GOST 10705-80 PDF

Full title and description

GOST 10705-80 — "Electrically welded steel tubes. Specifications" (Russian: ГОСТ 10705-80, Трубы стальные электросварные. Технические условия). National / interstate standard that specifies technical requirements, assortment, testing and acceptance rules for electrically welded (ERW and similar) steel tubes used in pipelines, structures and general engineering applications.

Abstract

This standard defines the range, technical requirements, mechanical and chemical property groups, dimensional tolerances, inspection and testing methods, marking, packaging, transportation and storage rules for electrically welded steel tubes with outside diameters typically from 10 mm up to 630 mm. It establishes requirements for weld quality, allowable surface defects, heat treatment options, hydraulic and mechanical tests (flattening, bend, impact where required), and references related normative documents for materials and test methods. GOST 10705-80 has been reissued with multiple amendments and remains a baseline normative reference in the CIS region for welded steel tubing.

Scope

Applies to electrically welded steel tubes manufactured from carbon and low-alloy steels for general-purpose pipelines, structural applications and industrial products. Covers tubes of circular, square and rectangular cross-sections within the standard's dimensional range (commonly Ø 10–630 mm for round tubes), and sets rules for types of production, heat treatment, mechanical properties groups, and the tests required for acceptance. The standard does not cover some special-purpose corrosion-resistant or pressure-service seamless tubes where other standards apply.

Key topics and requirements

• Assortment and dimensions: types, nominal diameters and wall-thickness ranges; dimensional tolerances referenced to GOST 10704 (assortment).
• Material grades and chemical composition: permitted carbon and alloying ranges, references to GOST 1050, GOST 380 and other material standards.
• Mechanical property groups: classification of tubes by groups (A, B, In, D etc.) with specified tensile and impact requirements where applicable.
• Weld quality and repair: requirements for weld soundness, permissible repair welding, reinforcement limits and non-destructive inspection practices.
• Tests and inspection: mandatory tests (hydraulic pressure, flattening, bend, impact — when required), sampling plans, and acceptance criteria for defects.
• Surface condition and permissible defects: limits on cracks, laps, laps, scabs, seams, nicks and other surface imperfections; allowable minor imperfections that do not reduce wall thickness beyond tolerances.
• Heat treatment: options for full-volume or local heat treatment of pipe or welds; requirements for thermomechanical processing where specified by grade or application.
• Marking, packing, transport and storage: marking content and methods, packaging rules and storage/transport conditions referenced to GOST 10692.

Typical use and users

Manufacturers of welded steel tubing, steel pipe mills, quality and metrology departments, procurement and specification engineers, pipeline and structural designers, fabricators and contractors working in oil & gas, construction, mechanical engineering and general industry across countries that use or recognize GOST-derived standards. Also used by testing laboratories and conformity assessment bodies for acceptance testing and certification of welded tubes.

FAQ

Q: What is this standard?

A: GOST 10705-80 is the national/interstate standard that sets technical conditions and acceptance requirements for electrically welded steel tubes (pipes) used for pipelines, structural and general engineering purposes.

Q: What does it cover?

A: It covers assortment (dimensions and tolerances), material grades and chemistry, mechanical property groups, welding and weld-repair requirements, required tests (hydraulic, flattening, impact/bend where applicable), allowable surface defects, heat-treatment options, and marking/packing/transport rules.

Q: Who typically uses it?

A: Tube and pipe manufacturers, quality control and testing laboratories, procurement and specification engineers, fabricators and contractors in industries that source or specify welded steel tubes within territories that apply GOST standards (e.g., Russia and several CIS countries).

Q: Is it current or superseded?

A: The base document is GOST 10705-80 (1980). It has been reissued and maintained with a series of amendments (up to Amendment No. 8) and a 2008 reissue; it remains in force where national implementation lists it as active. For specific, up-to-date legal status in a given country or application you should check the national standards body (Rosstandart or relevant interstate registry) for the current consolidated text and any later replacements.

Q: Is it part of a series?

A: Yes — GOST 10705-80 is part of a family of pipe and tube standards (for example GOST 10704 for assortment of welded tubes, GOST 10706 for related line-weld tubes, and other GOST/GOST‑R standards covering seamless, corrosion-resistant and special-purpose tubes). It is commonly used together with related normative documents for materials, testing and marking.

Q: What are the key keywords?

A: Electrically welded, welded steel tubes, GOST 10705-80, welded pipe specifications, ERW tubes, pipe testing, dimensional tolerances, weld quality, heat treatment, hydraulic test.
