A cold expander–flaring tool is a specialized device used for processing pipes or pipe fittings, primarily to flare pipe ends at room temperature for easier connection or installation of other components.
Main functions of the cold expander–flaring tool:
Flaring: The pipe end is expanded into a flared shape to facilitate connection with other fittings or sealing.
Forming: Ensure that the flared shape is uniform and smooth, avoiding cracks or deformation.
Improved sealing: The flared pipe end fits more tightly with the fitting, enhancing the seal.
Specifications: 1/4, 3/8, 1/2, 3/4, 1"

Usage steps:
Select the appropriate size: Choose an expander that matches the pipe’s diameter and material.
Fixed piping: Clamp the pipe to ensure stability.
Install the flaring die: Select a flaring die that matches the pipe.
Flaring: The die is pushed into the tube end by rotary or hydraulic actuation to complete the flaring process.
Quality inspection: Ensure the flared shape is uniform and free of cracks.
Precautions:
Ensure that the pipe material is suitable for cold-flaring.
Clean the pipe ends before flaring to prevent contaminants from compromising quality.
Control the flaring force to prevent excessive deformation or damage to the pipe.
A cold expanding tool is an essential instrument in pipe fabrication; proper use can enhance work efficiency and connection quality.
