Quality

As a supplier of pressure vessels constructed in accordance with Section VIII, Division I of the ASME Code, our experience dates back to 1968 when the company was issued the “U” stamp for unfired pressure vessels. JMW also has the “R” stamp for repairs to existing unfired pressure vessels.

Built-In Product Quality

Product quality must be built-in; it cannot be inspected, James Machine Works is committed to providing a product conforming to the highest level of quality specified or implied by our customers. This policy is implemented by rigid adherence to an approved and documented quality control system which is overseen by JMW’s quality management team.

Quality and production are synonymous. Quality control administration is completely independent of production expectations.

Proper order entry, engineering design, material procurement, design information, and inspection test plans are the requisite of quality management and product quality control. All such quality assurance is maintained within our organization, and is outlined in our formal and “working” Quality Control manual.

In-process inspection

In-process inspection with designated “hold” points is begun at start of fabrication and continues with production through completion. This inspection includes check of material verification, cutting, forming, fit-up, layout, and welding. Non-destructive examination is included during fabrication and upon completion. Multiple in-process inspections are performed. Magnetic particle, ultrasonic, and radiographic examinations are sub-contracted to third-party, qualified, and approved NDE companies and certified laboratories. Final dimensional and visual inspections are performed upon completion of fabrication by Quality Control inspectors. Pressure vessels constructed under the guidelines of the ASME Code are subjected to authorized third party inspection. JMW is presently contracted with the HSB, CT as the third party inspection agency.

Rigorous Testing

Upon completion of fabrication the vessel is subjected to a hydrostatic test. All testing is performed in accordance with Section VIII, Division 1 of the ASME Code. A vessel data sheet, Form U-1, is completed and signed off as meeting all Code compliances by the Quality Control Department and the authorized third party inspector. If surface preparation and painting is a requirement of the specifications, the vessel enters the painting facility to be grit blasted and coated per specifications. Environmental monitoring is conducted during the surface prep and coating application. Anchor profiles and millage readings are verified to NACE standards.
