Hydraulic systems typically use tubing or hoses made from materials that can withstand high pressure and are compatible with hydraulic fluids. The choice of tubing or hoses depends on the specific application, pressure requirements, and environmental factors. Here are some common types of tubing and hoses used for hydraulics:

 

Steel tubing is a common choice for hydraulic systems due to its strength and durability. It comes in various sizes and thicknesses to accommodate different pressure levels. Seamless steel tubing is preferred because it has no welds, reducing the risk of leakage.

 

Stainless steel tubing is often used in applications where corrosion resistance is crucial. It is especially suitable for hydraulic systems in marine or corrosive environments.

 

Hydraulic hoses are made from rubber or synthetic materials reinforced with layers of braided wire or spiral-wound wire. These hoses are flexible and can handle a wide range of pressures. They are often used in mobile equipment and machinery where flexibility is important.

 

Thermoplastic hoses are lightweight and flexible, making them suitable for applications where weight reduction and flexibility are critical. They are used in various industries, including construction and agriculture.

 

Nylon tubing is another lightweight option that is resistant to abrasion and chemicals. It is commonly used in low-pressure hydraulic systems and air brake systems.

 

Composite hoses consist of multiple layers of different materials, such as thermoplastic, fabric, and wire. They are designed to handle specific applications with unique requirements, such as chemical resistance.

 

Copper tubing is used in some specialized hydraulic systems, particularly those involving high-temperature applications. Coppers excellent heat conductivity can be advantageous in certain situations.

 

Aluminum tubing is lightweight and corrosion-resistant, making it suitable for some hydraulic applications, especially in the aerospace industry.

 

The choice of tubing or hoses should take into consideration factors like pressure ratings, temperature range, compatibility with hydraulic fluids, flexibility, and the specific demands of the hydraulic system. Proper installation and maintenance are crucial to ensure the longevity and performance of the hydraulic components. Its also essential to follow industry standards and guidelines for hydraulic tubing and hoses to ensure safety and reliability.
