Categories of Hydraulic Tubes

The categories of hydraulic tubes mainly include: steel pipes, steel hoses, nylon pipes, rubber hoses, polyester elastic pipes, etc.

Steel pipes

Hydraulic steel pipes are one of the most commonly used pipes in hydraulic systems. They are made of hot-rolled or cold-drawn seamless steel pipes. They have good pressure resistance and long service life. They are often used in high-pressure and large-flow hydraulic transmission systems. Common hydraulic steel pipes include carbon steel pipes and other materials, which can meet the needs of different working conditions.

There are two main manufacturing processes for hydraulic steel pipes:

1. Seamless steel pipes made of hot-rolled steel strips through hot extrusion at high temperatures are often used in low-pressure hydraulic systems.

2. Made by cold drawing, it has the advantages of being smoother, more accurate in size, and better in detail processing, and is suitable for making precision tubes.

Steel hoses

Compared with steel pipes, steel hoses are softer, easier to bend, and lighter in weight. They are often used in low- and medium-pressure hydraulic transmission systems.

The steel wire hose consists of three parts: inner tube layer, reinforcement layer and outer layer:

1. The inner tube layer is usually made of polyester, polyurethane or chemically inert materials.

2. The reinforcement layer is woven from high-strength steel wire.

3. The outer layer is made of friction-resistant and corrosion-resistant rubber or plastic.

The more commonly used types of steel wire hoses are: high-pressure steel wire hoses, ultra-high-pressure steel wire hoses, steel wire spiral hoses, etc.

Nylon tube

Nylon tubes are mainly used in low-pressure hydraulic piping, air pipelines, liquefied gas tanks, compressed air systems and oil and gas pipelines. Its advantages are wear resistance, corrosion resistance, light weight, easy installation and maintenance. Nylon tubes also have the advantages of flame retardancy, insulation, and high temperature resistance, so they are also widely used in aviation, aerospace, shipbuilding and other fields.

Rubber hose

Rubber hoses consist of three parts: inner layer, reinforcement layer and outer layer, and are generally made of materials such as rubber, polyurethane and polyester. Rubber hoses have the properties of wear resistance, corrosion resistance, oil resistance, high temperature resistance, anti-static, etc., and can be used in high temperature, high pressure propulsion systems, hydraulic systems, air systems and other fields.

Polyester elastic tube

Polyester elastic tube is a flexible pipe used in low pressure pipeline systems. It has the characteristics of flexibility, pressure resistance, corrosion resistance, high temperature resistance, and low temperature resistance. It is widely used in hydraulic transmission systems, cooling systems, refueling and heat dissipation systems and other fields.

The above is an introduction to the main categories of hydraulic tubes. Different pipes have different uses and scopes of application. Choosing suitable hydraulic tubes can improve the service life and safety performance of mechanical equipment, engineering machinery, automobiles and other equipment.
