The Double-Pipe Heat Exchanger is a mission-critical piece of process equipment serving Yemen's Yemen LNG plant at Balhaf gas processing and export operations and Aden Refinery crude oil processing and products distribution infrastructure, specifically engineered to achieve counter-current heat exchange through concentric pipe-in-pipe hairpin configuration within the frameworks of Yemen's hydrocarbon sector recovery and LNG export infrastructure rehabilitation. Every Double-Pipe Heat Exchanger destined for Yemen is engineered and certified to ASME VIII, API 650, Yemen Standardization Organization (YSO), British BS heritage, providing Yemen Standardization Organization (YSO) and Ministry of Oil and Minerals with the inspection documentation required for pressure equipment commissioning approval. Engineered for hot coastal tropical humidity at Aden and Hodeidah, semi-arid highland conditions at Sana'a specific to Yemen's industrial zones, the Double-Pipe Heat Exchanger is fabricated from carbon steel, duplex 2205, titanium, or Hastelloy C-276 selected for process fluid corrosivity, ensuring structural integrity and performance consistency throughout its design service life.

Yemen's Yemen LNG plant at Balhaf gas processing and export operations sector applies the Double-Pipe Heat Exchanger specifically for specialty chemical and pharmaceutical API synthesis cooling and temperature control, complemented by its critical role in high-pressure supercritical extraction and aromatic hydrocarbon process cooling across the Aden Refinery crude oil processing and products distribution and Marib gas processing plant and pipeline infrastructure segments. Yemen LNG, Yemen Oil and Gas Corporation, and Aden Refinery Company — representing the premier industrial operators in Yemen — select the Double-Pipe Heat Exchanger rated to pressures to 500 bar and temperatures from -100°C to +600°C in multi-hairpin scalable configurations for integration into their critical production and utility systems. A key differentiator for Yemen's demanding industrial services is true counter-current flow achieving minimum temperature approach with expanded multistage hairpin capacity — achieved through rigorous design to ASME B31.3 process piping, TEMA standards, and ASME VIII Division 1 and validated by third-party inspection certification.

Nord supplies Yemen customers with complete engineering documentation — including design calculations, weld maps, NDE records, pressure test certificates, and inspection dossiers — fully compliant with Yemen Standardization Organization (YSO) and Ministry of Oil and Minerals standards.
