What is the difference between rotary joints and pipeline connections

There are significant differences between rotary joints and pipeline connections in multiple aspects. The following is a detailed analysis of the differences between the two:

Definition and Function:

Rotary joint: It is a pipeline connecting device that can achieve relative rotation of connected pipelines, mainly used for conveying various media such as gas, liquid, oil, etc. It is a closed rotary connector for 360 ° rotating conveying media, with a compact design structure that is effectively integrated into customer equipment through flange connections.

Pipeline connection: refers to the process of connecting prefabricated pipe sections into a complete system according to the requirements of the design drawing. It involves multiple connection methods, such as threaded connection, flange connection, welding connection, etc., and the specific selection depends on the material of the pipe used.

Application features:

The main focus is on how to connect pipe sections into a complete system to meet specific fluid transport needs.

The choice of connection method depends on the material of the pipe, such as ordinary steel pipe, seamless steel pipe, cast iron pipe, plastic pipe, etc.

Suitable for various pipeline connections, including liquid, gaseous, and paste conveying pipelines.

It can connect pipelines of various materials and is widely used in transportation pipeline systems in industries such as chemical, petroleum, and natural gas.

Mainly used to input liquid from this side of the pipeline into rotating or reciprocating equipment, and then discharge it from it.

Rotary joint:

Pipeline connection:

Structure and composition:

Rotating joint: usually composed of flange, sealing gasket, and rotating parts, with a relatively simple manufacturing process.

Pipeline connection: Depending on the selected connection method, its structure and composition may vary. For example, flange connections involve two flange plates, flange gaskets, and bolts, among other components.

Installation location and purpose:

Rotary joint: gene
