Overview of Common Joint Types And Applications

The types of connectors are very diverse and widely used in various industrial fields. Here are some common types of connectors, their characteristics, and application scenarios:

1. Welding joints

a. Docking welding

Characteristics: Welding is carried out at the junction of two welding materials, with high welding strength, suitable for thicker materials such as steel plates, steel pipes, etc.

Application: Commonly used for connecting structural components such as bridges, buildings, ships, etc.

b. Corner welding

Characteristics: Welding at corners, suitable for high-pressure pipeline systems such as natural gas pipelines, oil pipelines, etc.

Application: Commonly used for connecting pipeline systems and structural components that require significant stress.

c. Circumferential welding

Characteristics: Welding is carried out in a circular or ring-shaped manner, suitable for pipeline systems that transport liquids or gases.

Application: Commonly used in the manufacturing and maintenance of pipeline systems, such as in industries such as petroleum, chemical, and natural gas.

d. Socket welding

Characteristics: A welding method that inserts two welded parts, suitable for connecting thin plates, and is also divided into single-sided welding and double-sided welding.

Application: commonly used for connecting pipelines and equipment, such as water pipes, air pipes, etc.

e. Edge welding

Features: Connecting two materials together by curling, simple and easy to implement.

Application: Suitable for situations that require quick connection, such as the construction of temporary facilities.

2. Threaded joint

a. Features: Two workpieces are connected by threads, which are tight and not easy to loosen.

b. Classification: Divided into two types: internal thread and external thread.

c. Application: Commonly used for connections in pipeline systems, as well as occasions that require frequent disassembly and maintenance, such as water pipes, air pipes, heating pipes, etc.

3. Card sleeve connector

a. Features: The connection material is firmly clamped by a sleeve, suitable for connecting low-pressure pipeline systems and conveying liquid or gas systems that do not contain corrosive substances.

b. Application: Commonly used for connecting low-pressure piping systems, such as water pipes, air conditioning pipes, etc.

4. Flange joint

a. Features: Two flanges are fixed to each other by bolts to complete the connection, suitable for pipeline connections in industries such as food and medicine.

b. Application: Commonly used in applications that require high sealing, such as chemical, petroleum, pharmaceutical and other industries.

5. Quick connector

a. Features: Used for quick connection and disconnection of pipes, including steps such as inserting pipes, verifying connection firmness, placing snap rings, etc., to ensure the sealing and stability of the connection.

b. Classification: including quick plug connectors, quick twist connectors, C-type self-locking quick connectors, etc.

c. Application: Commonly used in situations that require frequent connection and disconnection, such as hydraulic systems, pneumatic systems, cooling systems, etc.

6. Other connectors

a. Pagoda joint: commonly used in pneumatic and hydraulic systems, it has the characteristics of simple structure and easy installation.

b. Expansion joint: Connecting pipes and joints through expansion process, suitable for high-pressure pipeline systems.

c. Collar joint: Fixing the pipeline to the joint through a collar, suitable for low-pressure pipeline systems.

In summary, there are various types of connectors, each with its specific application scenarios and advantages. When selecting joints, it is necessary to comprehensively consider factors such as specific engineering requirements, pipeline parameters, and medium characteristics.
