Non-Welded Hydraulic Piping Systems
Product Description
Non-welded hydraulic piping systems are a reliable and efficient solution for the transportation of hydraulic fluids under high pressure. These systems are designed to withstand the demanding requirements of modern hydraulic machinery while offering increased strength, safety, and flexibility compared to traditional welded piping solutions. Made from high-quality seamless pipes, they ensure minimal risk of leaks and are ideal for fluid transmission in industries such as construction, automotive, and manufacturing.
Product Advantages
Materials
- Non-welded hydraulic piping systems are typically made from high-strength carbon steel, stainless steel, or alloy steel. The material is chosen based on the application’s pressure requirements, corrosion resistance, and temperature considerations. Stainless steel is often used in environments that require superior corrosion resistance, while carbon steel provides excellent strength and durability at an affordable cost.
International Standards:
- DIN 2391: Specifies the standard for precision seamless tubes.
- EN 10305-4: Defines the technical requirements for seamless cold-drawn precision steel tubes used in hydraulic systems.
These standards ensure that the hydraulic piping systems meet global safety and performance benchmarks.
