GOST 632-80 PDF

Full title and description

GOST 632-80 — "Casing pipes with couplings. Technical conditions." National (Soviet) standard that specifies technical requirements, assortment, acceptance rules, test methods, marking, packing, transportation and storage for steel casing pipes and their couplings used in oil and gas well construction.

Abstract

This standard covers seamless steel casing pipes with types of threaded connections (triangular, trapezoidal, buttress and related premium/metal-to-metal seals), coupling types and bell-and-spigot (no-coupling) joints intended for use in oil and gas wells. GOST 632-80 establishes dimensional assortment, mechanical and chemical requirements, inspection and testing procedures (including non-destructive testing), acceptance rules, and requirements for marking, packaging and storage. The standard was approved in 1980 and introduced into application from 1 January 1983; it was issued with a series of amendments.

General information

• Status: In force / implemented standard from USSR era; edition with Amendments No.1–4 and with its expiration time-limit removed by later resolutions (retained for application in industry alongside newer product-specific standards).

• Publisher: Approved by the State Committee for Standards of the USSR (Gosstandart); originally published by the Standards Publishing House (Izdatel'stvo standartov).
• ICS / categories: Oil and gas drilling tubulars / drilling and production equipment (classified under drilling tubulars codes such as 23.040.10 / OKP 13 2100 in available bibliographic records).
• Edition / version: Designation GOST 632-80 (original 1980 text) with Amendments No.1–4 (subsequent amendments in 1982–1989 reflected in published editions).
• Number of pages: Typical published edition: about 56 pages (electronic/print formats available in standards collections).

Scope

GOST 632-80 applies to the manufacture, inspection and acceptance of steel seamless casing pipes and their couplings used for supporting oil and gas wellbores. The standard defines allowable sizes and wall-thickness assortment for nominal diameters commonly used in the oilfield, the types of threaded connections (including V-threads, trapezoidal threads, buttress and metal-to-metal high-seal connections), and requirements for coupling and bell-and-spigot (no-coupling) joints. It also sets out mechanical and chemical requirements, test methods (including non-destructive examination), marking and packaging rules for supply and storage.

Key topics and requirements

• Assortment (nominal diameters, outside diameters and wall-thickness ranges) for casing pipe grades and executions.
• Allowed thread types and connection forms (triangular and trapezoidal threads, buttress, short and long V-threads, and premium metal-to-metal seals).
• Chemical composition limits for steel (controls on S and P, specified grades).
• Mechanical property requirements (tensile, yield where applicable) and dimensional tolerances.
• Inspection and acceptance rules, sampling plans and specific test methods (including non-destructive testing described in annexes).
• Marking, thread protection, packing, transportation and storage instructions for delivered tubulars.

Typical use and users

Primary users are oil and gas operators, casing and tubular manufacturers, drilling contractors, procurement/specification engineers, testing laboratories and regulatory bodies that manage well-construction materials. The standard is used to specify and verify casing pipe supply for well completion and drilling programs, and by manufacturers to produce pipe to historically recognized Soviet-era technical conditions.

Related standards

GOST 632-80 is commonly referenced alongside more recent or product-specific standards and industry specifications for tubular goods and premium connections (examples in practice include newer GOST revisions and product standards for oilfield tubulars such as later GOST documents and national/adopted ISO/industry standards addressing premium connections and testing). Users typically consult GOST 632-80 together with updated national standards and producer technical specifications when defining modern procurement requirements.

FAQ

Q: What is this standard?

A: GOST 632-80 is a Soviet-era national standard titled "Casing pipes with couplings. Technical conditions" that sets technical requirements for steel casing pipes and couplings used in oil and gas well construction.

Q: What does it cover?

A: It covers the assortment (sizes and wall thicknesses), allowable thread and joint types (triangular, trapezoidal, buttress, premium seals), chemical and mechanical property limits, inspection and testing methods (including NDT), acceptance rules, marking, packaging, transportation and storage.

Q: Who typically uses it?

A: Oil and gas operators, casing manufacturers, drilling contractors, materials inspectors and procurement/specification teams use GOST 632-80 as a technical reference when procuring or manufacturing casing pipe to the standard’s requirements.

Q: Is it current or superseded?

A: The original GOST 632-80 text was approved in 1980 and introduced in 1983 and was published with several amendments. Bibliographic records indicate the standard has had its expiration time-limit removed in regulatory records and remains a referenced technical document in collections, but users should verify whether project specifications call for GOST 632-80 specifically or for later/revised national or industry standards (newer GOSTs or product standards may be preferred for contemporary procurement). Always check the client's or regulator's current specification list.

Q: Is it part of a series?

A: It is part of the family of standards covering tubular products and drilling/production equipment; it replaced GOST 632-64 and historically sits alongside other GOSTs that regulate pipes, threads and testing methods for oilfield tubulars.

Q: What are the key keywords?

A: Casing, couplings, casing pipe, threads (V, trapezoidal, buttress), bell-and-spigot, oilfield tubulars, technical conditions.
