case study

CUSTOMER:Kiewit
‍LOCATION:Tampa, FL, USA
‍MATERIAL:A516-70N

challenge

The tube sheet was 1.5” thick on A516-70N material with only localized preheat available during execution.

This created a high risk of cracking as welds cooled, making it difficult to achieve consistent, defect-free seal welds using conventional methods.

results

Utilizing Liburdi Dimetrics’ P450 tube sheet weld head, Liburdi GAPCO successfully completed the seal welds under controlled localized preheat conditions. The approach ensured weld integrity and eliminated cracking concerns, restoring reliable sealing performance.
