GOST 8967-75 PDF

Full title and description

ГОСТ 8967-75 — Части соединительные стальные с цилиндрической резьбой для трубопроводов Р=1,6 МПа. Ниппели. Основные размеры. (English title: Pipe steel connections with cylindrical thread for pipelines P=1,6 MPa. Nipples. Basic dimensions.)

Abstract

This standard specifies the basic external dimensions, nominal sizes and marking for steel nipples with cylindrical (parallel) thread intended for pipelines with a nominal pressure of 1.6 MPa. It covers uncoated and zinc‑coated steel nipples for use with a sealing material in non‑aggressive media (water, saturated steam, combustible gas, etc.) at temperatures up to 175 °C. Typical nominal diameters range from DN 8 to DN 100 (some sizes produced on request).

General information

• Status: Active (standard in force; restriction of validity lifted in 1991; reissued/republished editions available).
• Publication date: Introduced 01 January 1977 (approved by State Committee decision dated 29 December 1975).
• Publisher: Gosstandart / Interstate standard (USSR origin); maintained in Russian national / regional standards collections.
• ICS / categories: ICS 23.040.40 (pipe fittings / connecting parts).
• Edition / version: Designation -75 (original issue 1975; date of introduction 1977); later reprints and republications recorded (e.g., September 2010 republication noted).
• Number of pages: Short sheet standard (commercial sources list as 1 page / single‑sheet specification).

Scope

Applies to steel nipples with cylindrical (parallel) threads used to connect pipes in heating, water supply, gas and similar pipeline systems where the medium is non‑aggressive and the operating temperature does not exceed 175 °C. The standard establishes main dimensions (thread designation, overall length, mass for uncoated items) for nominal pipe sizes DN 8–100 (with certain sizes shown in parentheses as made on customer request). Rated working pressure for the series is P = 1.6 MPa.

Key topics and requirements

• Basic external dimensions and nominal lengths for nipples by nominal diameter (DN 8–100), with example table of lengths and masses.
• Use of cylindrical (parallel) pipe thread with sealing (thread sealant or tape) for leak‑tight joints in non‑aggressive media.
• Materials and manufacture references — nipples are to be made from steel (with or without zinc coating) and produced from tubes conforming to referenced GOSTs (e.g., GOST 8965‑75, GOST 3262‑75, GOST 10707‑80 as applicable).
• Designation and marking examples (format: e.g., "Ниппель 50 ГОСТ 8967‑75" or "Ниппель 50‑Ц ГОСТ 8967‑75" for zinc plated).
• Intended operating conditions specified (non‑aggressive media, Tmax ≤ 175 °C, P = 1.6 MPa).

Typical use and users

Used by manufacturers of pipe fittings and plumbing components, distributors and wholesalers of pipeline hardware, mechanical and plumbing contractors, industrial maintenance departments and designers of heating, water and gas distribution systems who require standardized nipples for threaded connections at up to 1.6 MPa. End users include building services contractors, utilities and OEMs requiring parts compatible with Soviet/Russian GOST threaded fittings.

Related standards

Commonly referenced companion and predecessor standards include GOST 8965‑75 (parts with cylindrical thread — general requirements), GOST 3262‑75 and GOST 10707‑80 (tube material specifications), and the earlier GOST 8967‑59 which this standard replaced. The standard sits within a family of GOSTs covering threaded pipe fittings and dimensions.

FAQ

Q: What is this standard?

A: ГОСТ 8967‑75 is a Soviet/Russian standard that defines the basic dimensions, nominal sizes and marking for steel nipples with cylindrical (parallel) thread for pipelines rated at P = 1.6 MPa.

Q: What does it cover?

A: It covers external dimensions (lengths, thread designations), mass examples, material/coating options (zinc‑coated or bare steel), operating conditions (non‑aggressive media, Tmax ≤ 175 °C) and designation/marking conventions for nipples used in threaded pipeline connections.

Q: Who typically uses it?

A: Manufacturers of plumbing and pipe fittings, distributors and installers of heating/water/gas systems, engineering designers and maintenance teams who need standardized threaded nipples compatible with GOST fittings.

Q: Is it current or superseded?

A: According to national standards databases and publishers, ГОСТ 8967‑75 is listed as a действующий (active) standard; the restriction on its validity was lifted in 1991 and the document has recorded reprints. Users should verify current national/regional adoption or replacement notices before specifying for new projects.

Q: Is it part of a series?

A: Yes — it is part of a set of GOSTs covering threaded pipe fittings and connecting parts; it replaces GOST 8967‑59 and references related GOSTs for materials and manufacturing (for example GOST 8965‑75, GOST 3262‑75, GOST 10707‑80).

Q: What are the key keywords?

A: Nipple, cylindrical thread, pipe fitting, threaded connection, GOST 8967‑75, P=1.6 MPa, DN 8–100, zinc coating, steel.
