Double Tube Sheet Tube Expander

S-14

S-9 Boiler Thick Drum Tube Expander_edit

Full Description

The Double Tube Sheet Tube Expander is intended for tube expansion in double-tube-sheet arrangements. The legacy catalogue highlights the need to inspect and record tube-sheet-hole dimensions, clean tube and hole surfaces before insertion, and qualify the tooling and expansion parameters using a mock-up or trial block. Parameters such as expander type, drive arrangement, and torque-control setting should be established for the specific job and kept consistent during production unless an approved procedure requires a change.

Key Features

For double-tube-sheet applications; emphasises dimensional inspection and surface preparation; supports mock-up qualification; process parameters should be documented and controlled; application-specific tooling selection.

Technical Specifications

Product code: S-14; application: double tube-sheet tube expansion; qualification: trial block/mock-up recommended as described in legacy material; parameters include expander type, drive arrangement and torque-control setting; tube size, sheet spacing, materials and acceptance criteria: to be confirmed.

Applications

Double-tube-sheet heat exchangers; specialised tube-sheet joints; project-specific expansion and maintenance work.
