A cold expanding tool is a specialized device for processing pipes or pipe fittings, primarily used to flare pipe ends at room temperature to facilitate connection or installation of other components.
Flaring: Expand the pipe end into a flared (bell-mouth) shape for easy connection or sealing with other pipe fittings.
Forming: Ensure the flared end is uniformly shaped and smooth, preventing cracks or deformation.
Sealing Enhancement: The flared pipe end enables better fitting with joints, improving overall sealing performance.
Select the right specification: Choose a flaring tool matching the pipe's diameter and material.
Secure the pipe: Clamp the pipe firmly to ensure stability during operation.
Install the flaring die: Mount a die that is compatible with the pipe's specifications.
Perform flaring: Drive the die into the pipe end via rotation or hydraulic pressure to complete the flaring process.
Quality inspection: Verify that the flared end is uniform in shape and free of cracks.
Ensure the pipe material is suitable for cold flaring processing.
Clean the pipe end before flaring to remove impurities that may affect quality.
Control the flaring force to avoid excessive deformation or pipe damage.
As an essential tool in pipe processing, proper use of a cold expanding tool enhances work efficiency and connection reliability.
