Surface Quality Standards

The quality of the internal and external surfaces of our hydraulic tubes is paramount. We maintain strict standards to ensure:

• Clean Surfaces: Internal and external surfaces must be free from oxidation, cracks, folds, scars, or lamination defects.

• Strict Defect Tolerance: Any surface defects, such as scratches or concavities, must not exceed 0.025 mm, surpassing the DIN2391 standard requirements.

Our commitment to superior surface quality enhances the performance and reliability of our products in various applications.

Packaging for Protection and Transportation

To ensure the integrity of our hydraulic tubes during transit, we employ comprehensive packaging procedures:

• Antirust Oil Coating: Each tube is coated with specialized antirust oil to further guard against corrosion.

• End Caps: Both ends of the tubes are capped to prevent dust ingress.

• Protective Wrapping: The tubes are then wrapped in plastic film for added protection, sealed in either linen or wooden cases to withstand transportation challenges.

Quality Assurance

We are dedicated to upholding the highest quality standards throughout our manufacturing process. Each batch of our hydraulic tubes is accompanied by a Certificate of Quality Assurance, guaranteeing compliance with industry regulations and customer specifications.
