Landmark’s 1st custom forming project without pre-fitting

Contract Fabricators, Inc. required a large diameter ASME Code Hemispherical Head for a fluid catalytic cracker assembly at a Valero Refinery. 

Project timing constraints did not allow typical pre-fitting at our fabrication facility, and exacting tolerances were specified.

Landmark designed a new fabrication process to eliminate pre-fitting and guarantee proper forming and fit during assembly at the client’s shop.

Operational Highlights:

  • Landmark quality management and steel fabrication teams were utilized to perform a high level of QA/QC inspections, and test planning.
  • Project tolerances were met with no rework required.
