Due to low costs, pipelines are commonly used for transporting hazardous substances such as combustible liquids and gasses. Currently, chemical industrial parks gas production stations have dense pipeline networks. In the case of a leakage subsequent fire accident, adjacent could be directly impinged by flame or engulfed in hot smoke, with potential result chain accidents catastrophic consequences. It is thus practical importance develop an efficient thermal protection material pipelines. this study, new type bio-based gel was prepared protection, using guar gum (GG) gelling agent, sodium tetraborate (B) crosslinking agent magnesium chloride (MgCl2) retardant. Firstly, orthogonal experiments were conducted examine time determine optimal formulations that meet requirements. Subsequently, water retention, stability microstructure these analyzed. Finally, performance evaluated under direct impingement flames high-temperature smoke. The results indicated best achieved formulation GG, B MgCl2 mass fractions 2.5, 0.6 0.5 wt%, respectively. This also exhibited retention capacity stability. experiments, effective times 216 s (for 90 mm diameter) 312 120 lower part impingement. Under smoke impingement, showed excellent performance. These research findings can provide important foundation further development materials conditions.
