Three exposure conditions were considered: hydrothermal aging in superheated water, thermal-oxidative aging in dry air, and hydrocarbon-medium exposure. Superheated-water immersion for up to 1000 h, dry-air aging for 168 h, and 7-day hydrocarbon exposure were used to describe changes in tensile properties, Shore hardness, mass, and thickness. Complete replicate records were available only for the thermal-oxidative aging dataset; therefore, most hydrothermal and hydrocarbon-medium results are reported as descriptive summary data. In the recorded data, EPDM formulation CL-2-1 retained approximately 89% of its tensile strength after 1000 h in superheated water. Sample L showed a smaller mean tensile-strength decrease than Sample Z after 168 h at 150 \u00b0C in dry air. In the hydrocarbon-medium summary data, XL95A\/05B-S1 showed lower mass increase and smaller tensile-strength and yield-stress decreases than PERT XRT70H across the tested temperature range. The Communication provides case-specific screening evidence and identifies the need for replicated testing, statistical analysis, longer aging series, and structural characterization before general material-selection or durability conclusions are made.<\/jats:p>","DOI":"10.3390\/polym18121524","type":"journal-article","created":{"date-parts":[[2026,6,19]],"date-time":"2026-06-19T09:18:43Z","timestamp":1781860723000},"page":"1524","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Accelerated-Aging Screening Data for Polymer Liners in Oil and Gas Flexible Composite Pipes: A Communication"],"prefix":"10.3390","volume":"18","author":[{"given":"Pingyuan","family":"Xia","sequence":"first","affiliation":[{"name":"Jiangsu Zhengdao Ocean Technology Co., Ltd., Nantong 226000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tianyi","family":"Ma","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Southeast University, Nanjing 211189, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lin","family":"Lei","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Southeast University, Nanjing 211189, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qingxia","family":"Wang","sequence":"additional","affiliation":[{"name":"Jiangsu Zhengdao Ocean Technology Co., Ltd., Nantong 226000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaomin","family":"Lu","sequence":"additional","affiliation":[{"name":"Jiangsu Zhengdao Ocean Technology Co., Ltd., Nantong 226000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaolin","family":"Zhu","sequence":"additional","affiliation":[{"name":"Jiangsu Zhengdao Ocean Technology Co., Ltd., Nantong 226000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6484-7257","authenticated-orcid":false,"given":"Yan","family":"Yan","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Southeast University, Nanjing 211189, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2628-3443","authenticated-orcid":false,"given":"Jiaqiao","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Southeast University, Nanjing 211189, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,6,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"279","DOI":"10.2516\/ogst\/2013211","article-title":"Evaluation of Long Term Behaviour of Polymers for Offshore Oil and Gas Applications","volume":"70","author":"Davies","year":"2015","journal-title":"Oil Gas Sci.
