Hydraulic pipes are an important part of hydraulic systems, as they carry fluid that transmits pressure and energy in the system. Hydraulic pipes must withstand high pressure and extreme conditions, so their choice is very important to ensure the durability and efficiency of the system. The most widely used are steel galvanized hydraulic pipes, as well as stainless steel hydraulic pipes, which are extremely resistant to corrosion, so they are often used in aggressive environments or with manger liquids. Stainless steel hydraulic pipes are well suited for hydraulic marine systems. Aluminum or copper hydraulic pipes can also be chosen. They are used where lightness is important and there are average pressure loads, for example, in aviation.
