What does ASME mean on extraction systems? It could mean not blowing yourself up!

Formed in 1880, in response to the frequent occurrences of boiler explosions, the American Society of Mechanical Engineers (ASME) established the use of standard engineering practices for companies that employed engineers. Today, ASME is internationally renowned for its rigorous standards for boiler and pressure vessel codes known as ASME Section VIII. 

The National Board of Boiler and Pressure Vessel Inspectors was created in 1919 to promote greater safety to life and property through uniformity in the construction, installation, repair, maintenance, and inspection of pressure equipment.

The National Board Certification Program accredits manufacturers of pressure relief devices and assemblers of pressure relief valves which are designed, constructed, tested, and marked following specified Codes (ASME) recognized by the National Board.

National Board Inspection Code

Before the establishment of the National Board Inspection Code, a boiler manufactured in one state would not necessarily be accepted for operation in another state even if it had been constructed under the ASME code. States and several large cities had their own qualification requirements for inspectors, which, in most cases, meant little or no reciprocity. For a boiler to be installed in a state other than in which it was manufactured required inspections to be performed – during fabrication – by an inspector from the state where the boiler would be installed. This was costly and discouraged boiler sales across state borders.

The National Board of Boiler and Pressure Vessel Inspectors knew it had to find an answer to the problem. The solution came in two parts:

  • qualifying all inspectors to a common set of requirements and issuing a National Board commission to successful candidates; and
  • authorizing manufacturers to stamp a National Board number on boilers inspected by a National Board Commissioned Inspector.

Registration of a boiler with a National Board number could now be completed with the manufacturer submitting an original manufacturer’s data report to the National Board for permanent retention. This document, certified by both the manufacturer and the National Board Commissioned Inspector, gave the chief boiler inspectors of all participating states and cities the assurance they needed to allow a boiler to be installed for operation within their respective jurisdictions.

Basically, the ASME and NB set and oversee the standards for boiler and pressure vessels that maintain the quality and safety of the systems.

Now, what does this mean for your extraction system?

In essence, cannabis and hemp extraction systems are a series of pressure vessels plumbed together and should be held to the same standards that every other industry adheres to under ASME and the NB. However, this is not always the case, many extraction equipment companies use sub-par tanks, steel, and components made in foreign countries that have little to no manufacturing oversight or standards and “claim” that they meet ASME standards. However, simply “meeting” ASME standards does not mean a system is ASME rated. This could cause leaks, compromised or weakened welds, and so on…these defects could lead to explosions.  

IRON FIST EXTRACTORS is one of the few extraction system manufacturers and uses 100% American made steel and components, furthermore, all of the components that are required to meet ASME are STAMPED with an ASME logo and NB logo with a registration number. Before purchasing an extraction system be sure to ask if the systems are ASME and NB stamped.
