Jamnagar refinery expansion

Located in the Gujarat, in western India, the Jamnagar refinery is the largest in the world in production capacity. Owned by Reliance Industries, it has been commissioned in 1998 and spreads over the 50 km2 surface area.

For the phase 3 alone, more than 305,000 tons of steel reinforcement were used: a 36 months project involving more than 100,000 engineers and construction workers.

Dextra has been involved in Jamnagar since the early days and supplied its rebar splicing solutions on the phases 1, 2 and 3 of the project.

For the phase 3 especially, 3 rebar coupler solutions were used:

Bartec solution was used for cast in situ applications, for bar-to-bar connections in foundations, pile cages, column cages. Bartec couplers were also used as a way to splice bars in heavily congested rafts and pile caps.

For the pipe-racks, which were built from precast elements, from a precast factory part of the project. Groutec couplers have been used to connect beams and columns. Positionned in the bottom elements and filled with grouts, they conveniently avoided the need of in situ wet joint.

For other applications where rebar length is too short to allow traditional overlap, Unitec couplers were used.
