Air Receiver Vertical 120-500 Gallons
- Designed and constructed in accordance with ASME Section VIII Div-I Code for compressed air storage use.
- "U" stamped and registered with the National Board of Pressure Vessel Inspectors.
- Most designs include Canadian Registration Numbers (CRN).
- Capable of building to American Bureau of Shipping (ABS) and United States Coast Guard (USCG) codes.
- Custom engineered designs available upon request.
- Exterior surface painted with one coat standard shop primer.
- Special exterior and interior coatings available upon request
- There should be at least one high quality pressure indicating device attached directly to an opening in the vessel.
- A relief valve must be selected and installed. The valve must be sized according to the maximum flow rate into the vessel such that over-pressurization cannot occur. See ASME Section VIII, Division 1, Paragraph UG-125 for details on relief valves.
- An automatic drain device is recommended to regularly drain any condensate from the vessel. In lieu of an automatic device, the user should be cautioned to regularly drain the receiver manually.
- Notes: Reinforced concrete 28 day ultimate strength – 2500 psi minimum
- Uniform gravel and soil base beneath footing. Footing surface shall be flat and level in all directions.
- Anchoring the vessel to the concrete footing is necessary to stabilize the receiver only and is not intended to provide resistance against wind, seismic, or other external loadings that may create a vessel tipping condition. The table below represents footing depths for compressive loading only.
- Check local construction codes, fire codes, or building standards.
- Use an appropriately sized anchor bolt of SA-325 material or better, a wrought steel washer, and a heavy hex nut.
- Footings exposed to freezing temperatures should be sufficiently sized in depth to prevent cracking.
- Larger vessels not covered in the table, saddles may be provided which have holes on one end of the vessel and slots on the other end of the vessel. When bolting saddles to the foundation, anchor bolting should be fixed by first hand-tightening the nut and then locking the threads by staking, double nutting, or tack welding.
Maintaining a pressure vessel includes proper inspection. Many states have adopted the National Board Inspection Code (NB-23) for rules concerning post-construction activities. Check with your local authorities having jurisdiction over pressure vessel installations and operations for any additional requirements concerning in-service inspection.
