Gas Equipment and Handling

Preface
This is the eighteenth edition of CSA B51, Boiler, pressure vessel, and pressure piping code. It supersedes the previous editions published in 2009, 2003, 1997, 1995, 1991, 1986, 1981, 1975, 1972, 1969, 1965, 1960, 1957, 1955, 1951, 1945, and 1939.

ASME has been defining piping safety since 1922.
ASME B31.3 contains requirements for piping typically found in petroleum refineries; chemical, pharmaceutical, textile, paper, semiconductor, and cryogenic plants; and related processing plants and terminals. It covers materials and components, design, fabrication, assembly, erection, examination, inspection, and testing of piping.

Preface
This publication represents a standard for safe operation, substantial and durable construction and performance testing of thermally activated pressure relief devices for compressed hydrogen vehicle fuel containers, for the on-board storage of compressed hydrogen for vehicle operation within limitations given below and in the scope of this standard.

This standard is based on proven engineering principles, research and the combined expertise of gas utilities, manufacturers, users, and others having specialized experience.

Preface
This is the first edition of ANSI HGV 3.1, Fuel system components for compressed hydrogen gas powered vehicles. This precedes CSA HGV 3.1-2013.

Scope
1.1
This Standard establishes requirements for newly produced compressed hydrogen gas fuel system components, intended for use on hydrogen gas powered vehicles as listed below:

a) check valves;

b) manual valves;

c) manual container valves;

Preface
This is the first edition of CSA HPIT 1, Compressed hydrogen powered industrial truck on-board fuel storage and handling components.

Scope
1.1

The IFC contains regulations to safeguard life and property from fires and explosion hazards. Topics include general precautions, emergency planning and preparedness, fire department access and water supplies, automatic sprinkler systems, fire alarm systems, special hazards, and the storage and use of hazardous materials. For the most current adoptions details go to International Code Adoptions

Key changes to the IFC include:

Provides a number of methods, describing in each case the apparatus required, precautions required, procedure and interpretation of the results of proving gas tightness of vacuum or pressurized plant. Contains over 100pp.

Provides information on the physical and chemical properties of hydrogen and proper handling and use. It is intended to provide background information for personnel involved in the manufacture, distribution, and use of hydrogen. Additional technical information can be obtained from hydrogen gas manufacturers.

This publication presents design guidelines for hydrogen vent systems used in gaseous and liquid hydrogen systems at user sites and provides recommendations for safe operation of these vents. It begins at the discharge port of safety devices and other components that control the release of hydrogen and ends at the point where hydrogen concentration in the atmosphere is below the lower flammable limits. It also provides information on the production, transportation, handling, and storage of compressed hydrogen, cryogenic liquid hydrogen, and related products.
