Boiler Thick Drum Tube Expanders

S-9 Boiler Thick Drum Tube Expander_edit

Full Description

Boiler Thick Drum Tube Expanders are intended for applications where boiler drum tube sheets are thicker than standard rolled sizes. The legacy catalogue describes progressive expansion operations based on tube-sheet thickness and notes that a combination of expander types may be used to meet the required expansion across the tube-sheet depth. Final tooling selection and process parameters depend on the tube and tube-sheet dimensions, material, and joint requirements.

Key Features

Designed for thicker boiler-drum tube sheets; supports progressive expansion operations; tooling combination may be selected for the required expansion depth; application-specific process planning.

Technical Specifications

Product code: S-9; application: boiler thick-drum tube expansion; legacy catalogue references expansion across thicker tube sheets and a possible overlap of 1/4 inch or 5–6 mm between progressive operations; confirm values against the approved procedure; tube dimensions and tooling configuration: to be confirmed.

Applications

Boiler drums; thick tube-sheet expansion; boiler maintenance and tube replacement projects.
