Full title and description

STB BS 3605-1-1991 (1997) — National adoption (STB) of British Standard BS 3605-1:1991, "Austenitic stainless steel pipes and tubes for pressure purposes — Part 1: Specification for seamless tubes". The document reproduces the technical requirements, chemical and mechanical property limits, dimensional tolerances, tests and marking requirements of BS 3605-1:1991 as published by BSI and adopted as a Belarusian STB publication in 1997.

Abstract

This standard specifies requirements for austenitic stainless steel seamless pipes and tubes intended for pressure purposes. It covers designation, manufacture of steel and the tube, chemical composition, final supply condition, mechanical properties (including elevated-temperature proof stress values), inspection, tolerances, testing, marking and certificates required for pressure applications. The STB version is a national publication reproducing BS 3605-1:1991.

General information

• Status: Adopted as an STB national publication (listed as active in some catalogues); the original British Standard (BS 3605-1:1991) was later superseded by EN-based specifications.
• Publication date: Original BS publication: 28 February 1991; STB national adoption/publication: 1997.
• Publisher: British Standards Institution (BSI) — original; adopted and published for national use under the STB designation by the Belarusian standards body in 1997.
• ICS / categories: 23.040.10 (Iron and steel pipes); 77.140.75 (Steel pipes and tubes for specific use).
• Edition / version: Part 1 — BS 3605-1:1991; national designation STB BS 3605-1-1991 (1997).
• Number of pages: Approximately 32 pages (BSI publication page count).

Scope

The standard applies to seamless austenitic stainless steel pipes and tubes manufactured for pressure purposes and intended for use at ambient and elevated temperatures. It defines required chemical composition ranges, heat treatment and final supply condition, mechanical property minima (including proof stress at elevated temperature where applicable), dimensional and geometric tolerances, inspection and testing procedures, sample selection and preparation, certificates and marking. The STB adoption reproduces these requirements for national application.

Key topics and requirements

• Designation system for austenitic stainless steel tubes (material designations and steel grades).
• Requirements for manufacture of the steel and seamless tube production methods.
• Chemical composition limits and methods of analysis.
• Mechanical property requirements including tensile properties, proof stress and elongation; includes elevated-temperature proof stress values where applicable.
• Visual inspection, dimensional tolerances and surface/appearance requirements.
• Test methods, number and selection of samples, retest procedures and required test certificates.
• Marking, protective coating and documentation required at delivery.

Typical use and users

Used by manufacturers of seamless stainless steel pressure tubing, material suppliers, design and mechanical engineers specifying pressure piping, inspection and quality assurance personnel, procurement departments and testing laboratories. Typical applications include pressure vessels, piping systems in chemical and petrochemical plants, power generation and process industries where corrosion-resistant austenitic grades are required.

Related standards

BS 3605-1:1991 is part of the BS 3605 family addressing stainless steel pipes and tubes. The original BS 3605-1:1991 has subsequently been superseded in the UK/Europe by EN-based specifications such as BS EN 10216-5 (and later editions), which cover seamless steel tubes for pressure purposes in harmonized EN formats. National STB adoption references the original BS text as published in 1997.

FAQ

Q: What is this standard?

A: It is the Belarusian national adoption (STB) of British Standard BS 3605-1:1991, titled "Austenitic stainless steel pipes and tubes for pressure purposes — Part 1: Specification for seamless tubes", issued as STB BS 3605-1-1991 (1997).

Q: What does it cover?

A: The specification covers seamless austenitic stainless steel pipes and tubes for pressure purposes: designation, manufacture, chemical and mechanical requirements (including elevated-temperature proof stress), inspection, tolerances, tests, certificates and marking.

Q: Who typically uses it?

A: Tube and pipe manufacturers, material and quality engineers, procurement specialists, testing laboratories and plant designers in industries requiring corrosion-resistant pressure piping (chemical, petrochemical, power generation, etc.).

Q: Is it current or superseded?

A: The original British Standard BS 3605-1:1991 was later superseded by EN-based standards (for example BS EN 10216-5 editions). The STB national adoption reproduces the BS 3605-1 text as published in 1997; national catalogues list the STB item but users should check current national/regional regulations and later EN standards for the most up-to-date requirements.

Q: Is it part of a series?

A: Yes — it is Part 1 of the BS 3605 series dealing with austenitic stainless steel pipes and tubes for pressure purposes; other parts and later EN replacements address related products and updates.

Q: What are the key keywords?

A: Austenitic stainless steel, seamless tubes, pressure purposes, chemical composition, mechanical properties, proof stress, elevated temperature, tolerances, testing, marking, STB adoption, BS 3605-1:1991.
