Pressure vessel guide for vertical industrial vessels, process storage, ASME-style review, material selection, inspection scope, and RFQ preparation.
Pressure vessel RFQs must define design pressure, temperature, media, material, code basis, nozzles, inspection, and document requirements.
Pressure Vessels for Industrial Process Systems
Pressure vessels are not ordinary atmospheric storage tanks. They must be reviewed by design pressure, temperature, stored media, material, corrosion allowance, nozzle loads, safety devices, welding, NDT, and code requirements.
Many projects reference ASME Section VIII for pressure vessel design, but the final code basis must come from the owner specification, jurisdiction, and process engineer. This page helps buyers separate pressure-vessel data from normal tank RFQs.
Pressure Vessel RFQ Data
Review Item
Recommended Buyer Input
Design conditions
Design pressure, operating pressure, design temperature, operating temperature, vacuum condition if any, and cyclic service.
Media/material
Stored/process media, corrosion data, stainless or carbon steel preference, lining/coating if needed, and cleaning method.
Code and inspection
ASME Section VIII or project code basis, NDT, hydrotest/pneumatic test, third-party inspection, and document package.
Mechanical details
Vertical or horizontal vessel, diameter/length, nozzles, manways, supports, platforms, safety valves, instruments, and skid interface.
When to Use a Pressure Vessel Page
Use this page when the system operates above atmospheric storage conditions or when the process engineer specifies a pressure boundary. For atmospheric tanks, use welded steel tanks or bolted storage pages instead.
Because pressure vessels require stricter documentation, buyers should send inspection and certificate requirements with the RFQ rather than after the order is placed.
