Ice blockage issues in pipeline shutoff systems

Our company has supplied wellhead safety control systems for a project in Jilin. The extreme temperatures at the site over the years have ranged from -36.1°C to 39.3°C; to address the issue of ice blockage in the pipeline pressure-taking sections, we used isolators. Our pipeline isolation system that directly uses pipeline gas drive will now be applied to the pipeline networks in Xinjiang. The climate conditions there also present the issue of ice blockage, but for this project we cannot use isolators – so how should this problem be resolved? The diameter of the pipeline is DN300 PN6.3Mpa, and our pressure tapping valve is 1/2". We also ask fellow sailors to share their opinions more.
