of its standards are recognized internationally.


Identification ASME BPVC Section VIII, Division 1   
     Rules for Construction of Pressure Vessels
    Division 1

Scope This Division of Section VIII provides requirements applicable to the design, fabrication, inspection, testing, and certification of pressure vessels operating at either internal or external pressures exceeding 15 psig.

 

Status Published and available through ASME.
For hydrogen applications see reference to “Project Team on Hydrogen Tanks” in Sections VIII, Division 3, X and XII below.

Identification ASME BPVC Section VIII, Division 2
   
Rules for Construction of Pressure Vessels
   
Division 2, Alternate Rules

 

Scope Same scope as Division 1 except requirements on materials, design and nondestructive examination are more rigorous; however, higher design stress intensify values are permitted.
Status Published and available through ASME.

Identification ASME BPVC Section VIII, Division 3
   
Rules for Construction of Pressure Vessels
    Division 3, Alternate Rules High Pressure Vessels

    Article KD-10

    Special Requirements for Vessels in High Pressure

    Gaseous Hydrogen Transport and Storage Service

 

Scope Division 3: Same scope as Divisions 1 & 2 except for pressures above 10,000 psig.

 

Article KD-10:

For all vessels in gaseous hydrogen transport and storage service. Each pressure component shall be evaluated for the specified fatigue cycle and shall meet the fracture toughness requirements in this article. These requirements are in addition to other requirements in Division 3.

 

Status Published and available through ASME.

A Project Team on Hydrogen Tanks is developing new rules for metallic and composite construction for hydrogen tanks operated at pressures up to 15,000 psig. Its strategy includes development of Code Cases for hydrogen specific applications written in conjunction with current rules published in the ASME BPV code, rather than development of a completely new code for hydrogen pressure vessels. Code cases are being written for expedited approval and publication of the technology and thus, allow for early implementation. The primary BPV code rules being addressed are Section VIII, Division 3 and Section X.

 

 The following actions have been completed:

·        Article KD-10 – Special requirements for fracture resistance of all-steel vessels in Section VIII, Division 3

·        Code Case 2579 – Hoop-wrapped Composite Reinforced Pressure Vessels with Welded Liners for Gaseous Hydrogen Service; Section VIII, Division 3

·        Code Case 2569 – SA-372 Steel Construction for Use in High-Pressure Hydrogen Application; Section VIII, Division 3

·        Code Case 2563 – Aluminum Alloy 6061 Construction for Use in High-Pressure Hydrogen Applications; Section VIII, Division 3

 

Actions underway include:

·        Code Case for Fully Wrapped Fiber Reinforced Composite Pressure Vessels with Non-Load Sharing Liners for Gaseous Hydrogen Service for Section X application as a new class 3 up to 15,000 psi

·        Guidelines for in-service inspection of composite hydrogen vessels.

ASME Code Case 2390

     Composite Reinforced Pressure Vessels

Scope This case allows construction of CRPVs consisting of metallic cylindrical layer wrapped circumferentially with a layer of glass fiber reinforced plastic laminate leaving the metallic heads unwrapped.
Status Published and available through ASME.

Identification

ASME BPVC-Section X    Fiber-Reinforced Plastic Pressure Vessels

 

Scope This Section provides requirements for construction of an FRP pressure vessel in conformance with a manufacturer’s design report.
Status Published and available through ASME.
For hydrogen applications see reference to “Project Team on Hydrogen Tanks” in Section VIII, Division 3 above.
The 2010 edition (Appendix 8) allows 15,000 psi composite tanks, using non-load-sharing liners, for stationary hydrogen storage.

Identification ASME BPVC-Section XII
    Transportation Tanks

 

Scope This Section includes transport tanks currently covered under DOT specifications and 49 CFR requirements, specifically, Portable Tanks, Cargo Tanks and Rail Tank Cars.
Status Published in 2004. It is available through ASME. A “Project Team on Hydrogen Tanks” has been formed and is working to expand this standard to include requirements for hydrogen. The work of this team will also affect Section VIII Divisions 1 and 3, Code Case 2390 and possibly Section X.

Key activities include: 
1.
  Fracture resistance requirements, 
2.
  Addition of new materials, 
3.
  Design margins for composite vessels, 
4.
  New code case for composite vessels, 
5.
  Revision of Code Case 2390, 
6.
  Metal hydride vessel design, and 
7.
  Improved methods for in-service inspection.
