Cone Rolling Tube Expanders

S-15

S-9 Boiler Thick Drum Tube Expander_edit

Full Description

Cone Rolling Tube Expanders are intended for tube-to-tubesheet applications where the tube end must be positioned and expanded to support the required joint preparation. The legacy catalogue describes use where tube-end fit-up is needed before welding, with the tube end centred and uniformly brought into contact with the tube-sheet hole. Cone rolling may help prepare the joint for subsequent welding when used in accordance with the approved procedure. Confirm the correct tooling and joint design before use.

Key Features

Cone-rolling design; supports tube-end fit-up; intended to help achieve centred, uniform contact in suitable applications; can support weld preparation where specified.

Technical Specifications

Product code: S-15; method: cone rolling; application: tube-to-tubesheet fit-up and selected weld preparation; tube OD, wall thickness, tube-sheet-hole dimensions, material and operating parameters: to be confirmed.

Applications

Tube-to-tubesheet joint preparation; selected heat exchanger and boiler work; preparation before tube-end welding.
