· The buttress thread form refers to two different thread profiles. One is a type of leadscrew often used in machinery, and is also known as the sawtooth thread or breech-lock thread form. The asymmetric thread form allows the thread to have low friction and withstand greater loads than other forms in one direction, but at the cost of higher friction and inferior load bearing in the opposite.
The make-up torque is an important variable to be considered in the modeling of tapered threaded connections, once the torque had great influence in the jump-out results. Besides, the standard API Buttress has higher resistance to jump-out than the API Short Round. vinciconoralb.it collapse grades have the same yield torque values as the corresponding minimum yield strength. vinciconoralb.it-up torques will vary but shall not exceed 90% of connection yield torque. vinciconoralb.itnce USS-CDC HTQ™ Recommended Practices for running procedures.
vinciconoralb.it = Specified Minimum Yield Strength. SIZE EUE STC LTC BTC *DELTA TORQUE is the torque boost added to the normal make-up torque, referred to as “shoulder torque”.
Higher torques may be available with higher strength MLT Rings. INSTALLATION OF MLT RING IS FAST AND EASY. · Make-up torque calculation procedures are presented for API-type round thread casing connections with non-API weights, grades, and coupling dimensions.
These are connections which are commonly used in the industry, but for which there is not an industry-published reference on make-up procedures. Included are a simplified version of the API.

Volant’s DTR ® and Multi-Lobe torque rings have been engineered to provide additional torque capacity for casing and tubing connections for the upstream market.
They are designed to fit standard API casing and tubing connections, providing a cost-effective, enhanced connection solution with a short-lead time. Bushmaster™ SP was designed to be the next generation’s semi-premium connection.
It provides a solution to the issues plaguing API BTC compatible connections: limited torque, inconsistent makeup profiles, spinning couplings, poor sealability, and high connection stress. The Constrictor™ thread form is tight fitting, providing an outstanding thread seal, reduces hoop stress to half that.
The procedures set forth are referred to as "torque-position" because the make-up torque and final position are used as acceptance criteria for the assembly operation. The connections are threaded in accordance with API 5B. The torque-position assembly parameters have been developed for most SC (short round thread casing), LC (long round thread Author: API. Premiere Torque Rings are an innovative, patented technology that provides premium connection performance at a significantly lower cost.
By creating a positi. Pin Abutment results in high resistance to over-torque, more than 3 times as high as API Buttress. Pin abutment results in high resistance to compression; Gas-tight seal under compression; Mill end is made up further than field end to avoid mill end rotation when make up field end; Precise make-up position control reduces hoop stress on the.
