GOST 8733-74 PDF

Full title and description

GOST 8733-74 — "Трубы стальные бесшовные холоднодеформированные и теплодеформированные. Технические требования" (English title: "Seamless cold and warm deformed pipes. Specifications"). This national (GOST) standard defines technical requirements for seamless cold‑deformed and warm‑deformed steel pipes intended for general-purpose use.

Abstract

GOST 8733-74 establishes dimensional, mechanical and acceptance requirements, marking and documentation rules, and testing (including hydrostatic testing) for seamless cold‑ and warm‑deformed carbon and alloy steel pipes. It includes provisions on party acceptance, delivery documentation and references to related steel and testing standards. The text incorporates multiple amendments and has been maintained in current collections of GOST standards.

General information

• Status: Active (in force; included in modern GOST collections and catalogs).
• Publication date: Introduced into force 01 January 1976 (designation year 1974 — GOST 8733‑74).
• Publisher: Originally issued as a USSR State Standard (Gosudarstvennyy Standart, GOST); maintained in Russian standards collections and by national standards bodies.
• ICS / categories: Covers pipe and metallurgy categories (OKC/ICS classifications reported: 23.040.10; 77.140.75).
• Edition / version: Original designation 8733‑74 with integrated amendments (noted amendments from 1976, 1980, 1986 and 1992); has been reprinted in later GOST collections (e.g., 2004 reissue referenced).
• Number of pages: Typical published text ~5 pages (may vary by publisher/compilation).

Scope

Applies to seamless cold‑deformed and warm‑deformed (теплодеформированные) seamless steel pipes of general purpose made from carbon and alloy steels. The standard sets requirements for dimensions, material grades (by reference to relevant steel standards), inspection and acceptance, marking, and testing (including hydrostatic pressure tests where applicable). It replaces the earlier ГОСТ 8733‑66 and is intended for manufacturers, suppliers and users of seamless small‑diameter and medium‑diameter pipes.

Key topics and requirements

• Scope and application to cold‑deformed and warm‑deformed seamless pipes (carbon and alloy steels).
• Dimensional tolerances and nominal size ranges for outer diameter and wall thickness (as specified in the standard tables).
• Mechanical property requirements tied to steel grades (references to GOST steel specifications such as GOST 1050 series and others listed in normative references).
• Acceptance rules: batch (party) acceptance, documentation per quality certificate requirements (reference to GOST 10692), and party size limits.
• Testing requirements including hydrostatic testing calculation reference (per GOST 3845) and other quality checks.
• End preparation and beveling requirements for pipes intended for welding (if wall thickness ≥ specified values), marking and delivery documentation.

Typical use and users

Used by steel pipe manufacturers, metal product suppliers, pipeline and mechanical engineers, procurement and quality assurance departments, welders and fabricators specifying pipe ends and preparation, and technical inspectors performing acceptance testing and certification for industrial piping, mechanical assemblies and general‑purpose tubular products.
