GOST 31844-2012 PDF

Full title and description

GOST 31844-2012 — Petroleum and natural gas industries. Drilling and production equipment. Hoisting equipment. General technical requirements. The standard sets design, manufacturing, testing, marking and documentation requirements for hoisting (running/hoisting) equipment used in drilling and well-completion/production operations.

Abstract

This standard establishes mandatory technical requirements for equipment used in drilling and production hoisting operations (pulleys, blocks, hook assemblies, elevators, swivels, powered swivels, link/adaptor elements, compensators, pressure vessels and piping mounted on hoisting equipment, safety collars, guide carriages, rotating devices used with hoisting operations, etc.). It is an interstate/national adoption aligned with ISO 13535:2000 and defines product specification levels (PSL), load cases, safety/partial‑factor rules and documentation/traceability expectations for PSL 1 and PSL 2 items.

Scope

Applies to the design, manufacture, inspection and quality control of hoisting equipment and their load‑bearing components used in drilling and well operation activities in the petroleum and natural gas industries. The standard covers pulleys for hoisting systems, mobile and fixed blocks, hook suspension assemblies, elevator slings and elevator bodies for casing/production/tubing/ drill‑pipe/rod strings, swivels and powered swivels, powered subs, guide carriages, shock/bumper compensators, pressure vessels and piping assembled on hoisting units, safety collars when used as hoisting devices and related items. It specifies engineering load cases, required safety factors, nondestructive testing, marking and documentation/traceability obligations for load‑bearing parts.

Key topics and requirements

• Definition of product specification levels (PSL 1 and PSL 2) and applicability of additional requirements under PSL 2.
• Design load cases and classification of loading conditions (PLC/LC combinations) with associated minimum factors of safety and required combinations for normal, service and exceptional conditions.
• Material selection, mechanical property requirements and fatigue resistance considerations for load‑carrying components.
• Nondestructive testing and inspection rules for critical parts (welding, surface condition, dimensional checks); special provisions for hardened/ surface‑treated grooves and wheel surfaces.
• Marking, serial numbering and traceability of load‑carrying components and assemblies; requirements for stamping/casting of identification marks and minimum character sizes.
• Documentation and recordkeeping requirements (manufacturer documentation to be retained and made available; typical retention periods specified).
• Testing and acceptance criteria for assemblies and pressure‑containing items mounted on hoisting equipment, including proof/loading tests and checks for functional devices like compensators and powered swivels.

Typical use and users

Used by drilling‑equipment manufacturers, OEMs of hoisting components, rig designers and integrators, drilling contractors, inspection and certification bodies, procurement specialists for oil & gas operators, and regulatory/standards compliance teams responsible for rig and wellsite equipment safety.
