Frequently Asked Questions

What is a hydraulic tube expander used for?

Hydraulic tube expanders are used to expand tubes into tubesheets in heat exchangers, boilers, and pressure vessels to create a leak-proof, mechanically strong joint.

Can your machines handle finned tubes?

Yes, our YC-150MPa finned water expansion machine is specifically designed for high-pressure expansion of finned tubes without damaging the fins.

Do you offer CNC-controlled expanders?

Yes, our electric numerical control pipe expanding machines offer programmable expansion parameters for consistent, automated results.

What power sources are available?

We offer single-phase 220V, three-phase electric models, and manual/hydraulic options for field use without power access.

What expansion medium should I use?

Water or a mixture of water and cutting fluid is recommended. Always ensure compatibility with your tube material.
