The Euronorms clearly distinguish the pipe’s area of application. Consequently different standards now exist for pipes used as construction materials, pipelines or for mechanical engineering applications. This distinction was not as clear in the past. For example, the old St.

This quality was also often used for steel structures, however. The info below explains the main standards and steel qualities under the new system of standards.

This standard is designed for pipes used een pressure applications, such as a pipeline.

This is why the associated steel qualities are designated by the letter P for ‘Pressure’. The value that follows this letter designates the minimum yield strength. The subsequent letter designations provide additional information. This applies to allqualities designated by the letter ‘N’ idn the new Euro Standards.

It includes quality and testing requirements overall higher than those specifi Butt-welding pipe fittings – Part 1: Wrought carbon steel for general use and without specific inspection requirements The document specifies requirements for steel butt-welding fittings, namely elbows and return bends, concentric reducers, equal and reducing tees, dished and caps.

Butt-welding pipe fittings – Part 2: Non alloy and ferritic alloy steels with specific inspection requirements; German version EN This European Standard specifies in two parts the technical delivery conditions for steel butt welding pipe fittings elbows, return bends, concentric and eccentric reducers, equal and reducing tees, and caps which are intended for pressure purposes and for the transmission and distribution of fluids and gases.

The part 1 covers fittings of unalloyed steels without specific inspection requirements. The part 2 covers fittings with specific inspection requirements and offers two ways for determining the resistance to internal pressure of the fitting.

Butt-welding pipe fittings – Part 3: Wrought austenitic and austenitic-ferritic duplex stainless steels without specific inspection requirements; German version EN This part of EN specifies the technical delivery requirements for seamless and welded butt-welding fittings made of austenitic and austenitic-ferritic duplex stainless dim and delivered without specific inspection. Butt-welding pipe fittings – Part 4: Wrought austenitic and austenitic-ferritic duplex stainless steels with specific inspection requirements; German version EN This European Standard specifies the technical delivery requirements for seamless and welded butt-welding fittings elbows, concentric and eccentric reducers, equal and reducing tees, caps made of austenitic and austenitic-ferritic duplex stainless steel which are intended for pressure and corrosion resisting purposes at room temperature, at low temperature or at elevated temperatures.

In the case of a harmonised supporting standard for materials, presumption of conformity to the Essential Requirement s ESRs is limited to technical data of materials in the standard and does not presume adequacy of the material to xin specific item of equipment.

Consequently the technical data stated in the material standard should be assessed against the design requirements of this specific item of e to verify that the ESRs of the Pressure Equipment Directive PED are satisfied.
