Those found damaged should be laid aside unless satisfactory means are available for correcting thread damage. Casing handling equipment and slips should be checked for proper size and examined to see that all segments lower together. Identify all crossover joints and the first joint of each weight. Verify each pipe joint as to weight. Both floor and elevator slips should be clean. 3.2. remove thread protectors from both field and coupling ends and clean the threads thoroughly. The actual length under tension will be greater due to stretch of the pipe under load. Number and tally each joint of casing as it is loaded on the rack. number each joint as it goes in the hole (1. If the pipe tally is made with “threads on” (full length of pipe) then the running footage can be calculated using adjustment factors found in Appendix. If they lower unevenly there is danger of denting or slip-cutting the pipe. have proper dies and should fit properly. Slip-type elevators are recommended. Page 43 MLT™ Ring Field Make-Up Handbook .) The total of the individual lengths so measured will represent the unloaded length of the pipe string. 5. Care should be taken to ensure the floor slip is level. Immediately before running casing. tighten the coupling before pulling the pipe into the derrick. It is recommended that a thread compound that meets the performance objectives of API Bulletin 5A2 be used. Check each coupling for make-up.) 10. Care should be taken to ensure the drift mandrels conform to the requirements of API 5CT by measuring the drift’s length and diameter before each job. Torque values for some widely used compounds with Teflon particles will usually be approximately 10% less.

Page 48 MLT™ Ring Field Make-Up Handbook . 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. This does not indicate that the coupling on the mill end is too loose but simply that the field end has reached the tightness with which the coupling was screwed on at the manufacturer’s facility. In making up the field joint. fill casing as it is being run. it is possible for the coupling to make up slightly on the mill end. When this is done. Joints that are questionable as to their proper tightness should be unscrewed and the casing laid down for inspection and repair. k.

Floating the casing in is a poor practice and should be avoided. Excess slack-off will buckle the string and damage the connections. l. the casing should be laid down for inspection. If wobbling should persist despite reduced rotational speed. Serious consideration should be given before using such casing in a position in the string where heavy tensile load is imposed. h. i. stop and check to ensure they are operating. Tag bottom carefully. 73.

Red and blue rings will dominate usage. • Apply back-up jaws to the mill end pipe body during make-up. make-up speed at the point the pin contacts the ring should not exceed 15 RPM. • Refer to the torque tables and select the appropriate maximum torque for the casing or tubing and the ring being used. • Ensure the MLT™ Ring is installed properly and is seated in the center of the coupling against the mill end pin. RECOMMENDED Field Make-up Practices API Threads with MLT™ Rings The following recommended practices are for use with MLT™ Rings and are in addition to the recommended practices described in the previous Section II. For proper ring installation procedures. • Continue to make up the remainder of the string. Page 52 MLT™ Ring Field Make-Up Handbook . • Apply a thin even coat of thread compound to the coupling and pin threads. Care should also be taken to follow the preparation and running procedures in Section II. Running Procedure • Remove protectors and visually inspect the pin and coupling threads.e. on the tong to relieve at the specified make-up torque. • Record the torque just prior to the pin shouldering on the ring. the torque will increase sharply. or dump valve. • If necessary. At the shoulder point. • Make-up the first connection to the target torque as specified. • Ensure “Acceptance Criteria” are met (see following table). contact TESCO. Ring installation is easily performed with a hydraulic installation tool. adjust the tong torque setting so as not to exceed the delta torque but ensuring the pin shoulders on the ring. Threads should be clean and free of defects. • Set the pressure relief valve. lay down pin joint. 5) If shoulder torque is still less than minimum acceptable value after the second make-up.

This also indicates an unfavorable geometry. lay down joint and re-use the coupling and ring. change out the coupling and install a new MLT™ Ring. In the unlikely event that the shoulder torque is below MINIMUM acceptable noted in the acceptance criteria above. FIELD Ring Installation (Floating rings without install kit) For tubing only. the rings can be installed by letting the connection make-up press the ring into place with the following procedure. Thread the coupling on the mill end hand tight. Page 56 MLT™ Ring Field Make-Up Handbook . Float the connection make-up not exceeding 10 RPM during make-up. If the shoulder torque is again below the MINIMUM then the joint should be set aside. Install a RED MLT™ Ring in the coupling by hand with the color facing up. install a GREEN MLT™ Ring and re-make.CRITERIA f. remove the coupling. if an installation kit is not readily available. If tongs are used to break-out connections. the backup tong should be placed on the coupling to help preclude deforming the pipe. d. 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. For breaking out connections on the field end on rig floor. and preclude backing off the connection on the mill side. Breaking Out Connections If it is necessary to break out connections. a. Connection break-out torque typically is 10 % to 30 % higher than make-up torque. After connections are broken out. b.IV. Higher break-out 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. the grips should be positioned close to the coupling. 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. Tong grips should be clean and have proper dies. Any metal whiskers found should be removed and galled spots should be carefully repaired. e. both pin and coupling threads should be cleaned and inspected for thread damage. Page 57 MLT™ Ring Field Make-Up Handbook . the following procedures are recommended. c. particularly important for lighter wall thickness pipe.
