class=\"dc-mb-3\"> A subsea-equipment and offshore-processing supplier was qualifying supply of two demanding material groups: Inconel 625 pipe for subsea flowlines exposed to sour produced fluids, and CuNi heat-exchanger tubes for seawater cooling. The previous supplier could not consistently provide corrosion-related chemistry documentation, risking requalification against the operator&#8217;s material requirements. <\/p>\n<p class=\"dc-mb-3\"> DZX qualified with Inconel 625 pipe including complete chemistry and mechanical documentation aligned to sour-service requirements, and CuNi tubes with verified chemistry for seawater service. One auditable source covered both subsea and topside systems. <\/p>\n<\/div>\n<section class=\"dc-case-facts\" aria-label=\"Project details\">\n<div class=\"dc-row dc-py-md-3 dc-justify-content-center\">\n<div class=\"dc-col-md-10\">\n<div class=\"dc-card-box\">\n<p class=\"dc-mb-2\"> This case summarizes the application requirements, materials supplied by DZX and delivery value.
