The invention provides a delivery pipe in a solar heating system, belongs to the technical field of machines, and solves the technical problem of great loss of the delivery pipe in an existing solar heating system. The delivery pipe in the solar heating system comprises an outer pipe and an inner pipe, wherein the inner pipe is arranged in the outer pipe; a gap is reserved between the inner pipe and the outer pipe; end covers are fixed on the end parts of the inner pipe and the outer pipe; a mounting hole is formed in the outer pipe; a valve is mounted in the mounting hole; a heat storage material is also arranged in the gap and is prepared from the following raw materials in percentage by weight: 30-35 percent of silicon oxide, 7-10 percent of aluminium oxide, 0.3-0.5 percent of ferric oxide, 0.5-0.9 percent of calcium oxide, 0.4-0.6 percent of magnesium oxide, 1-3 percent of potassium oxide, 1-3 percent of sodium oxide, 2-5 percent of zinc oxide, 4-7 percent of coal ash, 1-3 percent of blind hole perlite microbeads, 0.1-0.3 percent of hexa-hydrated magnesium chloride, 0.5-0.9 percent of sodium carboxymethylcellulose, 0.6-0.9 percent of carboxymethylcellulose, and the balance of water. The delivery pipe in the solar heating system has the advantages of effectively reducing the loss of energy and improving the delivery efficiency of the delivery pipe.
