Silvan Industries 1054 Tank

Is this ASME or DOT rated, and what does that allow me to do with it?

This is an ASME-rated pressure vessel. ASME certification qualifies it for stationary installation at your facility under the Boiler and Pressure Vessel Code, covering fixed storage, process vessels, and other non-transport applications where jurisdictional authorities accept Section VIII construction.

What is the MAWP and capacity at service pressure?

The maximum allowable working pressure is 150 PSIG at 450°F, with a minimum design metal temperature of -20°F at 150 PSIG. The listing does not specify vessel capacity or dimensions—ask the seller for total volume, orientation (horizontal/vertical), and overall dimensions to confirm it meets your process requirements.

What is the requalification or inspection status?

The listing does not indicate whether the vessel has current external inspection, thickness testing, or relief valve certification. ASME vessels in stationary service typically follow the jurisdiction's inspection interval (often annually or biennially depending on service and local code), so request documentation of the most recent authorized inspector examination and any thickness survey data before acquiring.

What should I inspect before putting it into service?

Verify the data plate is intact and legible, then inspect for corrosion, dents, or distortion that could compromise shell integrity—especially at nozzles, supports, and the bottom head if the vessel saw condensing service. Check all openings and flanges for thread or sealing surface damage, confirm relief valves are present and within test date, and review the vessel's prior service history to ensure material compatibility with your intended contents. For vessels approaching or exceeding their original design life, ultrasonic thickness testing at representative locations is standard practice before returning to service.
