Frequently asked questions

We have shared some of our most frequently asked questions here. If you can’t find the answer to your question, you can always ask us.

The ASME Codes for Pressure Vessel Design are utilized for pressurized equipment, such as vessels, piping, and fittings, in various regions around the world, including North America. These codes encompass the design, construction, maintenance, and modification of pressurized equipment. The commonly used ASME codes include:

 

  • VIII-1 for vessels, towers, and exchangers
  • I and IV for hot water heaters and boilers
  • B31.1, B31.3, and B31.5 for piping systems
  • B31.3 is often applied to various fittings

These codes rely on rule-based design and offer formulaic approaches that are effective when the design is within the limits of the code's scope.

The qualified welding procedure is owned by the company and not the welder who conducted the qualification tests. Therefore, departure of the welder will not affect the status of the qualified welding procedure and no requalifications are required.
A pressure vessel, fitting or piping that contains liquids not more hazardous than water and that operate at a temperature of 150°F (65°C) or less and at a maximum allowable working pressure of 250 psi (1,717 kPa) or less is exempt from TSSA boiler and pressure vessel regulations.
Professional inspections of boilers should occur on an annual basis, although there are various types of inspections that an inspector can conduct. To ensure safety and compliance, regulatory bodies and insurance companies typically advise that power boilers undergo both internal and external inspections annually, while they are not pressurized. Additionally, an external inspection of the boiler while it is under pressure is recommended halfway between the annual inspections.
If the computations do not require any changes, then the likelihood is that re-registration won't be necessary. For instance, if you're adding a nozzle that's similar to an existing one on the vessel and not positioned too near another nozzle, you probably don't need to register it again. However, you should get in touch with an authorized inspector in your area. It's crucial to note that only companies with a valid QC certificate, such as an ASME "R" stamp, should undertake the work.
If the calculations and drawings are available and the code of construction meets the acceptable standards, it may be worth considering. However, if non-ASME codes and materials are utilized, it is typically not worth the effort.
