Technical delivery conditions for steel pipes for use with combustible fluids

Part 1: Pipes of requirement class A

English version of DIN EN 10208-1

Stahlrohre für Rohrleitungen für brennbare Medien – Technische Lieferbedingungen – Teil 1: Rohre der Anforderungsklasse A

European Standard EN 10208-1 : 1997 has the status of a DIN Standard.

A comma is used as the decimal marker.

National foreword

This standard has been prepared by ECISS/TC 29.

The responsible German body involved in its preparation was the Normenausschuß Eisen und Stahl (Steel and Iron Standards Committee), Technical Committee Fernleitungrohre.

This standard is similar in structure to DIN EN 10208-2, from which it deviates in the following respects.

a) Different C, P and S contents have been specified. Specifications for the Cu, Ni, Cr and Mo content have not been included.

b) Less extensive requirements have been specified for pipe manufacture (cf. clause 6).

c) Different values for mechanical strength have been specified.

d) Less stringent requirements have been specified for testing (frequency of testing, hydrostatic strength, non-destructive testing).

It should be noted that this differs considerably from International Standard ISO 3183-1 (which is based on ANSI/API 5L).

DIN V 17006-100 is the standard corresponding to European Standard CEN/CR 10260 referred to in clause 2 of the EN.

This European Standard was approved by CEN on 1997-11-26.

CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the Central Secretariat or to any CEN member.

The European Standards exist in three official versions (English, French, German). A version in any other language made by translation under the responsibility of a CEN member into its own language and notified to the Central Secretariat has the same status as the official versions.

CEN members are the national standards bodies of Austria, Belgium, the Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, the Netherlands, Norway, Portugal, Spain, Sweden, Switzerland, and the United Kingdom.

Foreword

This European Standard has been prepared by Technical Committee ECISS/TC 29 "Steel tubes and fittings for steel tubes" the secretariat of which is held by UNI.

This European Standard EN 10208-1 has been established by ECISS/TC 29/SC 2 "Steel tubes and fittings for steel tubes - Line pipe" in co-operation with ISO/TC 67/SC 1 "Material and equipment for petroleum and natural gas industries - Line pipe" which is responsible for the International Standard for line pipe ISO 3183-1 [1].

This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by May 1998, and conflicting national standards shall be withdrawn at the latest by May 1998.

There are some principal differences between EN 10208-1 and ISO 3183-1 concerning

a) the concept:

This EN 10208-1 covers steel grades of low and medium strength level up to 360 N/mm² yield strength in a basic quality (see introduction).

ISO 3183-1 covers the full range of strength levels up to 555 N/mm² yield strength and provides, in addition to the general requirements which correspond in this case with those of the main part of ANSI/API 5L [2], for agreement at the time of enquiry and order, a series of supplementary requirements also taken from ANSI/API 5L.

b) formal items:

• normative references (see clause 2);
• this European Standard uses steel numbers in accordance with EN 10027-2 (see tables 2 and 4);
• this European Standard uses the standardized code numbers and terms of EURONORM 168 for the structure and the content of inspection documents.

Annex F contains national A-deviations specifying the restrictions for the application of this European Standard in Sweden.

According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.
