In hydraulic systems, the seamless
pipe is key transmission component, and its material properties directly
affect the safety and efficiency of the system. According to different working
environments and application requirements, there are mainly the following types
of seamless pipes for hydraulic systems:
Carbon steel seamless pipes
1. #10 and # 20 steel seamless pipes
These two types of seamless pipes have
certain strength and good machinability, and the price is relatively
economical. They are widely used in general hydraulic systems and can withstand
medium pressure. For example, some small hydraulic equipment, machine tool
hydraulic systems, etc. often use # 20 steel seamless pipes as hydraulic
tubes.
2. # 45 steel seamless pipes
It has high strength and can be used in
hydraulic systems that withstand higher pressures. However, its welding
performance is relatively poor, and it is generally connected by threaded
connection or high-precision flange connection. It may be used in some medium and high-pressure hydraulic systems,
such as engineering machinery hydraulic systems.
Alloy steel seamless pipe
1. 15CrMo, 12Cr1MoV and other low alloy
high strength steel seamless pipes
It has high strength and good heat
resistance, suitable for high temperature and high pressure hydraulic systems.
For example, in the hydraulic systems of some large industrial equipment, such
as metallurgical equipment hydraulic systems, this type of alloy steel seamless
pipe may be used.
2. 35CrMo, 42CrMo and other medium carbon
alloy steel seamless pipes
It has high strength and good toughness,
and can withstand large loads and pressures. At the same time, it has good
hardenability and machinability. It is more common in some hydraulic systems
with high strength requirements, such as heavy machinery hydraulic systems. Its
manufacturing process is similar to that of mild
steel tube, but it is superior in strength and durability, and is suitable
for long sections and custom lengths of pipe installation.
Stainless steel seamless pipe
1. 304 stainless steel seamless pipe
It has good corrosion resistance, oxidation
resistance and processing performance. It is suitable for hydraulic systems
that require corrosive media, or for use in hydraulic equipment in industries
such as food and medicine. For example, in the hydraulic system of some food
processing machinery, 304 stainless steel seamless pipes are used to avoid food
contamination.
2. 316L stainless steel seamless pipes
It has stronger corrosion resistance,
especially in environments containing corrosive media such as chloride ions. At
the same time, it has good welding performance and low temperature performance.
It is widely used in hydraulic systems in marine engineering, chemical industry
and other fields.
Summary
When selecting a suitable seamless pipe for
a hydraulic system, various factors such as working pressure, temperature,
medium characteristics and installation method should be considered
comprehensively. Whether it is carbon steel, alloy steel or stainless steel
seamless pipe, each material has its unique advantages and applicable
scenarios. Reasonable selection can not only improve the safety and efficiency
of the system, but also provide solid guarantee for the long-term stable
operation of the equipment.
