Overview

The prEN 10253-3 standard, titled Butt-welding pipe fittings - Part 3: Wrought austenitic and austenitic-ferritic (duplex) stainless steels without specific inspection requirements, is published by CEN. This document specifies the technical delivery requirements for seamless and welded butt-welding fittings made from austenitic and austenitic-ferritic (duplex) stainless steels. These fittings are supplied without specific inspection protocols, streamlining the supply process while maintaining essential quality standards.

This part of the EN 10253 series is an important reference for manufacturers, suppliers, and end-users of stainless steel pipe fittings used in critical piping systems across multiple industries.

Key Topics

• Material Types
  Focuses on wrought austenitic stainless steels and austenitic-ferritic (duplex) stainless steels, which offer excellent corrosion resistance and mechanical properties suited to demanding environments.

• Fitting Types
  Covers both seamless and welded butt-welding pipe fittings used for joining pipe sections in fluid transport systems.

• Technical Delivery Conditions
  Defines the quality, composition, and dimensional tolerances required for fittings delivered under this standard without specific inspection requirements.

• Exclusion of Specific Inspection
  This standard applies where no additional specific inspection or testing beyond typical manufacturing controls is required, facilitating faster supply chains.

• Surface Treatment and Finish
  Although detailed inspection is not mandatory, the fittings must meet general surface quality and finish criteria to ensure reliability in application.

Applications

• Chemical and Petrochemical Plants
  Austenitic and duplex stainless steel fittings resist aggressive media and high temperatures, making them essential components in chemical processing and petrochemical infrastructure.

• Oil and Gas Industry
  Durability under corrosive conditions and variable pressure environments makes these fittings suitable for pipelines and processing units in the oil and gas sector.

• Water Treatment and Desalination
  The corrosion resistance properties support long service life in systems handling seawater or treated water.

• Food and Pharmaceutical Industries
  The hygienic characteristics and corrosion resistance of austenitic stainless steel make these fittings appropriate for sanitary process pipelines.

• Power Generation
  High temperature capability ensures stable performance in power plants, including nuclear and thermal generation facilities.

Related Standards

• EN 10253-1 and EN 10253-2
  These parts of EN 10253 cover butt-welding pipe fittings made from carbon and low alloy steels, as well as chromium and chromium-nickel steels with specific inspection requirements.
