Steel wire wrapped rubber tube 4SP4SH high-pressure oil pipe
In the modern industrial field, the stability and safety of hydraulic systems are crucial, and the quality of high-pressure oil pipes, as a key component of hydraulic systems, directly affects the operational efficiency and lifespan of equipment. This article will delve into the structural characteristics, application scope, and selection guidelines of steel wire wrapped rubber pipes 4SP and 4SH, helping you make informed decisions when choosing high-pressure oil pipes.
1、 Basic concept of steel wire wrapped rubber hose
Steel wire wrapped rubber pipes are commonly used to transport various liquids and gases, and their internal structure is often made of multiple layers of synthetic rubber and steel wire. The wrapped steel wire can effectively enhance the strength of the pipe wall, enabling it to withstand the working pressure in high-pressure environments. 4SP and 4SH are standard numbers for high-pressure oil pipes, representing different layers of wire winding and pressure levels, respectively.
1.1 Definition and Characteristics of 4SP
4SP refers to a high-pressure oil pipe wrapped with four layers of steel wire, suitable for transporting gases and liquids under high pressure. Its main features include:
-High pressure tolerance: can withstand working pressures up to 25MPa.
-High wear resistance: The combination of rubber layer and steel wire provides excellent wear resistance.
-Good flexibility: Despite its sturdy structure, the steel wire winding design maintains good flexibility during use.
1.2 Definition and Characteristics of 4SH
4SH represents high-pressure oil pipes wrapped with four layers of higher strength steel wires, suitable for fluid transmission under extreme working conditions. Its main features include:
-Higher pressure bearing capacity: capable of withstanding working pressures up to 32MPa, suitable for more stringent industrial applications.
-High temperature resistance: 4SH tubing has a wide operating temperature range and can work stably in high temperature environments.
-Excellent anti-aging property: the rubber material with special formula extends the service life.
2、 The main application areas of steel wire wrapped rubber pipes
2.1 Construction Machinery
In the field of construction machinery, the reliability of hydraulic systems is crucial. High pressure oil pipes, as the core component of hydraulic equipment, are widely used in heavy machinery such as excavators, cranes, and bulldozers. Choosing high-quality steel wire wrapped rubber pipes can effectively reduce failure rates and improve work efficiency.
2.2 Agricultural Machinery
With the continuous improvement of agricultural mechanization, high-pressure oil pipes also play an important role in agricultural equipment. Steel wire wrapped rubber pipes that can withstand high pressure and wear are widely used in irrigation systems and fertilization equipment to ensure the sustainability and stability of agricultural production.
2.3 Chemical Industry
In the chemical industry, many special liquids need to be transported through high-pressure oil pipes. Steel wire wrapped rubber pipes can adapt to various chemical media, especially 4SH oil pipes, and can operate stably under high temperature and high pressure, ensuring the safe transportation of chemical products.
2.4 Energy sector
High pressure oil pipes also play an indispensable role in the extraction and transportation of oil and natural gas. Due to extreme working conditions such as high pressure and corrosion during the mining process, selecting high-quality steel wire wrapped rubber pipes is a necessary condition to ensure safety and efficiency in the energy transmission process.
3、 Guide to Choosing High Pressure Oil Pipes
3.1 Determine the usage environment
When selecting high-pressure oil pipes, it is necessary to first have a detailed understanding of their operating environment, including working temperature, pressure, and type of medium. These factors directly affect the selection of oil pipes. For example, in high-temperature environments, 4SH tubing is clearly more suitable, while 4SP can be considered for the opposite.
3.2 Checking Product Certification
Choosing the right supplier is crucial. Ensure that the purchased steel wire wrapped rubber pipes have corresponding international or domestic standard certifications, such as ISO9001, to ensure product quality and performance.
3.3 Performance parameter comparison
Before purchasing, compare the performance parameters of several different brands and types of high-pressure oil pipes, and select the appropriate product based on their pressure resistance, temperature resistance, chemical resistance, and price information.
3.4 After sales service considerations
When choosing high-pressure oil pipes, attention should also be paid to after-sales service. High quality after-sales service can effectively help users solve problems encountered during use and ensure the normal operation of equipment.
4、 Maintenance and upkeep
4.1 Regular Inspection
Regular inspection of steel wire wrapped rubber pipes is an important step to ensure their normal operation. Attention should be paid to checking the pipe wall for wear, cracks, aging, and other conditions. If any problems are found, they should be replaced in a timely manner.
4.2 Avoid direct exposure to high temperatures
Try to avoid placing high-pressure oil pipes in direct high-temperature environments to prevent rubber material aging and affect their service life.
4.3 Maintain cleanliness
Maintain the cleanliness of the oil pipe to prevent external contaminants from entering, reduce corrosion inside the pipe, and also improve the efficiency of liquid transportation.
4.4 Reasonable storage
When not in use, the high-pressure oil pipe should be stored properly and kept coiled as much as possible without being compressed to avoid rubber deformation or damage.
5、 Summary
Steel wire wrapped rubber hose 4SP/4SH has a wide range of applications in multiple industries, and has become an indispensable part of modern mechanical equipment due to its excellent pressure bearing capacity and wear resistance. Understanding its characteristics, application areas, and maintenance during the selection and use process is an important factor in extending its service life and ensuring safe operation.
