Tube-to-Tubesheet Expansion in Shopfloor

Sealing tubes is an essential part of any shell-and-tube heat exchanger manufacturing process, and there are various considerations to make when determining the best tube-to-tubesheet expansion methods.

Shopfloor includes tube expanding procedures and qualifications from Nonmandatory Appendix HH of ASME VIII-1 which establishes the requirements for procedure specifications for expanded tube-to-tubesheet joints.

Compliance, Precision, Quality

Ensure compliance, achieve precision, and improve quality using Shopfloor’s ASME VIII forms. The tube-to-tubesheet expansion forms available in Shopfloor include TEPSs and TEPQRs.

TEPS

Tube Expanding Procedure Specifications (TEPS) provide the tube expander operator with instructions for making production tube-to-tubesheet joint expansions in accordance with Code requirements.

Optimal Tube-to-Tubesheet Expansion Methods

Shopfloor covers multiple methods of tube expansion:

  • Explosive – the tubes are expanded with the force of an explosion.

  • Roller – the tubes are expanded via a tube-rolling tool, or a mandrel.

  • Hydraulic (hydroexpanding) – the tubes are expanded by hydraulic pressure.

  • Hybrid – a two-step process using a combination of the above expansion technologies.
