GOST 10706-76 PDF

Full title and description

GOST 10706-76 — Трубы стальные электросварные прямошовные. Технические требования. (English title: Electrically welded steel line-weld tubes — Technical requirements). National (USSR / GOST) standard that specifies technical requirements, dimensional limits, mechanical properties and testing/acceptance rules for longitudinal (straight-seam) electrically welded steel pipes intended for mainline and general-purpose pipeline use.

Abstract

GOST 10706-76 prescribes manufacture, dimensions, material and mechanical property requirements, weld quality and seam reinforcement limits, end preparation, marking, packing, testing (including hydrostatic and nondestructive inspection) and rules for acceptance and shipment of longitudinal electric-welded steel pipes. Originally approved in 1976 for introduction on 1 January 1978, the standard has been maintained with a series of amendments and remains widely referenced for welded transmission and structural pipes in the GOST system.

General information

• Status: Adopted 1976; maintained in the GOST / Interstate (CIS) system with amendments (commonly listed as an active/valid normative document in product catalogs and standards libraries).
• Publication date: Approved 22 April 1976; introduced (date of effect) 1 January 1978.
• Publisher: USSR State Committee for Standards (Gosstandart); subsequently maintained under the GOST / Interstate standards framework and by successor national standardization bodies in CIS countries.
• ICS / categories: 23.040.10 (Iron and steel pipes) — pipeline components and pipelines.
• Edition / version: Original designation GOST 10706-76 with Amendments No. 1–4 (amendments adopted in the 1980s–1990s; Change No.4 adopted by interstate council in 1997; text reissues and extensions appeared through the 1990s and later updates to national catalogues).
• Number of pages: Common published copies list 8–9 pages (published normative text is compact; translations or compilations may vary).

Scope

The standard covers longitudinal (straight-seam) electrically welded steel pipes of circular cross-section intended for mainline and general-purpose use. It sets requirements for range and sizes, permitted steel grades, mechanical properties, seam quality and reinforcement, permissible surface defects, end preparation (beveling/chamfer), marking, packing, transportation and acceptance testing (including hydraulic tests and nondestructive examination). Nominal diameter ranges normally cited in the text are in the large-diameter line-pipe class (commonly referenced 478–1420 mm in many editions; some later catalogs and editions note extended assortments by amendment or by cross-reference to related GOSTs).

Key topics and requirements

• Applicability to longitudinal (straight-seam) electrically welded steel line pipes and general dimensional/assortment limits for large-diameter pipes.
• Material and mechanical-property requirements for base metal (tensile strength, yield, elongation) by steel grade and intended use (including tougher requirements where specified).
• Weld seam quality: requirements for internal and external seam reinforcement, limits on reinforcement height, and provisions for repair of welding defects.
• Non-destructive testing and inspection: provisions for visual inspection, ultrasonic or radiographic inspection of welds where required, and acceptance criteria for defects.
• Hydrostatic (hydraulic) testing requirements and test pressures for acceptance testing of completed pipes.
• End preparation and beveling dimensions (chamfer angles and land widths) to ensure compatibility for field joining and welding.
• Marking, packaging, transportation and storage rules (including required marks on each pipe such as size, grade, year, manufacturer and standard designation).
• Limits on permissible surface imperfections (cracks, laminations, slivers) and rules for permissible minor damages and allowable repair procedures.

Typical use and users

Primary users include pipe manufacturers and mills that produce longitudinal welded line pipe, pipeline engineering and construction companies (oil & gas transmission, water and district heating mains), procurement/specification engineers, testing and quality control laboratories, certification bodies and regulatory authorities in countries that reference or apply GOST standards. The standard is used when procuring welded large-diameter steel pipes or when assessing conformance of such products to GOST technical requirements.

Related standards

Closely related GOST/Interstate standards and normative documents include standards for welded tube specifications and ranges (for example GOST 10704, GOST 10705 series), standards covering marking and packaging (GOST 10692 and others), material standards for carbon and low-alloy steels used for pipes, and interstate/CMEA documents referenced in the original text (СТ СЭВ 489−77). Modern national/regional pipeline and line-pipe standards (ISO, EN, GOST-R / GOST IEC family documents) are often cross-referenced depending on application and regulatory jurisdiction.

FAQ

Q: What is this standard?

A: GOST 10706-76 is a GOST (USSR / interstate) standard titled "Трубы стальные электросварные прямошовные. Технические требования" — it defines technical requirements for longitudinal (straight-seam) electrically welded steel pipes.

Q: What does it cover?

A: It covers dimensions and assortment, permitted steel grades and mechanical properties, weld seam quality and limits, end preparation, marking, packaging, inspection and testing (including hydrostatic and nondestructive tests), and acceptance rules for longitudinal electric-welded steel pipes typically used for mainline and general-purpose pipeline applications.

Q: Who typically uses it?

A: Pipe manufacturers, pipeline constructors and operators (oil & gas, water, heating), procurement and specification engineers, QA/QC and inspection laboratories, and certification/standards bodies in jurisdictions that reference GOST standards.

Q: Is it current or superseded?

A: The standard was approved on 22 April 1976 and introduced on 1 January 1978. It has been reissued and maintained with Amendments No.1–4 (adopted across the 1980s–1990s) and appears in many standards catalogs and product specifications as a referenced active document. Implementing or procurement users should verify the required edition and any national or project-specific replacements (some countries or projects may require more recent national or international standards for specific pipeline applications).

Q: Is it part of a series?

A: Yes — GOST 10706-76 is part of the family of GOST standards for welded steel pipes and tubes (for example GOST 10704, GOST 10705 and related documents) and was prepared in the context of ST SEV 489−77 (the CMEA/Interstate alignment). It is commonly used together with material, testing and packaging GOSTs referenced in its normative section.

Q: What are the key keywords?

A: Electrically welded, straight-seam, line-weld pipes, steel pipes, technical requirements, weld quality, hydrostatic test, marking, beveling, GOST 10706-76, ST SEV 489-77.
