(modified gasometric) threaded connection
Pervouralsk New Pipe Plant's Finishing Centre (part of ChelPipeGroup) produced a pilot batch of modified ChT-VTm1 gas-tight threaded connection tubing with a diameter of 73.02 mm and a wall thickness of 5.51 mm at the request of Gazpromneft-Orenburg.
With a total volume of 62 t, the ChT-VTm1 threaded connection tubing was made of corrosion-resistant and H2S-resistant 18 chromium–molibdenum–vanadium–niobium steel for fields with up to 6% H2S and CO2 content.
The ChT-VTm1 premium threaded connection is an alternative to the ChT-VT threaded connection, featuring modified thread parameters and serving as a substitute for imported VAGT connections by Voestalpine (Austria) and NEW VAM by Vallourec (France).
