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.
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.
Tube Expanding Procedure Qualification Records (TEPQR) document what occurred during expanding the test specimen, the results of the testing, and the essential variables and other specific information identified for each process used.
Optimal Tube-to-Tubesheet Expansion Methods
Shopfloor covers multiple methods of tube expansion:
