SNiP 3.05.05-84 PDF

Full title and description

SNiP 3.05.05-84 — "Technological equipment and process pipelines" (Russian: СНиП 3.05.05-84 «Технологическое оборудование и технологические трубопроводы»). The document contains rules and technical requirements for production, installation, testing and acceptance of technological equipment and process (technological) pipelines used in industrial plants.

Abstract

SNiP 3.05.05-84 establishes requirements for manufacture, assembly, mounting, testing and acceptance of process equipment and pipelines intended for obtaining, processing and transporting raw, intermediate and final products, including piping for heat carriers, lubrication and other service media. The standard includes provisions on design documentation, fabrication of assembly units, welding and non‑removable joints, mounting loads and supports, hydraulic and pneumatic tests, corrosion protection and acceptance procedures. Key scope limits (pressure ranges) and test practices are specified in the text.

General information

• Status: Historically issued SNiP; later incorporated into/updated by modern SP rules (see note on replacement).
• Publication date: Approved by Gosstroy USSR on 7 May 1984; introduced/entered into force 1 January 1985.
• Publisher: Approved by the State Committee for Construction of the USSR (Gosstroy).
• ICS / categories: Construction / building services and industrial pipelines; normative documents for technological (process) pipelines and equipment (SNiP series 3.05.*).
• Edition / version: Original SNiP edition (1984/1985). Some later consolidated rules (SP 75.13330.2011) update or replace the SNiP provisions for current practice.
• Number of pages: Vendor and archive copies vary by publication/format (commonly shown as about 22 pages in some catalogs, ~34 pages or other counts in other editions).

Scope

The standard applies to production and acceptance of works on installation of technological equipment and process pipelines intended for delivery, processing and transportation of process media at pressures from about 0.001 MPa up to 100 MPa (inclusive). It also covers pipelines for heat‑transfer fluids, lubricants and other service media necessary for equipment operation. The rules address factory fabrication of pipeline assemblies, erection and mounting on site, requirements for welded and non‑detachable joints, surface protection and marking, and acceptance testing (hydraulic and pneumatic).

Key topics and requirements

• Definition of types of technological equipment and classification of pipelines by purpose and pressure group.
• Requirements for production of pipeline assembly units, detailing and specification compliance (references to relevant GOSTs for drawings and parts such as GOST 16037‑80).
• Rules for welded and non‑removable joints, allowable procedures, control and inspection of welds.
• Mounting and erection requirements: permissible installation loads on building structures, coordination of mounting loads with structural designers, supports and anchor arrangements.
• Testing and acceptance: hydraulic and pneumatic strength and tightness tests, criteria for acceptance and commissioning of individual equipment and pipeline units.
• Surface protection, anti‑corrosion measures, marking and documentation required for handover.
• Quality control and documentation: requirements for specifications, fabrication records, and acceptance acts signed by commissioning/acceptance commissions.

Typical use and users

Used by process/plant designers, mechanical and piping engineers, construction organizations, site installation teams, welding supervisors, quality and inspection personnel, and regulatory/compliance bodies involved in industrial facilities (chemical, petrochemical, food, pharmaceutical, utilities, etc.). Also used as a historical/reference standard in training and by owners maintaining legacy facilities designed under SNiP rules.

Related standards

Closely related and cross‑referenced documents include earlier SNiP III‑31‑78 (superseded by the 1984 SNiP), various GOSTs for materials and drawing documentation (for example GOST 16037‑80 for detailing), later consolidated SP rules (notably SP 75.13330.2011 which updates/collects SNiP 3.05.05‑84 provisions), and industry RD/VSN documents governing welding journals and testing procedures (e.g., RD 153‑34.1‑003‑01, ВСН 362‑87).

FAQ

Q: What is this standard?

A: SNiP 3.05.05‑84 is a Soviet‑era construction norm (SNiP) titled "Technological equipment and process pipelines" that sets out rules for production, installation, testing and acceptance of technological equipment and industrial pipelines.

Q: What does it cover?

A: It covers scope and classification of technological equipment and pipelines, factory fabrication of pipeline assemblies, requirements for joints and welding, mounting and support arrangements, load coordination with building structures, surface protection, testing (hydraulic and pneumatic) and acceptance procedures for commissioning. The text includes pressure‑range limits and test practices.

Q: Who typically uses it?

A: Designers and engineers of process plants, construction and installation contractors, welding supervisors, quality inspectors, plant owners/operators and regulatory/acceptance commissions — particularly when working with facilities designed or built under SNiP rules or when maintaining legacy installations.

Q: Is it current or superseded?

A: The original SNiP was approved in 1984 and introduced in 1985. Its provisions have been carried forward and in many cases updated or consolidated into later SP rules (notably SP 75.13330.2011), so for current regulatory practice users should consult the applicable modern SP documents while SNiP 3.05.05‑84 remains a key historical reference.

Q: Is it part of a series?

A: Yes — it belongs to the SNiP series of construction norms (branch 3.05.* covering building services and industrial systems). It replaced earlier SNiP III‑31‑78 in its subject area and later its provisions were folded into SP documents.

Q: What are the key keywords?

A: Technological equipment, process (technological) pipelines, installation, welding, hydraulic testing, acceptance, Gosstroy, SNiP, SP 75.13330.2011, GOST 16037‑80.
