GOST 31842-2012 PDF

Full title and description

GOST 31842-2012 — Petroleum and natural gas industries. Shell-and-tube heat exchangers. Technical requirements. The standard establishes technical requirements for the design, materials, fabrication, inspection, testing and preparation for shipment of steel shell‑and‑tube heat exchangers intended for use in the petroleum, petrochemical, natural gas and related process industries.

Abstract

This standard specifies mandatory and recommended provisions for shell‑and‑tube heat exchangers (including heaters, condensers, coolers and reboilers) used in petroleum and natural gas industry applications. It covers mechanical design principles, material selection, construction methods (including tube‑sheet and floating‑head arrangements), nondestructive testing and acceptance tests, marking, documentation and packing for shipment. Certain equipment (for example vacuum-operated steam surface condensers and feed‑water heaters) is excluded where noted in the text.

Scope

GOST 31842-2012 applies to steel shell‑and‑tube heat exchangers intended for the petroleum, petrochemical, gas and allied industries. It sets out requirements for overall design (mechanical strength, thermal considerations, allowance for corrosion/cladding), selection of materials, details of fabrication (welding, tube installation, tube‑sheet construction), quality control procedures, nondestructive testing, routine and acceptance tests, documentation and preparation for transport. The standard is not intended for certain specialized condensers and feed‑water heaters operating under vacuum as specifically excluded.

Key topics and requirements

• Design requirements: mechanical strength, allowable stresses, temperature and pressure ratings, thermal expansion arrangements (floating head, U‑tubes, expansion joints).
• Material selection: compatible materials for shell, tubes, tube‑sheets and baffles; corrosion allowance and cladding guidance.
• Fabrication and construction: welding procedures, tube rolling/expanding, tube‑bundle assembly and clearances, supports and attachments.
• Inspection and testing: mandatory nondestructive examinations (radiography, ultrasonic, dye penetrant, etc.), pressure tests (hydrostatic), leak tests and performance checks.
• Documentation and records: drawings (outline and for manufacture), material certificates, test reports and manufacturer’s data book requirements.
• Packing and shipment: preservation, marking, lifting and transport requirements to ensure safe delivery.
• Types covered and exclusions: heaters, condensers, coolers and reboilers are included; vacuum steam surface condensers and feed‑water heaters are excluded where stated.

Typical use and users

Used by equipment manufacturers, mechanical designers, quality and inspection engineers, plant owners/operators and procurement specialists in the oil, gas, petrochemical and chemical industries. Typical applications include process heat exchangers in refineries, gas processing plants, petrochemical units and associated utilities. The standard is used to develop technical specifications, perform design reviews, prepare manufacturing documentation and carry out acceptance testing.

Related standards

Commonly related and cross‑referenced documents include ISO 16812 (international shell‑and‑tube heat exchanger standard), the later ISO/EN revisions of that standard, national GOST documents on welded pressure equipment and strength calculation (e.g., GOST/GOST R series on vessels and pressure apparatus), and technical specifications (TU) for specific exchanger types. Examples of related documents used in practice: ISO 16812 (2007 and later revisions), GOST R 53677 (earlier GOST R document), GOST 34233.7 (strength calculation rules for heat exchangers) and GOST R 55601 (tube expanding and tube‑sheet requirements).

FAQ

Q: What is this standard?

A: GOST 31842-2012 is a Russian (GOST) technical standard that defines technical requirements for shell‑and‑tube heat exchangers used in petroleum, petrochemical and natural gas industries.

Q: What does it cover?

A: It covers mechanical design, material selection, fabrication practices, nondestructive inspection, pressure and leak testing, documentation and shipment preparation for shell‑and‑tube exchangers such as heaters, condensers, coolers and reboilers. Specific exclusions (e.g., certain vacuum condensers and feed‑water heaters) are noted in the standard text.

Q: Who typically uses it?

A: Manufacturers, mechanical and process designers, inspectors, testing laboratories, plant engineers and procurement teams in oil, gas, refinery and petrochemical sectors use the standard to ensure safe, reliable and interoperable exchanger equipment.

Q: Is it current or superseded?

A: The designation is GOST 31842-2012 (adopted 2012); it was published/entered into force on January 1, 2014 and is treated as the current GOST document for shell‑and‑tube exchanger technical requirements unless a later national revision or replacement has been issued by the standards body.

Q: Is it part of a series?

A: It is part of the family of standards and normative documents governing equipment for the petroleum and gas industries (including other GOST/GOST R standards on pressure equipment, strength calculation and testing). It incorporates or aligns with international practice through its relationship to ISO 16812 (the international shell‑and‑tube exchanger standard).
