Tube Expander P-1000 Series
Follow the link below for the full PDF specifications:
- Tube Joint formed by compressing the tube into a fixed container (i.e. tube sheet).
- Ideally rolled joint is created when the tube’s state turns to plastic (stays where it stops) and is contained by the tube sheet’s elastic properties (fully recovers). This must occur right before the tube sheet turns to a plastic state.
- Under-rolling occurs when the tube is not compressed enough and remains at an elastic stage. A bond is not created as the yield of the material is not compressed enough to turn the tube sheet into an elastic material.
- Over-rolling occurs when the tube surpasses the elastic property of the tube sheet and therefore the ligaments between the tube sheet holes are shifted, causing adjacent tubes to leak.
Proper Operation for Effective Joints and Tool Life
- The tube surfaces must be clean of debris, scratches, dents, cracks, and any other imperfections of the tube.
- Inspect the tube sheet for any radial or longitudinal imperfections.
- Lubricate the expander with a water-based lubricant.
- Insert the tube expander into the tube and connect the drive being used.
- From the chart below, roll the tube until the correct ID is achieved.
Roll ID Calculation
Uses:
When using the tube expander P-1000 series, they’re often used in conjunction with the P-3000 for rolling thick tube sheets, where the tube sheet can be up to 5.3/8″ thick.
The ideal tube expander for boilers.
Advantages of the P-1000 Series Tube Expanders:
A flaring expander that is ideal for use in limited-access areas, for example, water boxes and small mud and steam drums.
