GOST 34294-2017 PDF

Full title and description

GOST 34294-2017 — Cryogenic pipeline valves. General specifications. (Russian: ГОСТ 34294-2017, Арматура трубопроводная криогенная. Общие технические условия). The standard sets general technical requirements for design, materials, manufacture, testing, marking and packaging of cryogenic and low-temperature pipeline valves.

Abstract

This interstate (GOST) standard specifies requirements for pipeline valves intended for cryogenic and low-temperature service: design and material selection, manufacturing and acceptance rules, methods of control and testing, reliability and safety indicators, and resistance to external influences. It harmonizes with international practice (based on ISO 28921‑1:2013) and is intended to cover isolating and other valve types used at temperatures down to liquefied-gas levels.

Scope

The standard applies to all types and designs of cryogenic and low-temperature pipeline valves with nominal pressure up to PN 250 and for working-medium temperatures from −50 °C down to −270 °C. It establishes requirements for valve construction, materials, manufacturing, delivery completeness, marking and packaging, acceptance rules, control and testing methods, reliability and safety metrics, and resistance to external influences.

Key topics and requirements

• Design requirements for valves intended for low-temperature and cryogenic service (materials, clearances, thermal considerations).
• Material selection and list of recommended construction materials suitable for temperatures down to −270 °C.
• Manufacturing and inspection rules, including nondestructive examination and dimensional checks.
• Acceptance criteria, factory testing and production test methods (pressure tests, tightness, operational tests).
• Marking, packaging and delivery completeness requirements for safe transport and identification.
• Reliability, safety indicators and resistance to external influences (mechanical, thermal, corrosive environments).
• Alignment with international standard ISO 28921‑1:2013 for low-temperature isolating valves (informative references and harmonization).

Typical use and users

Used by valve manufacturers, design and engineering organizations, procurement and quality departments, test laboratories, and end users in cryogenic industries — for example LNG plants, industrial gas production and distribution, cryogenic storage, scientific installations and other systems handling liquefied gases and low-temperature fluids. The standard guides designers and manufacturers in producing valves suitable for safe and reliable low-temperature operation.
