GOST 27036-86 PDF

Full title and description

GOST 27036-86 — "Компенсаторы и уплотнения сильфонные металлические. Общие технические условия" / "Metal bellows expansion joints and seals. General specifications". A national (interstate) standard originally approved by the USSR State Committee for Standards that defines technical requirements, test methods, marking, packaging, acceptance rules and operational guidance for metal bellows used as expansion joints and seals.

Abstract

GOST 27036-86 establishes general technical conditions for metal bellows expansion joints and metal bellows seals intended for hermetic connections and separation of fluid volumes where relative movement occurs. The standard sets out product parameters and dimensions, materials and fabrication requirements, safety and testing procedures (acceptance, qualification, periodic and type tests), marking, packaging, transportation and manufacturer guarantees, and gives instructions for use and reliability requirements. Certain installations (for example some underground tunnel-free installations and special military orders) are excluded from the scope.

Scope

This standard applies to metal bellows used in expansion joints and to metal bellows seals intended for forming hermetic connections between relatively moving elements of mechanisms, devices and pipelines, and for separating volumes of liquids and gases where relative movement is present. It specifies technical requirements for design parameters, materials, manufacturing, acceptance and test regimes, marking, packaging, transport and operation. Exclusions include certain tunnel-free underground installations and special bellows produced under direct orders of defense authorities.

Key topics and requirements

• Definitions and terminology for bellows, expansion joints and seals (cross-references to related GOST terminology standards).
• Main parameters and dimensional series (nominal diameters, pressure classes, allowable movements and travel ranges).
• Material and fabrication requirements for bellows, end fittings and welds, including selection of steels and corrosion‑resistant alloys.
• Design strength, stiffness and thermal-resistance criteria; allowable working pressure and temperature guidance.
• Safety requirements for manufacture, installation and operation (references to occupational and pressure-vessel safety rules).
• Testing regime: acceptance, qualification, periodic and type tests with required sample sizes and pass/fail criteria (strength, leak tightness, vibration and impact, life/cycle tests).
• Quality control, inspection and documentation requirements (factory tests, certificates, marking and traceability).
• Packaging, transportation and storage provisions to protect functionality and prevent damage during handling.
• Operational instructions and manufacturer guarantees, including recommended maintenance and inspection intervals and conditions for re-testing.

Typical use and users

Used by manufacturers of metal bellows and expansion joints, piping and pressure-system designers, procurement and quality departments, test laboratories, plant maintenance teams and engineering firms in industries such as power generation, oil & gas, petrochemical, chemical processing, shipbuilding, HVAC and other sectors where controlled compensation for thermal, mechanical or seismic movement in piping and equipment is required.

Related standards

Commonly associated and cross-referenced documents include GOST standards on terminology and related materials/testing (for example the GOST for bellows terms and definitions), national safety and welding standards, material standards for steels and alloys, and international equivalents or guidance such as ISO documents on metal bellows and regional EN standards for metal bellows expansion joints. Users should consult the normative references listed in the standard for precise cross‑references.
