Understanding China EN857 2SC A Comprehensive Overview of Quality and Application in Hose Manufacturing

In the ever-evolving landscape of industrial manufacturing, the demand for high-quality hydraulic hoses is more pressing than ever. Among the vast array of products available in this sector, the China EN857 2SC stands out as a crucial component for various applications, particularly in hydraulic systems. This article aims to delve into the specifics of this standard, its manufacturing process in China, its applications, and the benefits it offers to industries worldwide.

What is China EN857 2SC?

The EN857 2SC standard is part of the European Norm (EN) regulations governing hydraulic hoses. The '2SC' designation refers specifically to a type of wire braided hydraulic hose, which is designed to handle high-pressure applications efficiently. This hose typically features a two-wire braided construction, making it suitable for various hydraulic fluids such as mineral oils, water-based fluids, and even certain bio-degradable fluids. The construction of EN857 2SC hoses enables them to withstand pressures up to 400 bar (approximately 5800 psi) depending on the hose diameter.

Manufacturing Process in China

Over the past few decades, China has emerged as a global hub for manufacturing hydraulic hoses, including those conforming to the EN857 2SC standard. The production process involves several crucial steps, including material selection, extrusion, braiding, and quality testing.

1. Material Selection The primary materials used for the inner tube of the hose are synthetic rubber compounds, which provide excellent resistance against oils and environmental factors.

2. Extrusion The selected rubber is then extruded to create the inner tube. This step requires precision to ensure uniform thickness, which is critical for maintaining pressure integrity.

3. Braiding The braided layer, typically made from high-tensile steel wire, is applied next. This layer is what gives the hose its strength and ability to withstand high pressure. Advanced machines ensure that the braiding is tight and evenly distributed, resistant to crushing and abrasion.

4. Final Assembly After the braiding is complete, an outer layer of rubber is applied to protect the steel wire and inner tube from environmental elements.

5. Quality Testing Each hose undergoes rigorous testing, including pressure tests and durability assessments, to ensure that it meets the EN857 2SC standards. This quality control step is crucial to guarantee the safety and efficacy of the hoses in real-world applications.

Applications of EN857 2SC

- Construction Used in heavy machinery like excavators and dump trucks for hydraulic fluid transfer. - Agriculture Essential for tractors and other farming equipment that rely on hydraulic systems for functionality. - Automotive These hoses are utilized in hydraulic braking systems, ensuring safety and performance in vehicles. - Manufacturing In factories, they are vital for powering hydraulic presses, lifts, and other machinery.
