Warranties and Standard Features on LPG / NGL Storage Vessels

Warranties on LPG / NGL storage vessels are typically for one year although at least one U.S. manufacturer offers a 10-year warranty.  The start of the warranty period will vary by manufacturer.  Some warranty periods start after completion of fabrication, some begin from the date of shipment while others begin from the date of installation.

Warranties most often state that the container will be free from defects in material and workmanship under normal and proper use in service.  Warranty coverage usually applies to…

…New storage vessels and does not apply to used equipment or any valves and related fittings, regulators, gauges, hoses and hose-end connections, anode bags, and similar equipment, part or attachment which is part of, attached to or sold with the product.

Manufacturer’s will not warranty components, parts or accessories not manufactured by it, but in the event of a defect of a component part or accessory, they will provide reasonable assistance in obtaining (from the respective manufacturer) whatever adjustment is authorized by that manufacturer’s own warranty.

Warranties are not typically transferable.  The warranty extends to the original purchaser to whom storage vessel was first delivered and who first places the vessel in service.

The purchaser’s remedy generally consists of the manufacturer repairing or replacing without charge, any defective item covered by the warranty.
