For this installment of our Equipment Expertise post, we wanted to focus on another piece of equipment that can be found in manufacturing plants and labs around the world. Vessels come in all shapes and sizes, jacketed and non-jacketed, stainless steel, carbon steel, glass–lined, and hastelloy. These seemingly simple instruments can be tricky to inspect, since just one hairline crack, invisible to the naked eye, could indicate years of repairs, delays, and headaches to come.
So, in order to provide our customers with the most accurate information, we have spoken to EquipNet’s in-house engineers and equipment specialists to gather details about how to perform a successful inspection of a vessel before committing to a purchase. We’ll start off focusing on pressurized and non-pressurized, jacketed and non-jacketed, glass-lined vessels. In the weeks to come, we’ll highlight how to inspect stainless steel, carbon steel, and hastelloy vessels.
Gather Relevant Information
The first thing you will want to do when conducting an inspection of a used vessel is to gather all of the relevant information associated with that particular vessel.
Specifically you will want to request that the seller provide:
- Access to the original nameplate. For the most part this nameplate can be found on the vessel, however sometimes they may have been removed, or are too faded to read in which case you will want to ask if the seller documented the nameplate information. This nameplate should display the following critical information: serial number, model number, date of construction, confirmed operating pressures, as well as A.S.M.E and National Board Code numbers.
- Original maintenance and service documents. It’s important to review these documents to ensure that all preventative maintenance and repairs were performed by a licensed professional so that the vessel’s National Board certification is not put in jeopardy
- Ask the seller to confirm, and provide documentation as proof, of the vessel’s material of construction.
