Some Considerations When Designing and Manufacturing Pressure Vessels for Oil and Gas Industry

Pressure vessels are essential to execute several critical operations in the oil and gas industry. Several types of pressure vessels are used to store and transport gases and liquids at high pressures.

Considering the critical nature of the applications, pressure vessels must be designed and manufactured following several standards. Faulty design and manufacturing may lead to several catastrophic accidents, claiming valuable lives and damaging property.

Tips to Avoid Imperfect Design and Defective Manufacturing

Consider the following when designing and engineering pressure vessels meant for oil and gas industry applications.

  • Construction in Conformance to International Standards: Several disastrous accidents in the past have paved a way for Governments to impose several regulatory standards, including ASME (International Boiler and Pressure Vessel code) Code and P.E.D (European Pressure Equipment Directive). Both these codes provide detailed guidelines to pressure vessel manufacturers on designing, fabricating, inspecting, and testing of pressure vessels. Also, these standards provide general guidelines and rules pertaining to raw material selection, material specification, welding and brazing.
  • As an application user, you must ensure that you are purchasing pressure vessels from a certified manufacturer. Always ensure that the vessel is imprinted with ASME standard symbol or similar other international standards. If it is imprinted with the international standard symbol, you can be assured of its quality and durability. Only pressure vessels meeting all safety guidelines are liable to get certified.

  • Use of Quality Tested Raw Materials: The quality of raw materials determines the durability and efficiency of the end product. All the raw materials must be selected by following the guidelines of governing bodies like ASME or P.E.D. Being a corrosion resistant and strong material, stainless steel and its alloys are commonly preferred for pressure vessel manufacturing.
    • Operating conditions, temperature, pressure and humidity range in the application areas.
    • Properties of raw materials and their strengths and weaknesses.
    • Corrosive nature of the application area.
    • Type of construction – forged, casted or welded.
    • The type of liquid/gas that is stored, processed, and transported.

    A clear understanding on all these points will help the manufacturer design and engineer pressure vessel of quality, and according to customers’ specifications.

  • Rigorous Testing: Rigorous quality inspection helps detect any design or manufacturing flaw. Tests can also ascertain whether the unit meets all the design specifications provided by the customers. Testing, which is the final stage in pressure vessel manufacturing, certifies whether the unit is ready or not for field use.
  • Inspection methods include:

    • Visual Inspection – For identifying cracks of defects on the surface.
    • Ultrasonic Inspection – For detecting wall thinning.
    • Pneumatic and Hydrostatic Test – For detecting leaks.

    Faulty design and flawed manufacturing are the major reasons for most pressure vessel failures. Pressure vessel failure may lead to explosions, claiming valuable lives in the vicinity, along with damaging property. Hence, utmost attention must be paid by manufacturers throughout the vessel design and production phases.
