GOST 34347-2017 PDF

Full title and description

GOST 34347-2017 — "Сосуды и аппараты стальные сварные. Общие технические условия" (Steel welded vessels and apparatus — General technical conditions). The standard sets general technical requirements for the design, materials, manufacture, testing, acceptance, delivery, reconstruction, repair and installation of steel welded pressure vessels and apparatus used in process industries.

Abstract

This standard establishes mandatory and recommended requirements for steel welded vessels and apparatus operating under internal or external pressure, vacuum (residual pressure not less than 665 Pa / 5 mmHg) or without pressure (for filling). It covers constructional requirements, materials, welding and heat-treatment rules, non‑destructive testing, strength calculation references (links to GOST 34233 series and related calculation standards), acceptance criteria, documentation and marking, plus provisions for reconstruction, repair and installation. The standard is intended to harmonize national rules with the Technical Regulation of the Customs Union on pressure equipment and with relevant international practice.

Scope

The standard applies to steel welded vessels and apparatus designed and manufactured for use in chemical, petrochemical, oil refining, gas processing, oil & gas and related industries. It covers vessels operating under overpressure, vacuum (with residual pressure ≥ 665 Pa) or without pressure (for filling), and intended for strength calculation according to the GOST 34233.1–34233.12 series and GOST 34283. The scope includes new manufacture, acceptance testing, delivery, commissioning, reconstruction and repair of such equipment.

Key topics and requirements

• Design and construction requirements for vessel shells, heads (dished ends), transitions, nozzles, manholes and attachments.
• Material requirements for plates, pipes and forgings, including selection rules for carbon and low‑alloy steels and allowable alternatives.
• Welding requirements, weld classification, filler materials and qualifications for welding procedures and personnel.
• Mandatory and local heat‑treatment rules (including clause references for heat treatment of welded assemblies and local heating restrictions).
• Non‑destructive testing methods and acceptance criteria (radiography, ultrasonic, dye‑penetrant, magnetic particle where applicable).
• Strength calculation and design verification in accordance with referenced GOST calculation standards (GOST 34233 series and GOST 34283).
• Requirements for testing (hydrostatic/ pneumatic tests), inspection, documentation, marking and traceability.
• Provisions for reconstruction, repair, installation and requirements for protective measures against deformation and corrosion during heat treatment and handling.

Typical use and users

Primary users are design engineers, pressure‑vessel manufacturers, welding and quality control specialists, inspection bodies, plant operators in chemical, petrochemical, oil & gas and process industries, and regulatory authorities responsible for conformity assessment of pressure equipment in Russia and CIS countries. The standard is used for technical specifications, procurement, design verification and conformity checks.

Related standards

Key related documents include the GOST 34233.1–34233.12 series (strength calculation methods for vessels and apparatus), GOST 34283, national and interstate safety regulations for pressure equipment (TR CU 032/2013), and referenced international standards such as ISO documents on pressure equipment and boilers. The standard also cross‑references many material, testing and welding GOSTs used for manufacturing and inspection.
