TMC Group Managing Company LLC manufactures and supplies casing couplings.
Details
Casing couplings
Purpose
The couplings are intended to connect casing pipes used in construction of oil and gas wells and are manufactured as per GOST 632-80 with OTTM and OTTG threads, as well as BUTTRESS threads as per TU 14-ZR-29-2007. Premium class casing pipe couplings with patented thread TMC-OTV, TMC1-SRV, TMC1-SRV2 are used in complex-profile oil and gas wells, requiring enhanced performance, as well as for extraction of super-viscous oil by steam-assisted gravity drainage.Field of application
- High-strength, high-hermetic threaded joint TMC-OTV is used in oil and gas wells of complex profile, as well as wells where coolant is transported at temperatures up to 482 °F. The unique design consists in sealing of the threaded joint due to interference contact at the pin toroidal seal band with the tapered bore in the box.
- High-strength, high-hermetic threaded joint TMC1-SRV provides high make-up torque (up to 20.283 lbsf-ft), maintaining tightness under the action of combined tensile loads (up to 379.9 kipf), compression (at least 80%) and internal hydraulic pressure (up to 5.076 ksi) due to mating the threaded profile and two thrust elements "metal-to-metal".
- The high-strength, high-hermetic threaded joint TMC1-SRV2 is characterized by high compression, tension and bending capacity and meets the requirements level of CAL IV (the highest level of connection application) of GOST R ISO 13679-2016 (analogue of ISO 13679:2002 Petroleum And Natural Gas Industriesprocedures For Testing Casing And Tubing Connection), which confirms the possibility of its use in the most difficult conditions of oil production. Furthermore, a feature of the TMC1 SRV2 threaded connection is that it can be assembled on an inclined rig mast.
Advantages
