Name in English:
GOST 25365-82
Name in Russian:
ГОСТ 25365-82
Steam and hot water boilers. General technical requirements
Full title and description
ГОСТ 25365-82 — Котлы паровые и водогрейные. Общие технические требования. Требования к конструкции. (Steam and hot-water boilers — General technical requirements — Construction requirements). This interstate standard establishes general technical and construction requirements for the design and manufacture of steam and hot-water boilers.
Abstract
The standard defines mandatory construction, welding and connection practices, dimensional and strength considerations for boiler drums, collectors and associated components, and prescribes minimum requirements for openings, manholes, tube joints and related fabrication operations to ensure safe and reliable operation of steam and hot-water boilers. It was issued as an interstate (USSR) standard and remains the reference normative document for these aspects of boiler design.

Scope
Applies to stationary steam and hot-water boilers and sets out general technical requirements and construction rules that manufacturers, designers and certifying authorities must apply when fabricating boiler drums, collectors, shells and associated assemblies. The scope includes requirements for welding, tube-to-drum connections, hole and manhole design, permissible constructional solutions and associated strength justifications.
Key topics and requirements
- General construction principles for steam and hot-water boilers (drums, collectors, shells).
- Requirements for welded joints in boiler bodies, drums and collectors (references to welding standard ГОСТ 24663-81).
- Rules for tube-to-drum and tube-to-collector connections: welding or expanded (roll‑expanded) joints with limits on tube diameters and wall temperatures.
- Dimensional and strength justification for hole placement and spacing in drums, collectors and heads; edge finishing requirements for openings under specified pressure conditions.
- Manhole and handhole sizing and shape requirements for accessibility and maintenance (minimum dimensions for various opening shapes).
- References to related intergovernmental (СЭВ/ST SEV) documents where applicable for harmonized requirements.
Typical use and users
Used by boiler designers, manufacturers and fabricators of steam and hot-water boilers, quality and inspection engineers, certification bodies, technical regulators and organizations responsible for commissioning and maintenance of industrial and district heating boiler plants. It serves as a normative baseline for construction safety, fabrication practices and inspection criteria.
Related standards
Normative cross-references and related documents include ГОСТ 24663-81 (welding requirements referenced for welded joints), СТ СЭВ 722-77 (placement and spacing of holes — when referenced), and the intergovernmental standard ST СЭВ 2684-80 cited as a synonym/related document in catalog records. Additional national and industry standards on pressure equipment, materials and testing complement this standard.

FAQ
Q: What is this standard?
A: ГОСТ 25365-82 is an interstate standard that specifies general technical and construction requirements for steam and hot‑water boilers (boiler drums, collectors, shells and related assemblies).
Q: What does it cover?
A: It covers construction rules, welding requirements, tube-to-drum connection methods (welded and roll-expanded within specified limits), requirements for openings and manholes, dimensional/strength justification for hole placement, and related fabrication practices necessary for safe boiler operation.
Q: Who typically uses it?
A: Boiler designers, manufacturers, fabricators, inspection and certification bodies, maintenance teams and regulatory authorities involved with industrial and heating boilers.
Q: Is it current or superseded?
A: Catalog and normative records list ГОСТ 25365-82 as действующий (effective). Historical notes indicate original approval in 1982 and effective date 01 July 1983; an amendment (Изм. N 1) exists. Users should verify applicability in their jurisdiction and check for any newer national regulations that may complement or replace parts of the standard.
Q: Is it part of a series?
A: It is a general technical/construction standard for boilers and is published alongside other GOST/ST standards for pressure equipment, welding and testing; it also cross-references specific welding and СЭВ/ST documents. It functions as one element in the broader body of boiler-related standards.
Q: What are the key keywords?
A: Boilers, steam, hot-water, construction requirements, welding, drum, collector, tube joints, manholes, ГОСТ 25365-82.
