Full title and description

GOST R 55601-2013 — Heat exchanger apparatuses and air cooling apparatuses. Tube expanding in tube-sheets. General technical requirements. The standard establishes technical requirements, methods of fastening tubes in tube‑sheets (including rolling/expanding and combined joints), acceptance and verification tests, and guidance for repair operations.

Abstract

This national standard specifies general technical requirements for the fastening of tubes in tube‑sheets used in shell‑and‑tube heat exchangers and air‑cooling apparatuses. It covers types of tube‑to‑tube‑sheet joints, classes of accuracy, recommended tooling and torques for expanding operations, inspection and acceptance criteria, and repair provisions for tube holes. The document is intended to ensure mechanical integrity and leak tightness of tube joints across typical industrial applications.

Scope

The standard applies to shell‑and‑tube heat exchanger apparatuses and air‑cooling apparatuses and defines requirements for securing tubes in tube‑sheets (tube‑to‑tube‑sheet joints). It addresses rolling/expanding joints, combined joints (welding plus expanding), classes of joint accuracy, allowable dimensions after processing, recommended torques and procedures for expanding (developed by material and joint type), inspection criteria, and special instructions for repair and for apparatuses made to individual designs. It is intended for application at manufacturing, assembly and repair stages.

Key topics and requirements

• Classification of tube‑to‑tube‑sheet joint types (rolling/expanding types R1–R5 and combined/welded variants) and recommended application rules.
• Five classes of joint accuracy with associated dimensional and surface‑roughness limits.
• Specified guidance for expanding (rolling) operations: recommended torques, sequence of operations, measurement and acceptance criteria (internal diameters after expanding, cone tolerance).
• Inspection and test requirements including sampling, measurement tolerances, and acceptance rules for newly manufactured and repaired joints.
• Requirements for tooling, cleaning/preparation before expanding, and special provisions for different material groups and apparatus executions.
• Repair guidance: dimensions for repair (5th class) holes, machining allowances and limits for re‑rolling/expanding repaired joints.

Typical use and users

Used by designers, technologists, manufacturers and repair shops of shell‑and‑tube heat exchangers and air coolers, quality and inspection personnel, and purchasing/specification engineers who prepare technical documentation for manufacturing or procurement of heat‑exchange equipment. It is also referenced by project organizations when specifying tube‑joint arrangements for individual apparatus designs.

Related standards

The standard contains normative references and cross‑references to other GOSTs and technical documents relevant to tubes, welded joints, surface roughness and material properties (examples cited in the text include GOST 494, GOST 550, GOST 2789, GOST 3242 and others related to tube materials and joining). It is commonly used together with standards and specifications for specific tube materials, welding procedures and pressure‑equipment design rules.
