9 5/8" 47# P110 HC JFE Bear R3 Surplus Casing (5,782 Feet)The position window is principally determined from finite element analysis.DESCRIPTION OF THE INVENTION General Description of the Method A tubular joint embodying the present invention is shown in detail in FIG. 1 will be discussed in detail below.The smaller the pipe diameter, and the higher the grade, the more difficult it is to obtain a seal.
By contrast, the other pipe section 10B in coupling 18 is improperly connected to its box member 20B, in that the face 22 B is not at least aligned with triangle base 26 B, leaving triangle 17 completely exposed.Such pin members are threaded into couplings, collars or integral female pipe sections called box members.If the connection successfully sealed to this point, the process was repeated with up to 10 degrees per 100 feet of bending.
Coupling and Thread Dimensions for API-Casing Buttress ThreadBy creating a positive shouldered makeup identical to a premium connection, API certified pipe can be run, rotated,.Detail Specification of the Casing 5.5 Body OD, 15.5 ppf, K-55 5.8.API 5CT Coupling for Tubing, API 5CT Coupling for Casings, API 5L Linepipe Coupling.
Field of the Invention This invention relates to the field of tubular connections and methods for connecting tubular members, particularly for oilfield connections of threaded buttress pin and box members. 2. Background Description Pipe sections used in oil fields (for example long sections of well casing) usually have a tapered, exteriorly-threaded male end called a pin member.Although these two torque operations require different torque values, the triangle marks remain identical because the needed threaded axial engagement remains the same.Dear All, Please help me to calculate or show any helpful tips or reference on above subject.The test results from tin plated couplings lubricated with API modified thread lubricant revealed that this makeup condition will not reliably seal gas internal pressure for this size, weight, and grade combination.
Directional casing while drilling applied to improve highHi All, I would like to know how the make-up torque for a buttress connection is calculated.

It should be noted that API does not specify makeup torques for API BTC.The reverse angle torque shoulder provides a positive torque stop, which allows for accurate power tight make-up and minimizes hoop stresses in the connection.
Hunting Energy Services | TKC Convertible BTCThis torque is sometimes determined by API torque recommendations.
Experience has shown that these relatively low reference torques result in significant variations, even on virtually identical connection specimens.
PERFORMANCE PROPERTIES Requirements for Leak Resistance ofAside from these differences, the testing program was the same for all sizes.

Additional tests were conducted at a later date that were made-up to the apex of the triangle.Make Up Torque LTC Trpon Pipe - Free download as PDF File (.pdf), Text File (.txt) or read online for free.Therefore, the thread torque values can be prescribed for specific torque operation.For 80 ksi and lower grade materials, tin plated couplings with API modified thread lubricant successfully sealed gas internal pressure 100% of the time.Our state of the art casing plant was built in 2005 and has a capacity of 80,000 metric tons per year.
SUBJECT: COUPLING MAKE-UP - Hunting EnergyAt the low end of the tolerance, the tin plating thickness will completely fill the thread root to crest clearance and most of the thread flank clearance, greatly minimizing the area that the thread lubricant must bridge off to effect a seal.Torque measuring equipment. commonly used on API LTC and API BTC casing may also be.
Free Download Here - pdfsdocuments2.comThe first pipe section 10A is provided with a triangle mark 16 at a predetermined position on the exterior surface of the section 10A, in accordance with API Std. 5B. A second pipe section or coupling 18 with length N L includes two corresponding threaded box members 20A and 20B having respective faces 22A and 22B at their ends, as shown in FIG. 1. The internal threads are plated with tin 11A.BEST MODE The sealing capability of the API buttress connection is dependent on the thread lubricant that is trapped in the thread area.
In addition to casing coupling, we also offer pup joint, EUE API.It is well known in the petroleum industry that the performance of an API connection is highly dependent on the makeup assembly (engagement) condition of the joint, and therefore it is important to determine if the joint is made-up properly.
