Expander
Frequently Asked Questions
What is the primary function of an expander?
An expander is designed to enlarge the diameter of tubes, pipes, or ducts to create a secure, precise, and leak-proof joint connection. It is widely used in plumbing, HVAC, and industrial manufacturing systems.
How does a mechanical tube expander operate?
It operates by inserting the expander head into the tube end. When force is applied (manually, hydraulically, or pneumatically), the expanding segments push outward uniformly against the inner wall, expanding the material to the desired fit.
What materials are compatible with expander tools?
Expanders work best on malleable and ductile metals such as copper, aluminum, brass, soft steel, and certain grades of stainless steel that can undergo plastic deformation without cracking.
How do I choose the correct expander size?
You should select an expander based on the nominal tube size, outer diameter (OD), inner diameter (ID), and wall thickness (gauge) of the tubing material you plan to expand.
What maintenance is required for expander tools?
Keep the expander head clean of metal shavings and debris, regularly apply high-quality lubrication to the moving parts, and store the tool in a dry environment to prevent corrosion.
