1. GENERAL 1.1 Scope

This specification aims at the definition of minimum design and manufacturing requirements for Standard or Project Company valves.

Block valves installed on pipelines are not covered by this specification (see 03520.PIP.MEC.FUN).

This specification applies to valves with the following ends:

- threaded or socket welded (from ND ¼" to 3");

- flanged or butt weld (from ND ½" and greater);

- wafer type (butterfly, check and duo-check ND ≥ 2").

The Company Normalization restricts the use of threaded and socket welded ends up to ND 1"1/2.

Though among the reference documents are listed some EN normative, referred to in some Data Sheets for valves not covered by other normative, this specification is applicable only in countries and to projects which do not apply the requirements of European Directive 97/23/CE (PED). In order to use this specification in Europe, it must be integrated with additional PED minimum requirements.

2.7 Requirements for Quality Management and Quality Assurance

Possible Requirements for Quality Management and Quality Assurance will be included in the applicable management specification, attached to the offer.

2.8 Additional requirements for review

2.8.1 Tests

Valves and their parts shall be submitted by Contractor to all tests and verifications specified in the Inspection Data Sheet (IDS), notably:

a) verification of chemical analysis and mechanical properties of the materials;

b) dimensional check;

c) visual examination of castings in accordance with MSS SP-55 code;

d) pressure test of body and bonnet;

e) hydraulic tightness test with closed valve;

f) pneumatic tightness test of seats and backseat;

g) BW ends of cast valves with ND ≥ 2” shall always be 100% radiographed in accordance with ASME code B16.34;

h) BW ends of all forged and cast valves with ND ≤ 1”½ shall always be

submitted to 100% ultrasonic examination in accordance with ASME code B16.34.

The test procedures specified at points d), e), and f) shall be in accordance with the following codes:

(70)

The quantity of pieces to be submitted to hydraulic and pneumatic tightness test (excluding the supplementary tests) is as follows:

VALVES TO BE TESTED Rating Quantity ≤ 800# for ND ≤ 14” Q= N ≤ 800# for ND ≥ 16” ≥ 900# for all ND 100 % where:

N number of pieces relating to each item of the purchase order;

Q test quantity; it shall be rounded as follows:

- - to the superior unit for values ≥ 0.5

- - to the inferior unit for values < 0.5

Any test with negative result shall require an additional test on a double number of pieces belonging to the same lot (lot means a group of valves of the same constructive type, diameter, rating and materials submitted for testing). As an alternative to double testing, the Contractor may submit for testing a new lot of new valves. Finished and unfinished single components of valves rejected during the tests inspection may not be used again. The new lot shall be submitted, after a new heat treatment, to all tests as previously established, without taking into account the results of the first testing execution.

2.8.2 Supplementary tests

The supplementary tests shall be expressly requested in the Data Sheet MOD.MEC.VLI.001.

This document reports a series of supplementary tests and relevant combinations, and defines the nature and type of sampling with their identification codes, which shall be indicated on the valve name plate.

2.8.2.1 Types of supplementary tests

Supplementary test No. 1 (P.S.1)

Radiographic examination of flange welding to the valve body. The quality of the welding shall comply with ASME code B31.3 relevant to butt welded flanges.

Magnetic particle inspection or liquid penetrant examination of the complete valve body and cover surface. The execution procedure for magnetic inspection shall comply with ASTM code E 709 and ASTM code A 275; the acceptance classes shall comply with ASME code B16.34

(71)

The execution procedure for liquid penetrant examination shall comply with ASTM code E 165 and the acceptance classes shall comply with ASME code B16.34 appendix D.

A Liquid penetrant examination shall be carried out whenever it is not feasible to perform magnetic particle examination.

Radiographic examination, in accordance with ASTM code E 94 and ASTM code E 42, of valves body and bonnet casting limitedly on the points indicated in Fig. 31. The radiographic quality level shall be 2-2T (in accordance with ASME B16.34 appendix B). The radiographic samples shall comply with ASTM E 71, ASTM E 446, ASTM E 186 and ASTM E 280.

When it is requested that radiographic examination be extended to the whole body and bonnet surfaces for all the valves relevant to a position order, the identification codes shall be “S” and “T”.

Impact test of valves to be used at low temperatures. Test temperatures and procedures are those specified in the codes relevant to the materials composing each valve, or those specified case by case by Company.

Q number of pieces to be submitted to inspection and testing; its value

shall be rounded up as follows:

- to the next higher figure for values ≥ 0.5

- to the next lower figure for values < 0.5

N number of pieces relevant to each order position.

If the number of pieces is submitted to testing in several groups, the total quantity to be sampled will always be the one relevant to the identification code.

The Company’s Representative is responsible for subdividing the quantity proportionally to the number of pieces submitted during the test.

When the piece shape or the location of the zones to be radiographed does not allow to get radiographies of clear interpretation a supplementary test P.S.2 shall be carried out.

Appendix 1: Identification criteria for valves Identification criteria for Normalized valves

The identification of a valve element belonging to the Eni Internal Normalization is the symbol "AG" in the "Company Symbol."

Example of designation VS 1 1 3 AG 1C1 RF 12

Type Category

Body material group Rating Company symbol Characteristics and materials Valve ends Nominal diameter

Identification criteria for “project” valves

The identifying characteristic of a valve created "for a project" is the symbol "PR" in the " Company Society

Example of designation VS 1 1 3 PR 1Cn RF 12

Type Category

Body material group Rating Company symbol Characteristics and materials Valve ends Nominal diameter

The experts will draw up the description of the mechanical design of the valve completely, leaving the Internal Normalization central units the definition of "n", which will be assigned progressively taking into account the needs of previous projects.

characteristics and materials:

Three alpha-numeric symbols will be used for defining :

- EXECUTION: together with category, it allows to find the

constructive form (e.g.: Category = 5, Execution = 1 means 5.1)

- BODY/BONNET MATERIAL

Usually have the following meaning: C = Carbon Steel

D = Low Temperature Carbon Steel G = F11 J = Nickel Alloy 625 N = AISI 304 P = AISI 304L R = AISI 316 S = AISI 316L T = AISI 347 U = duplex (casting) V = duplex (forged) Y = Nickel Alloy 20 W = Nickel Alloy 825 X = Cu-Ni Z = Titanium - TRIM MATERIAL valves ends: BW - butt-welded

FF - flanged ANSI/ASME: (flat face)

RF - flanged ANSI/ASME: (raised face)

RJ - flanged ANSI/ASME: (ring joint)
