1、 Classified by pressure level

API petroleum hoses are classified based on the pressure level they can withstand, and common pressure levels include:

Low pressure hose: This type of hose is designed for low pressure applications and typically does not exceed 200 psi (pounds per square inch). Low pressure hoses are suitable for general industrial applications, such as the transportation of lubricating oil, water, and other non corrosive fluids.

Medium pressure hose: Medium pressure hose can withstand pressure between 200 and 1000 psi. This type of hose is suitable for the transportation of oil products, gases, and other industrial fluids under moderate pressure.

High pressure hose: High pressure hose is designed to withstand pressures exceeding 1000 psi, and can even reach thousands of psi. These types of hoses are commonly used in high-pressure oil wells, injection water, and other applications that require high-strength transportation pipelines.

 

2、 Classified by inner diameter size

API petroleum hoses are also classified according to their inner diameter size to meet different flow requirements:

Small caliber hose: usually refers to a hose with an inner diameter less than 1 inch. This type of hose is suitable for small-scale fluid transportation, such as measurement lines, chemical injection lines, etc.

Medium caliber hose: Hoses with an inner diameter between 1 inch and 4 inches belong to the medium caliber category. These hoses are commonly used for medium scale flow conveying, such as fuel lines, hydraulic systems, etc.

Large caliber hose: Hoses with an inner diameter exceeding 4 inches are considered large caliber hoses. They are used for large-scale fluid transportation, such as crude oil pipelines, large-scale irrigation systems, etc.

 

3、 Classified by application field

API petroleum hoses can be classified into the following categories based on different application areas and specific performance requirements:

Drilling hose: used in the process of oil and gas drilling, it needs to have extremely high wear resistance, pressure resistance, and high temperature resistance.

Floating oil hose: used for offshore oil extraction, it must have good flexibility and resistance to seawater corrosion.

Oil hose: used for the transportation of oil products on land or seabed, it needs to comply with corresponding pressure and chemical compatibility standards.

Chemical hoses: used for transporting corrosive chemicals such as acids, alkalis, etc., which require special chemical stability and resistance.

conclusion

API petroleum hoses can be classified into various specifications and types based on pressure rating, inner diameter size, and application field. Each type of hose has its specific design standards and performance characteristics to meet various complex requirements in the petroleum industry. Choosing the appropriate API petroleum hose is crucial for ensuring safe and efficient operations. When selecting hoses, not only should their specifications and types be considered, but also the properties of the fluid, working environment, and compatibility with the equipment. By understanding the different specifications and types of API petroleum hoses, users can choose the hose that best suits their specific application needs to optimize operational efficiency and safety.
