Processes

Making a quality forged flange involves several stages.

1. We procure raw material from approved sources. At time of delivery, we verify it against the purchase order, weigh it and confirm the heat code with mill certification. We run a PMI to authenticate alloys, then color code the material. QA reviews and approves all documentation before production.
   
   
2. When material is selected for a job, the billet is brought to the saw shop. One of our six computer-operated band saws, capable of cutting up to 26-inch diameter, cuts it to the specified length and weight.
   
   
3. The cut billet is heated in our furnace to its alloy-appropriate temperature, then forged using one of our four air-driven hammers. Traceability is maintained by hot stamping all parts.
   
   
4. In-house heat treating technology guarantees appropriate temperatures and hold times. All temperature controls are calibrated and certified.
   
   
5. Forgings that require a liquid quench are placed in our agitated, chiller-cooled quench tank, which is monitored by a chart recorder.
   
   
6. All parts are machined onsite to exact dimensions by expert manual and CNC machinists.
   
   
7. Traceability is maintained throughout the production process. Final marking includes material type, heat code and other pertinent information.
   
   
8. During inspection, calibrated instruments verify dimensions and surface finish. The marking is checked for accuracy and completeness.
   
   
9. Finally, each part is visually checked and carefully packed to protect against damage during transport.
