Tube Expander – 800 SERIES
SAPSONS 800 Series Tube Expander is a precision mechanical tool used for expanding tubes into tube sheets in heat exchangers, condensers, boilers, and other industrial equipment. Its roller-type expansion mechanism uniformly enlarges the tube against the tube-sheet hole, creating a strong and leak-resistant joint. The tool is valued for its reliability, durability, and suitability for general tube installation and maintenance applications.
Description
The 800 Series is designed primarily for medium-size tubes used in heat-transfer and industrial equipment. The expander uses a rolling mechanism in which rollers are driven against the inside wall of the tube. As the tool rotates, the rollers expand the tube uniformly against the tube sheet.
It is suitable for applications such as:
- Heat exchangers
- Condensers
- Boilers and pressure vessels
- Oil coolers
- Chillers and HVAC equipment
- Feedwater heaters
- General industrial tube installation and maintenance
The series is available with different roller lengths and configurations to suit the required tube expansion depth.
Working Principle
The tube expander is inserted into the tube and driven by a suitable rotating drive. The internal rollers rotate and press against the tube wall, causing the tube to expand outward into the tube-sheet hole. This controlled expansion produces a firm mechanical fit and helps prevent leakage.
