Full title and description

STB DIN EN ISO 1127 2019-03 — Stainless steel tubes — Dimensions, tolerances and conventional masses per unit length. National publication/adoption of DIN EN ISO 1127 as issued March 1, 2019; specifies standard outside diameters, wall thicknesses, permissible deviations and tabulated conventional masses for stainless steel tubes (austenitic, ferritic and martensitic types).

Abstract

This standard defines the standardised outside diameters and wall thicknesses for stainless steel tubes, the associated dimensional tolerances and the conventional masses per unit length. It provides tables of nominal sizes and corresponding conventional masses and gives normative references for selecting diameters and greater wall thicknesses. The document is a national edition based on the EN/ISO text republished by DIN in 2019.

Scope

The standard applies to stainless steel tubes and specifies nominal outside diameters, standard wall thicknesses, dimensional tolerances and conventional masses per unit length. Diameters and thicknesses are taken from established ISO series (ISO 4200 for diameter selection where applicable); the standard tabulates masses for austenitic and for ferritic/martensitic stainless steels and provides the permissible dimensional deviations for production and inspection. The document is intended as the national adoption of the EN/ISO text and does not change the technical content of the underlying ISO 1127:1992 specification.

Key topics and requirements

• Standard nominal outside diameters for stainless steel tubes (series derived from ISO 4200).
• Standard wall thicknesses and alternative thickness selection guidance for larger thicknesses.
• Dimensional tolerances (outside diameter and wall thickness tolerances) for manufacturing and inspection.
• Tables of conventional masses per unit length for austenitic and for ferritic/martensitic stainless steel tubes.
• Reference and normative relations to the underlying ISO/EN publications and prior DIN editions.

Typical use and users

Mechanical designers, process and plant engineers, tube manufacturers, procurement specialists, quality and inspection personnel, and standards librarians use this standard to specify and verify stainless steel tube dimensions and masses for instrumentation, piping, process equipment and general engineering applications where standardised tube sizes and tolerances are required.

Related standards

Key related documents include ISO 1127:1992 (international text), EN ISO 1127 (European adoption), ISO 4200 (selection of outside diameters), and earlier or parallel DIN tube standards (historical DIN 2462 / DIN 2463 series). Users should check national catalogues for any later amendments or related EN/DIN documents for tube materials, testing and fittings.

FAQ

Q: What is this standard?

A: It is the DIN national publication of EN/ISO 1127 (issued March 1, 2019) that specifies standard outside diameters, wall thicknesses, tolerances and conventional masses per unit length for stainless steel tubes.

Q: What does it cover?

A: It covers nominal tube outside diameters and wall thicknesses, permissible tolerances, and tabulated conventional masses for austenitic and for ferritic/martensitic stainless steel tubes; it points to ISO 4200 for diameter selection where larger sizes or thicknesses are needed.

Q: Who typically uses it?

A: Tube and pipe manufacturers, mechanical and process engineers, procurement and QA/QC teams, and standards administrators use it to specify, produce and verify stainless steel tubes for industrial and engineering applications.

Q: Is it current or superseded?

A: The DIN EN ISO 1127:2019-03 publication is the current national edition of the EN/ISO text as republished in March 2019. The underlying ISO edition is ISO 1127:1992 (the international technical content), and users should check for any subsequent amendments or newer ISO/EN revisions if absolute latest international changes are critical.

Q: Is it part of a series?

A: Yes — it is part of the family of tube standards (ISO/DIN/EN) dealing with metallic tubes; it references and aligns with ISO 4200 for diameter selection and relates to historical DIN tube standards (e.g., DIN 2462/2463) and other EN/ISO series covering materials, tests and fittings.

Q: What are the key keywords?

A: Stainless steel tubes, dimensions, tolerances, conventional mass, outside diameter, wall thickness, ISO 1127, DIN EN ISO.
