Pressure Vessels and Heat Exchangers
Our capabilities in pressure vessel and heat exchanger technology encompass the following areas, among others:
- Design evaluations
- Compliance with ASME Code and specification requirements
- Development of technical purchase specifications
- Design details for high temperature, internally lined equipment
- Engineering design details
- Catalyst support grids
- Plenum chamber and cyclone systems
- Fluidized solids distribution grids
- Hot/cold nozzle intersections
- Support skirt intersections
- Outlet collectors
- Rerating and repair analysis
- Tall vessel design
- Wind
- Earthquake
- Process- or wind-induced vibration
- Shell-and-tube heat exchangers
- Flange leakage
- Vibration evaluation
- Heat transfer duty
Here are a few examples of assignments related to pressure vessel and heat exchanger technology that we have successfully completed:
- Evaluated existing pressure vessels and heat exchangers for revised design conditions. Demonstrated that vessels were acceptable without changes.
- Analyzed locally corroded regions of an existing pressure vessel. Demonstrated that the vessel was acceptable for unrestricted operation.
- Reviewed vendor design of large, horizontal pressure vessel intended for hazardous waste storage. Found major errors in saddle support design and in minimum temperature limit for use.
- Developed mechanical design purchase specification for a large high-temperature steam generator. Performed bid conditioning review of vendor design and participated in vendor selection.
- Performed design analysis of cyclone plenum systems for vessels containing fluidized solids. Initiated changes to vendor-proposed design to adequately carry design loads.
- Designed and prepared stress analysis of distribution grids for large, fluid-solids unit vessels. Prepared design specifications for vendor quotation.
- Prepared failure evaluation of distribution grid supports in fluid-solids unit vessels.
- Gave onsite turnaround assistance in inspection and evaluation of fluid-solids unit vessels.
- Analyzed reactor outlet collectors to determine acceptable differential pressure to avoid a unit shutdown.
