PROJECT DESCRIPTION
Kazakhstan’s oil and gas chemical industry is actively developing, with large investment projects being implemented. At present, the country already operates the KPI polypropylene plant. The main feedstock – propane from Tengiz – is delivered to the KPI plant by rail. However, ethane for the future polyethylene plant cannot be transported in this way due to its physicochemical properties and strict storage requirements. The construction of trunk pipelines is the most economical and safe solution for transporting both products. The trunk pipeline project provides for the simultaneous and uniform transportation of both products, ensuring stabil... Read more

Location
Locations shown on the map are for indicative purposes and may vary from actual locations.
Other important details
Workforce: More than 500 workers will be involved during the construction phase. Around 170 specialists, including qualified local personnel, are expected during the operation period.
Project Stages: The completion of the feasibility study paves the way for the design and construction of the main pipelines. The project will create a single technological chain (GSC – Main Pipelines – Petrochemical Plants) for efficient processing and transportation of high-value products.
Cryogenic Risks: In case of product release, temperatures can drop sharply to –100 °C for ethane and slightly lower for propane. Strict compliance with material, equipment, and operational requirements is needed to prevent cryogenic points and accidents.
Pipeline Installation and Protection: The pipeline will be laid underground at a depth of up to 1.5 m. Factory-applied insulation with reinforced external protection and additional insulation for welded joints will be used, along with standard measures for electrochemical protection and safety along the entire route.
