Foreword
This specification was prepared under Joint Industry Programme 33 (JIP33) "Standardization of Equipment
Specifications for Procurement" organized by the International Oil & Gas Producers Association (IOGP) with
the support from the World Economic Forum (WEF). Companies from the IOGP membership participated in
developing this specification to leverage and improve industry level standardization globally in the oil and gas
sector. The work has developed a minimized set of supplementary requirements for procurement, with life
cycle cost in mind, resulting in a common and jointly agreed specification, building on recognized industry and
international standards.
Recent trends in oil and gas projects have demonstrated substantial budget and schedule overruns. The Oil
and Gas Community within the World Economic Forum (WEF) has implemented a Capital Project Complexity
(CPC) initiative which seeks to drive a structural reduction in upstream project costs with a focus on industry-
wide, non-competitive collaboration and standardization. The CPC vision is to standardize specifications for
global procurement for equipment and packages. JIP33 provides the oil and gas sector with the opportunity to
move from internally to externally focused standardization initiatives and provide step change benefits in the
sector's capital projects performance.
This specification has been developed in consultation with a broad user and supplier base to realize benefits
from standardization and achieve significant project and schedule cost reductions.
The JIP33 work groups performed their activities in accordance with IOGP's Competition Law Guidelines
(November 2020).

Introduction
The purpose of this specification is to define a minimum common set of supplementary requirements for the
specification for procurement of the most commonly used materials and to facilitate the manufacture of stock
products to reduce cost and increase availability, for application in the petroleum and natural gas industries.
This specification follows a common document structure comprising the four documents as shown below,
which together with the purchase order, define the overall technical specification for procurement.
JIP33 Specification for Procurement Documents

Technical Specification
Quality and information requirements for the supply of piping and valve components are specified in the
individual material data sheet rather than through separate quality requirements specification (QRS) and
information requirements specification (IRS). Quality and information requirements for piping and valve
components purchased as part of an equipment item are supplemented by the equipment QRS and IRS.
Unless defined otherwise in the requisition, the order of precedence (highest authority listed first) of the
documents shall be:
a) regulatory requirements;
b) contract documentation (e.g. purchase order);
c) user defined requirements (equipment data sheet, equipment IRS, equipment QRS);
d) this specification.
This specification is not intended to preclude the use of alternative generic materials or grades within a
referenced material standard. Where the use of alternative materials/grades are considered appropriate, the
end user is responsible for specifying any additional requirements necessary to meet design and design code
or specification.

1 Scope
This specification is a collection of material data sheets (MDSs) and element data sheets (EDSs) for the most
commonly used components for piping systems and valves for Normal fluid service, Category D fluid service
and High Pressure fluid service as defined in ASME B31.3.
NOTE The scope of IOGP S-563 is design code independent and it is not restricted to piping designed to ASME B31.3.
Supplementary material requirements for services defined in ASME B31.3 as Category M fluid service,
elevated temperature fluid service, high purity fluid service, severe cyclic conditions are excluded from the
scope.
This specification addresses specific minimum requirements for materials exposed to sour environments as
defined in ISO 15156 /NACE MR0175 and ISO 17945 /NACE MR0103. However, this specification does not
provide guidelines for material selection and the selection of suitable materials for a specific service including
any necessary additional material requirements remains the responsibility of the end (equipment) user.
Line pipe material for pipeline systems is outside the scope of this specification.
The material data sheets cover the following material types:
− Non-impact tested carbon steel;
− Impact tested carbon steel;
− Ferritic-austenitic stainless steel: types 22Cr duplex and 25Cr duplex;
− High alloy austenitic stainless steel: type 6Mo;
− Austenitic stainless steel: type 316/316L, type 304/304L, type 321, type 347, type 321H, type 347H;
− Austenitic stainless steel 200-series: grade XM-19;
− Martensitic stainless steel: types 12Cr and 13Cr;
− Copper-Nickel alloys: type 90-10 and aluminium bronze;
− Nickel alloys: types 625 and 825;
− Nickel alloy bolting: types 625 and 718;
− Precipitation-hardened stainless steel: austenitic grade 660 and martensitic grade 630;
− Titanium grade 2;
− High strength, low alloy steels;
− Nickel-alloyed steel: type 3.5 % Ni;
− Cr-Mo alloyed steel: 1¼ Cr ½ Mo and 2¼ Cr 1 Mo grades.
The element data sheets address the following:
− Hard facing by weld overlay;
− Hard facing by thermal spraying;
− Electroless nickel plating;

− Corrosion resistant weld overlay;
− Solid tungsten carbide.

4 Material and element data sheets
4.1 General
The material data sheets (MDSs) are collated in Annex A. They define applicable options and requirements
that supplement or amend the referenced material standard or specification. The material shall be delivered in
accordance with the standard specification referenced in the MDSs including any additional requirements
specified therein. Unless otherwise specified in the MDSs, all the requirements of the referenced standard or
specification shall apply. The latest issue of the referenced standard or specification at the time of purchase
shall apply.
NOTE ASTM standard designations comprising the "M" specification designation for SI units, appear in the MDSs in
an abbreviated form, e.g. ASTM A105/A105M is referenced as ASTM A105 in the MDS.
Welded pipes MDSs specifying acceptance classes give welding quality factors ranging from 0.8 to 1.0
according to ASME B31.3. The required class shall be specified on the piping class sheet and the purchase
order shall specify acceptable class for each relevant item.
The element data sheets (EDSs) are included in Annex B. They define the requirements for special processes
and parts used in connection with manufacturing or assembly of piping and valves. Processes and parts shall
comply with the minimum requirement specified in the EDS and any standard referenced therein.
4.2 MDS and EDS numbering system
Each MDS and EDS number consists of a two-letter prefix followed by a three-digit sequential number and a
supplementary requirements suffix.
The first letter is fixed and consists of the letter "I" to indicate an IOGP MDS or EDS.
The second letter identifies the type of material or element with the following interpretation:
C − carbon steels
D − ferritic-austenitic stainless steels, type 22Cr duplex, type 25Cr duplex
H – hard facing, by welding, thermal spray, metal plating or use of sintered material
K − copper-nickel alloy 90-10 and other copper alloys including aluminium bronze
L − nickel-alloyed steel
M − martensitic stainless steel
N − nickel alloys

O − overlay welding, corrosion–resistant
R − austenitic stainless steels, type 6Mo
S − austenitic stainless steels, excluding type 6Mo
T − titanium and titanium alloys
U − precipitation-hardened stainless steels
V − Cr and Cr-Mo alloyed steels
X − high strength low alloyed steels
The suffix identifies a material delivered in accordance with the MDS including the supplementary
requirements for the following service:
S – sour service, excluding HIC testing
SH – sour service including HIC testing and UT examination, where applicable to the material and product
form
K – hydrogen service at elevated temperature and pressure
Material data sheets designated with supplementary suffix "S" or "SH" also satisfy all the MDS requirements
for general, non-sour service.
EXAMPLE 1 MDS IC003 designates carbon steel fittings for general, non-sour service, as opposed to
IC003S which designates carbon steel fittings which also comply with the additional supplementary
requirements for sour service, excluding HIC testing.
EXAMPLE 2 MDS IC003SH designates carbon steel fittings complying with the additional supplementary
requirements for sour service plus HIC and UT testing, where applicable.
4.3 Implementation of statutory regulations
This specification is not intended to address any statutory regulations. The responsibility for complying with
any such statutory regulations and the specification of any further additional requirements is the responsibility
of the end (equipment) user.
4.4 Ferritic-austenitic stainless steels (MDS ID series)
The compositional and microstructural requirements including ferrite content and acceptance criteria for
intermetallic phases and precipitates in parent material and welds are specified in accordance with ISO 17781.
Compliance with ISO 17781 is considered to fulfil the microstructural requirements of ISO 15156-3 /NACE
MR0175-3.
4.5 Mechanical testing
Tensile testing shall in general be carried out in accordance with the referenced standard specifications in the
respective MDS. Where testing to ASTM A370 is specified, testing in accordance with ISO 6892-1 is
considered equivalent and thereby also acceptable. The elongation shall be measured and reported in
accordance with the selected tensile test standard ASTM A370 or ISO 6892-1. For specimens to ASTM A370,
the gauge length shall be 50 mm as far as is practical.

Impact testing shall, in general, be carried out in accordance with the referenced standard specifications in the
respective MDS. Where testing to ASTM A370 is specified, testing in accordance with ISO 148-1 using a striker
radius of 8 mm is considered equivalent and thereby also acceptable.
The impact test temperature for carbon steels and duplex stainless steels is in general specified to be minus
46 °C. The use of a lower test temperature is acceptable, but the specified minimum absorbed energy shall
apply unless otherwise agreed with the end (equipment) user.
Hardness testing shall be performed in strict compliance with the methods described in the MDS and EDS, as
applicable. The use of alternative methods permitted by the product standard and use of conversion tables or
other correlations for individual materials shall require approval of the end (equipment) user. In case of dispute,
the hardness scale stated in the MDS or EDS shall govern. For the purposes of this specification, ASTM E384
is equivalent to ISO 6507-1, ASTM E18 is equivalent to ISO 6508-1 and ASTM E10 is equivalent to
ISO 6506-1. The use of portable hardness testing methods shall require approval by the end (equipment) user.
4.6 Machining of valve components from bar
When allowed by the product standard specifications, hollow cylindrically shaped parts, including valve bodies
for weld-end and integral flanged valves, and pressure-controlling parts of valves, may be manufactured from
cylindrically shaped bars, provided the requirements in the relevant MDS are met in full.
4.7 NDT of piping and valve components
4.7.1 General
Where MDSs specify NDT requirements, this is intended to represent the minimum level of NDT that shall be
performed at the material manufacturing stage.
NDT of fabricated piping systems are not included in the MDSs and additional NDT may be required for valve
components when a quality specification level (QSL) is specified by the purchaser in the valve data sheet or
purchase order documentation. For details of any additional NDT requirements for finished valve components
or piping assembly, reference shall be made to the applicable IOGP valve specification or piping fabrication
specification.
Where MDSs do not specify additional NDT requirements, the relevant material standard shall apply with no
additional requirements except as specified below in this section.
Where a frequency of inspection less than 100 % is specified, at least one item per lot shall be examined. If
defects outside the acceptance criteria are detected, two or more items from the same lot shall be tested and
if any of these two fails, all items in the lot shall be examined.
4.7.2 NDT Personnel
NDT personnel shall be qualified in accordance with ISO 9712 or ASNT SNT-TC-1A. Personnel performing
NDT evaluation shall be certified according to Level 2. Certification shall be performed by an independent third-
party certification body, or authorized qualifying body in accordance with ISO 9712 or the ASNT Central
Certification Program (ACCP).
4.8 Pilot castings
4.8.1 General
The casting foundry or manufacturer shall produce a pilot casting (see definition in 3.1.12) prior to the
production of castings, in accordance with MSS SP-147.
The pilot casting may be taken from the first production order of castings, subject to purchaser approval.
Acceptance of a production casting as pilot casting shall require that NDT complies with the requirements for
pilot casting and all testing specified in the MDS for production casting shall be met.

required on applicable design drawing.
Welding consumable
The welding consumable for the weld overlay shall comply with UNS N06625.
Welders, operators qualification
The welder or welding operators shall be qualified to ASME BPVC IX, ISO 9606 or ISO 14732.
Procedure General
qualification testing The welding procedures shall be qualified in accordance with ASME BPVC IX or ISO 15614-7, modified as
follows. The weld qualification test shall be carried out on base material of same grade as to be used in
production.
Qualification testing shall be carried out according to ASME BPVC IX or ISO 15614-7 and the following
additional requirements.
Chemical composition
The weld overlay deposit shall comply with UNS N06625 with a maximum iron content of 10 % by mass
measured at the minimum qualified thickness, unless a lower value of 5 % iron by mass is specified by the
purchaser.
Hardness testing
Hardness testing shall be carried out on base material, heat affected zone and weld metal. Vickers hardness
HV5 or HV10 shall be used. The examination of the HAZ shall be carried out with maximum 0.5 mm (0.02 in)
distance between the indentations from fusion line, through HAZ into the unaffected base material.
Testing of HAZ shall be carried out with maximum 0.5 mm (0.02 in) distance between the indentations from
fusion line, through HAZ into unaffected base material. The hardness for HAZ and unaffected base material
shall not exceed 350 HV.
When sour service is specified by the purchaser, the hardness of the weld overlay, HAZ and unaffected base
material shall not exceed the maximum values specified in ISO 15156 /NACE MR0175 or
ISO 17945 /NACE MR0103. The hardness of finished machined overlay surface shall not exceed 35 HRC for
Alloy 625.
Heat treatment Heat treatment after overlay welding shall be carried out, as necessary, to meet specified properties

testing VT shall be carried out on each 100 % of the weld overlay according to ASME BPVC Sec. V, Article 9 or
ISO 17637. The testing shall be performed after machining, if applicable, and non-machined surfaces shall be
cleaned prior to the testing. Porosity, slag inclusions are not permitted on and within 50 mm (2 in) of sealing
surfaces.
All deposited surfaces shall, after final machining, be penetrant tested in accordance with ASME BPVC V,
Article 6 with acceptance criteria according to ASME BPVC VIII, Div. 1, Appendix 8, except on sealing
surfaces where no indication is acceptable.
Thickness of weld overlay
The weld overlay thickness shall be measured at minimum three locations for each component. For
components with complicated geometry the manufacturer shall establish a procedure for this purpose.
