What are the connection methods of compression elbows and what are their characteristics?

Compression elbows are important connecting components in pipeline systems and have various connection methods.

1. Welding connection
Features: The weld has high strength, which can ensure the stability and safety of the pipeline system.
Good tightness and not prone to leakage.
Relatively low cost because no additional connection accessories are required.
Once the welding is completed, it is not easy to disassemble, so it is not convenient for pipeline maintenance and replacement.
Applicable scenarios: Suitable for steel pipeline systems that transport various media.
Especially suitable for pipeline systems that need to withstand high pressure, high temperature or corrosive media.

2. Flange connection
Features: Flexible and convenient disassembly and assembly, convenient for pipeline maintenance, inspection and replacement.
Applicable to medium and high pressure occasions, able to withstand certain pressure and temperature fluctuations.
Requires flanges and bolts of various specifications and other accessories, and the cost is relatively high.
The connection may leak due to temperature difference, pressure fluctuation and corrosion.
Applicable scenarios: Suitable for pipeline systems that need to be cleaned, repaired or replaced regularly.
Applicable to pipeline systems that need to be frequently disassembled and connected.

3. Threaded connection
Features: Easy operation and fast installation. Easy to disassemble and repair. Relatively poor sealing, leakage may occur. Applicable to pipeline systems with smaller diameters.
Applicable scenarios: Suitable for elbow connections with smaller diameters.
Applicable to low-pressure piping systems such as production or domestic water, heating facilities, etc.

4. Socket connection
Features: Easy installation and low cost. Applicable to occasions with low pressure and large diameter.
The sealing may be affected by the installation quality, and the sealing needs to be ensured during the installation process.
Applicable scenarios:
Applicable to piping systems with larger diameters and lower pressures.
Applicable to occasions with certain requirements for installation speed and cost.

5. Clamp connection
Features: Quick connection, no need for professional technology and tools. Good reusability, easy to disassemble and replace. May not withstand extremely high pressure, suitable for low and medium pressure occasions.
Applicable scenarios:
Applicable to piping systems that require quick connection and disassembly.
Applicable to occasions with low pressure requirements.
