ISO 13678 2009 E, ISO the International Organization for Standardization is a worldwide federation of national standards bodies.
ISO member bodies The work of preparing International Standards is normally carried out through ISO. technical committees Each member body interested in a subject for which a technical committee has been. established has the right to be represented on that committee International organizations governmental and. non governmental in liaison with ISO also take part in the work ISO collaborates closely with the. International Electrotechnical Commission IEC on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO IEC Directives Part 2. The main task of technical committees is to prepare International Standards Draft International Standards. adopted by the technical committees are circulated to the member bodies for voting Publication as an. International Standard requires approval by at least 75 of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent. rights ISO shall not be held responsible for identifying any or all such patent rights. ISO 13678 was prepared by Technical Committee ISO TC 67 Materials equipment and offshore structures. for petroleum petrochemical and natural gas industries Subcommittee SC 5 Casing tubing and drill pipe. This second edition cancels and replaces the first edition ISO 13678 2000 which has been technically. It is the intent of ISO TC 67 that the first and second editions of ISO 13678 both be applicable at the option of. the purchaser for a period of six months from the first day of the calendar quarter immediately following the. date of publication of this second edition after which period the first edition will no longer be applicable.

ISO 13678 2009 E,Introduction, This International Standard is based on API RP 5A3 5 second edition July 2003 with errata and inclusion of. all clauses of API RP 7A11 6 first edition November 1992 incorporated into Annex I. This International Standard specifies requirements and gives recommendations for the manufacture testing. and selection of thread compounds for use on casing tubing line pipe and drill stem elements based on the. current industry consensus of good engineering practice. It is intended that the words casing and tubing apply to the service application rather than to the diameter of. The performance requirements of thread compounds for use with casing tubing line pipe premium. connections and rotary shouldered connections include. consistent frictional properties that allow both proper and uniform connection engagement. adequate lubrication properties to resist galling or damage of connection contact surfaces during make up. and breakout, adequate sealing properties for thread type seal connections and or not inhibiting the sealing properties. of non thread sealing connections e g metal to metal seals polytetrafluoroethylene PTFE seals etc. depending upon service requirements, physical and chemical stability both in service and in expected compound storage conditions. properties that allow effective application to the connection contact surfaces in expected service. conditions and environment, In addition compounds for rotary shouldered connections provide.
lubrication of the connection members during make up to achieve the proper axial bearing stress. an effective seal between connection shoulders to prevent wash out by drilling fluids. more uniform distribution of circumferential bearing stress if shoulders are not parallel. resistance to additional make up down hole, When evaluating the suitability of a thread compound the user can define the service conditions and then. consider field trials and field service experience in addition to laboratory test results Appropriate. supplementary tests can be utilized for specific applications which are not evaluated by the tests herein The. user and manufacturer are encouraged to discuss service applications and limitations of the compound being. considered, Representatives of users and or other third party personnel are encouraged to monitor tests wherever. possible Interpolation and extrapolation of test results to other products even of similar chemical. composition is not recommended, 1 Obsolete Incorporated into this International Standard.

INTERNATIONAL STANDARD ISO 13678 2009 E, Petroleum and natural gas industries Evaluation and testing. of thread compounds for use with casing tubing line pipe and. drill stem elements, This International Standard provides requirements recommendations and methods for the testing of thread.
compounds intended for use on ISO API thread forms as well as proprietary casing tubing line pipe and drill. stem elements with rotary shouldered connections The tests outlined are used to evaluate the critical. performance properties and physical and chemical characteristics of thread compounds under laboratory. conditions, These test methods are primarily intended for thread compounds formulated with a lubricating base grease. and are not applicable to some materials used for lubricating and or sealing thread connections It is. recognized that many areas can have environmental requirements for products of this type This International. Standard does not include requirements for environmental compliance It is the responsibility of the end user. to investigate these requirements and to select use and dispose of the thread compounds and related waste. materials accordingly,2 Conformance,2 1 Dual citing of normative references. In the interests of world wide application of this International Standard Technical Committee ISO TC 67 has. decided after detailed technical analysis that certain of the normative documents listed in Clause 3 and. prepared by ISO TC 67 or another ISO Technical Committee are interchangeable in the context of the. relevant requirement with the relevant document prepared by the American Petroleum Institute API the. American Society for Testing and Materials ASTM and the American National Standards Institute ANSI. These latter documents are cited in the running text following the ISO reference and preceded by or for. example ISO XXXX or API YYYY Application of an alternative normative document cited in this manner will. lead to technical results different from the use of the preceding ISO reference However both results are. acceptable and these documents are thus considered interchangeable in practice. 2 2 Units of measurement, In this International Standard data are expressed in both the International System SI of units and the United. States Customary USC system of units For a specific order item it is intended that only one system of units. be used without combining data expressed in the other system. Products manufactured to specifications expressed in either of these unit systems shall be considered. equivalent and totally interchangeable Consequently compliance with the requirements of this International. Standard as expressed in one system provides compliance with requirements expressed in the other system. For data expressed in the SI system a comma is used as the decimal separator and a space as the. thousands separator For data expressed in the USC system a dot on the line is used as the decimal. separator and a space as the thousands separator In the text data in SI units are followed by data in USC. units in parentheses,ISO 2009 All rights reserved, Copyright International Organization for Standardization 1.

Provided by IHS under license with ISO, No reproduction or networking permitted without license from IHS Not for Resale. ISO 13678 2009 E, In the case of a thread compound the dropping point is considered to be an indicator of the thermal stability of. the base grease and other lubricant additives Poor thermal stability could adversely affect thread compound. performance in high temperature field service In order to meet present day requirements for high temperature. service the minimum dropping point temperature shall be 138 C 280 F as measured in accordance with. ISO 2176 or ASTM D2265, NOTE Extreme temperature field service conditions can require a higher performance limit. 5 2 3 Evaporation, The evaporation test indicates a thread compound s physical and chemical stability at elevated temperatures.
which is related to the base grease oil or other additives Due to the wide variation in mass density of thread. compounds currently in service percentage mass fraction does not provide a reliable basis for comparison. therefore evaporation loss shall be measured as a percentage volume fraction The evaporative loss when. evaluated in accordance with the test method in Annex D for a 24 h duration at a temperature of 100 C. 212 F shall not exceed 3 75 volume fraction,5 2 4 Gas evolution. The gas evolution test indicates a thread compound s chemical stability at elevated temperatures When. evaluated in accordance with the test method in Annex G the volume of gas evolution shall not exceed. 5 2 5 Oil separation, The oil separation test indicates a compound s physical and chemical stability at elevated temperatures which. is related to the base grease oil Due to the wide variation in mass density of thread compounds currently in. service percentage mass fraction does not provide a reliable basis for comparison therefore oil separation. loss shall be measured as a percentage volume fraction In order to meet current requirements for high. temperature service the maximum oil separation loss when evaluated in accordance with the test method in. Annex E shall be 10 0 volume fraction,5 2 6 Penetration. The penetration test measures the consistency i e thickness or stiffness of a lubricating grease and. relates to the ease of application or brushability of a thread compound The compound manufacturer shall. measure and record the penetration of each production batch of thread compound and report the mean value. for that specific compound When evaluated in accordance with the test method in Annex C the penetration. acceptability range minimum to maximum at 25 C 77 F shall not be greater than 30 cone penetration. points An acceptability range for penetrations is used because thread compounds with penetrations between. 265 and 385 can be used for different applications For information purposes cold temperature penetration at. 7 C 19 F is reported as a typical value Mass density affects the values obtained from this procedure. Therefore it is not a useful measurement for relative comparisons of materials with widely varying mass. NOTE Brookfield viscosity ASTM D2196 19 is not substantially affected by material mass density and therefore can. provide a closer correlation to brushability than the cone penetration The range below was determined using several. different supplier samples of API modified thread compound as well as proprietary thread compounds used currently with. casing tubing and line pipe connections It is appropriate that a specific spindle size rotational frequency and test. temperature be utilized to develop viscosity data for comparison The Brookfield viscosity range as measured with a 7. Spindle at 10 r min and 25 C was 200 000 mPa s to 400 000 mPa s A typical value for API modified thread compounds. could range from 200 000 mPa s to 240 000 mPa s,ISO 2009 All rights reserved. Copyright International Organization for Standardization 7. Provided by IHS under license with ISO, No reproduction or networking permitted without license from IHS Not for Resale.
ISO 13678 2009 E, The SI unit of viscosity is the pascal second Pa s The pascal second is rarely used in scientific and. technical publications today The most common unit of viscosity is the dyne second per square centimetre. dyne s cm2 which is given the name poise P after the French physiologist Jean Louis Poiseuille 1799. 1869 Ten poise equal one pascal second Pa s making the centipoise cP and millipascal second mPa s. 1 pascal second 10 poise 1 000 millipascal second,1 centipoise 1 millipascal second. 5 2 7 Mass density, The mass density test result of a thread compound depends on the type and quantity of the constituents. utilized in the formulation The range of mass density between production batches for a particular thread. compound is an indication of the consistency of manufacture The compound manufacturer shall measure and. record the mass density of each production batch of thread compound and report the mean value for that. specific compound The mass density of a particular thread compound batch shall not vary more than 5 0. from the manufacturer s established mean value,5 2 8 Water leaching. The water leaching test indicates the physical and chemical stability of compounds when exposed to water at. elevated temperatures When evaluated in accordance with the test method in Annex H the compound mass. loss shall not exceed 5 0,5 2 9 Application and adherence properties.
Thread compounds should be applied in a manner consistent with the compound manufacturer and thread. manufacturer s recommendations and in sufficient quantity to provide effective lubrication and or sealing. characteristics for threaded connections The thread compound shall be brushable and capable of adherence. over a temperature range of 7 C 19 F to 66 C 151 F without either agglomerating or sliding off the. Laboratory tests for determining the thread compound application and adherence properties shall be. performed and recorded The laboratory test methods described in Annex F are intended to provide a means. for comparing thread compound performance but it is possible for them not to be representative of field. 5 2 10 Corrosion inhibition and protection properties. Thread compounds are often utilized to provide shipping and storage corrosion protection on threaded. connections as well as lubrication and sealing properties Certain field exposure conditions particularly on. offshore platforms and in service conditions such as sour gas environments require corrosion protection and. inhibition Therefore the thread compounds with corrosion protection shall provide an effective barrier against. and not contribute to corrosive attack of connection threads and seals The corrosion inhibition properties of. thread compounds depend on application variables such as the following. compound additive types and treatment levels, type and condition of threading process fluids and residue remaining on thread surfaces. compound application method and equipment utilized. type of thread protector and application method knock on or screw on. specific user application procedures and environmental conditions. compatibility with thread storage compound, galvanic differences between compound components environment and connector material. Copyright International Organization for Standardization ISO 2009 All rights reserved. Provided by IHS under license with ISO, No reproduction or networking permitted without license from IHS Not for Resale. ISO 13678 2009 E, A laboratory test shall be performed and recorded to determine whether potentially corrosive components are. present in the thread compound A copper corrosion test should be carried out in accordance with the. procedures in ASTM D4048 or equivalent Although copper is not typically utilized other than as a thread. surface plating in production connections it more readily reacts in the presence of reactive materials such as. sulfur and chlorine which can also damage steel Thread compounds should provide a level 1B or better by. this method For RSCs if thread compounds with metallic zinc are used it is recommended that active sulfur. be limited to less than 0 3, A laboratory test for determining the thread compound corrosion inhibition properties should be performed and.
Thread compounds vary as to the existence and treatment level of corrosion inhibition It is therefore the. purchaser s user s responsibility to outline the necessary requirements with the compound manufacturer for. products being utilized for storage or corrosive field applications The methods listed in Annex L are generally. accepted and utilized by lubricant test laboratories and users They are intended to provide a means for the. relative comparison of thread compound properties,5 2 11 Compound stability properties. Thread compound stability both in storage and in service is a property essential to adequate sealing. performance within an assembled connection Instability in the form of excessive softening and separation can. result in the development of leak passages over time or with changes in temperature Excessive hardening in. storage can adversely affect brushability and proper application of the compound onto the pipe thread. The compound manufacturer shall keep production batch samples and evaluate them periodically for storage. stability Thread compound storage stability over a minimum of 12 months is adequate to resist softening or. hardening of more than 30 cone penetration points at 25 C 77 F when evaluated in accordance with the. test method in Annex C Stratification or oil separation should not be greater than 10 0 volume fraction over. a minimum period of 12 months The test described in Annex M should also be performed and is intended to. provide a means for the relative comparison of thread compound high temperature stability. Thread compound stability test results shall be available in a product bulletin. 6 Thread compound performance properties,6 1 Small scale test. The small scale bench top test described in I 4 compares the friction properties of a test compound to a. lead based reference compound formulated for laboratory use There is a possibility that small scale tests. might not correlate directly with full scale connection tests or be truly representative of field service Annex I. formerly API RP 7A1 6 obsolete covers a small scale test procedure that was developed and validated. utilizing the metal based RSC compounds that were commonly used in field applications in the early 1990s. Subsequent industry test programmes utilizing non metallic RSC compounds have shown limited correlation. of small scale test frictional properties with full scale test results Therefore this test method has limited. usefulness for determining friction factors for non metallic compounds for use on any type of connection. 6 2 Frictional properties, A thread compound acts as a lubricant during make up and breakout and provides consistent and repeatable. frictional properties between the mating members of a threaded connection For a given amount of connection. engagement a specific number of engaged threads the torque required varies in direct proportion to the. apparent coefficient of friction of the thread compound connection system The frictional properties of the. thread compound connection system affect the following torque values. the torque required to make up the connection, Copyright International Organization for Standardization ISO 2009 All rights reserved 9.
