T/CAS 851-2024 Technical specifications for hydrogen transportation industrial piping
Basic Information
Scope
This document specifies the design, construction, acceptance, operation, and maintenance of industrial pipelines for hydrogen transportation.
This document applies to the new construction and modification of industrial pipelines for hydrogen gas during the production, storage, dispensing, refueling, and use processes, where the volume fraction of hydrogen is 50% or higher, and the design temperature range is -40°C to 65°C, with a design pressure range of 0 MPa to 100 MPa.
The industrial pipelines for hydrogen transportation referred to in this document are those used in hydrogen production plants (stations), hydrogen dispensing stations, hydrogen refueling stations, hydrogen storage stations, natural gas-hydrogen mixing stations (the gaseous hydrogen pipeline part), hydrogenation stations, and factory-owned hydrogen production devices, etc.
The industrial pipelines for hydrogen transportation referred to in this document do not include coke oven gas pipelines, power pipelines, long-distance hydrogen pipelines, mobile equipment pipelines, military and aerospace pipelines, nuclear power station pipelines, etc. The industrial pipelines for hydrogen transportation referred to in this document do not include the internal pipelines of heaters, boilers, pumps, compressors, fluid control equipment, etc., nor do they include directly buried hydrogen industrial pipelines.
