GOST 12619-78 PDF

Full title and description

GOST 12619-78 — "Днища конические отбортованные с углами при вершине 60 и 90°. Основные размеры" (English: "Conical heads with knuckle, apex angles 60 and 90 degrees. Basic dimensions"). The standard defines the construction and main dimensional tables for flanged (turned-over) welded conical heads with apex angles of 60° and 90°, intended for vessels and apparatus operating under pressure.

Abstract

GOST 12619-78 establishes standardized geometrical forms, designation examples, dimensional tables and basic requirements for manufacture of flanged welded conical heads (with knuckle) in carbon and alloy steels for pressure equipment. It includes construction drawings, tables of nominal diameters and corresponding heights/radii/thicknesses, rules for designation and references to thickness calculation rules.

General information

Scope

The standard applies to flanged (отбортованные) welded conical heads made of carbon and alloy steels with apex angles 60° and 90°, intended for use on pressure vessels and apparatus. It covers basic dimensions, constructive forms for heads with external and internal base dimensions, recommended wall thickness ranges and examples of conditional designation for standard sizes.

Key topics and requirements

• Constructional forms and drawings for conical heads with knuckle (illustrative figures for external and internal base dimensions).
• Dimensional tables for standard nominal diameters: height, knuckle radius, flange height, recommended thicknesses, surface area, volume and approximate mass (separate tables for 60° and 90° apex heads).
• Material scope: carbon and alloy steels; specified allowable thickness series for alloy-steel heads (examples include 5, 7, 9, 11, 13, 15, 17, 19, 21, 26 mm as permitted).
• Thickness calculation: wall thicknesses are to be verified/calculated according to referenced calculation rules (e.g., GOST 14249‑89) with allowance for corrosion and stamping allowance.
• Designation rules and examples (format: e.g., "Днище 60‑530‑8 ГОСТ 12619‑78" to indicate apex angle, nominal diameter and thickness).

Typical use and users

Manufacturers and fabricators of pressure vessels, boilers, storage tanks and related pressure equipment; mechanical designers and engineers specifying standard heads for vessels; procurement and quality-control specialists ensuring compliance with GOST dimensional and material requirements; steelworks and metalwork shops producing stamped or welded heads. The standard is widely used by industry suppliers and fabricators of conical heads.

Related standards

Closely related standards in the GOST series include GOST 12620-78 and GOST 12621-78 (other conical head types and dimensions), and calculation/strength standards referenced for thickness and pressure design such as GOST 14249-89. The 1978 edition replaced earlier versions (for example, GOST 12619-67 and GOST 12621-67).

FAQ

Q: What is this standard?

A: GOST 12619-78 is a USSR/Russian national standard that specifies the basic dimensions, constructive forms and designation rules for flanged welded conical heads with knuckle and apex angles of 60° and 90°, intended for pressure vessels and similar equipment.

Q: What does it cover?

A: It covers constructional drawings, dimensional tables (for external and internal base dimensions), recommended thickness ranges and example designations, plus references to calculation rules for wall thickness (e.g., for corrosion allowance and stamping allowance).

Q: Who typically uses it?

A: Pressure-vessel manufacturers, metal fabricators, mechanical designers, quality inspectors and procurement teams that specify or produce conical heads for tanks, boilers and process vessels. Vendors of tank heads and engineering shops commonly refer to this GOST when supplying or ordering standard heads.

Q: Is it current or superseded?

A: Public databases and standards distributors list GOST 12619-78 as the active (in-force) document; it was introduced into force on 01 January 1980 and has later reprints/editions and amendments recorded in standard collections. Users should verify the latest status in an official national standards database before final design use.

Q: Is it part of a series?

A: Yes — it is part of a set of GOST documents that standardize heads/dished ends and related machine parts (related GOSTs include 12620‑78, 12621‑78 and others); the 1978 standard consolidated and replaced earlier GOST variants from the 1960s.

Q: What are the key keywords?

A: Conical head, knuckle, apex angle 60°, apex angle 90°, flanged head, pressure vessel head, dimensions, thickness, welded head, ГОСТ 12619‑78.
