Pressure vessels are containers that hold liquids or gases at a pressure that differs substantially from the outside pressure. Pressure vessels can be found in homes and industrial facilities all over the world. Some applications of pressure vessels include in steam boilers, engine cylinders and storing chemicals or petroleum products. These examples only begin to scratch the surface, as pressure vessels have nearly endless applications.

While pressure vessels are extremely useful and likely will continue to be used indefinitely into the future, they can be problematic. The difference between the pressure inside a pressure vessel and the pressure outside makes for a potentially hazardous situation. Pressure vessels have long been known to be dangerous and have caused fatal accidents in the past. Because of this, the way pressure vessels are made and used is specified by engineering authorities, and these authorities are supported by governmental legislation.

These standards also specify the need for testing and include guidelines for pressure vessel inspection procedures. The inspection of pressure vessels is both required and smart practice for anyone who wants to avoid an accident that could result in unplanned downtime, damaged equipment and potentially fatal injury to workers.

In this article, we’ll learn more about different types of pressure vessels, what pressure vessel inspections consist of and when they’re required as well as different methods of testing.

Pressure vessels are designed differently based on their end application, though they all tend to look similar and include the same basic parts. Pressure vessels are typically cylindrical with rounded edges or are spherical. That’s because these shapes avoid stress raisers.

Storage tanks are the most common type of pressure vessel. They come in various shapes and sizes, but they are all designed to store liquids and gases under pressure. They might hold fuel oil, liquefied hydrogen or compressed natural gas or other materials that are valuable in industrial applications. These tanks are often made from carbon steel, though they may be coated in a different material on the inside. A typical residential example of a storage tank is a well pressure tank, which pressurizes water before it enters into a home’s plumbing system. After storage tanks, heat exchangers are the second most common type of pressure vessel. Heat exchangers transfer heat between mediums, often liquids. This way, heat exchangers are useful for both cooling and heating processes. Heat exchangers can be found in furnaces in homes all over, but they are also essential to processing and manufacturing plants. A common type of heat exchanger used in chemical processes is the shell and tube. With this type, within a pressurized shell, one liquid runs through tubes while the other liquid flows over the tubes, causing heat to transfer from one liquid to the other.

Process vessels, as the name suggests, are used to facilitate a process in a controlled environment. This process is typically one step in a more extensive process. This sub-process could involve combining materials, separating materials, agitating a mixture, breaking down products or removing an element from a product. Process vessels are designed and constructed with the specific process they’re intended for in mind. Sub-types of process vessels include:

Drums

Reactors

Columns

Gravity separators

A pre-production inspection tells the buyer which kind of raw materials (or components) will be used. Factories are often suspected of lowering their costs by purchasing substandard materials, and this can be disastrous for the buyer (e.g. the wrong kind of chip in an electronic device).

A during production inspection (often called “DUPRO” in the industry) allows the buyer to have an idea of average product quality, early in the production cycle. It is the most useful and the most under-rated tool at the disposal of importers, who often only rely on final inspections.

The final random inspection (also called “pre-shipment inspection”) is by far the most common type of QC check. It takes place once 100% of shipment quantity is finished and at least 80% is packed, so it can be a real random inspection (this is not exactly the case if quality is checked earlier) and suppliers cannot play games.

The container loading inspection, like the pre-production inspection, it is seldom used. But it can be a worthwhile option in some specific cases.

• Visual inspection of external hoist parts, trolley frames, catwalks, handrails for loose bolts, broken parts, misalignments, broken welds, or any other unusual conditions

(gear case will not be internally inspected)

• Inspection of all safety devices (i.e. check limit switches for proper operation)

• Inspection of electrical controls by opening control boxes and checking all contactors,relays, timers, etc. (checked for proper operation and loose or broken connections)

• Inspection of general condition of end trucks, rail sweeps, drop lugs and shock absorbing bumpers

• Inspection of motor brakes for proper operation or possible need of adjustment or replacement of brake discs, studs, coils, shoes, etc. (adjustment of electric brakes will be included at no additional charge)

The validation scope, boundaries and responsibilities for each process or groups of similar processes or similar equipment's must be documented and approved in a validation plan. These documents, terms and references for the protocol authors are for use in setting the scope of their protocols. It must be based on a Validation Risk Assessment (VRA) to ensure that the scope of validation being authorised is appropriate for the complexity and importance of the equipment or process under validation. Within the references given in the VP the protocol authors must ensure that all aspects of the process or equipment under qualification; that may affect the efficacy, quality and or records of the product are properly qualified. Qualification includes the following steps:

Demonstrates that the proposed design (or the existing design for an off-the-shelf item) will satisfy all the requirements that are defined and detailed in the User Requirements Specification (URS). Satisfactory execution of the DQ is a mandatory requirement before construction (or procurement) of the new design can be authorised.

Demonstrates that the process or equipment meets all specifications, is installed correctly, and all required components and documentation needed for continued operation are installed and in place.

Demonstrates that all facets of the process or equipment are operating correctly.

Demonstrates that the process or equipment performs as intended in a consistent manner over time.

This term refers to the manufacturing of auxiliary components to ensure that they are manufactured to the correct design criteria. This could include packaging components such as folding cartons, shipping cases, labels or even phase change material. All of these components must have some type of random inspection to ensure that the third party manufacturer's process is consistently producing components that are used in the world of GMP at drug or biologic manufacturer.
