Pipeline Technique Ka has commenced production welding on Tengizchevroil (TCO), Future Growth Project, Kazakhstan. 

Welding development and qualification were completed at the Pipeline Technique development center in Scotland, under contract to TCO, on the 14” OD x 57.5mm wall thickness X60 pipeline material using Pipeline Technique’s in-house Halo Auto GTAW and PGMAW / GSFCAW welding systems. 

The automatic Halo GTAW equipment has been developed for this heavy wall project, to perform the welds in a J-Bevel with 1° angle.  

The production scope in Tengiz will last 2 year and will cover 30km of HPHT pipeline below ground with associated above spools and anchor flanges components. 

As part of the scope, Pipeline Technique will also support training and qualification of local welders.
