Legislation and Standardization of Piping within Europe

Reasons for application DIN EN 13480

Basis pipe classes, valid in Europe

Aim of pipingdesign and the procurement


Legislation and Standardization within Europe

New laws and technical standards in

Europe,

PED, TA – Luft in Germany

Therefor new standards have to be

established

National standards had to be withdrawn

The piping components according to the

new European standards have not

been available at the market yet.


Present situation in Europe

European Solution:

EN 13480 metallic industrial piping

Possible (national) Solutions:

AD 2000 (Germany)

PD 5500 (Great Britain)

Codap (France)

ANSI petrochemical industrie

Harmonized solution,

Almost no application in Europe due to

the situation at the market


Reasons for application DIN EN 13480 Valid in completely Europe

EN standards in the connection dimensions compatibly to DIN (AD 2000) used within

germany until now

TA-Luft can be solved by using EN 13480


Example: Flanges as construction unit of tubing classes

DIN EN 1092

• Ratings

• Flange contact face form

• Materials

DIN EN 1591 Teil 1

• Calculation

• „Utilization rate“

• Flange shaping

• Tightness/leakage rateprEN 13555

• Yield factors

• Tests

•Classes of tightness

DIN EN 1514

• Gasket dimensions

• Gasket types

DIN EN 1515

• Selection of screws/nuts

• Material combinations

DIN EN 1591 Teil 2

• Yield factor


DIN EN 1092-1: Flanges and their joints- Circular flanges for pipes, valves, fittings and accessories

part 1: steel flanges, described after PN

Designations and roughness of the sealing surfaces changed

Partial changes of measure with sheet thicknesses, sealing surfaces

etc..

The sealing strip projection measure of f1, EN 1092-1 changes to the

past flange standards Pn10-pn63

Pressure/temperature allocations for flanges from ferritic, austenitic

and austenitic-ferritic steel were reduced.

Piping Material Class Data


Basis pipe classes firmspreading compile

All companies must react to the situation

Everyone should compile its firm solution alone

Know-how bundling

Cost advantage by division task treatment

Uniform occurrence at the market

Common “roadmap" to the conversion at the market

Establishing commonPipe Classes,valid in Europe

=>


GVC Working group pipes in cooperation with DIN

(Bayer, BASF, Cognis, Degussa, Siemens, Wacker Chemie, Uhde,

Linde)

Aims:

Arrangement and conversion of common computation and

classification boundary conditions for pipe classes

- Resemble boundary conditions, conceptualnesses

(dimensions, design criteria, materials, etc..)

- Definition on firmspreading basis pipe classes

Formation of a working group


Aim of pipingdesign and the procurement

Uniform planning philosophy in Europe after a set of rules

Law-conformal pipe classes for completely Europe on uniform

basis

Concurrent fulfilment of national special requirements

e.g. tightness requirements

All construction units on a European-wide market available

increase the amount of available stored units by decreasing the

amount of types
