GOST 31443-2012 PDF

Full title and description

GOST 31443-2012 — "Трубы стальные для промысловых трубопроводов. Технические условия" (English: "Steel pipes for oilfield (promyslovye) pipelines. Specifications"). The standard specifies technical requirements for seamless and welded steel pipes intended for oil- and gas-field (production / gathering / flowline) pipelines, including material, mechanical properties, testing, inspection, marking, coating and packaging requirements for service down to −60 °C.

Abstract

GOST 31443-2012 establishes product, manufacturing and acceptance requirements for steel pipes used in oilfield/promoislovy pipelines. It covers permitted grades and strength classes, dimensional and geometric tolerances, chemical and mechanical property limits, mandatory and optional tests (mechanical, impact, hydrostatic), non‑destructive examination methods, requirements for sour/acid (H2S) service, marking, traceability, protective coatings and documentation. The standard was adopted in 2012 and introduced for use on 1 January 2014.

Scope

The standard applies to seamless and welded steel pipes intended for use in oil and gas production pipelines (promyslovye pipelines), including flowlines, gathering lines and other field pipeline applications. It specifies requirements for pipes operated at temperatures down to −60 °C. The document covers chemical composition and metallurgical requirements, mechanical properties (tensile, yield), impact and fracture toughness testing at specified temperatures, hydrostatic testing, non‑destructive examination, surface acceptance criteria, marking, coating, packaging and documentation. Special provisions address pipes for acidic (sour) environments and qualification/attestation of manufacturing technology.

Key topics and requirements

• Product scope: seamless and welded steel pipes for oilfield/pipeline use, with defined diameter and wall‑thickness ranges and practical service temperature down to −60 °C.
• Material and strength classes: definitions of strength classes commonly used in the series (examples encountered in the text: КП 245, КП 290, КП 320, КП 360) and corresponding mechanical property limits.
• Chemical composition and heat‑treatment requirements to ensure required mechanical and low‑temperature properties.
• Mechanical testing: tensile tests, bend tests and impact (CVN) tests at specified temperatures; requirements for DWT and fracture‑related testing where applicable.
• Non‑destructive testing and acceptance: ultrasonic inspection, magnetic‑particle inspection, visual control and criteria for handling detected imperfections and laminations.
• Hydrostatic testing and leak/pressure acceptance criteria for deliveries.
• Sour/acid service provisions: additional requirements and limitations for pipes intended for H2S or acidic environments (special designations and treatments such as UTP2 and related controls).
• Dimensional and geometric tolerances, surface defect acceptance and repair/removal rules.
• Marking, traceability and documentation: requirements for durable marking, supply documentation and traceability (batch/heat numbers, MPS/MPQT evidence where required).
• Coating, packing and preservation requirements for transport and storage.
• Manufacturing technology attestation: requirements for attestation/qualification of pipe production technology and initial qualification tests for new sizes/grades (MPS/MPQT procedures).

Typical use and users

Used by pipe manufacturers, pipeline EPC contractors, oil & gas operators, procurement departments, design engineers, inspection and testing laboratories, and certification bodies involved in selection, purchase, manufacture, testing and acceptance of pipes for oilfield and gathering pipeline systems, including projects in low‑temperature and sour service environments.
