KRAIS Tube Expanders
This channel presents our tools and machines used in tube and pipe industry. We show how they work in real conditions: heat exchangers, air-cooled fin fan coolers, boilers, condensers, and other process installations. Each video focuses on practical operation — from tube preparation and cleaning to machining, sealing, and inspection.
You will find:
- demonstrations of tube preparation before plugging,
- installation and removal of T_APPL mechanical tube plugs (HEP and FFP series),
- tools designed for hard-to-reach fin fan areas,
- cutting, bevelling, rolling, and expansion tools,
- on-site and workshop solutions for maintenance teams.
The content is created for engineers, technicians, and maintenance specialists who expect reliable, precise, and repeatable tooling. If you work with heat exchanger service, shutdown operations, tube repair, or fabrication, these videos provide straightforward, practical insight into how our tools perform in the field.
