Pipes of class C Specifies the technical delivery conditions for unalloyed and alloyed except stainless seamless and welded steel pipes. Hot finished structural hollow sections of non-alloy and fine grain steels – Part 1: Flanges and their joints – Circular flanges for pipes, Valves, fittings and accessories, PN designated – Part 4: Welded steel tubes for pressure purposes dni Technical delivery conditions – Part 2: This is why the associated steel qualities are designated by the letter P for ‘Pressure’.

Alloy fine grain steel tubes specifies the technical delivery conditions for welded tubes of circular cross section, made of weldable non-alloy fine grain steel This Part of dn European Standard specifies the technical delivery conditions in two test categories for seamless tubes of circular cross-section made of 10235-2 including creep resisting steels and austenitic-ferritic stainless steel which are applied for pressure and corrosion resisting purposes at room temperature, at low temperatures or at elevated temperatures.

Non alloy and alloy steel tubes with specified elevated temperature properties; German version EN Welded steel tubes for pressure purposes – Technical delivery conditions – Part 1: Pipes of requirement class B This European Standard specifies the technical delivery conditions for seamless and welded steel pipes for the on land transport of combustible fluids primarily in gas supply systems but excluding pip 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.

EN Part 1: The EN comprises several parts.

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.

Pipes of requirement class A This European Standard specifies the technical delivery conditions for seamless and welded steel pipes for the on land transport of combustible fluids primarily in gas supply systems but excluding pip It includes quality and testing requirements overall higher than those specifi The part 2 covers fittings with specific inspection requirements and offers two ways for determining the resistance to internal pressure of the fitting.

Electric welded non-alloy and alloy steel tubes with specified elevated temperature properties specifies the technical delivery conditions in two test categories of electric welded tubes of circular cross section, with specified elevated temperature properties, made of non-alloy and alloy steel Steel pipes for pipelines for combustible fluids – Technical delivery conditions – Part 2: Steel pipes for pipe lines for combustible fluids – Technical delivery conditions – Part 3: This applies to allqualities designated by the letter ‘N’ in the new Euro Standards.

The info below explains the main standards and steel qualities under the new system of standards.

Hot finished structural hollow sections of non-alloy and fine grain steels – Part 2: The value that follows this letter designates the minimum yield strength. Welded steel tubes for pressure purposes – Technical delivery conditions – Part 4: In contrast to TR1, for which this is not specified. Tolerances, dimensions and sectional properties This part of EN specifies tolerances for cold formed welded circular, square and rectangular structural hollow sections, manufactured in wall thicknesses up to 40 mm, in the following size range Flanges and their joints – Circular flanges for pipes, Valves, fittings and accessories, PN designated – Part 3: The part 1 covers fittings of unalloyed steels without specific inspection requirements.

Seamless steel tubes for pressure purposes – Technical delivery conditions – Part 4: This standard is designed for pipes used in pressure applications, such as a pipeline. Technical delivery conditions This part of this European Standard specifies technical delivery conditions for hot finished hollow sections of circular, square, rectangular or elliptical forms and applies to hollow sections formed Submerged arc welded non-alloy steel tubes with specified low temperature properties specifies the technical delivery conditions in two test categories of submerged arc welded tubes of circular cross section, with specified low temperature properties, made of non-alloy steel Seamless steel tubes for pressure purposes – Technical delivery conditions – Part 3: Non-alloy steel tubes with specified room temperature properties Specifies the technical delivery conditions for two qualities, T1 and T2, of seamless tubes of circular cross section, with specified room temperature properties, made of non-alloy quality steel Steel pipes for pipelines for combustible fluids – Technical delivery conditions – Part 1: Welded steel tubes for pressure purposes – Technical delivery conditions – Part 3: Consequently different standards now exist for pipes used as construction materials, pipelines or for mechanical engineering applications.

For example, the old St.
