TEMA
• The Tubular Exchanger Manufacturers Association, or TEMA, is a group of leading
manufacturers who have pioneered the research and development of heat exchangers
since 1939.
• It’s not easy for manufacturers to become a TEMA member. It takes more than just
purchasing a standards manual. Member companies must meet stringent criteria and
adhere to strict specifications to qualify for TEMA membership.
–must have in-house thermal and mechanical design capabilities, and thoroughly understand current
code requirements and initiate strict quality control procedures.
–Additionally, all welding must be done by the company's own personnel, and the company must
have its own quality control inspectors.
• TEMA members develop and update today's standards.
SHECO – A proud member of TEMA for more than 20 years.
HTRI
• HTRI, the world-recognized leader in heat transfer, has been running its applied research program since 1962
• They conduct real-world, applied research on near full scale test units
• Utilize computational fluid dynamics (CFD) and laser anemometry visualization
• The largest concentration of heat transfer expertise in the world

Continuous Improvement
• 6S Program
• Quality at the Source
• Quality Audit System
• Production Control Management System
Continuous Improvement
• 6S Program - Sort, Set, Shine, Standardize, Sustain plus Safety– Shadow boards in place plant-wide
– Improved Material Flow by setting up designated holding areas
– Resulted in dramatic improvement in complex changeovers on the VTL Machine Center
Continuous Improvement
• Quality at the source
–Never start the next operation before checking the incoming part for defects
–Check each process before starting work (safety, prints, equipment setting, checklists etc.)
–Check work during operations at critical points in the process
–Stop work until the issue is corrected
–Check work after complete
–Never pass a part to the next operation if defective
• This has reduced QC Inspection time by 30%. QC Inspectors now have 30% more time
each day to assist with process improvement, training and permanent problem
resolution.
• We’re driving defects inspectors catch from >15% to <5% and soon less than 1%.
Continuous Improvement
• Quality Audit System
–Level 1 Audits
•Quality at the source. Occur throughout the day as part of our standard operations. Conducted by
Supervisors, Team Leaders and Operators.
–Level 2 Audits
•Quality inspectors inspect work at key intersections before allowing parts to pass to the next
operation. No supervisor can override an inspectors decision to hold work.
–Level 3 Audits
•Conducted randomly, at least weekly, by senior management.
–Level 4 Presidential Audit
•Conducted randomly throughout the month.

Customer Specifications
• How do we know SHECO employees know and understand Customer Specifications?
–Step 1: Management Team created to review and incorporate Customer Specifications with SHECO
shop practices and procedures (as needed).
–Step 2: Create Process Workflow Checklist for shop supervision.
–Step 3: Create Shop Floor Work Instructions to support the Process Workflow Checklists.
–Step 4: Train the shop supervision on the use of Process Workflow Checklists.
–Step 5: Provide shop floor access to these Work Instructions and Customer Specifications.

Work Flow Documentation and Instructions
• SHECO uses Work Flows and Work Instructions to communicate to the shop for all
processes for both SHECO standards and customer specific requirements.
• After critical customer specific Work Flows and Work Instructions are developed, we map
SHECO standard work to create our SHECO Work Flows and Work Instructions.
• All SHECO standards and customer specific Work Flows, Work Instructions, and
customer specifications are available for all shop supervision and workers on the floor
using electronic kiosks .
• This is a continuous improvement process that will evolve as needed to meet the
changing needs of our customers.
