GOST 3706-93 PDF

Full title and description

GOST 3706-93 — "Gate valves. End-to-end lengths" (Russian: "Задвижки. Строительные длины"). The standard specifies the recommended face‑to‑face (end‑to‑end) dimensions for cast iron and steel gate (sluice) valves with flanged and butt‑weld ends and establishes the building lengths used for design and manufacture.

Abstract

This national (interstate) standard defines nominal face‑to‑face (construction) lengths for gate valves intended for pipeline systems. It is used to harmonize valve dimensions across manufacturers and to ensure interchangeability of valves in piping systems, covering typical nominal diameters and pressure classes for flanged and welded end configurations. It does not cover valves of special purpose beyond the general pipeline and industrial applications.

General information

• Status: Active / in force (standard adopted 1993 and widely used for face‑to‑face dimensions; it replaced GOST 3706‑83).
• Publication date: Approved 21 October 1993 (often shown in catalogs with an editorial/publication date of 1 January 1995 for published copies/translations).
• Publisher: Adopted by the Interstate Council for Standardization, Metrology and Certification / national standards bodies publishing GOST documents.
• ICS / categories: 23.060 (Pipeline valves / fittings, hydraulic and pneumatic systems — gate valves and pipeline hardware).
• Edition / version: Original designation GOST 3706‑93 (1993). It supersedes GOST 3706‑83 for face‑to‑face dimensions.
• Number of pages: Typically listed as 10–12 pages depending on the publisher/translation (catalog records commonly show 10 or 12 pages).

Scope

GOST 3706‑93 applies to cast iron and steel gate valves with flanged and butt‑weld ends and establishes the standardized end‑to‑end (face‑to‑face) dimensions used in construction drawings and manufacture. The standard is intended to ensure dimensional interchangeability of gate valves used in pipelines for general industrial, energy, water, heating and similar applications. It explicitly excludes special‑purpose valves that require non‑standard dimensions.

Key topics and requirements

• Standardized face‑to‑face (end‑to‑end) lengths for gate valves by nominal diameter and sometimes by pressure class.
• Applicability to flanged and welded ends (dimensions referenced for both connection types).
• Compatibility with other GOST flange and connection standards (commonly used alongside GOST 12815 for flange dimensions and with valve design standards such as GOST 5762).
• Specification of construction (building) lengths used by manufacturers and designers to ensure interchangeability.
• Reference to prevailing national practice for pipeline valve sizing and installation; used as a dimensional benchmark rather than a material or performance specification.

Typical use and users

Primary users include valve manufacturers, piping and pipeline designers, procurement/specification engineers, OEMs for energy/petrochemical/water sectors, plant maintenance teams, and suppliers exporting or sourcing valves for markets that use GOST dimensions (Russia and many CIS/Eastern European markets). It is used when selecting or manufacturing gate valves to ensure correct installation lengths and interchangeability.

Related standards

Commonly referenced or associated standards include: GOST 3706‑83 (earlier edition replaced by 3706‑93), GOST 5762 (pipeline industrial valve design and specifications), GOST 12815 (flange dimensions), GOST 356 (testing/inspection references), and later pipeline/valve general specifications such as GOST 31901 and other sector‑specific valve standards. These documents are typically used together to cover dimensional, design, flange and testing requirements.

FAQ

Q: What is this standard?

A: GOST 3706‑93 is the Russian/interstate standard that specifies face‑to‑face (end‑to‑end or construction) lengths for cast iron and steel gate valves with flanged and welded ends. It provides dimensional rules to ensure interchangeability.

Q: What does it cover?

A: It covers the standardized end‑to‑end (face‑to‑face) dimensions for gate valves by nominal size and connection type (flanged or butt‑weld). It does not set materials, performance tests or special‑purpose valve dimensions — those are covered in separate design and testing standards.

Q: Who typically uses it?

A: Valve manufacturers, pipeline and mechanical designers, procurement/specification engineers, and suppliers working with GOST‑based technical documentation in Russia and CIS/Eastern European markets.

Q: Is it current or superseded?

A: GOST 3706‑93 is recorded in standards catalogs as the valid reference for gate‑valve face‑to‑face lengths and it superseded the earlier GOST 3706‑83. However, designers often use it together with newer design and product‑specific GOST documents (for example GOST 5762 for valve specifications). Check national standards registries or the purchasing catalog entry for the most recent status in your jurisdiction before final specification.

Q: Is it part of a series?

A: It is part of the family of GOST standards that cover pipeline valves and fittings. It is a dimensional (construction‑length) standard that complements separate GOST documents addressing valve design, materials, testing and flange/connection standards.

Q: What are the key keywords?

A: Gate valve, end‑to‑end length, face‑to‑face, building length, flanged, butt‑weld, GOST 3706‑93, pipeline valves.
