GOST 22897-86 PDF

Full title and description

Seamless cold-deformed pipes from alloys based on titanium — specifications and technical requirements for manufacture, dimensions, mechanical properties, surface quality and testing of cold‑drawn and cold‑rolled titanium alloy tubes.

Abstract

This standard (GOST 22897-86) defines technical conditions for seamless cold‑deformed (cold‑drawn and cold‑rolled) pipes made from titanium and titanium‑based alloys, including permitted alloys, dimensional and geometric tolerances, surface‑quality categories, mechanical property requirements at specified temperatures, special limits for hydrogen content for high‑quality surfaces, and referenced test and inspection methods.

• Publication date: Introduced 01 January 1988 (approved 1986, put into effect 1988-01-01).
• Publisher: Interstate standard approved by the USSR State Committee for Standards (Gosstandart / Interstate Council for Standardization).
• ICS / categories: Pipes and pipeline components; commonly classified under ICS 23.040.15 (fluid systems and components / pipeline components) in legacy records.
• Edition / version: Original designation GOST 22897-86 (with amendments introduced in later bulletins — e.g., amendments recorded in 1993 and 2001).
• Number of pages: Listed variably in public catalogs (commonly shown as 9 pages or 11 pages in different sources — reference catalogs report 9–11 pages).

Scope

Applies to seamless cold‑deformed (cold‑drawn and cold‑rolled) tubes produced from commercially pure titanium and specified titanium alloys (examples: VT1‑0, PT‑1M, PT‑7M, OT4), setting requirements for permitted chemical composition (by reference to alloy standards), dimensional and tolerance ranges, surface‑quality categories, permissible hydrogen levels for high‑quality surfaces, mechanical properties at specified temperatures, testing and marking. The standard was intended for industries requiring lightweight, corrosion‑resistant and high‑strength tubing (e.g., aerospace, chemical, shipbuilding and specialized engineering).

Key topics and requirements

• Permitted materials and reference to alloy chemical‑composition standards (e.g., VT1‑0, PT‑1M, PT‑7M, OT4).
• Dimensional ranges and tolerances for outer diameter, wall thickness and length; limits on ovality, wall‑thickness variation and curvature.
• Surface‑quality categories (conventional and enhanced surface quality) and associated hydrogen content limits for enhanced surfaces.
• Mechanical-property requirements (tensile strength, yield strength, elongation) specified at room and elevated temperatures for designated alloys.
• Inspection, testing and acceptance procedures: sampling, dimensional inspection, mechanical testing, and references to related GOST test methods.

Typical use and users

Used by pipe manufacturers, metallurgists, quality and inspection engineers, procurement specialists and design offices in aerospace, chemical and process industries, shipbuilding, cryogenic and specialized equipment manufacturing where titanium tubing is required for corrosion resistance, strength‑to‑weight performance and specific temperature applications. Also used by standards libraries and conformity/quality bodies referencing titanium tubing specifications.

FAQ

Q: What is this standard?

A: GOST 22897-86 is a Soviet‑era / interstate standard specifying technical requirements for seamless cold‑deformed pipes made from titanium and titanium‑based alloys.

Q: What does it cover?

A: It covers permitted alloys, dimensional and geometric tolerances, surface‑quality classes, limits on hydrogen for high‑quality surfaces, mechanical properties at specified temperatures, and required inspection and testing procedures for cold‑deformed titanium tubing.

Q: Who typically uses it?

A: Manufacturers and suppliers of titanium tubing, design and engineering teams in aerospace, chemical/process, shipbuilding and specialized equipment industries, and quality/inspection laboratories. Standards departments and procurement teams also reference it when specifying titanium pipes.

Q: Is it current or superseded?

A: Superseded — GOST 22897-86 has been replaced by a newer edition, GOST 22897-2023; users should consult the 2023 edition for current requirements.
