Notes:1. Nothing in this specification should be interpreted as indicating a preference by the committee for any material orprocess or as indicating equality between the various materialsor processes. In the selection of materials and processes, thepurchaser has to be guided by experience and by the service forwhich the pipe is intended.
2. Users of this specification should note that there is no longera requirement for marking a product with the API Monogram.The American Petroleum Institute continues to license use of themonogram on products covered by this specification, but it isadministered by the staff of the Institute separately from thespecification. The policy describing use of the monogram is contained in Appendix I. No other use of the monogram is permitted. Licensees mark products in accordance withAppendix I or Section 10, and nonlicensees mark products in accordance with Section 10.
A.1GeneralThis annex provides guidelines for enquiry and purchase of well-head and christmas tree equipment. These guidelines consist ofdata sheets to be completed by the purchaser, a series of typicalwellhead and christmas tree configurations, and a decision treefor determining product specification levels.
The data sheets are designed to perform two functions:
a) assist the purchaser in deciding what he wants;
b) assist the purchaser in communicating his particular needsand requirements, as well as information on the well environ-ment, to the manufacturer for his use in designing and pro-ducing equipment.
To use this Annex A, a copy of the data sheets should be com-pleted as accurately as possible. The typical configurationsshould be referred to, as needed, to select the required equip-ment. The decision tree Figure A.3, together with its instructions,provides the recommended practice as to which PSL each pieceof equipment should be manufactured. A copy of the data sheetshould then be attached to the purchase order or request for pro-posal.
A.2Data SheetsThe following pages contain questions and information that canbe used to select wellhead equipment, including chokes andactuators. Table A.2 contains general information which pertainsto the entire well. Tables A.3 to A.12 are designed to be used foreach type of equipment.
The effects of external loads (i.e. bending moments, tensions,etc.) on the assembly of components are not explicitly addressedby this International Standard (see 4.2.1.3). The purchasershould specify any exceptional loading configuration.
The purchaser should specify whether the performance verifica-tion procedures in Annex F are applicable.
A.3Typical Wellhead and Christmas TreeConfigurationsExamples of typical wellhead and christmas tree configurationsare shown in Figures A.1 and A.2. Also included are examples ofcasing and bit programmes that are consistent with the well-heads as shown.
A.4Product Specification Levels (PSL)A.4.1GeneralPSL 1 includes practices currently being implemented by a broadspectrum of the industry for service conditions recommended inthis Annex A.
PSL 2 includes all the requirements of PSL 1 plus additionalpractices currently being implemented by a broad spectrum ofthe industry for a specific range of service conditions asdescribed in this Annex A.
PSL 3 includes all the requirements of PSL 2 plus additionalpractices currently being implemented by a broad spectrum ofthe industry for a specific range of service conditions asdescribed in this Annex A.
PSL 3G includes all the requirements of PSL 3 plus additionalpractices currently being implemented by a broad spectrum ofthe industry for a specific range of service conditions asdescribed in this Annex A. The designation PSL 3G is only utilizedin those clauses and tables where necessary to define the addi-tional gas-testing requirements of equipment that can be gas-tested.
PSL 4 includes all the requirements of PSL 3G plus certain addi-tional requirements and is intended for applications that exceedthe service conditions usually identified within the scope of thisInternational Standard, and is normally only used for primaryequipment.
Figure A.3 shows the recommended specification level for pri-mary equipment. Primary equipment of a wellhead assemblyincludes as a minimum:
tubing head;
tubing hanger;
tubing head adapter;
lower master valve.
All other wellhead parts are classified as secondary. The specifi-cation level for secondary equipment may be the same as or lessthan the level for primary equipment.
The selection of PSL should be based on a quantitative riskanalysis which is a formal and systematic approach to identifyingpotentially hazardous events, and estimating the likelihood andconsequences to people, environment and resources, of acci-dents developing from these events.
The following comments apply to the basic questions asked inFigure A.3.

Annex A (informative)Purchasing Guidelines
A.4.2NACE MR 0175This applies if the partial pressure of hydrogen sulfide (H2S) inthe produced fluid equals or exceeds the minimum amount spec-ified by NACE MR 0175 for sour service.
A.4.3High H2S ConcentrationUse Yes if the H2S concentration of the produced fluid is suchthat in air an H2S concentration of 70 x 106 [70 parts per mil-lion (ppm)] can develop in case of a leak (human sense of smellcannot detect concentrations higher than 70 x 106).
Alternatively use Yes if the radius of exposure (ROE) to 100ppm H2S is greater than 15 m (50 ft) from the wellhead. ROE isdefined in Texas Railroad Commission Rule 36, see A.4.5. Othermethods of calculating ROE may apply depending on local regula-tions.
The above requires the knowledge of the adjusted open-flowrateof offset wells. If this is not available, but if hydrogen sulfide canbe expected, a 100 ppm ROE equal to 1,000 m (3,000 ft) may beassumed.
A.4.4Close ProximityUsers who are accustomed to the use of the close-proximity andradius-of-exposure concepts may substitute close proximity forgas well in Figure A.3.
The proximity assessment should consider the potential impactof an uncontrolled emission of H2S threatening life and environ-ment near the wellhead. The following list of items can be usedfor determining potential risk:
a) 100 ppm ROE of H2S is greater than 15 m (50 ft) from thewellhead and includes any part of a public area except a pub-lic road. ROE is defined in A.4.5. Public area means adwelling, place of business, place of worship, school, hospital,school bus stop, government building, a public road, all or anyportion of a park, city, town, village, or other similar area thatone can expect to be populated. Public road means any streetor road owned or maintained for public access or use;
b) 500 ppm ROE of H2S is greater than 15 m (50 ft) from thewellhead and includes any part of a public area including apublic road;
c) well is located in any environmentally sensitive area such as apark, wildlife preserve, city limits, etc.;
d) well is located within 46 m (150 ft) of an open flame or firedequipment;
e) well is located within 15 m (50 ft) of a public road;
f) well is located in or near inland navigable waters;
g) well is located in or near surface domestic water supplies;
h) well is located within 107 m (350 ft) of any dwelling.
These conditions are recommended minimum considerations.Any local regulatory requirements should be met.
A.4.5Radius of Exposure (ROE) of H2SA.4.5.1The following information is taken from Texas RailroadCommission Rule 36. SI metric-equivalent rules are not given, asthe method of ROE determination is used in the United Statesonly. Other methods of calculating ROE may apply depending onlocal regulations.
A.4.5.2For determining the location of the 100 ppm ROE:
X = [(1,589)(mole fraction H2S)(q)]0,625 8
For determining the location of the 500 ppm ROE:
X = [(0,454 6)(mole fraction H2S)(q)]0,625 8
where
X is the radius of exposure, in feet;
q is the maximum volume flowrate determined to be avail-able for escape, in cubic feet per day;
H2S is the mole fraction of hydrogen sulfide in the gaseousmixture available for escape.
A.4.5.3The volume flowrate used as the escape rate in determining theradius of exposure shall be that specified below, as applicable.
a) For new wells in developed areas, the escape rate shall bedetermined by using the current-adjusted open flowrate of off-set wells, or the field-average current-adjusted open flowrate,whichever is larger.
b) The escape rate used in determining the radius of exposureshall be corrected to standard conditions of 14.65 psia and60F (16C).
A.5Corrosivity of Retained FluidTo select the desired material class in Table 3, the purchasershould determine the corrosivity of the retained, produced orinjected fluid by considering the various environmental factorsand production variables listed in Table A.2. General corrosion,stress-corrosion cracking (SCC), erosion-corrosion, and sulfidestress cracking (SSC) are all influenced by the interaction of theenvironmental factors and the production variables. Other factorsand variables not listed in Table A.2 may also influence fluid cor-rosivity.
The purchaser should determine if materials shall meet NACEMR 0175 for sour service. NACE MR 0175 is only concerned withthe metallic material requirements to prevent sulfide stresscracking and not with resistance to general corrosion.Consideration should also be given to the carbon dioxide partialpressure, which generally relates to corrosivity in wells as shownin Table A.1. This table is a guideline only.
Analysis of produced fluids may not predict the field performanceof metallic or non-metallic material.

See following pages for Wellhead Equipment Data Sheets.
The minimum partial pressure of carbon dioxide required to initi-ate corrosion and the relative effect of increasing partial pres-sures on the corrosion rate are strongly influenced by other envi-ronmental factors and production variables, such as:
a) temperature;
b) H2S level;
c) pH;
d) chloride ion concentration;
e) sand production;
f) water production and composition;
g) types and relative amounts of produced hydrocarbons.
Finally, the purchaser should consider future service of the wellwhen selecting a material class. This should not be limited toanticipated changes in the acid gas partial pressures for produc-tion or increased water production with or without increasedchloride content, but also should include consideration of opera-tions such as acidification or other well treatments.

Impact testing shall be performed in accordance with therequirements of 6.3 of this Specification and ASTM A370. Exceptfor manual tong hinge pins of wrought material, the minimumaverage Charpy impact energy of three full size test pieces shallbe 20 ft-lb (27 J) with no individual value less than 15 ft-lb (20 J).For manual tong hinge pins of wrought material, the minimumaverage impact energy of three full size Charpy impact testpieces shall be 11 ft-lb (15 J) with no individual value less than8.5 ft-lb (12 J).
Each primary load bearing component shall be marked SR2 toindicate that low temperature testing has been performed. Eachprimary load bearing component shall also be marked with thetemperature in degrees Celsius to indicate the actual design andtest temperature.
B.3SR2AAdditional Low Temperature TestingUnder this supplementary requirement, impact testing shall alsobe applicable to materials used in the primary load carryingcomponents of equipment normally exempted from impacttesting. The components to which impact testing shall apply shallbe determined by mutual agreement of the purchaser and themanufacturer.
Impact testing shall be performed in accordance with therequirements of 6.3 of this Specification and ASTM A370. Themaximum impact test temperature and the minimum averageand individual values shall be as agreed upon by the purchaserand the manufacturer.
Each covered primary load carrying component shall be markedSR2A to indicate that additional low temperature testing hasbeen performed. The component shall also be marked with thetemperature in degrees Celsius to indicate the actual design andtest temperature.
B.4SR3Data BookWhen requested by the purchaser, records shall be prepared,gathered, and properly collated in a data book by the manufacturer.
The data book shall at least include for each unit:
Statement of Compliance
Equipment Designation/Serial Number
Assembly and Critical Area Drawings
Nominal Capacities and Ratings
