Baotou Steel GB/T17396 30CrMnSiA 27SiMn Hydraulic Prop Steel Pipe

Hydraulic prop tubes are a type of steel pipe specifically used for manufacturing hydraulic supports and cylinders, columns in coal mines, as well as other hydraulic cylinders and columns. Its implementation standard is GB/T17396-1998. The production equipment for this type of steel pipe includes a Φ460 conical roller piercing machine and a PQF three-roll continuous pipe rolling unit with a limiting mandbar. It is capable of manufacturing large-diameter, thick-walled seamless steel pipes with specifications ranging from 245 to 457mm, with a designed production capacity of 500,000 tons.

Hydraulic prop tubes are widely used in hydraulic systems, plastic machinery, injection molding machinery, rubber machinery, forging machinery, die-casting machinery, construction machinery, the automotive industry, shipbuilding industry, metal processing, military industry, diesel engines, internal combustion engines, construction machinery, agricultural and forestry machinery, automation machinery, petrochemicals, aerospace, hydraulics and pneumatics, air conditioning, shoe-making machinery and other fields.

Hydraulic prop tubes are a type of steel pipe specifically used for hydraulic supports and cylinders, columns in coal mines, as well as other hydraulic cylinders and columns. Its implementation standard is GB/T17396-1998. Representative materials for hydraulic prop tubes include 20#, 45#, 27SiMn, 30CrMoSiA, etc. These materials are based on high-quality carbon structural steel, with one or several alloying elements appropriately added to enhance the steel's strength, toughness and hardenability.

This type of steel pipe usually needs to undergo heat treatment processes such as quenching and tempering, chemical heat treatment, and surface quenching to enhance its performance. Hydraulic prop tubes are mostly rolled into round, square or flat steel materials and are widely used as important structural components in machinery or machines. Although its anti-rust performance is not as good as that of stainless steel, it has better wear resistance and machinability.

The calculation method for hydraulic prop tubes is: [(outer diameter - wall thickness)* wall thickness]*0.02466=kg/meter (weight per meter). Hydraulic transmission has many advantages, such as light weight, small size, fast response speed, easy realization of stepless speed regulation and automatic control, etc. However, hydraulic systems also have some drawbacks, such as low efficiency, susceptibility to temperature, high manufacturing costs, and difficulty in achieving precise transmission ratios.

Hydraulic prop tubes are seamless steel pipes specifically designed for hydraulic systems. This type of pipe plays a crucial role in hydraulic systems, mainly used for transmitting hydraulic oil to ensure the normal operation of hydraulic equipment.The metallographic structure of the hydraulic prop pipe is ferrite + pearlite, which endows the pipe material with excellent mechanical properties and pressure resistance.

Hydraulic prop tubes are widely used in various mechanical equipment and industrial fields, including plastic machinery, injection molding machinery, rubber machinery, forging machinery, die-casting machinery, construction machinery, the automotive industry, shipbuilding industry, metal processing, military industry, diesel engines, internal combustion engines, construction machinery, agricultural and forestry machinery, automation machinery, petrochemicals, aerospace, hydraulic and pneumatic, air conditioning, shoe-making machinery, etc. These application fields have high performance requirements for hydraulic prop tubes, which need to have good pressure resistance, corrosion resistance and mechanical strength.

The advantages and disadvantages of hydraulics: The application of hydraulic prop tubes in hydraulic systems has significant advantages, but it also has certain limitations.

Advantages:

1. High flexibility: Various components in the hydraulic system can be conveniently and flexibly arranged as needed to adapt to different working environments and requirements.

2. Light weight and small size: The components of hydraulic systems are usually light in weight and small in size, which results in low movement inertia and fast response speed.

3. Wide speed regulation range: The hydraulic system can achieve a wide range of stepless speed regulation, with a speed regulation range of up to 2000:1, meeting the requirements of different working conditions.

4. Automatic protection function: The hydraulic system can automatically achieve overload protection, enhancing the safety and reliability of the system.

5. Long service life: As mineral oil is generally used as the working medium, the relative moving surfaces can self-lubricate, thus extending the service life of the system.

6. Easy to achieve automation: Hydraulic systems can easily realize linear motion, and when electro-hydraulic combined control is adopted, a higher degree of automatic control process can be achieved, and even remote control operation can be realized.

Hydraulic prop tubes are a type of pipe specifically designed for hydraulic systems, mainly used to transfer hydraulic oil and achieve motion control of mechanical equipment. The hydraulic system transmits power through the pressure energy of the liquid. As an important component of the hydraulic system, the performance of the hydraulic prop pipe directly affects the stability and efficiency of the entire system. Hydraulic prop tubes are usually made of high-strength alloy steel to ensure their reliability and durability under high-pressure conditions. Common materials include 10#, 20#, 35#, 45#, 16-50Mn, 27SiMn, etc. These materials have excellent mechanical properties and corrosion resistance, and can meet the requirements of different working conditions. The application scope of hydraulic prop pipes is very wide, mainly including the following aspects:

1. Mining machinery: In the mining processes of coal mines, metal mines, etc., hydraulic prop tubes are used to support the roof and ensure the safety of the working face.

2. Construction machinery: In the hydraulic systems of equipment such as excavators, loaders, and cranes, hydraulic prop pipes are used to transfer hydraulic oil and achieve the movement control of the equipment.

3. Industrial Equipment: In manufacturing, hydraulic systems are widely used in various machine tools, injection molding machines, die-casting machines and other equipment. Hydraulic prop tubes are used to connect components such as hydraulic cylinders and hydraulic motors to achieve precise motion control.

4. Marine Equipment: In the steering gear, anchor winch, and other equipment of ships, hydraulic prop pipes are used to transfer hydraulic oil, ensuring the smooth operation of the equipment.

5. Aerospace: In aerospace equipment such as aircraft and rockets, hydraulic systems are used to control components like landing gears and flaps. Hydraulic prop tubes need to have extremely high strength and reliability.

The selection and use of hydraulic prop tubes need to take into account multiple factors, including working pressure, temperature, medium properties, etc. Correct selection and maintenance can effectively extend the service life of hydraulic prop tubes and enhance the overall performance of the hydraulic system.
