Half Coupling has the same radius as the pipe, securing only half of the pipe and bearing a relatively lower load. It is typically used for low-pressure, low-temperature, and small-diameter pipeline connections, such as household water supply pipes and natural gas pipelines.

Difference between Half and full couplings
Functional Differences Between Half Pipe Couplings and Full Pipe Couplings
Both half pipe couplings and full pipe couplings are pipeline connection components, primarily used to join two pipes. The half pipe coupling matches the pipe's radius, while the full pipe coupling can connect pipes of different radii. Additionally, since the half pipe coupling only secures half of the pipe, it bears relatively less load compared to the full pipe coupling.
Installation Methods
Installing a half pipe coupling requires aligning the pipe before bolting the coupling in place, necessitating precise alignment by workers and making the installation process more complex. In contrast, full pipe couplings are easier to install and offer superior air tightness and connection strength.
Application Scenarios
Half pipe couplings are typically used for low-pressure, low-temperature, and small-diameter pipelines, such as household water supply or natural gas pipes. Full pipe couplings have broader applicability, suitable for high-pressure, high-temperature, and large-diameter pipelines, including chemical plants and wastewater treatment systems.
Selection Guidelines for Pipe Couplings
- Installation Conditions: Choose couplings based on spatial constraints and accessibility.
- Operating Parameters: Select couplings that meet the pipeline's pressure, temperature, and medium requirements.
- Pipe Diameter: Match the coupling size to the pipe diameter.
- Material Compatibility: Ensure the coupling material is compatible with the pipe material.
- Environmental Resistance: Opt for corrosion-resistant or wear-resistant couplings for harsh environments.
