The invention relates to a pipeline mounting support with a novel structure. The pipeline mounting support mainly comprises a short T-shaped seat frame formed by mutually welding a seat plate made of a steel plate and strip steel plate supporting legs, a thin steel strip opening ring-shaped hoop, a fastening expansion bolt for fixedly arranging the seat plate on a structural column, a fastener for interconnecting the seat frame and tightening the hoop, and a pipeline damping gasket. A pipeline is stably held in the hoop under the condition that the hoop is tightened by the fastener and elastic damping is limited so that the influence of environmental interference can be avoided, the mounting construction quality and the normal service life of a pipeline system after mounting are ensured, the use cost expenditure of daily maintenance can be obviously reduced, the connection junction point between the pipeline and the hoop is located at the inner side of the pipeline, the peripheral surface is smooth, overall integration is achieved, no interference protrusion exists, compared with existing like products, the pipeline mounting support obviously has the advantages that the structure is simple, scientific and reasonable, field mounting is convenient, the stability is high, the work is safe and reliable, the interference to the outside is small, and the requirements of high-efficiency, high-quality and low-cost construction and safe production and use can be met.
