QA/QC is conducted on a job by job basis as all work we perform is custom work. Below are the QA/QC program steps.

Pre-planning of work - The program will start by meeting with our customer's representatives or engineers to discuss equipment design, metallurgy, design pressure/vacuum limits, cleaning and plant effluent handling requirements. Then Delta Tech will submit detailed, step by step, procedures including drawings, indicating system pre-cleaning inspection, mechanical setup, chemical cleaning procedures and documentation, post cleaning inspection and lay-up procedures for approval.

Cleaning of systems - Once the procedures have been approved, the actual cleaning will be documented using a time and initial format indicating the date and time as each step is completed. If in process inspections are required, there will be sections that will be completed indicating who inspected the work in progress and when it was inspected.  Should conditions or the scope of the project change, requiring a change in procedure, the Delta Tech Supervisor will submit the proposed changes in writing to the customer's representative for approval.

Post cleaning inspection and review - At the conclusion of the cleaning operations, inspections will be performed by the Delta Tech QA/QC supervisor and customer's representative to insure that the work was completed as expected.    Delta Tech will submit a letter of completion with the detailed procedures and equipment sign-off sheets to customer's representative for retention.

This system of QA/QC has been developed and proven to be effective over 30 years.
