A cylinder made in conformance with DOT Specifications 4B, 4BA, 4BW, or 4E protected externally by a suitable corrosion-resistant coating and used exclusively for non-corrosive gas that is commercially free from corroding components may be requalified by volumetric expansion testing every 12 years instead of every 5 …
How often do LPG tanks need to be tested?
every ten years
These inspections must be conducted every ten years. As such, owners must ensure that the LPG tank is inspected before a period of ten years has elapsed after the date indicated on the tanks. This date will be checked by authorised LPG examiners at the time of inspection for renewal of registration.
How do I know if my propane tank is expired?

Why is Hydrotesting necessary?
Hydrostatic (Hydro) Testing is a process where components such as piping systems, gas cylinders, boilers, and pressure vessels are tested for strength and leaks. Hydro tests are often required after shutdowns and repairs in order to validate that equipment will operate under desired conditions once returned to service.
How often do cylinders need to be hydrostatically tested?
every 5 years
High pressure cylinders are required to be hydrostatically tested every 5 years with the exception of composite and hoop wrapped cylinders manufactured prior to 2002 which are required to be tested every 3 years. All composite or wrapped cylinders have a 15 year service life.
How many times can you recertify a propane tank?
The “requalification” date, also known as the “retest” date , is an important marking for fillers and/or consumers. Propane cylinders must be requalified or replaced every 5 or10 years depending on the cylinder type, condition, and previous requalification method.
What is a 3AA cylinder?
(1) A DOT-3AA cylinder is a seamless steel cylinder with a water capacity (nominal) of not over 1,000 pounds and a service pressure of at least 150 psig.
What does 4BW mean?
A DOT 4BW cylinder has a spherical or cylindrical design, a water capacity of 1,000 pounds or less, and a service pressure range of 225 to 500 psig.

Is Hydrotest mandatory?
Hydrostatic testing of pressure piping is a mandatory activity before finalization of any new or modified piping system. It is the final check of mechanical integrity of the whole system and should be followed religiously as after this activity the piping system has to be commissioned.
What happens if we do not hydrotest our cylinders?
What happens if the cylinder fails? In the unlikely circumstance that the cylinder fails the hydro test, a test report will be given to the customer and the cylinder must be destroyed.
How are cylinders hydrostatically tested?
CYLINDER HYDROSTATIC TESTING
During a hydrostatic test, a pressure vessel is placed inside a closed system, usually a test jacket filled with water, and a specified internal water pressure is applied to the container inside this closed system.
Is it worth recertifying a propane tank?
Propane cylinders must be recertified every 10 years. This means that the relief valve must be replaced and the cylinder must be visually inspected.
