INTRODUCTION TO TORQUE TABLES API Round Thread API Buttress Thread Tesco MLT Rings These Torque Tables and Recommended Practices provide performance ratings and field practices for power tight assembly of new API Round and Buttress threads. The torque values in the tables for Round thread casing and tubing without MLT Rings are in accordance with API Recommended Practice 5C1. The torque values in the tables for Tesco MLT Rings are in accordance with Tesco recommended practices when used with new API tubing and casing connections. Previously made-up threads, particularly tubing, may demonstrate reduced torques due to permanent deformation of pin and/or coupling. Torque values and friction coefficients are affected by a large number of variables, such as variations in taper, lead, thread height and thread forms, surface finish, type of thread compound, length of thread, coatings and weight and grade of pipe. The torque values represented in the tables are for API Modified thread compound. Use of other compounds may result in different torques. The API Round thread torque values (referred to as shoulder torques) included in the tables herein apply to connections with zinc-plated or phosphatecoated couplings. For API Round thread connections with other coupling coatings or platings, couplings with the modified feature (seal rings), or using thread compounds other than API Modified, the Round thread (shoulder) torques in the tables herein should be adjusted by multiplying torques by the following factors: Factor Tin plated couplings: 0.80 Couplings with PTFE (Teflon) rings 0.70 Note: All round thread reflected in the text and following tables are 8 threads per inch, commonly referred to as 8-Round.

For API Round thread connections the recommended practice for power tight assembly includes using the API specified make-up torque as the primary criteria.260 ft-lbs.PMD Page 5 4/21/2004. (Note estimates of the make-up shoulder torques for Buttress are referenced in the table.000 ft-lbs for this connection) API Round and Buttress Thread with MLT Rings The MLT Ring provides a significant boost in torque capacity to Round and Buttress thread connections. Example: 7" 23# K-55 LTC The torque for power tight make-up should fall between the minimum and maximum torques of 2.560 ft-lbs and 4. For API Buttress thread connections the recommended practice for power tight assembly includes using the position of the pin in the coupling as the primary criteria for make-up.. Example: 7" 23# K-55 BTC The pin should be made up in the coupling until the end of the coupling reaches the base of the triangle stamped on the pin end.e. then using the observed torque for that position as an aid to run the casing. i. The total torque capacity is determined as follows: TorqueTotal = TorqueShoulder + TorqueDelta Where. TorqueShoulder = Torque to bring pin end into contact with the MLT Ring MLT Ring Field Make-Up Handbook ML Torque Ring Field Make-Up Handbook 11 col 5 April 16. After making up several connections in this manner the observed torque should then be used to make up the rest of the string.HOW TO USE THESE TABLES Please refer to the recommended practices that accompany these tables. 10:01 AM ..

They can be estimated with the tables herein using as the shoulder torque the API Recommended Torques for Round thread or the tabulated estimated make-up torque shown for Buttress threads. Example: 7" 23# N-80 LTC For Shoulder Torque = API Minimum Torque Torque Shoulder = 3. The Delta Torques in the table are for L-80 grade rings. Texas 77041 713-849-5900 Email:

Where the shoulder torque is higher then total torque will also be higher. Values for TorqueTotal are provided in the tables.820 ft-lbs TECHNICAL SERVICES NOTE: Higher torque performance using the MLT Ring may be available depending on the casing or tubing and the operator design requirements. 10:01 AM . For Round thread the shoulder torque is conservatively assumed to be the Minimum API recommended torque. Total Torques.320 + 4.320 ft-lbs from the LONG thread Table (minimum) Torque Delta = 4.720 ft-lbs For Shoulder Torque = API Optimum Torque Torque Shoulder = 4.400 ft-lbs from the LONG Table Torque Total = 4.400 ft-lbs from the LONG Table Torque Total = 3. 4. In some cases the ring ID is less than the pipe ID and for these cases the ring ID is highlighted in yellow. Delta torque is the torque boost provided by the MLTTM Ring and is added to the shoulder torque to provide the total torque. 6. Ring ID is prior to forming lobes. the Delta torque is conservatively limited by the elastic limit of the ring or pin in compression. Torque Total is provided as a range of Min and Max for Round thread depending on the actual shoulder torque observed in the field.

It is recommended to break circulation slowly just prior to tagging bottom and before any pipe reciprocating is carried out. The base of the triangle will aid in locating the thread vanish point for basic power-tight makeup. the mating coupling should be carefully inspected for damaged threads. 10:01 AM . Casing wobble indicates the thread may not be in line with the axis of the casing and is usually minimized when using a top drive. it is possible for the coupling to make up slightly on the mill end. Serious consideration should be given before using such casing in a position in the string where heavy tensile load is imposed. Tag bottom carefully. If casing has a tendency to wobble unduly at its upper end when making up with a tong the speed of rotation should be decreased to prevent galling of threads. Parted joints should never be reused without a shop check or regauging. Excess slack off will buckle the string and damage the connections. h. API 5B) g.

Otherwise. lay down joints. install a new MLT Ring and remake with proper delta toque and re-drift. b) If both pin and coupling drift. 4) After breakout.CRITERIA CORRECTIVE ACTION if criterion not met: 3. If connection drifts and is at position. proceed to step four. 2) If the connection is made up to position. This rare occurrence indicates undesirable geometry and will compromise torsion capacity. 10:02 AM . (See ring installation section).

(Last thread not visible on field end) AND Connection rotation must not exceed 1/8 turn after shouldering (avoids forcing the ring to encroach on the drift diameter). drift the coupling and pin ends. If undamaged. break out connection and inspect for visual damage. a) If the drift requirement is not met in one or both components. PMD Page 37 4/21/2004.

(See Field ring installation Par. 10:02 AM . This also indicates an unfavorable geometry. lay down joint and re-use the coupling and ring. Thread the coupling on the mill end hand tight.PMD MLT Ring Field Make-Up Handbook 4/21/2004. FIELD Ring Installation (Floating rings without install kit) For tubing only. if an installation kit is not readily available.CRITERIA f. Float the connection make-up not exceeding 10 RPM during make-up. remove the coupling. In the unlikely event that the shoulder torque is below MINIMUM acceptable noted in the acceptance criteria above. If the shoulder torque is again below the MINIMUM then the joint should be set aside. the rings can be installed by letting the connection make-up press the ring into place with the following procedure. Page 38 ML Torque Ring Field Make-Up Handbook 11 col 38April 16. Install a RED MLT Ring in the coupling by hand with the color facing up. 10:02 AM . install a GREEN MLT Ring and re-make. Connection breakout torque typically is 10 % to 30 % higher than make-up torque. c. Breaking Out Connections If it is necessary to break out connections the following procedures are recommended.IV. Slips can be used for backup as long as the weight on string is adequate and the pipe does not turn in the slips cutting the pipe. e. d. b. Tong grips should be clean and have proper dies. MLT Ring Field Make-Up Handbook ML Torque Ring Field Make-Up Handbook 11 col 39April 16.If tongs are used to break out connections. particularly important for lighter wall thickness pipe. the backup tong should be placed on the coupling to help preclude deforming the pipe. It is preferred to apply back out torque with the top drive or power tongs as these will distribute the applied forces better than rig tongs. 10:02 AM . both pin and coupling threads should be cleaned and inspected for thread damage.After connections are broken out. a.For breaking out connections on the field end on rig floor. and preclude backing off the connection on the mill side.If the pipe is not breaking out easily it is acceptable to use the manual tongs and recommended they be used in combination with the top drive or power tongs. the grips should be positioned close to the coupling.PMD Page 39 4/21/2004. Higher breakout torque up to double the make-up torque can be influenced by factors such as use of compounds with Teflon and / or drill string vibration encountered during casing drilling. Any metal whiskers found should be removed and galled spots should be carefully repaired. Tubing. MLTTM Ring Multi-Lobe Torque Ring. Gauging.PMD MLT Ring Field Make-Up Handbook 4/21/2004.
