Pressure vessels are closed containers used to hold liquids, vapors, and gases at a pressure significantly higher or lower than normal. They are used in a number of industries, some of the most common being petrochemical, oil and gas, chemical, and food processing. The term “pressure vessel” can also be used to describe a number of pieces of equipment, including reactors, flash drums, separators, and heat exchangers. Openex manufactures both custom pressure vessels and large pressure vessels used in a wide variety of applications across the aforementioned industries.

When manufacturing a large pressure vessel, the first thing to consider is material. Which material can meet the strength requirements of a certain application? What about corrosion resistance? Cost-wise, it is also important to consider things like ease of fabrication, maintenance, and availability.

Next comes design and incorporating the customer’s specifications. This includes design pressure, maximum allowable working pressure, design temperature, maximum allowable stress, joint efficiency, and corrosion allowance. A large pressure vessel is fabricated through forging, rolling, and welding metal sheets. Then, auxiliary equipment and accessories are added to ensure the vessel can meet its application.

Lastly, the pressure vessel must be tested to make sure it will be reliable for the customer. This includes visual testing, ultrasonic testing, radiographic testing, magnetic particle testing, liquid penetrant testing, and pressure testing, as well as what Custom does: hydro-testing.
